Background
At present, a disposable medical mask comprises a mask body, the mask body is generally made of face gauze or sanitary gauze materials, the thickness of the mask body is different according to different requirements, a common surgical mask is generally made of a PP non-woven fabric layer facing to the outside, a melt-blown fabric layer clamped between the PP non-woven fabric layer and the PP non-woven fabric layer contacting with the face of a person, the mask is also provided with more than three layers of multi-layer masks, but the basic principle of the mask is to utilize the PP non-woven fabric layer of the mask, in particular to a melt-blown cloth layer which is clamped in the middle and filters harmful germs or tiny drops containing viruses, taking melt-blown cloth as an example, the basic principle of the melt-blown cloth is that the plastic of polyethylene, after melting, the molten fiber is sprayed by hot air flow to form a great amount of fiber with the diameter of a few tenths of microns to dozens of microns, the filament winding layer is piled up on the substrate or the collecting roller to form a porous structure, and can adsorb and trap the germs and the droplet particles containing the viruses by the porous trap. Taking the example of a novel coronavirus, the virus particles are basically 60nm (zero to six microns) to several hundred nanometers (zero to several microns), and after the droplets are added, the virus particles can be adsorbed in a meltblown fabric winding layer or on an external PP non-woven fabric layer for protecting the meltblown fabric, and the filtered relatively clean air can enter the respiratory system of a person through the meltblown fabric layer. The existing masks have the problems that the cloth layers of the masks comprise melt-blown cloth layers, the main function is to block or adsorb pathogenic bacteria or droplets containing viruses, and the pathogenic bacteria or the droplets cannot be killed, the concentration of the accumulated harmful bacteria or the droplets containing the harmful viruses is higher and higher along with the accumulation of the filtration time, the accumulated harmful bacteria or the droplets containing the harmful viruses are more and more, the risk per se is higher and more, so the existing medical masks are short in service time and usually have to be replaced within 4 hours; for high-infectious viruses with unknown risks, such as novel coronavirus with an infection coefficient reaching 3.0-3.6 at present, the replacement speed of the mask can be higher, the mask replacement can be carried out once in 4 hours according to the production number of 2000 million masks in China counted by Ministry of industry and communications, 300 million mask replacement can be guaranteed, the mask replacement target is far away from the target of 14 million people in China called by a national expert group number, only 40% of capacity of the 2000 million masks is recovered at present, and the mask is recovered to 800 million every day, so that the mask containing the liquid drop virus can be sterilized or killed, the service time of the mask is prolonged, and the mask replacement method is very significant. Even if the mask is replaced once in 4 hours, the mask can be killed when the mask is contacted with germs or viruses due to the sterilization or virus dripping capability of the mask, so that the dangerous accumulation is avoided, and the safety of wearing the mask is improved.
