Nowadays, there are many filter media on the market, each of which has its own advantages. PTFE liquid filtration membrane is one of many filter materials. Let’s take a look at the details.
Any porous material that can allow fluid to pass through and intercept solid particles contained in the fluid to achieve solid-liquid separation is collectively called a filter medium.
It is a key component of the filtration device, which determines the accuracy and efficiency of filtration.
There are many types of filter media, which are divided into three categories according to their structure: flexible media, rigid media and loose filter media.
Flexible filter media, rigid filter media and loose filter media.
Among them, ptfe liquid filtration membrane is a flexible filter medium. ptfe liquid filtration membrane is a neutral polymer compound with a unique molecular structure, that is, a completely symmetrical structure.
The special structure makes it have good thermal stability, chemical stability, insulation, lubricity, water resistance, etc.
High temperature resistance, wide operating temperature range, can be used continuously for a long time at 260℃ (high temperature, instantaneous temperature can reach 280℃); strong chemical stability, corrosion resistance; good self-lubricating, extremely low friction coefficient, very low filter wear Small; the surface tension of the PTFE membrane is very low and has good non-stickiness and water repellency.
The PTFE filter membrane produced by Suzhou PTFE filter membrane manufacturer by mechanically stretching PTFE material can ensure complete retention of impurities such as bacteria and has 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.
