What are the materials for liquid filter bags?
Polypropylene fiber (PP, PP PP): good abrasion resistance, high elastic recovery, is a kind of thermoplastic fiber, polypropylene felt is often used in pulse bag pulse filter bag and low temperature chemical pharmaceutical factory in smelting plant. Polypropylene precision range: 0.1--500 microns, the highest temperature 94 degrees.Polyester fiber (polyester, PE): polyester fiber with good performance at room temperature, is the main material in bag filter. It can withstand the operating temperature of 130 DEG C under dry conditions. It will harden at 130 DEG C; fade, brittle, and make the strength weaker.
PTFE (PTFE): PTFE is a neutral polymer compound with a unique molecular structure that is completely symmetrical structure. Special structure makes it have good thermal stability, chemical stability, insulation, lubricity, water resistance and so on. High temperature, wide temperature range, can be in 260 degrees Celsius (high temperature for a long time continuously, instant temperature can reach 280 DEG C; the chemical stability, corrosion resistance; good self lubrication, low friction coefficient, wear a small filter; the surface tension of PTFE film is very low, with good inadhesion and water repellent of.: stainless steel wire mesh surface filtering, with very low flow resistance. The filter materials are weaved, interlaced, twill and linen. Metal mesh filters are suitable for use in oil filters in hydraulic and lubricating systems, for rough filtration of high speed fluids, or for safe filtration of coolant.
Accuracy range: 1--300 microns.Nylon mesh (NMO): nylon mesh and nylon mesh, nylon mesh, nylon mesh, nylon 6 (PA6) is a single by the flexible rapier loom plain weaving, dyeing (if necessary), processing and heat setting. Made from synthetic fibers; of polyamides. Nylon wire mesh has a high strength, wear resistance, chemical resistance, water resistance and elasticity are better, because the silk diameter is even, smooth surface, so the ink pass is also excellent. Its disadvantage is that nylon wire mesh has greater tensile property. After a period of time, the tension of the screen is reduced, and the screen plate is relaxed and the accuracy is reduced. Therefore, it is not suitable for printed circuit boards with high dimensional accuracy.
