Nowadays, there are many materials used as filter media, which usually require porous, stable physical and chemical properties, and heat resistance. and chemical corrosion resistance, and polytetrafluoroethylene high-temperature membrane can meet the above requirements.
The mesh fabric is woven into the looped yarns with interlining warp yarns and weft yarns, so that this type of filter material has the characteristics of woven and knitted filter materials. It has a structure similar to woven fabrics and has improved dimensional stability. It also makes the warp yarns , the weft yarn has no shrinkage caused by interweaving, and has good particle separation characteristics. Its filtration effect is far better than ordinary types of knitted fabrics, and this type of filter material has high production efficiency. Among them, the weft-knitted mesh fabric can be directly used as a filter material. Weaving in the required size and diameter saves the sewing process and is easy to operate;
Polytetrafluoroethylene high-temperature membrane has many superior properties and has a wide range of uses, but the linear expansion coefficient of ptfe is large, so in continuous It is prone to deformation under load; it has poor resilience, low bending and compression strength, and extremely high melt viscosity. The pore diameter can be between 0.1-10um, the thickness can be between 2-100um, and the porosity can reach 50%–80 %, as many as hundreds of millions of micropores per square centimeter. Therefore, it can be rinsed with water to restore its performance and be reused, greatly extending its service life and saving costs.
It is a polytetrafluoroethylene high-temperature membrane manufacturer integrating production, sales and customization. The company has advanced PTFE film production lines and composite production lines. The company’s products are widely used in various fields.
