The polytetrafluoro-ptfe sintered filter element is made of pure polytetrafluoro raw material, sintered at high temperature and high pressure, so the filter element has strong acid and alkali resistance, strong alkali ability, high strength and toughness of the filter element, and the filter element can be High temperature resistance up to 200 ℃, has the reputation of "the king of filter elements". PTFE filter element, the interface form adopts standard M20, 222 and 226 interface form, which can be interchanged with other filter elements. At the same time, it has a flat push and pressure plate interface, which is used for precise size and steam filtration, and can also be made into various types according to requirements. type of interface.
Performance of polytetrafluoro-ptfe sintered filter element
①Resistant to strong acid and alkali.
②The high temperature resistance of 200℃ can be sterilized by steam and filtered by steam.
③High porosity: The porosity of the general metal sintered filter element is below 30%, while the porosity of the PTFE sintered filter element is as high as 50% or more, so the same filtration area has a large fluid flow.
④Smooth outer surface: The outer surface of the filter element is as smooth as "wax", so impurities are not easy to hang on the surface of the filter element. At the same time, the outer surface has high filtration precision, the inner layer has low filtration precision, and impurities are not easy to embed into the filter element body. The filter element is easy to clean and thoroughly cleaned. , the cleaning effect is excellent, and the service life is long.
⑤High strength and toughness: With high strength and toughness, the filter element is not easy to break, which is an incomparable advantage of metal filter elements, which completely solves the problem of huge losses caused by "breaking" of the filter element, which is a headache for manufacturers.
⑥High filtration precision: The filtration precision of PTFE sintered filter element can be 0.3um or even below 0.1um, which is beyond the reach of ordinary metal filter elements. High filtration precision and high porosity enable the filter element to have better fluid flow under high filtration precision conditions, which is practical.
⑦No "threshing" phenomenon: the inner and outer surfaces of the PTFE sintered filter element are very smooth, and fully sintered under high temperature and high pressure, there will be no "threshing" phenomenon during use to pollute the fluid, so it is safe in the water and manufacturing industries. It is widely used in filtering.
⑧ Strong "ozone" resistance: fully sintered at high temperature and high pressure, the filter element has higher ozone resistance than the PTFE folded membrane. be widely used.
