The pore size of the kn95 mask filter membrane is evenly distributed
One of the main ways of transmission of the new coronavirus is droplet transmission. Wearing a mask when going out has become a way for everyone to isolate the virus. There is a consensus to cut off the spread of the virus and it is also a necessary protective measure. So what kind of material is the core raw material for making a mask? The kn95 mask filter membrane is one of them.
The most protective function of KN95 and N95 protective masks is the filter layer. The filter layer is made of polypropylene melt-blown microfiber electret material. The outer surface of the mask has not been hydrophobically treated. , contact with water, alcohol, etc. during use will destroy the structure of the material, greatly reducing the filtration effect. What’s more, blood often contains bacteria, viruses, etc., and the application scenarios of hospitals determine that medical staff are highly likely to be exposed to the patient’s blood environment. Therefore, hydrophobic treatment on the surface of medical masks is essential. The probability of ordinary people coming into contact with alcohol or blood is very low. As long as the mask is replaced regularly, it will not cause any harm if the outside is not treated like this.
The kn95 mask filter membrane has small pore size (0.05~0.45μm), even distribution, and large porosity, while maintaining air circulation. Through physical screening, viruses and bacteria are blocked on the surface of the mask, and with the help of the super self-lubricating characteristics of the polytetrafluoroethylene material, every time you exhale, the particles attached to the surface of the mask will be pushed back to the environment. Remove it repeatedly, without relying on electrostatic adsorption, and truly achieve an effective protective effect.
Suzhou New Material Technology Co., Ltd. is a fluorine material film that integrates the research, development, production and sales of kn95 mask filter membranes, ptfe bubble point membranes, polytetrafluoroethylene films, Teflon films and coated filter materials. factory.
