Material Features
Micron filter bags are used in various industrial applications for filtering liquids and gases based on their particle size. They come in different materials such as polyester, polypropylene, nylon, and other specialized materials depending on the filtration requirements.
- Polypropylene fiber (polypropylene, PP): Polypropylene has good wear resistance and high elastic recovery rate. It is an excellent thermoplastic fiber. Polypropylene felt is commonly used in low temperature pulse filter bags of smelting plants and pulse filter bags of chemical and pharmaceutical factories. in. Polypropylene precision range: 0.1–500 microns, the highest temperature is 94 degrees.
- Polyester fiber (polyester, PE): Special polyester fiber has good performance at room temperature and is the main filter material in bag filter. It can be subjected to an operating temperature of 130 ° C under dry conditions; it will harden when it is continuously operated above 130 ° C; it will fade; its brittleness will also weaken its strength. Accuracy range: 1-300 microns.
- PTFE (polytetrafluoroethylene): Polytetrafluoroethylene is a neutral polymer compound with a unique molecular structure, that is, a completely symmetrical structure. The special structure makes it have good thermal stability, chemical stability, insulation, lubricity, water resistance and the like. High temperature resistance, wide temperature range, 260 °C (long-term continuous use at high temperature, instantaneous temperature up to 280 °C; strong chemical stability, corrosion resistance; good self-lubrication, very low friction coefficient, low filtration wear; PTFE The surface tension of the film is very low, with good non-stickiness and water repellency
- Nylon mesh (NMO): Nylon mesh, also known as nylon mesh, nylon mesh, nylon mesh, is made of nylon 6 (PA6) monofilament by flexible rapier loom weaving, dyeing (if needed), heat Formed and processed. Made of chemical synthetic fibers, it belongs to the polyamide system. Nylon mesh has high strength, wear resistance, chemical resistance, water resistance and elasticity. Because of the uniform wire diameter and smooth surface, the ink passability is also excellent. The disadvantage is that the nylon mesh has a large stretchability. The tension of the screen is reduced for a period of time after the wire is stretched, so that the screen printing plate is slack and the precision is lowered. Therefore, it is not suitable to print a circuit board or the like which requires a high dimensional accuracy.
