Press filter liquid paohuajian should use what cloth
Glass fiber filter clothThe characteristics of a glass fiber cloth, glass fiber cloth, high mechanical strength, fracture strength generally above 1300N; low elongation, fracture of glass sewing extension rate of only 3%, made of bag size stability; good performance of temperature below 260 DEG C, can be used for a long time; good corrosion resistance, can be used in acid gas, alkali; smooth surface, good air permeability, poor resistance to torture.Surface treatment is the main process in the production of glass fiber cloth, the aim is to improve the heat resistance, abrasion resistance, resistance and corrosion resistance. The general approach has dipped yarn processing (called pre processing) and cloth processing (called postprocessing two), the leaching processing of dipping liquid yarn along the gap permeability to the yarn of each stock asked, coated evenly, but the cost is higher than the cloth.
The surface treatment technology of glass fiber fabric has experienced four generations.The first generation, silicone (silicone) treatment, after treatment, the filter material has lubricity, reduce the damage caused by bending, dust spalling improved;The second generation, silicone, PTFE resin treatment, so that the heat resistance of filter materials increased by 20~30 degrees;The third generation of silicone, PTFE, graphite treatment, heat treatment filter material can be used at 280 degrees of continuous use, bending resistance, abrasion resistance, alkali resistance, acid resistance is also improved;The fourth generation, based on special resins, has improved resistance to chemical decay and dust strippingB, glass fibre cloth glass fiber bulked yarn is the use of the glass fiber puffing process soft, slightly swollen, three-dimensional structure, so that the glass fiber cloth with long fiber high strength and short fibers.
The advantages of the two fluffy cloth in high temperature resistance, corrosion resistance, but also has good air permeability, high purification efficiency.C, glass fiber needle felt glass fiber needle felt is a kind of reasonable structure and excellent performance of the new type of high temperature filter material. It not only has the advantages of glass fiber fabric of high temperature resistance, corrosion resistance, dimensional stability, high strength, small elongation and contraction, and the tapetum showed a single fiber (fiber diameter less than 6um). The three-dimensional porous structure, high porosity (up to 80%), the gas filter is a kind of high temperature resistance, high speed and high efficiency pulse filter material.The filter cloth is suitable for high temperature smoke filtration of chemical industry, iron and steel, metallurgy, carbon black, cement, waste incineration and so on.
