We all know that when filtering, a suitable microporosity membrane must be selected according to the physical and chemical properties of the filtered medium before use. There are many kinds of materials for microporous filter membranes, and their properties are different. Here What the editor introduces to you is ptfe composite filter paper.
The melt-blown nonwoven fabric preparation process is a direct web-forming technology that uses the traction of high-temperature and high-speed hot air to prepare ultra-fine fibers. Compared with other nonwoven processes, the fiber diameter of meltblown nonwovens can reach 1-2μm, and the arrangement is randomly distributed and has a certain degree of chaos. This structure gives it a large specific surface area and porosity. Very high, with large dust holding capacity and good depth filtration performance.
ptfe composite filter paperThe product is made of polytetrafluoroethylene and is expanded and stretched to form a microporous film. This film is coated on the On various fabrics and substrates, it becomes a new filter material. The porosity can reach more than 88% or even higher, and this membrane has 1.4 billion micropores per square centimeter, with a pore size range of 0.1um-0.5um. The high-efficiency filter paper has high and low temperature resistance (-200℃-260℃ ), no aging, no splitting, no discoloration, and strong weather resistance after long-term use.
The ptfe composite filter paper produced by the manufacturer uses imported raw materials, has a full set of advanced production equipment, an advanced clean room and an independent composite slitting workshop. The production quality of the PTFE film is ensured; production and testing instruments imported from the United States are used to test the quality of the PTFE film, and it has also passed international SGS testing and certification, as well as ISI testing and certification.
