As we all know, the production of many products cannot be separated from a clean environment. Most of the various indoor places required for people’s lives, work, and social gatherings are relatively closed spaces. , due to the large flow of people and poor air mobility, these spaces are more likely to become high-risk places for the spread of viruses and bacteria, so they need to use air filters for filtration, and what plays a role here is the PTFE filter paper.
Polytetrafluoroethylene is a neutral polymer compound with a special molecular structure, that is, a completely symmetrical structure. The special structure makes it have good thermal stability, chemical stability, insulation, lubricity, water resistance, etc.
Temperature resistant, 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 ; It has good self-lubrication, extremely low friction coefficient, and very little filtration wear; the surface tension of the PTFE membrane is very low, and it has good non-stickiness and water repellency.
Polytetrafluoroethylene filter paper can achieve surface filtration. This is because the PTFE-coated filter material has a microporous structure and no through-holes on the surface, so dust cannot enter the interior or base of the membrane through the surface of the membrane. material, so that only gas passes through and dust or materials are trapped on the surface of the membrane. At present, this filter paper has been widely used in many fields such as industrial dust removal and precision filtration.
Polytetrafluoroethylene filter paper The manufacturer’s membrane material has a porosity of 80% to 90%, and has been heat-set at high temperatures. The microporous structure is stable and can well intercept dust particles, and its Small and uniform pore size, surface filtration mechanism, easy dust removal, strong hydrophobicity, low surface energy, good non-adhesive ability, good at removing dust accumulated on the surface, washing with water or backflushing can restore performance, greatly extending service life, filtration The efficiency can reach 99.999995%.
