According to records, after the emergence of PTFE around 1979, the properties of membrane materials have been improved in all aspects, and many new products have been developed as a result, and PTFE base tape membrane is one of them.
As early as the mid-18th century, someone discovered the membrane phenomenon, but it was only in the past 50 years that the membrane process was actually applied to the industrial field.
In my country, the membrane industry started in the 1960s. After decades of development, PTFE baseband membrane technology has become an emerging and mature chemical separation technology.
Mature and developed technologies such as reverse osmosis, ultrafiltration, microfiltration, nanofiltration, electrodialysis, gas separation, inorganic membranes, pervaporation, membrane contact, membrane reaction and controlled release are being used in industrial production. , and produced good economic and social benefits.
The membrane separation process has become an important high-tech and sustainable development technology foundation for solving contemporary energy, resource and environmental pollution problems.
Among them, microfiltration is currently the most commonly used pressure-driven membrane technology with the largest sales volume. It is mainly used for the separation, purification, concentration and purification of particles, and is widely used in food, medicine, drinking water, Urban sewage treatment, etc.
The ptfe baseband 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 alkalis, 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.
