An enterprise in Huangpu District, Guangzhou City, developed a "microporous membrane protective mask" using the new black technology, a new nanomaterial microporous membrane technology. The reporter learned that this mask is mainly developed by using new nano materials and microporous membrane technology. The material is extremely stable, waterproof, breathable, and resistant to high temperatures. The effective protection time can reach more than 8 hours, which breaks through the 4-hour use period of global disposable masks and fills the international gap.
Due to the use of special materials, its comfort is significantly better than other disposable masks; the secret is that the middle layer of the mask is embedded with a PTFE nanofiber microporous composite membrane, which has a filtration performance of more than 95 microns for fine particles with a diameter of 0.3 microns % (That is, KN95 mask protection level is reached). The new crown pneumonia pathogen virus is transmitted through droplets, and the diameter of the droplet particles is generally about 5 microns. Therefore, the "Vije Microporous Membrane Technology Protective Mask" can filter the virus very effectively.
At the same time, the reporter learned through the relevant person in charge of the enterprise that when the manufacturer entrusts the sample to the third-party testing center for testing, the manufacturer is required to refer to the highest testing standard for testing. A number of test results show that a number of technical indicators of the microporous membrane protective mask far exceed the standard of medical protection level.
Ye Jingxi, head of R & D Fang Weijie's big health, said that the original intention of the development of microporous protective masks was to break through the following aspects: first, to improve the effective protection time of the masks; second, to shorten the production cycle of masks; The fourth is to reduce the cost of use; the fifth is to reduce waste recycling and solve environmental problems. Based on the above considerations, Vijda Health selected new black technology materials and new nano-material microporous membrane technology. Although the cost has increased, the above problems have been effectively solved.
The reporter learned that both the microporous membrane protective mask and the medical protective mask are three layers of protection. The only difference is that the middle filter layer of Viger's large health mask uses microporous membrane material, while the medical protective mask uses meltblown cloth. . The microporous membrane protective mask has good air permeability and strong waterproof performance. Even if it is worn for a long time, the mouth will not have obvious discomfort. Good materials create good quality. The filtration efficiency of this microporous membrane mask is significantly better than that of conventional disposable masks. Although the surface price will be higher than that of single-use medical masks, the cost will be greatly reduced.
