Micro-Glass fiber Composite Filter Paper

Glass fiber composite filter paper is made from ultra-fine glass fibers as raw materials using a wet process. It is formed by combining ultra-fine glass fiber paper with non-woven fabric. The composite non-woven fabric serves the purpose of protecting the core material of the glass fiber paper, and it can be applied on one or both sides. The product is characterized by high dirt-holding capacity, low resistance, high strength, and stable performance.

Working principle:

Because of  the nanoscale fineness of the ultra-fine glass fibers, the fibers are fused with impregnated cellulose and polyester resin, forming a paper-like mesh with a micro-porous structure. When the liquid to be treated passes through the surface non-woven fabric and reaches the ultra-fine glass fiber paper, impurities and nanoscale particles in the liquid are trapped by the non-woven fabric layer and the network-like structure of the ultra-fine glass fibers, resulting in a clean liquid product.

Application

Ultra-fine glass fiber composite filter paper is mainly used for the filtration of high-grade aviation oil, hydraulic oil, heavy oil, water in nuclear power plants, compressor oil, and other liquids. It effectively removes impurities from the liquid, resulting in purified liquid.
