Express! A single giant may officially produce masks!

February 25th: According to a person familiar with the matter, a giant silicone monomer company has purchased multiple mask production lines, cooperated with a downstream daily chemical company to produce it, began to assemble production equipment, and manufactured epidemic prevention products. A large number of orders have been obtained so far. !! These batches of mask production lines will fill the gap in the demand for medical masks from large and small enterprises in the silicone industry chain, and play a positive role in alleviating the shortage of epidemic prevention materials in the industry and resuming downstream work.


According to the information disclosed by the National Development and Reform Commission, as of February 22, China's daily output of masks has reached 54.77 million. In addition, the output of protective clothing and disinfectant solutions has also increased significantly, and small packaging services will be provided to be put on the market as soon as possible. Data show that in addition to Tibet, masks have been added to the production line of masks in 30 provinces, autonomous regions and municipalities. At the same time, new production lines are constantly being put into operation. As of February 22, China's daily output of masks reached 54.77 million, an increase of 2.8 times over that of February 1. The cumulative production of masks in the past 20 days was 570 million.
Medical protective masks refer to self-priming filtering dust-proof medical protective masks that can filter particles in the air and block droplets, blood, body fluids, secretions and so on. Common medical masks are mainly composed of three layers of non-woven fabric: the inner layer is ordinary non-woven fabric, the outer layer is non-woven fabric with waterproof treatment, and the middle filter layer is made of polypropylene melt-blown non-repellent polypropylene. Woven fabric-the core material of medical masks.
Production environment and requirements of medical masks
The production of medical masks requires a dust-free and sterile environment, and the workshop must meet the requirements of a 100,000-level purification workshop. According to the USA Federal Standard, the level of the purification plant is set by the number of dust particles ≥0.5 μm (micrometer) per cubic meter. The 100,000-level purification workshop has less than 100,000 fine particles of 0.5 μm (micrometer) in each cubic meter.
