In the novel coronavirus of 2020, when referring to 2020 possible risks, we thought of trade friction, debt default, financial pressure, geopolitics and even local wars. But the first black swan came from nature. In 2020, it started with a new outbreak of coronavirus pneumonia that swept the whole country and spread all over the world.






The severity of the novel coronavirus pneumonia is believed that many people have learned a lot from various sources of information, and also know the terrible nature of the virus. The main reason for this epidemic is that the virus can spread with droplet saliva. In this battle, we can not do without the use of all kinds of anti epidemic products, including masks, medical respiratory masks, goggles, etc.






These products are made of non-woven fabric, plastic PVC, TPE, silicone rubber and so on. Silicone rubber includes high-temperature silicone rubber and room temperature silicone rubber, among which high-temperature silicone rubber has excellent properties such as good biocompatibility, no odor, non-toxic, high temperature resistance, good tear strength, good product mobility, easy processing, etc. It is widely used in these epidemic prevention products.






Mask






In the field of civil masks, mask manufacturers make high-temperature silicone rubber into nose clips and wrap them in non-woven materials, or with non-woven fabric and plastic PVC in the outer layer to directly form a sealing ring, or directly make them to replace filter box masks, or make them into mask headbands. The excellent biocompatibility of the material can make the part of the mask contacting the skin of human body not easy to cause allergic redness and swelling reaction when worn for a long time; its good sealing, extensibility and processing performance can make the shape of the mask easy to fit the face of human body, suitable for all kinds of face types, and effectively isolate saliva pollution; the filter box is directly fixed on the sealed silica gel mask, thus reducing The parts are replaced and the maintenance work is simplified; the good rebound and soft touch of silicone rubber can also reduce the ear and head discomfort when wearing the mask.
