As we all know, filtration is mainly to remove unnecessary particulate matter to improve the accuracy of analysis. However, if an inappropriate filter is selected, it will not only fail to achieve the purpose, but will become a source of pollution. In order to avoid this problem, People generally choose polytetrafluoroethylene filter cartridge membrane.
The chemical resistance of different fibers varies and is often affected by various factors such as temperature and humidity.
In comparison, polytetrafluoroethylene fiber has excellent chemical resistance, but is more expensive.
Therefore, when selecting filter materials, it is necessary to grasp the main factors according to the chemical composition of the dust-containing gas, and select the appropriate material.
The polytetrafluoroethylene filter cartridge membrane has a microporous structure with staggered fibers, with a porosity of up to 80%~90%. After high-temperature heat setting treatment, the microporous structure is stable and can effectively 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, effectively removes dust accumulated on the surface.
ptfe membrane manufacturer specializes in the production of polytetrafluoroethylene filter cartridge membranes. It has a full set of advanced production equipment and technology, and also has an advanced clean room and an independent composite slitting workshop to ensure the production quality of ptfe membrane; The product materials are all imported raw materials, with high uniformity, stable performance, good air permeability, and the filtration efficiency can reach 99.999995%! It can basically meet the filtration efficiency grade requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
