In recent years, as the purification engineering industry has begun to focus on two-way acceptance standards for product quality and stability, clean room high-efficiency filtration membranes have made outstanding contributions to some high-level purification environments.
The 100-level clean room is the most commonly used and therefore the most important dust-free workshop. This clean room is widely used in the manufacture of implanted items in the body, surgeries, including transplant surgeries, the manufacture of integrators, and those that require special structures. : Isolation treatment for patients who are particularly sensitive to infection of capsules, flagella, and fimbriae, such as isolation treatment after bone marrow transplantation in patients.
The clean room high-efficiency filtration membrane is suitable for various clean rooms from level 1 to level 100,000. It adopts a special processing technology and is a microporous film made by calendering, extrusion, biaxial stretching and other methods.
This kind of membrane has excellent breathability, corrosion resistance, aging resistance, high temperature resistance and other properties.
According to the usage requirements, the pore diameter can be between 0.1-10um, the thickness can be between 2-100um, the porosity can reach 50%–80%, and there are up to hundreds of millions of micropores per square centimeter.
The clean room high-efficiency filtration membrane is prepared using a unique biaxial stretching technology, which can ensure complete retention of bacteria and other impurities while having 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.
PTFE microporous membrane has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency air filters.
