The core product of the existing mask is fused anger cloth, fused anger cloth is a better product in the existing mask, and the existing mask can not replace the lacking product only, and the mask is a veneering product and is not easy to be too thick, the mask is required to be thin, soft and fit to the face, the three elements of the mask are 1, virus is blocked, 2, ventilation is ensured, 3, the shape is fit, but the three elements are mutually restricted, the anti-virus mask has the advantages that the anti-virus mask is contradictory and contradictory, and is difficult to be adjusted to be uniform, so that the mask is worn, particularly in a severe case and a high-risk area of an emergency room, the risk of the mask is very high, the virus is parasitic on polluted water vapor or atmospheric powder or saliva and enters a human body, and the fact that the virus enters the human body is known, so that a better product is needed to be known to prevent the virus from invading the human body, and the fact that the important layer of fused anger cloth can completely prevent the virus from invading is avoided.

At present, the problems of not tight sealing exist in the better masks, namely N100, N95 and N90 masks which are only grade requirements of technical indexes of blocking and shielding virus indexes and air permeability on the front of the masks and can only be used as general low-grade protection, theoretically, the virus invasion can not be effectively blocked in practice in the better masks, because the four sides of the masks can not be sealed well enough, people who are too dead can not breathe normally to suffocate and die due to too much sealing, the larger the impression of the face skin is, the higher the skin-breaking infection probability is, the direct peripheral gap virus penetration inlet and outlet can exist in normal breathing, the better the mask material is, the tighter the human breathing is, the worse the mask material is, the higher the possibility of virus invasion on the front of the mask is, the good and bad of the peripheral gap virus invasion of the material are in a pair contradiction, no reconciliation is possible. The mask, the cap, the goggles and the front eye shield in the protective clothing set cannot achieve an excellent face protection effect, so that the discomfort caused by wearing a set of armed clothes is not known, particularly, the long wearing time is difficult, the pain caused by skin breaking is increased for the long time of the face mask, the breathing is extremely difficult, the long-time work cannot be eaten and drunk, the important factor that physical strength is excessive and the body is uncomfortable is caused by piecing together, the wearing is not good, the risk of direct virus infection caused by imprecise sealing is still very high, and the fact that no mask ensures a totally-closed product to effectively protect against viruses and a totally-closed protective clothing product is used for effectively protecting against viruses.
