[China Glass Net] The reasonable design of fiber multi-scale, multi-layer and dust collector, combined with the precise arrangement of microchannels, can effectively improve the comprehensive dust removal performance of fiber filter materials. 1, the performance of commonly used fiber filter materials 1) Needle felt made of asbestos fiber can withstand high temperatures of 350 ° C, but it is no longer used due to its carcinogenicity. 2) Metal fiber and high temperature resistant ceramic fiber as a filter material have superior performance, but the price is too expensive and is only used in special industries. 3) Glass fiber has unique properties, its strength, toughness and chemical resistance are good, its chemical properties are stable, it is non-hygroscopic, it does not swell, it can withstand high temperature of 260 °C, and it has good thermal stability. Under high temperature conditions Has a good filtration effect and no danger of fire. Like graphite fibers and silicon fibers that have been used for many years, glass fibers have high friction when woven and have a coating. Glass fiber does not burn, softens at 500 ° C ~ 700 ° C, and its chemical stability is good. By drawing the glass fiber, glass fibers of different diameters can be obtained, which can effectively remove particles of different micrometers. Glass fibers can be made into woven, mesh, mat, felt, filter paper, film and other forms of filter material. Each filter material has a high void ratio and a large dust holding space. 2, the choice of filter fabric Woven fabric filter materials can be divided into three categories: monofilament fabrics, multifilament fabrics, and spun yarn fabrics. The monofilament fabric can be made of a monofilament having a diameter of 0.003 mm to 3 mm, such as polyamide, polyester, polypropylene, polyvinyl chloride, polytetrachloroethylene, and Kevlar. The plain weave filter material may have a pore diameter of 5 μm to 25 μm; if the pore diameter is to be less than 5 μm, a twill fabric may be used; the satin will make the microchannel opening narrow. Woven filament fabrics are primarily used for wet filtration. The multifilament fabric has compressibility and thus can form a fabric having a small pore size, which fabric has a good intercepting effect on small particles. Multifilament plain and twill fabrics generally use thicker yarns to produce fabrics with higher endurance. Since the multifilament yarn has a larger contact surface with the dust layer, the dust removal effect is not as good as that of the monofilament fabric. The filter material made of spun yarn fabric has a good retention effect on the granules, and the inner space of the yarn and the fiber can filter, and the short-fiber plain and twill fabrics generally have a higher density. The main advantage of the spun yarn fabric as a filter material is that its surface is rough and hairy, and the surface of the fabric has a strong trapping effect on dust. The loose yarn structure allows the hairiness of the fiber surface to form an effective retention effect on particles of different magnitudes, and the hairy surface also contributes to the improvement of the permeability resistance. Common filter materials are: Metamax filter material, P84 (polyimide) filter needle felt, room temperature filter needle felt, composite needle felt, glass fiber bulk yarn filter cloth, glass fiber woven Cloth, fiberglass needle felt, etc. Polyester Yarn,Polyester Filament Yarn,Polyester Dty Yarn Fabric,Polyester Blended Yarn Shaoxing Shiffon Textile Co., Ltd , http://www.shiffontex.com
