A new generation of three-dimensional masks help fight bacteria
A new generation of three-dimensional masks help fight bacteria January 05, 2016 Source: Xinhuanet Recently, a newly developed biological protection filtration new material has achieved the effect of “starving and killing†by intercepting viruses and adopting biotechnology to achieve the effect of “blocking and killingâ€. Based on this new technology, the R&D team has developed a new generation. Civil three-dimensional four-proof mask helps to fight against cockroaches. It is reported that the research and development team from Beijing Huilang Biotechnology Co., Ltd. is mainly composed of the former scientific research personnel of the Academy of Military Medical Sciences and the General Hospital of the People's Liberation Army. It is a group of experts in immunology, pathogenic microbiology and cytology. The team focused on how to effectively protect against diseases caused by the virus, especially those caused by respiratory tracts, and conducted in-depth research and discussion on how to avoid large-scale infectious public health events such as SARS in the future. In response to the common characteristics of viruses, a broad-spectrum bio-protective filter material with a mechanism of retention and inactivation of viruses, allergens and bacteria has been successfully developed. On December 9, 2015, the test report on the virus rejection rate of bioprotective filter materials issued by the relevant state departments showed that under the test conditions, the difference between the virus retention rate of the sample group and the virus rejection rate of the non-woven group was >40%. The sample has a retention effect. According to the person in charge of the company's technical team, this bio-protective filter media is mainly composed of a scientific combination of viruses, allergens, bacteria-specific receptors or ligands with high affinity, and biological fluids that are harmless to the human body. And spraying the fiber layer of this liquid. Natural air is filtered through this fibrous layer to effectively adsorb and prevent viruses, allergens and bacteria from entering the human respiratory tract, and the anabolism of the trapped viruses and bacteria is blocked, and the intracellular lysosomal membrane of the virus and bacteria is broken. Autolysis and death. In general, it is to "starve" by changing the micro-environment on which viruses and bacteria depend. At present, the company's "bio-protective filter media and its application" technology has obtained national invention patents. The data show that the protection of viruses, allergens and bacteria in the countries of Europe and the United States is almost blocked or filtered by physical methods that control the pore size of the air filter material, without blocking or inactivating pathogenic microorganisms and allergens. The new material developed by the company, through bio-protection methods, helps to reduce the probability of morbidity, which is the biggest innovation of the new bio-protective filter material technology. According to the person in charge of the company, the application prospects of bio-protective filter materials are very broad. The fiber layer sprayed with this liquid can be used for civil, medical masks and protective clothing, air filtration or purification devices for household and public places, civil and medical bedding and curtains. The company's civilian three-dimensional four-proof mask developed based on this new technology can not only effectively filter out PM2.5 particles, but also help prevent bacteria and prevent allergens.
