According to different application environments and functions, medical protective clothing has different standard levels for liquid and bacterial penetration, and the materials used are also different. PTFE protective clothing filter membrane is one of them.
Polypropylene spunbond fabric can be treated with antibacterial and antistatic treatments to make antibacterial protective clothing, antistatic protective clothing, etc.
Compared with traditional cotton protective clothing, polypropylene spunbond protective clothing is undoubtedly a big improvement.
Because of its low price and one-time use, it can greatly reduce the cross-infection rate. It has been widely promoted abroad for a long time after its launch.
However, the material’s resistance to hydrostatic pressure is relatively low, and its virus particle blocking efficiency is also relatively poor. It can only be used as ordinary protective equipment such as sterile surgical gowns and sterile wraps.
The porosity of the ptfe protective clothing filter membrane can reach 80%~90%, and has been processed by high-temperature heat setting. The micropore structure is stable and can effectively intercept dust particles. Moreover, its pore size is small and uniform, and the surface filtration mechanism makes dust removal easy. , has strong hydrophobicity and low surface energy, which can ensure the complete interception of impurities such as bacteria and has a large flux.
The material is resistant to high temperatures, strong acids and alkali, and has wide chemical applicability. When used for gas filtration, it can achieve 100% retention of various phages, bacteria and particles above 0.02um.
