Is it more advantageous for car companies to switch to masks? A brief history of the birth of 0.5 second mask

Now the degrees of freedom are all calculated by masks.

"The world is facing serious confusion in the personal protective equipment market. The demand is 100 times higher than the normal level and the price is 20 times higher. " The World Health Organization (WHO) has warned that there is a serious shortage of global masks.

When the country is in danger, it is the time to test major enterprises. More than 3,000 companies that have nothing to do with VIVO, Mitsubishi, Gree and Daddy-Baby diapers have started to make masks. So do many car brands.

Among other things, many car companies have set aside their own factories to make masks. No, Wuling, BYD and GAC brand masks have already rushed to the front.

The hardest core is Wuling. Under the slogan of "what people need, what things want", in the case of shortage of medical materials, SAIC-GM-Wuling joint suppliers transformed the production line into masks, quickly completed the transformation of clean workshop and the debugging of the production line, and built the first fully automatic mask production line in Guangxi. At present, more than 1 10,000 masks have been produced.

BYD officially issued a military order of "equipment drawings within three days, equipment within one week and products within ten days". It is reported that BYD disposable medical masks will be off the assembly line in batches on February 17, and the gel-free disinfectant will also be off the assembly line. The daily output of disinfectant will reach 50,000 bottles, and it is estimated that the daily output of masks will reach 5 million by the end of the month. At the same time, Guangzhou Automobile Group has begun to inspect the manufacturers of mask production equipment and train relevant technicians.

It takes only 0.5 seconds to produce a mask in China, so it is not difficult to make a mask, as long as there are complete production systems, personnel, technical reserves, site requirements, financial strength, procurement channels and other conditions. For the automobile industry, enterprises have a natural advantage, because they have a stable supplier of raw material polypropylene.

Although the mask is so simple to make, it has gone through a long history since it was used for medical treatment and epidemic prevention.

The Origin of Ancient Masks-Zoroastrianism

Speaking of masks, the earliest recorded "mask-like objects" appeared in the 6th century BC. Zoroastrianism in ancient Persia believed that the smell of laity was unclean, so it was necessary to cover the face with cloth during religious ceremonies to prevent the smell from spreading.

At that time, masks had little technical content. Just tie a cloth on your face.

In Europe, the medical industry was dominated by wizards in the early years, and the real doctors were weak. When the plague was prevalent, doctors rushed around to treat patients and control the epidemic. Wizards and gods feel that doctors have robbed them of their business and constantly harassed them. The doctor had to cover his face with gauze to prevent the wizard from recognizing him and taking revenge. The mask of Japanese ninja looks more delicate and wrapped more tightly. The purpose of these people has nothing to do with today's health cause, but it is comparable to today's stars: people can't recognize it.

When did the mask hook up with hygiene?

It was not until 1275 that people once again saw the figure of "mask" in Historical Records.

According to Kyle Polo, a famous traveler, "In the palaces of the Yuan Dynasty, people who offered food covered their mouths and noses with silk to let them catch their breath and not touch the food."

That cloth is not simple. After all, it belongs to Tianjia. Simple mask cloth made of silk and gold thread. I didn't expect Kyle Poirot's Essay to be recognized as a model for China people to invent masks.

But when you think about it, it's not reliable. One is that Kyle Poirot has never been to China, and scholars are still arguing. Second, covering your face with a cloth does not mean that it is a mask. In order to avoid smelling some irritating smells or spitting to pollute food, people everywhere can easily think of covering their faces, which is not technically difficult in itself.

In this way, the Persians are actually the ancestors of well-documented masks. After all, in the relief on the door of the Persian tomb, the priests all wore "masks".

Black Death and the First Generation of Medical Masks

There have been many large-scale infectious diseases in human history, and we in China have also given infectious diseases a proper term-plague. But all the year round, human beings have no concept of plague, even how to avoid infection. It was not until the Black Death, a malignant infectious disease, broke out in Europe in the Middle Ages that people came up with the concept of epidemic prevention and invented the first generation of medical masks.

When Mongolian troops attacked Kafa City (now Feo Docia in Crimea), they threw the bodies infected with plague into the city with a trebuchet, which led to the outbreak of the Black Death in Kafa.

Then, with Kafa's communication with people from all over Europe, the Black Death was introduced to Europe along the Mediterranean Sea, which eventually led to the outbreak of the Black Death in Europe.

How terrible is this plague?

Since the Black Death invaded Europe in the middle of14th century, 75 million to 200 million Europeans have died. Due to different statistical methods and bases, there are various accounts of the number of people who died of the Black Death in Europe. On the whole, 30%-60% of the population in Europe died of this deadly plague.

Thus, at the beginning of the17th century, French doctor Charles de Lome invented the first generation of medical masks and protective clothing.

At that time, the medical theory believed that the stench from the patients or victims of the Black Death spread the Black Death. In order to avoid infection, as long as you can't smell it. Of course, we now know that this statement is wrong, but in Europe at that time, this bird's beak mask was already the most advanced protective equipment.

With this medical mask, there is also a whole set of clothes. Black Death doctors usually wear a wide-brimmed fur hat, wrapped in canvas robes from neck to ankle, gloves on their hands and boots on their soles. Gloves, boots and masks are firmly embedded and sealed with wax. Wear it like a mask, and use it only after soaking it in aromatic substances.

This is the legendary first generation of medical masks.

The appearance and popularization of modern masks

The origin of serious modern masks is actually in Europe.

186 1 year, French scientist pasteur confirmed the existence of bacteria in the air through experiments. Pasteur pointed out that bacteria can infect people, so he invented a method of low-temperature sterilization, which is the famous "pasteurization".

Although scientists at that time had realized that bacteria could infect diseases, the route of transmission was not very clear, so doctors did not use masks to protect themselves during the operation, even though they wore surgical gowns and surgical caps. Doctors often infect patients' oral cavity and nasal cavity with bacteria during surgery, thus causing wound infection.

At this time, an epoch-making figure appeared, that is, German pathologist Ledek. Through research, Ledec found that air can spread bacteria, and then thought that droplets in people's conversation would lead to wound infection. Therefore, he suggested that doctors and nurses wear masks made of gauze to cover their mouth and nose during surgery. This is really effective, and the infection rate of patients' wounds is greatly reduced. Since then, doctors all over the world have followed suit.

The most primitive mask is just a layer of gauze wrapped around the nose, mouth and beard of the surgeon, which is tight and uncomfortable. 1897, a British surgeon installed a thin wire stent in the gauze to leave a gap between the gauze and the nose and mouth, thus overcoming the shortcomings of poor breathing and easy to get wet by saliva.

Two years later, a French doctor made a six-layer gauze mask, sewed it on the collar of a gown, and turned it over when using it.

Later, the mask was changed to a free system and hung on the ear with a ring belt. So the modern mask appeared.

Masks came out of the hospital and became a routine item for the public, followed by the most terrible infectious disease in history, "Spanish flu."

19 18 March 1 1 Before lunch, a soldier in Fenston Barracks, Kansas, USA felt fever, sore throat and headache, but the doctor thought he just had a common cold.

What the doctor didn't expect was that it was just the calm before the storm.

By noon, more than 100 soldiers had similar symptoms. A few days later, there were more than 500 "cold" patients in this military camp. Subsequently, the flu spread to Spain, killing a total of 8 million Spaniards. This flu was named "Spanish flu".

From March of 19 18 to the end of 19 19, about 20% people in the world were infected with "Spanish influenza". The estimated death toll in the world is about 20 million (the latest research estimate is about 654.38 billion+0 billion), which is more than the death toll in the First World War, which has also become one of the reasons for the early end of the First World War, because all countries have no extra troops to fight.

A large area of crops in northern India has not been harvested; Potatoes in Poland rot in the ground; Large copper mines in Africa and South America stopped mining; Trains between Germany and Sweden and between Portugal and Spain were interrupted; Because too many members are ill, the New Zealand Parliament is temporarily adjourned.

These are just the tip of the iceberg in a series of consequences caused by influenza.

Therefore, during the spread of the epidemic, people were forced to wear masks, especially the Red Cross and other medical personnel.

Looking back at history, masks allow us to build a wall between ourselves and the world, giving us a sense of security, and at the same time, secretly surging an atmosphere of fear.

But in any case, this time in novel coronavirus, we will finally win. The moment you take off the mask, all the regrets in winter will be resolved by the gentleness of spring.
