The polytetrafluoroethylene film produced by our factory(PTFE)The pleated filter element is made from pure imported polytetrafluoroethylene raw material through high-temperature and high-pressure sintering, thus this filter element has a very strong performance It has excellent acid and alkali resistance, strong alkali capacity, and the strength and toughness of the filter element are all very good. The interface form adopts the standardM20,215,220,222and226It has the same interface form and can be interchanged with other filter elements. It also has the flat push and pressure plate interfaces, which are used for precision size and steam filtration. It can also be made into various types of interfaces according to requirements.

Polytetrafluoroethylene film(PTFE)Performance of pleated filter elements

①Resistant to strong acids and strong alkalis.

②High-temperature resistant200℃ Steam and steam filtration can be used

③High porosity: For common metal sintered filter elements, the porosity is within30%The following is the porosity of the polytetrafluoroethylene sintered filter element "Gundam"50%Therefore, for the same filtration area, the fluid flow rate is greater.

④The outer surface is smooth: The outer surface of the filter element is as smooth as "waxed", so impurities are less likely to adhere to the surface of the filter element. At the same time, the filtration accuracy of the outer surface is high, while that of the inner layer is low, making it less likely for impurities to embed into the filter element body. The filter element is easy to clean and can be cleaned thoroughly, with excellent cleaning results, and thus has a long service life.

⑤High strength and toughness: The high strength and toughness make the filter element less prone to breakage. This is an advantage that metal filter elements cannot match, completely solving the problem of huge losses caused by the "breakage" of filter elements for manufacturers.

⑥High filtration accuracy: The filtration accuracy of the polytetrafluoroethylene sintered filter element can be achieved0.1umIt can really be achieved0.1umBelow, this is something that ordinary metal filter elements cannot achieve. The high filtration accuracy and high porosity enable the filter element to have a good fluid flow rate under the working condition of high filtration accuracy, which makes it practical.

⑦No "shedding" phenomenon: The inner and outer surfaces of the polytetrafluoroethylene sintered filter element are both very smooth, and it is fully sintered under high temperature and high pressure, so there will be no "shedding" phenomenon during use and it will not contaminate the fluid. Therefore, it is widely used in security filtration in the water production and pharmaceutical industries.

⑧Strong ozone resistance: The thorough sintering under high temperature and high pressure makes this filter element have a higher ozone resistance than the polytetrafluoroethylene folded membrane, and it is widely used in medicine, water production, and industrial "ozone" gas distribution and filtration
