Shanghai Wo Yi filter cotton

Shanghai Wo Yi purification filter cotton using aramid (Aromatic polyamide,) synthetic fiber made from non-fabric Recessed, low wind resistance, good air permeability, stable performance and chemical resistance. Stable performance, long-term use of high temperature of 220 ℃ without aging, and excellent dimensional stability, heat shrink at 250 ℃ was only 1%, short-term exposure to 300 ℃ high school will not shrink, crisp, softening or melting, and only began to decompose at 370 ° C above about 400 ℃, carbide.

Good flame retardant properties of synthetic high temperature filter cotton, no spontaneous combustion, not combustion, self-extinguishing nature, fire insoluble droplets, to produce a small amount of smoke, natural carbonation, from glass fiber breakage, out fiber, and other phenomena.
Shanghai Wo Yi purification filter cotton purposes:

Widely used in chemical plants, thermal power plants, carbon black plants, cement plants, lime plants, coking plants, smelters, asphalt plant, painting plant, and electric arc furnaces, oil boilers, incinerators flue and hot air filter, both effective dust removal, but also resistant to chemical erosion of the harmful smoke, filter tar, soot, dust and other particles produced in the high-temperature drying room to prevent the destruction of the goods the quality of surface paint.
