How to generate static electricity?

Question 1: What is static electricity and why is it generated? In winter, we often encounter such a phenomenon: getting up in the morning to comb my hair, my hair is getting messy and even "angry"; When friends meet, the fingertips touch, just like being stung by a bee; Turn off the lights at night, take off your clothes and get ready for bed. In the dark, you sometimes hear crackles, accompanied by blue flashes ... these phenomena are all the results of static electricity. Static electricity is invisible and intangible. It is attached to the surface of an object and only releases energy when interacting with other objects. Static electricity produced by human body is mainly caused by two reasons: first, air drying; The second is non-conductive chemical fiber clothing. Especially in winter, people will feel more static electricity on their bodies. This is because the winter climate in most parts of China is very dry, and the dry environment is more conducive to the accumulation of static electricity. Studies have shown that any two objects with different materials will generate static electricity after contact, so when we are active, the static electricity on our bodies is mainly caused by the friction between clothes or between clothes and our bodies. And wearing clothes of different materials is also somewhat different. For example, clothes made of chemical fiber are more likely to generate static electricity, while clothes made of cotton generate less static electricity. Modern cities also have dense high-rise buildings, and most of the houses are reinforced concrete. Coupled with the use of a large number of electrical facilities, indoor static electricity accumulation is not easy to release, and it can generate strong static electricity, making people live in more and more strong static electricity. Although experiments have proved that people will not feel uncomfortable when the electrostatic voltage is 50 thousand volts, static electricity does have many negative effects on human health. For example, excessive electrostatic accumulation in the human body will affect the central nervous system, causing dizziness, headache, insomnia, irritability and other symptoms. For another example, some people with arrhythmia can't find out the causes of organic diseases and arrhythmia, but after listening to the doctor's advice to change into pure cotton clothes, their heart rhythm will soon return to normal. In addition, electrostatic adsorption of a large number of floating dust mixed with a variety of pathogenic bacteria is very easy to spread infectious diseases such as influenza, hepatitis and tuberculosis. So, how to eliminate static electricity in daily life and avoid its harm? Dealing with static electricity can start with "prevention" and "discharge". Let's talk about how to "prevent" static electricity. We should try to choose pure cotton products as fabrics for clothes and home decorations, and try to avoid using chemical fiber carpets and furniture made of plastic to prevent friction and electrification. There should be as few discharges as possible in the bedroom to prevent inductive electrification. In addition, indoor ventilation should also be paid attention to frequently. "Discharge" is to increase humidity and let local static electricity be released. Static electricity accumulated in the body can be consumed by output. For example, walking barefoot indoors and letting your feet directly touch the ground to release static electricity accumulated in the body; Wash your hands before going out, or put your hands on the wall to remove static electricity before opening the door; When turning off the TV or leaving the computer, you should wash your hands and face immediately to let the static electricity on the skin surface be released in water. In addition, in winter, using humidifier to keep indoor humidity is also a good way to release indoor static electricity. In addition to using humidifiers, keeping ornamental fish and daffodils indoors can also adjust the indoor humidity, which is conducive to the release of static electricity. Inside the house, the carpet may generate static electricity after rubbing the sole, and the wind outside the house may also make the body charged. At this time, when you go in and out to touch the iron gate, your hand is likely to be electrocuted. Therefore, when touching the iron gate, don't touch the iron gate directly with your hands, but let your hands grasp a bunch of keys in your pocket in a large area (usually this is not subject to static electricity), and then touch the iron gate with the tip of the key, so that the static electricity on your body will be discharged. Also, when you get out of a taxi, you are often entangled in static electricity. It is mainly the static electricity accumulation caused by the friction between the body and the seat when you get off the bus. When you close the door after you get off the bus, your hand will suddenly touch the iron gate and get static electricity. Therefore, it is best to hold the metal door frame in advance before the body leaves the seat completely, so as to discharge the static electricity from the body at any time, so as to avoid sudden static electricity when the hand touches the iron gate after getting off the bus. Finally, I would like to remind you that taking a bath and changing clothes at ordinary times can effectively eliminate static electricity and charged dust accumulated on the surface of the human body. Eating more vegetables, fruits, yogurt and other foods, drinking more water, and paying attention to supplementing calcium and vitamin C can also reduce the adverse effects of static electricity on the body.

Question 2: Under what circumstances is it easy to generate static electricity? When winter comes, it is often disturbed by static electricity, which is quite uncomfortable.

When the human body is active, the friction between skin and clothes, and the friction between clothes will generate static electricity. With the increase of household appliances and the increase of people wearing chemical fiber clothes in winter, the electrostatic charges generated by household appliances will be absorbed and accumulated by the human body. In addition, the walls and floors of the room are mostly insulators, and the air is dry, which is more susceptible to static interference.

Because the skin of the elderly is relatively dry than that of the young, and the cardiovascular system of the elderly is aging, the anti-interference ability is weakened, and the elderly are more susceptible to static electricity. In the elderly with various diseases of cardiovascular system, static electricity will aggravate the condition or induce arrhythmia such as ventricular premature beats. Too much static electricity often makes people fidget, headache, chest tightness, dyspnea and cough.

In order to prevent the occurrence of static electricity, it is necessary to maintain a certain humidity indoors, often mop the floor, often sprinkle water, or humidify with a humidifier; Take a bath and change clothes frequently to eliminate the static charge accumulated on the surface of human body. When you find that your hair can't be combed, soak the comb in water for a while, and then comb your hair after the static electricity is eliminated. After taking off your clothes, gently touch the wall with your hands, and touch the wall with your hands before touching the door handle or faucet to "discharge" the static electricity in your body, so as not to hurt you. For the elderly, we should choose soft and smooth cotton textiles or silk underwear, and try our best to reduce the harm of static electricity.

1, wash your hands before going out, or put your hands on the wall first to remove static electricity! Try to put on beautiful clothes.

2. In order to avoid electrostatic strike, you can use small metal devices (such as keys) and cotton cloth to touch doors, door handles, faucets, chair backs, bed railings, etc. To eliminate static electricity, and then touch them with your hands.

3. Wear cotton underwear.

4. When you are ready to get off, hold the gear with your right hand, then touch the iron part below with your fingers, then open the door, and put your left hand on the iron part of the door, but don't let go of your left hand, then let go of your right hand and get off. At this time, if you hold the door with your right hand, you will not get an electric shock. . Then push hard and it's done ~ ~

5. To deal with static electricity, we can adopt both "prevention" and "release". "Prevention", we should try to choose pure cotton products as fabrics for clothes and home decoration, and try to avoid using chemical fiber carpets and furniture with plastic as surface materials to prevent friction and electrification. Try to stay away from TV, refrigerator and other electrical appliances to prevent induction electrification. "Discharge" is to increase humidity and make local static electricity easy to release. When you turn off the TV and leave the computer, wash your hands and face immediately, so that the electrostatic charge on the skin surface can be released in the water. Try to choose high moisturizing cosmetics in winter. Commonly used humidifier. Some people like to keep ornamental fish and daffodils indoors, which is also a good way to adjust indoor humidity.

In addition, I recommend an economical and practical humidification method: put a basin of water under the heating, use an old towel (or absorbent cloth), put one end in the water and the other end on the heating, so that about three liters of water can be evaporated into the house day and night. If every heater does this, the whole room will feel damp and pleasant. it wont hurt you to try it

6. Bathing and changing clothes frequently can effectively eliminate the static electricity accumulated on the surface of human body.

In daily life, people sometimes accumulate static electricity because of clothes, climate, friction and other reasons. And when they suddenly come into contact with metal, they will feel the pain of electric shock, and even when it happens frequently at a certain stage, it will cause certain psychological pressure. If you avoid contact with iron for a while, you may accumulate more charges and get a bigger electric shock sooner or later.

Here are two tips to help prevent this kind of electric shock.

When touching the iron gate, don't touch the iron gate directly with your hands. Instead, grab a bunch of keys in your pocket with your hand (usually it won't get an electric shock), and then touch the iron gate with the tip of the key, so that the electricity on your body will be discharged without getting an electric shock.

Principle: The pain of hand discharge is caused by high-voltage discharge. When discharging, the hand suddenly touches the iron gate very little, resulting in instantaneous high voltage. If you take the key out of your pocket, first press the key in a large area (a string of keys itself can't transfer much charge, so it won't get an electric shock at this time), and then use the key tip to touch the big conductor. At this time, the contact point of discharge is not a certain point on the skin of your hand, but the tip of the key, so your hand will not feel pain (maybe the key will! -If it hurts.

2. You often get an electric shock when you get off a taxi. The main reason is that the friction between the body and the seat produces static electricity accumulation when getting off the bus, and the hand suddenly protrudes when closing the door after getting off the bus ... >>

Question 3: How to generate strong static electricity? As we all know, what computer equipment fears most is static electricity, and seemingly insignificant static electricity can also cause permanent damage to computer chips. Since computers are so afraid of static electricity, why do computer equipment still generate static electricity? In junior high school, we know that friction can generate electricity, and rubbing on fur with a glass rod can generate static electricity, and its voltage is as high as several thousand volts or even tens of thousands of volts. Similarly, the chemical fiber products we wear and the chemical fiber carpets laid on the ground will also generate static electricity during exercise, so when we come into contact with metal objects connected with the earth, we sometimes feel electric shock. Don't underestimate such a slight electric shock. If you discharge a computer chip, your computer will rest forever. How is static electricity generated? In addition to the above chemical fiber clothing and carpets, monitors, switching power supplies, soldering irons, mobile phones and so on. It will generate static electricity. 1, CRT display has a high voltage of about 30000 volts. At work, due to the principle of Ferrari container, high voltage will generate certain charges on the surface of the display screen. If the surrounding environment is dry and the charge cannot be discharged, it will form a positive charge with higher voltage after long-term accumulation. So sometimes we get an electric shock when we touch the surface of CRT. 2. Switching power supply and some accessories will radiate a large number of high-frequency electromagnetic waves to the surrounding area when working. If there are metal objects around, these electromagnetic waves carrying energy will be absorbed by metal objects such as the case, and some of them can be converted into heat (this is the principle of microwave ovens), and some of them will be converted into charges and accumulated on the metal surface (or it is reported that the electricity generated on the moon can be transmitted to the earth by microwave in the future). If the metal object is ungrounded or poorly grounded, this part of charge will increase with the accumulation of time. If there are suitable conditions, it will discharge. 3. The surface of soldering iron will also be charged, and the general maintenance personnel know this truth. Otherwise, you can test the heating soldering iron with an electric pen, and the light of the electric pen will light up. This part of the charge is mainly due to the large resistance of the insulation layer of the resistance wire inside the soldering iron when it works at high temperature. At this point, a small amount of charge will drift to the surface of the soldering iron, making the soldering iron charged. In this case, we can reverse the power plug of the soldering iron 180 degrees and then plug in the power supply, and the surface charge will be reduced a lot. However, when using 220V soldering iron to solder CMOS components, for safety reasons, it is necessary to ensure that the soldering iron is well grounded, or to solder after the soldering iron is cut off. When mobile phones and walkie-talkies are working, they will emit a lot of radio waves into space. Because mobile phones and walkie-talkies work at high frequency, they will emit more energy. You can try it if you are interested. 3W walkie-talkie can light 12W energy-saving lamp, and 40W fluorescent lamp can also be slightly lit. Static electricity will also be generated around. So when we make a phone call, it's better not to take too long. Now that we know that the harm of static electricity is so serious, how to effectively prevent the loss caused by static electricity? 1, for the safety of computer equipment, for schools or other qualified units, when computers are used collectively, anti-static floors must be laid in the computer classroom, and ordinary chemical fiber carpets must never be used. 2. The power ground wire used by computer equipment must be well grounded. It is recommended to use a three-hole power socket. Of course, the power cord must also be three-pin. Some friends use a line to connect the outside of the chassis with the ground or water pipes, and it can't achieve good results. 3. If there is no grounding equipment, when we want to touch the board by hand, we must touch the tap water pipe or the wet ground with our hands to release the static electricity we carry, so as to avoid the damage of the board caused by personal discharge when touching the board. Especially in the dry and cold winter, we wear mostly wool chemical fiber products, which are most likely to generate static electricity.

Question 4: It is often easy to generate static electricity. What happened? It's a dry climate, not a physical condition. You can do it in the following ways, which is very useful!

How to prevent static electricity?

Are we helpless about this ubiquitous static electricity? Don't worry, we'll figure something out.

Keep a certain humidity. Keep some potted plants or ornamental fish in the room. You can also use a humidifier to increase the humidity in the room. If these conditions are not met, you can also sprinkle some water in the room, put a basin or two of clear water or mop the floor frequently. I recommend an economical and practical humidification method: put a basin of water under the heating, use an old towel (or absorbent cloth), put one end in the water and the other end on the heating, so that about 3 liters of water can evaporate into the house day and night. If every heater does this, the whole room will feel damp and pleasant.

Self-made ground wire You can use a metal wire as the ground wire of other electrical appliances such as a TV set to help the electrical appliances evacuate the static electricity generated through this ground wire.

It is suggested that the elderly, children, sensitive person, patients with heart disease who can't find the cause, neurasthenia and mental patients should use pure cotton or pure wool instead of chemical fiber. It is recommended to wear pure cotton underwear in winter, and use natural textiles for quilts, sheets and quilts, so as to avoid clothes made of chemical fiber as much as possible and reduce the adverse effects of static electricity on people. Chemical fiber carpet is also the chief culprit in making static electricity, so it is best to choose pure cotton fabric or pure wool fabric when choosing these items, which will reduce some static electricity. mutually

Wash your hands and face frequently. Don't put the TV in the bedroom. When watching TV, people should open the window and keep a distance of 2-3 meters from the TV. Because electrostatic dust will gather on the skin, you must wash your hands and face after watching TV or using the computer.

There are also some tips to avoid static electricity. For example, you can use small metal devices (such as keys) and cotton rags to touch doors, door handles, faucets, chair backs and bed railings to eliminate static electricity, and then touch them by hand.

Taking a bath and changing clothes often can effectively eliminate the static electricity accumulated on the surface of human body.

When the hair can't be combed, soak the comb in water and comb it at will after the static electricity is eliminated. Try to use moisturizing lotion or conditioner when washing your hair.

Barefoot is beneficial to the electrostatic discharge accumulated on the body surface. Therefore, in leisure, don't miss every opportunity of barefoot.

Eat more acidic foods such as vegetables, fruits and yogurt, drink more water, supplement calcium and vitamin C, and reduce the influence of static electricity.

By the way, static electricity is also very harmful to petrochemical enterprises, especially gas stations Electrostatic charge is easy to accumulate on the refueling gun, and sparks are easy to generate when refueling. Therefore, it is best to release the static charge on the refueling gun before refueling, such as touching the refueling gun with surrounding metal objects.

Question 5: The four main sources of static electricity can be roughly divided into two categories:

1. Static electricity on the chip and PCB: After the chip is dried, some static electricity will be accumulated due to factors such as surface drying, hot air blowing and friction with the conveyor belt. However, the chip's antistatic ability is very weak, and several hundred volts of static electricity may cause breakdown and damage the chip;

2, static electricity on the human body: human friction will bring static electricity, contact chip inspection is easy to cause discharge breakdown, so the electronics industry should do a good job of human protection.

Question 6: How is static electricity generated and how to eliminate it? Matter is made up of molecules, molecules are made up of atoms, and atoms are made up of negatively charged electrons and positively charged protons. Under normal circumstances, an atom has the same number of protons and electrons, so it is not charged. Electrons surround the nucleus, and once they are forced out of orbit, they leave the original atom and invade other atoms B. Atom A is positively charged due to the lack of electrons, which is called cation, and atom B is negatively charged due to the increase of electrons, which is called anion. The reason for the uneven distribution of electrons is that electrons are out of orbit due to external forces, which include various energies (such as kinetic energy, potential energy, thermal energy, chemical energy, etc.). ). In daily life, any two objects with different materials will generate static electricity after contact out. When two different objects touch each other, one object will lose some charges, for example, electrons will be transferred to the other object to make it positively charged, and the other object will get some remaining electrons to be negatively charged. If it is difficult to neutralize the charge in the separation process, the charge will accumulate and make the object electrostatic. Therefore, when an object contacts and separates from other objects, it will be charged with static electricity. Usually peeling off a plastic film from an object is a typical "contact" electrification, and the static electricity generated by undressing in daily life is also a "contact" electrification. Solids, liquids and even gases will be charged with static electricity due to contact. This is because gas is also composed of molecules and atoms. When air flows, molecules and atoms will also produce "contact" and electricity. We all know friction electrification, but we seldom hear of contact electrification. Triboelectrification is essentially a process of contact and separation, resulting in the imbalance of positive and negative charges. Friction is a process of continuous contact and separation. Therefore, triboelectrification is essentially contact electrification. In daily life, all kinds of objects may generate static electricity due to movement or friction. Another common electrification is induction electrification. When a charged object approaches an uncharged object, it will induce negative electricity and positive electricity at both ends without electrical conductor. In dry and windy autumn, we often encounter this phenomenon in our daily life: when we take off our clothes and sleep at night, we often hear a crackling sound in the dark, accompanied by blue light. When you meet and shake hands, as soon as your fingers touch each other, you will suddenly feel the tingling of your fingertips, which is shocking; When I get up in the morning to comb my hair, my hair tends to "float", and the more I manage it, the more chaotic it is. When you pull the door handle and turn on the tap, you will get an electric shock, and you will often make a "bang, bang" sound. This is static electricity generated in the human body. All the above phenomena are the result of the external "discharge" of static electricity in the body. How to prevent static electricity [edit this paragraph] When people are active, skin rubs against clothes and clothes, which will generate static electricity. With the increase of household appliances and the increase of people wearing chemical fiber clothes in winter, the electrostatic charges generated by household appliances will be absorbed and accumulated by the human body. In addition, the walls and floors of the room are mostly insulators, and the air is dry, which is more susceptible to static interference. Because the skin of the elderly is relatively dry than that of the young, and the cardiovascular system of the elderly is aging, the anti-interference ability is weakened, and the elderly are more susceptible to static electricity. In the elderly with various diseases of cardiovascular system, static electricity will aggravate the condition or induce arrhythmia such as ventricular premature beats. Too much static electricity often makes people fidget, headache, chest tightness, dyspnea and cough. In order to prevent the occurrence of static electricity, it is necessary to maintain a certain humidity indoors, often mop the floor, often sprinkle water, or humidify with a humidifier; Take a bath and change clothes frequently to eliminate the static charge accumulated on the surface of human body. When you find that your hair can't be combed, soak the comb in water for a while, and then comb your hair after the static electricity is eliminated.

For the elderly, we should choose soft and smooth cotton textiles or silk underwear, and try our best to reduce the harm of static electricity. 1, wash your hands before going out, or put your hands on the wall to remove static electricity, and try to * * * chemical fiber clothes. 2. In order to avoid electrostatic strike, you can use small metal devices (such as keys) and cotton cloth to touch doors, door handles, faucets, chair backs, bed railings, etc. To eliminate static electricity, and then touch them with your hands. 3. Wear cotton underwear. 4. When getting ready to get off, hold the gear with your right hand, then touch the iron part below with your finger, then open the door, and put your left hand on the iron part of the door, but don't let go, then put it down ... >>

Question 7: What are the three main causes of static electricity? Any substance is composed of atoms, and the basic structure of atoms is protons, neutrons and electrons. Scientists define protons as positively charged, neutrons as uncharged and electrons as negatively charged. Under normal circumstances, an atom has the same number of protons and electrons, and the positive and negative charges are balanced, so it is not charged. However, due to external effects such as friction or in the form of kinetic energy, potential energy, thermal energy and chemical energy, the positive and negative charges of atoms will be unbalanced. Friction in daily life is essentially a process of constant contact and separation. In some cases, static electricity can be generated without friction, such as induced electrostatic electrification, thermoelectric and piezoelectric electrification, Helmholtz layer, jet electrification and so on. Any two objects with different materials will generate static electricity after being separated, and the common method to generate static electricity is friction electrification. The better the insulation of the material, the easier it is to generate static electricity. Because air is also composed of atoms, it can be said that static electricity may be generated at any time and place in people's lives. It is almost impossible to completely eliminate static electricity, but some measures can be taken to control static electricity so that it does not cause harm.

The charge redistribution caused by friction is also formed by the charge redistribution caused by the mutual attraction of charges. Specifically, it is because all substances are made up of atoms, which have negatively charged electrons and positively charged nuclei. In general, the positive charge of the nucleus is equal to the negative charge of the electron, which is in balance, so it is uncharged. However, if the electrons are out of orbit by external force, the distribution of electrons is unbalanced. For example, triboelectrification is essentially a process that causes the imbalance of positive and negative charges. When two different objects touch and rub against each other, the electrons of one object are transferred to the other object, which is positively charged due to the lack of electrons, and the other object is negatively charged due to the remaining electrons, which is electrostatic.

Question 8: How static electricity is generated (be particularly simple and clear) (20 words) Different substances have different abilities to gain and lose electrons. When they contact, electrons transfer, and then they separate after contact, so static electricity can be generated.

Question 9: How to solve the problem of static electricity How to prevent static electricity in daily life?

1, try not to put or put less household appliances in the bedroom. This can prevent the human body and electrical appliances from generating an electric field at close range and contacting static electricity. It is best to watch TV 2 ~ 3 meters away from it.

2. Use a "third party" to eliminate static electricity. In order to avoid the influence of static electricity, small metal devices (such as keys) and cotton cloth can be used to touch the doors, door handles, faucets, chair backs and bed railings that can cause static electricity to eliminate static electricity, and then touch them by hand.

3. Use pure natural fabrics. Try to use natural textiles such as cotton, linen and silk for underwear, sheets and quilts, and try not to use or wear chemical fiber home textiles and clothing.

4, use a wooden comb to moisturize the hair. Comb your hair with a wooden comb and use conditioner when washing your hair, which can eliminate static electricity.

5. Keep the indoor temperature. Therefore, static electricity is not easily generated. It is best to use a humidifier indoors in winter, and you can also put flowers to avoid static electricity.

6. Floor, wall, ceiling, etc. Use antistatic materials.

7. Eat more vegetables, fruits, yogurt, drink more water, supplement calcium and vitamin C, and reduce the influence of static electricity. 8. Another point is that you can put your hand on the wall to export static electricity.

How do car owners prevent static electricity?

Install the electrostatic discharger. Electrostatic discharge devices are divided into grounding type and air discharge type, but according to experts, the current trend is to install both sets, so the effect of eliminating static electricity is much better than that of installing one set alone.

Spray anti-static spray. There is a new product called "anti-static spray". Spray it evenly on the car body and wipe it off with a towel, and the car will have a magical anti-static effect, and the validity period is not short!

Use less cosmetics. For female car owners, attention should be paid to minimizing the use of cosmetics in a dry environment. Heavy makeup will make the skin drier.

Turn on the air conditioner less. In particular, the internal circulation air conditioner makes it difficult to store a little water in the already dry car. It is recommended to leave the window half open (to avoid the wind blowing directly on your body), even if you have some slight sweat smell on your body. Properly promoting sweat gland secretion is better for the skin.

Spread a wet towel. Spread a wet towel on the dashboard, so that the water in the towel can be quickly evaporated by the sun, thus improving the humidity in the car.

Question 10: How to reduce static electricity in winter? Many people are often disturbed by static electricity when the weather is dry. Shake hands, pull the door handle, press the elevator button or even turn on the tap, which often causes a "bang, bang" sound, and the hand feels shocked. This is the discharge after the static electricity of human body accumulates to a certain amount. Nowadays, many people live in high-rise buildings, and the human body will absorb and accumulate electrostatic charges generated by various household appliances. In addition, indoor walls and floors are mostly nail-edged bodies, and such people are more vulnerable to electrostatic interference. Experts warn that static electricity is not just a bad feeling. In fact, it has a negative impact on people's health, so we should take appropriate precautions.

It has been confirmed by medical experts that skin electrostatic interference can change the normal potential difference of human body surface and affect the normal electrophysiological process of myocardium and the normal conduction of ECG. This static electricity will aggravate the patient's condition or induce premature beats, posing a potential threat to patients with severe neurasthenia, psychosis and heart disease. Persistent static electricity will also increase the alkalinity of blood, reduce the calcium content in serum and increase the excretion of calcium, which will lead to itchy skin and pigmentation, affect people's physiological balance and interfere with people's emotions. In addition, office white-collar workers who operate computers every day or people who stay in an environment with many household appliances for a long time often cause facial diseases such as erythema and pigmentation. This is all because of the static electricity generated by the electric field of computer screen or household appliances, which makes the microorganisms and dust in the air electrostatically adsorbed on the skin, and over time * * * the skin.

Relevant medical experts pointed out that people who accumulate more static electricity in their bodies can consume it through "output". People with more static electricity should wear chemical fiber clothing as little as possible, carry out anti-static treatment on chemical fiber clothing, choose pure cotton products or silk products for personal clothing and bedding, and try not to use chemical fiber carpets at home. Maintaining a certain humidity indoors, such as mopping the floor with a wet mop, sprinkling some water, or humidifying with a humidifier, is good for anti-static; You can also use a negative ion generator to neutralize some positive charges, or put a pot of cold water indoors or plant some potted flowers and plants. After using the computer or watching TV for a long time, you should wash your skin with soap in time to "drive away" the static electricity on your skin. In addition, we should also avoid staying in places with static electricity for a long time, such as the production room where computers are concentrated, to reduce the harm of static electricity to people.
