What are the types and materials of commonly used liquid filter bags?

Time: 2022-08-23

Liquid filter bag material

1. Polypropylene fiber (polypropylene, PP) Polypropylene has good wear resistance and high elastic recovery rate. It is an excellent thermoplastic fiber. Polypropylene felt is often used in low-temperature pulse filter bags in smelting plants and pulse filters in chemical and pharmaceutical factories. in the bag. Polypropylene accuracy range: 0.1-500μm, maximum temperature 94 degrees.

2. Polyester fiber (polyester, PE) Polyester fiber has good performance at room temperature and is the main filter material in bag filters. It can withstand the operating temperature of 130 ° C under dry conditions; continuous work above 130 ° C will harden; fade; become brittle, and the temperature will also weaken its strength. Accuracy range: 1-300μm.

3. Nylon mesh (NMO) Nylon mesh, also known as acrylic mesh, nylon mesh, nylon mesh, is made of nylon 6 (PA6) monofilament by plain weaving, dyeing, and heat-setting on a winding rapier loom. . It is made of chemical synthetic fibers and belongs to the polyamide series. Nylon wire mesh has high strength, good abrasion resistance, chemical resistance, water resistance and elasticity. Due to the uniform wire diameter and smooth surface, the ink passability is also excellent. When it is insufficient, the stretchability of the nylon mesh is large. The tension of this kind of screen is reduced for a period of time after the screen is stretched, which makes the screen printing plate slack and the accuracy decreases. Therefore, it is not suitable for printing circuit boards that require high dimensional accuracy.

4.PEFE (polytetrafluoroethylene) Polytetrafluoroethylene is a neutral polymer compound with a unique minute structure, that is, the structure is completely symmetrical. The special structure makes it have good thermal stability, chemical stability, insulation, lubricity, water resistance, etc. High temperature resistance, wide operating temperature range, long-term continuous use at 260 ℃ high temperature, instantaneous temperature up to 280 ℃; strong chemical stability, corrosion resistance; good self-lubrication, extremely low friction coefficient, small filter wear; PEFE film The surface tension is very low, with good non-stick and water repellency.
