Is it "try your best" or "brute force"? Can car companies make masks?

All this stems from a video I watched yesterday, called "Oriental Gods Beat Wall Street Leeks". When UP gave a lecture to Chongqing Beer, a famous cross-border enterprise, and cheated people by producing vaccines across banks, a barrage came: BYD also made masks. ...

I couldn't help chatting with this netizen for 300 rounds. Is it the same thing that BYD makes masks and Chongqing beer makes vaccines? Chongqing beer is used as a vaccine to cheat investors and investors, while BYD is used as a mask to cope with the epidemic and make some contributions. Then when I saw it, many people really questioned that car companies could make masks!

After statistics, I found that netizens mainly questioned these questions and analyzed them for you:

1. How do car companies that produce and assemble a pile of steel make masks?

The questioner is a friend of our editor, Mr. Pu. His question represents the thoughts of most netizens: how to make masks in automobile production lines?

First of all, explain to this friend's question that the "production line" of car companies really can't make masks directly, so how do you make masks?

First, if you want to make a mask, you need the following materials and equipment:

1. Raw materials: non-woven fabrics, meltblown fabrics, etc. The upstream raw material is polypropylene.

2. Fully automatic mask production line and skilled staff.

3. Sterile workshop.

Let's talk about it one by one:

First of all, raw materials, the following picture is a common medical mask, mainly composed of three layers of non-woven fabrics. The inner layer is ordinary non-woven fabric; The outer layer is waterproof non-woven fabric, which is mainly used to isolate the liquid sprayed by patients; The middle filter layer is made of polypropylene melt-blown nonwoven fabric treated by electret.

How did non-woven fabrics come from? It is necessary to drag the upstream raw material polypropylene particles and pile them up repeatedly to form non-woven fabrics.

The process of "stretching" is called spray melting. The fibers of the nonwoven fabric produced by this method are randomly and alternately arranged to form a more complex structure. With the subsequent electret treatment, the particles will be blocked.

So where do the non-woven fabrics and even polypropylene of car companies come from? The raw materials of SAIC-GM-Wuling, the first automobile company that claimed to manufacture masks, were provided by Guangxi Deford Group, which was its own supplier of sound insulation cotton.

Why use soundproof cotton? Because soundproof cotton is mainly composed of polypropylene and polyester fiber materials, the diameter of polypropylene fiber is controlled at? 2? The diameter of the wound is. 25? Hmm? On polyester fiber.

Therefore, polypropylene+spray melting only links masks with sound-proof cotton, giving SAIC-GM-Wuling and Guangxi Deford Group the first capital to produce masks.

So where did BYD's raw materials come from? People familiar with the matter said that BYD is its own supplier.

In addition, polypropylene is a product of the petroleum industry, and companies such as PetroChina and Sinopec have a lot of reserves to weave non-woven fabrics for you.

The second is the mask production line, which can be purchased or modified. At present, we know that the production line of SAIC-GM-Wuling is a joint supplier, which has been rapidly transformed with the strong support of Liuzhou government and even Guangxi and the state. Mandarin is like this:

"Will the original guangxi ford group? 2000? The square meter dust-free workshop was transformed into? 12? A mask production line, the daily output will probably reach by the end of the month? 170? Ten thousand. "

BYD, on the other hand, has its own Ninth Division, which can produce medical devices.

If you buy it, it is not very expensive. As long as the logistics is smooth, you can also buy a production line.

Among them, GAC is very hard-core and builds its own production line.

In terms of employees, Guangxi Telford Group has stepped up recruitment, while GAC is prepared to be self-reliant and send engineers to mask manufacturers to participate? 15? The days of study.

The third is the most critical part-clean workshop.

Dust-free workshop is the most difficult product to build or buy, but car companies have natural advantages in this respect: painting workshop is a standard dust-free workshop.

The mask production itself has a low technical content, and it is not difficult for car companies that have the ability to produce cars to produce masks in theory when the materials and equipment are complete.

To sum up, car companies can bring their own raw materials or obtain raw materials from suppliers, and the production line can also be modified or purchased. A dust-free workshop already exists. With the help of the government and the efforts of enterprises themselves, mask production can indeed be transformed.

Second, you can make masks at will?

Materials and equipment workshops can be ready, and car companies can rush to make masks and send them to the society? Of course not, just like new energy car companies have to get "birth certificates" (that is, "double qualifications" approved by the National Development and Reform Commission and the Ministry of Industry and Information Technology); Although the mask is small, it also needs its own "birth certificate"-medical device production license.

Domestic medical devices are divided into one, two and three categories, and medical protective articles such as masks and protective clothing belong to the second category. Enterprises that produce such articles need to obtain the permission of medical device manufacturers. In addition to enterprises, these products also need one-to-one medical device registration, and a registration number will be obtained after registration.

So how did SAIC-GM-Wuling get the "birth certificate"? It was strongly supported by the Party Committee and Government of Guangxi Autonomous Region and provided by China Development Bank? 5000? Ten thousand yuan loan, project approval and certification, etc.

BYD is better. The ninth division, which is responsible for mask production, has the qualification of medical device production.

To sum up, car companies, as large taxpayers and leading enterprises in various places, will probably be given the green light and quickly approved by the government in terms of qualifications if they intend to participate in mask production.

Last year, the national daily output was120,000. How dare you? 500? Wan?

I found the tiger pouncing on my brother and questioned: Last year's national Nissan? 1200? Wan, how dare you be a Nissan? 500? Wan?

Let's take a look at the production capacity of the mask production line: A few days ago, the official micro @ Gong Xinwei newspaper of the Ministry of Industry and Information Technology forwarded a CCTV interview with Liu Jingzhen, the chairman of China Pharmaceutical Group. It says that the production speed of masks in China is already very fast, just need? 0.5? Seconds/only.

In addition, before the domestic Nissan? 1200? Ten thousand, because the demand is so small, the upstream chemical enterprises produce polypropylene according to the annual fixed demand, and the middle non-woven enterprises order it as needed; It is naturally impossible for mask manufacturers to predict the epidemic situation in advance and store non-woven fabrics in the warehouse in advance.

In this epidemic, according to kevin huang, spokesperson of the Ministry of Industry and Information Technology and director of the Bureau of Operation Monitoring and Coordination, who is there? 2? Month? 2? China mask production capacity is about every day? 2000? Ten thousand, the capacity recovery rate at that time? 60%? Above, at this time, BYD, SAIC-GM-Wuling and other "transformation" enterprises have not joined.

4. Where are all these masks? Can we ordinary people buy it?

It is reported that the first batch of masks produced by SAIC-GM-Wuling will be handed over to the higher authorities for unified deployment. These masks will be mainly used for civilian use, and medical masks will be produced in the later stage.

The first batch of masks and disinfectant produced by BYD will be donated to specific groups such as buses, taxis, online car drivers and volunteers, and will be supplied to the market at low prices. What is the minimum order quantity of BYD masks circulating on the Internet? 1? Ten thousand, and only accept the public, but later BYD said it was false news.

Judging from the current situation, the first batch of off-line masks are likely to be allocated or given priority by the government, just like Wuling.

5. Why can't I buy a mask now?

Then why can't I buy a mask with such a large production capacity? Mainly due to the following reasons:

1.？ Raw material enterprises and mask manufacturers cannot predict the epidemic situation in advance and have not hoarded a large number of goods.

2.？ When the epidemic broke out, it was the Lunar New Year in China, the workers all went home and the logistics stopped. In addition, the blind closure of roads at the beginning of the epidemic led to insufficient manpower and limited transportation of raw materials.

3.？ It happens that this city, which is known as the "non-woven capital" of China, happens to be in Xiantao, Hubei.

4.？ Most importantly, medical masks need to be disinfected with ethylene oxide and then left to stand? 7- 15? Jesus Christ.

According to @ Gong Xin Weibo, medical masks are disinfected with ethylene oxide. After disinfection, there will be ethylene oxide residue on the mask, which will not only stimulate the respiratory tract, but also produce carcinogens. Residual ethylene oxide must be released by analytical methods to reach the safety content standard, and can only be released after passing the test.

That is to say, if from? 1? Month? 25? On the first day of the lunar new year, major enterprises will recall their employees to catch up with their work, and they will also be there? 2? Month? 10? I couldn't sit still until around 10, and with the logistics time and priority supply, it was really difficult for ordinary people to get it.

To tell the truth, during the epidemic, we car media people can't really do anything except produce some content to make everyone at home less bored. Therefore, I am also happy to answer your question about "Can car companies make masks in the end?". Can speak for the national conscience enterprises and answer friends' doubts. People also think that our influence on this epidemic is negligible.

This article comes from car home, the author of the car manufacturer, and does not represent car home's position.
