Everything started yesterday when I watched a video called "Eastern Gods Strike Wall Street Leeks", in which the UP master spoke about the famous cross-border enterprise Chongqing Beer, cross-border production of vaccines to cheat people, floating over a line of pop-ups: BYD also do masks it ......
This I can't help but with this netizen on the line of three hundred rounds! The fact that BYD is making masks and Chongqing Beer is making vaccines is not the same thing, is it? Chongqing Beer to do vaccines that is to deceive investors and shareholders, BYD to do mask that is to deal with the epidemic, to make a contribution ah. I then took a look, there are really a lot of people questioned how car companies can do masks!
After statistics, I found that netizens mainly questioned these questions, to analyze one by one:
One, the production and assembly of a bunch of steel car companies, how to make the mask?
The questioner is our editor Mr. Pu's friend, his question represents the vast majority of netizens' ideas: how do automobile production lines make masks?
First of all, to explain the friend's question, the car company's "production line" really can not directly make masks, then how to make masks in the end?
First of all, if you want to build masks, you need the following materials and equipment:
1, raw materials: non-woven fabrics, meltblown cloth, etc., the upstream raw material is polypropylene.
2, mask automated production line and skilled staff.
3, Aseptic workshop.
We chat one by one:
First of all, the raw materials, the following picture is a common medical mask, mainly composed of three layers of non-woven fabric. The inner layer is ordinary nonwoven; the outer layer is a waterproof nonwoven, mainly used to isolate the patient's sprayed liquid; the filter layer in the middle is a polypropylene meltblown nonwoven with electret treatment.
Where does the nonwoven come from? The upstream raw material, polypropylene granules, needs to be drawn and repeatedly stacked to form the nonwoven fabric.
The "drawing" process, called meltblown, this method of production of nonwoven fabrics, fiber random and compartmentalized cross-arrangement, the formation of a more complex structure, with the subsequent resident pole treatment, particulate matter will be blocked.
So where does the car company's nonwoven fabric or even polypropylene come from? The first car company to claim to build a mask, SAIC-GM-Wuling, gets its raw materials from its own supplier of acoustic foam, Guangxi DeFord Group.
Why acoustic foam? Because the sound insulation cotton is mainly composed of polypropylene and polyester fiber material,? Through a special spray fusion filament technology to control the diameter of polypropylene fibers in 2 mm, and winding in the diameter of 25 mm polyester fibers.
So polypropylene + spray fusion, just the mask and sound insulation cotton linked together, so that SAIC-GM-Wuling and Guangxi DeFuTe Group has the first capital of the production of masks.
So where does BYD get its raw materials? According to people familiar with the matter, BYD is its own is its own supplier.
Also, polypropylene is a product of the petroleum industry, PetroChina, Sinopec and other companies have large reserves, and thoughtfully weave the nonwoven fabric for you.
The second is the mask production line, which can be purchased or remodeled. What we know so far is that SAIC-GM-Wuling's production line was jointly supplied and remodeled on the fly with strong support from the Liuzhou government and even Guangxi and the state. Here's what the official line says:
"The original ?2,000?square meter dust-free production workshop of Guangxi Deft Group will be converted into ?12?production lines for masks, and the daily output will probably reach ?1.7?million by the end of the month."
And BYD, itself, has a ninth division capable of producing medical devices.
It's not terribly expensive if you buy it, and it's OK to buy the production line as long as you make sure the logistics are smooth.
One of them, Guangzhou Automobile, is very hardcore and builds its own production line.
As for staff, Guangxi DeFord Group has stepped up recruitment, while Guangzhou Automobile is ready to stand on its own two feet, sending engineers to mask makers for a ?15?day study.
The third is the most critical part -- the clean room.
The clean room is arguably the most difficult product to build or buy, but car companies have a natural advantage in this area: the paint shop is a standard clean room.
The mask production itself is low-tech, with the ability to produce cars, car companies, in the case of materials, equipment, the production of masks is theoretically not difficult.
To summarize, car companies can provide their own or from suppliers to obtain raw materials, production lines can also be transformed or purchased, dust-free workshop would have been, in the government's help and the enterprise's own efforts, the transition to produce masks can indeed be done.
Two, casually produce masks?
Materials and equipment workshop can be ready, then the car companies can work feverishly to catch up with the mask and then sent to the community? Of course not, and new energy vehicle enterprises to get the "birth certificate" (i.e., the Development and Reform Commission and the Ministry of Industry and Information Technology approved the "dual qualification"); masks, although small, but also need their own "birth certificate"
Domestic medical devices, divided into I, II, III, masks, protective clothing and other medical protective supplies, belonging to the second class of medical devices, the production of such supplies, the enterprise needs to carry out the production of medical equipment license. In addition to the enterprise, these products also need to one-to-one medical device registration, registration will get a registration number.
So how did SAIC-GM-Wuling get its "birth certificate"? They received strong support from the Guangxi Autonomous Region Party Committee and government, with the China Development Bank providing a 50 million dollar loan and escorting the project all the way to approval and certification.
BYD is even more powerful, responsible for the production of masks of the ninth division, originally has a medical device production qualification.
To summarize, car companies as taxpayers and leading enterprises, if you want to participate in the production of masks, qualifications, the government will most likely give the green light, fast approval.
Three, last year, the country's daily production of 12 million, how dare you daily production of ?5? million?
I found a HuffPost old man questioned: last year the national daily production of ?12? million, how do you dare to daily production of ?5? million?
First, let's take a look at the production capacity of the mask production line: a few days ago, the official microblog of the Ministry of Industry and Information Technology @ Gongxin Weibao, forwarded a CCTV interview with Liu Jingzhen, chairman of the China National Pharmaceutical Group, which claimed that China's production of masks has been very fast, only needing ?0.5? seconds / only.
Also, before the domestic daily production of ?12? million, because the demand is so little, the most upstream chemical companies in accordance with the fixed annual demand for the production of polypropylene fibers, the middle of the non-woven fabric enterprises on demand order; mask manufacturers naturally is impossible to predict the epidemic, in advance of the hoarding of non-woven fabrics placed in the warehouse.
Meeting this epidemic outbreak, according to the Ministry of Industry spokesman, operation monitoring and coordination of the Bureau of Huang Libin had in ?2? month ?2? day, China's production capacity of masks is about 20 million per day, when the production capacity recovery rate of ?60%? Above, and this time BYD, SAIC-GM-Wuling and other "transition" enterprises have not yet joined.
Four, where are these masks? We ordinary people can buy?
It is reported that SAIC-GM-Wuling production of the first batch of masks will be handed over to the higher authorities for uniform deployment, the batch of masks will be mainly used for civilian purposes, followed by the production of medical masks.
The first batch of masks and disinfectant produced by BYD will be directed to donate to specific groups of people such as buses, cabs, online car drivers and volunteers, and will subsequently be supplied to the market at affordable prices. It was also rumored online that BYD's masks had a starting order of ?1?000 and would only be accepted for public-to-public transfers, but BYD later said this was untrue.
Based on the current situation, the first batch of masks coming off the production line will likely be government-deployed or prioritized to supply the front line, as in the case of Wuling.
V. Why can't I buy a mask now?
So why is the mask capacity so big, I still can't buy a mask? Mainly for the following reasons:
1.? Raw material companies, mask manufacturers are unlikely to predict the epidemic in advance, and not a large number of stockpiles.
2.? The epidemic happened just during the New Year's period, workers went home, logistics stopped, plus blind road closures around the country at the beginning of the epidemic, resulting in a shortage of manpower and limited transportation of raw materials.
3. The city known as the "capital of nonwovens" is located in Xiantao, Hubei Province.
4. Most importantly, medical masks need to be sterilized by ethylene oxide, and then need to be left to stand for?7-15?days.
According to @Industrial Microblogging, medical masks are sterilized with ethylene oxide, and after sterilization, there will be ethylene oxide residue on the mask, which not only irritates the respiratory tract, but also causes carcinogens. It must be resolved in such a way that the residual ethylene oxide is released to meet the safety content standards, and can only be shipped to the market after passing the test.
That is to say, if the first day of the year from ?1? month ?25? day, the major companies recalled employees to catch up with the work, but also to ?2? month ?10? day or so before the static finish, coupled with the logistics time and prioritize the supply of the first line of the situation, it is indeed difficult to the hands of the ordinary people.
■? State Review
To be honest, there's really not much we automotive media people can do during an outbreak, other than produce some content to make staying at home less boring for everyone. Therefore, I'm happy to answer your questions about whether car companies can make masks or not. To speak up for the national conscientious enterprises and answer your questions is a small part of our contribution to the epidemic.
