Where is the threshold for the production of medical masks?

To produce masks that meet medical standards, it is necessary to have quality raw materials.

General civilian masks can be produced with only two layers of spunbond non-woven fabrics + filter layers, while medical masks and N95 masks need to replace the middle filter layer with melt-blown non-woven fabrics.

The melt-blown non-woven fabric itself has an electrostatic adsorption effect. With this layer of melt-blown non-woven fabric, the droplets and viruses in the air will be attracted by static electricity, and ordinary masks can be turned into "medical surgical masks" or "medical protective masks". ".

To produce this melt-blown non-woven fabric, melt-blown material is required, and melt-blown material is a chemical product that requires polypropylene synthesis.

The small workshop has no non-woven fabrics, and no meltblown materials. It can only use inferior fabrics or even pulp to make Sanwu fake masks. Although the output is large, the only use of the products may be to cover the faces of big stars.

On the other hand, medical masks belong to the second category of medical devices, and must be qualified for the production of medical devices. Although the country has opened the green channel for application in special periods, it is difficult for ordinary small factories to obtain the corresponding production qualifications.

The materials are exquisite, the qualifications are difficult to obtain, and the craftsmanship is not simple.

Disposable medical masks are divided into sterile and non-sterile types. At this time, of course, all that are needed are sterile. Medical surgical masks and medical protective masks are sterile by default.

Sterile masks must be produced in a clean workshop of no less than 100,000 grades. Building a clean dust-free workshop is a technical task. Even if there is a desire to build a dust-free workshop, it is difficult for companies without relevant experience to do it in half an hour.

After the medical masks are produced, they are also sterilized with ethylene oxide, but in this way, there will be ethylene oxide residues on the masks, which are harmful to the human body. The analysis process takes 7 days to half a month.

This is also the reason why the factory is now fully on fire, but the number of masks on the market does not seem to increase - we will not see the current production in 7 days at the earliest.
