With the development of science and technology and the increasing maturity of production technology, my country has developed rapidly in three-layer and five-layer composite materials, and its application scope is becoming more and more extensive. Today we will learn about this material.
Woven filter materials are most commonly used among woven filter materials. In addition, there are knitted fabric filter materials, three-way fabric filter materials and braided fabric filter materials.
Woven fabric filter material is made of twisted warp and weft yarns interwoven with a loom.
Since the warp and weft yarns are twisted, the density of the yarn itself and the interweaving points are relatively high.
The filter material can almost only pass through the gaps between the longitude and latitude lines.
Generally, the porosity of woven filter materials is only 30 to 40%, and it is straight-through.
Compared with three-layer and five-layer composite materials, woven filter materials have better dimensional stability and are suitable for making large-diameter and long filter bags.
The use of woven filter materials can produce filter materials that have greater strength and can withstand greater pressure. They can easily form flat and smooth surfaces or thin and soft fabrics, which are beneficial to filter bag dust removal.
At the same time, it is easy to adjust the tightness of the fabric, and it can be made into a loose filter material or a highly dense filter material.
Suzhou New Material Technology Co., Ltd. is a fluorine material film manufacturer that integrates the research, development, production and sales of PTFE air filtration membranes, PTFE bubble point membranes, three-layer and five-layer composite materials, Teflon films and coated filter materials.
The PTFE filter membrane we made by mechanically stretching PTFE material can ensure the complete retention of bacteria and other impurities, and at the same time have a large flux.
The material is resistant to high temperatures, strong acids and alkali, and has wide chemical applicability. When used for gas filtration, it can achieve 100% retention of various phages, bacteria and particles above 0.02um.
