How to take good care of all kinds of study stationery

Abstract: school supplies refer to the appliances commonly used in learning. From the category, school supplies can be mainly divided into two categories: traditional school supplies and electronic school supplies. So, how to clean and maintain school supplies? Let's have a look. Pen cleaning and maintenance

1. If there is ink in the pen, drain it first, then pinch the pen container repeatedly, and rinse the pen with warm water several times until the water is clear. Wipe off the water outside the pen with a dry cloth. If necessary, remove the nib, tongue, pen holder and pen container in turn and clean them. Because different pens have different structures, it is good to disassemble the difficult pens in the first step. Install the nib, tongue, pen holder and pen container in turn, and then dry the water outside the pen with a dry cloth. Fill the pen with water and leave it for a period of time, which is beneficial to the full dissolution of dry ink in the pen. Drain all the water in the pen, let it dry naturally, and then it can be stored. Don't add acidic substances to clean water, otherwise it will damage the pen. The brand of ink should be fixed. When switching to another ink, it should be cleaned before use.

2, in the process of cleaning the pen, it is a process that needs to be carefully decomposed. Don't break the pen, because all the parts in the pen are fragile. You need to be patient and careful when cleaning the pen, otherwise it will cause ink residue. Be sure to protect the nib.

Cleaning and maintenance of desks

1. Children's study tables should be protected from direct sunlight. When high-temperature objects are placed on furniture, they must be padded with insulation pads to avoid affecting their service life. The desk should be placed in a well-lit place. If the child's desk and chair are placed horizontally, the light should come from the left. Children's desks and chairs should be as few as possible and placed against the wall to expand children's activity space;

2. Children's study tables should not be stained with colored water or acid-base solutions. If it is filled with water, dry it immediately with a dry cloth. If stained with colored liquid or other harmful liquid, it should be dry-cleaned or washed immediately according to the requirements of furniture label. Do not wash and bleach. If you find the thread loose, don't pull it with your hands, but cut it neatly with scissors.

3. Before using the wooden children's learning table, if the structure is found to be loose, tighten the connecting fasteners. When cleaning the dust, use a soft cloth to clean the dust along the wood grain. Clean the soft cloth with some cleaning agent, and don't wipe it with a dry cloth to avoid scratches. It is also inappropriate to clean furniture with alkaline water or boiling water, or place high-concentration alcohol to avoid damaging the surface of furniture;

4. It is not appropriate to hit children's desks and chairs with heavy objects at ordinary times, nor to mop the surface, nor to cut things on the surface of children's desks and chairs, nor to apply gravity to clean the surface. It is also inappropriate to repair furniture with pigments different from the original paint color of furniture. Every other year, the children's study desk should be brushed with water to keep the color bright.

Cleaning and maintenance of schoolbags

1. Maintenance points of canvas and cotton bag: soak in salt water 15 minutes, scrub with soap and soft brush, hand wash at low temperature, air dry on the reverse side, iron at medium temperature, pay attention to products containing leather, avoid sun exposure, and remove movable accessories before cleaning.

2, leather bag: a periodic layer of neutral plant maintenance oil, the simplest daily maintenance method. Don't overload: leather is an organic matter. Long-term overload and overload will cause leather overstretching, elastic fatigue and deformation.

Cleaning method of pencil box

Washing: the pencil case can be washed like clothes, which is more durable than clothes.

Use washing powder: for ordinary dirty things, you can soak and scrub with washing powder.

Use disinfectant: As a routine stationery, the pencil case will be contaminated with more bacteria and can be disinfected with disinfectant. At the same time, it also has the function of decontamination.

Use oxalic acid: For difficult stains such as ballpoint pen stains, oxalic acid can be used. Oxalic acid is a strong organic acid with strong decontamination effect. You need to wear gloves when using.

Soaking: Put the pencil case in water, add the necessary detergent and soak it, and the pencil case will become easier to clean.

Dry: After cleaning the pencil case, remember to hang it in a sunny and ventilated place to dry.

Maintenance method of learning machine

1, pay attention to waterproof. All electrical products have the same feature, that is, they can't enter water. There are IC appliances, DC circuit, touch screen and the joint of the shell in the learning tablet computer is not waterproof. So once the learning tablet falls into the water, or water is put on the learning tablet, it is possible that the water will fall into the circuit board, causing short circuit and leakage between IC pins. Once there is leakage, whether it is Taiqi notebook or other learning machines, there will be abnormal noise.

2. Note that hard objects are all plastic products, and even the better step-by-step learning tablet computer is also a plastic case. If you hit the shell with a hard object, it is likely to smash or break the shell, seriously damaging the circuit board and failing to work normally. Or it may cause the notebook parts of Taiji machine to fall off and make abnormal noise when shaking.

3. Please turn off the battery before inserting the SD card. Usually, when inserting the SD card, you should turn off the power first, then turn on the power, because the SD card can always be hot-swapped, but sometimes you can't read the contents of the SD card because of the friction between the copper sheet of the SD card and the copper sheet of the learning tablet or the instantaneous power failure. Therefore, turning on the power supply after plugging in can avoid these problems, thus protecting the service life of the SD card.
