PTFE microporous membrane composite fabric plays an important role in epidemic prevention
This is an unexpected new challenge and a sudden new test – on the occasion of the New Year of 2020, the new coronavirus pneumonia epidemic is approaching fiercely. Faced with the spread of the epidemic, protective equipment such as masks and protective clothing continues to be in short supply. When the supply of disposable consumables cannot keep up, reusable polytetrafluoroethylene microporous membrane composite fabrics with high filtration efficiency are playing an important role in epidemic protection. It played an important role.
PTFE microporous membrane has a unique microporous structure and has Waterproof, moisture-permeable, corrosion-resistant and many other advantages make it the most advantageous in protective and environmental applications. The PTFE microporous membrane composite fabric can resist the penetration of microorganisms, blood and disinfection products, can block viruses to the greatest extent, and can be reused after sterilization, reducing medical waste. Because the polytetrafluoroethylene microporous membrane composite fabric has higher breathability, its comfort is better than other fabrics.
When normal protection When the price of melt-blown cloth, the core filter material of masks, soars and the supply is tight, protective masks made of polytetrafluoroethylene microporous membrane composite fabric stand out. The melt-blown material of ordinary protective masks intercepts harmful substances based on the principle of electrostatic adsorption. As the use time increases or the temperature and humidity change, its filtration efficiency drops significantly. Masks made of polytetrafluoroethylene microporous membrane composite fabric are based on the principle of physical barrier. The filtration efficiency will not decrease due to moisture or with increasing use time, and the polytetrafluoroethylene microporous membrane is waterproof and breathable, and will not appear In the case of water vapor retention, the breathing resistance is small and it is more comfortable to wear. The main advantage is that it can be reused after disinfection. In special periods, it can do a good job to solve the public’s protection needs and reduce the pressure on the environment caused by a large number of discarded masks. contribute. After testing by the testing agency, the protective mask made of polytetrafluoroethylene microporous membrane composite fabric fully complies with the national standard GB2626-2006 “Respiratory Protective Equipment-Self-priming filtering anti-particulate respirator”, and the filtration efficiency can reach above KN95 level. PTFE microporous membrane composite fabric can replace melt-blown cloth to make masks.
Due to Jusi Vinyl fluoride microporous membrane composite fabric has the advantages of waterproof and breathable, and has been widely used in various types of special military uniforms, firefighting suits, cold-proof clothing in high-cold areas, cold-proof boots, etc. During the SARS period, protective clothing made of polytetrafluoroethylene composite fabrics was already used in Beijing Xiaotangshan Hospital and other hospitals. It can not only effectively block viruses, but can also be reused after sterilization. In developed countries, polytetrafluoroethylene composite fabrics are widely used in various types of medical clothing, and can be reused after washing, drying, and autoclaving. They have good protection against blood and viruses under natural and pressure conditions. Barrier performance, filtration efficiency is greater than 99%. In the protection of the new coronavirus epidemic, polytetrafluoroethylene microporous membrane composite fabric has been applied to protective clothing, highlighting its advantages of high filtration efficiency, comfortable wearing, and reusability. It is made of polytetrafluoroethylene microporous membrane composite fabric. Multi-functional protective clothing has the advantages of durable waterproof, antibacterial, antistatic, flame retardant, moisture permeability, etc. It can resist the penetration of microorganisms, is resistant to blood and disinfection products, and blocks viruses to the maximum extent. After testing, all indicators are in compliance with GB19082-2009 national standard. Currently, there is only one mandatory standard for medical protective clothing in my country: GB 19082-2009 “Technical Requirements for Medical Disposable Protective Clothing”. In response to epidemic prevention and control work, the State Food and Drug Administration approved the “Reusable Medical Protective Clothing” on March 10. 》 (Project number: N2020001-T-BJ) The medical device industry standard formulation and revision project has been approved urgently. This will be a major benefit for the application of polytetrafluoroethylene microporous membrane composite fabrics in medical protective clothing and fully demonstrates its reusability advantages. , polytetrafluoroethylene microporous membrane composite fabric has become a high-tech material for epidemic protection and escort.
