Description
Technical field
The utility model relates to the filter cloth production technical field, a kind of specifically superhigh molecular weight polyethylene fibers filter cloth.
Background technology
Along with scientific and technological progress, industrial expansion, press filtration, filter equipment being widely used among industry also driven various filter clothes and in commercial production, used more widely.Industrial filter cloth is to weave the filter medium that forms by natural fabric and synthetic fiber, is mainly used in Separation of Solid and Liquid and gas-solid separation.Synthetic fiber mainly contain polypropylene fibre, terylene, and polyamide fibre, polyvinyl etc., wherein commonly used with terylene and polypropylene fibre, be main with Separation of Solid and Liquid, the industrial filter cloth of broad sense comprises that also various metal material mesh grids are such as stainless steel wire, nickel wire, brass wire.The industry that can use filter cloth now has: medical manufacturing, chemical industry, open a mine, food processing and manufacturing, metallurgically smelt, pottery manufacturing, cement etc.; Filter plant in these industries, separation equipment, press apparatus, filter press etc., filter cloth is that these equipment are indispensable.The weaving filter cloth is the filter cloth that kind is maximum, purposes is the widest.
In the present domestic chemical fiber, polypropylene (PP), polyester (PET) and polyamide (nylon PA) are used the most extensive in the weaving filter cloth.(1), polypropylene fibre filter cloth: stronger acidproof (organic and inorganic) arranged; Caustic corrosion ability and elasticity, 140-160 ℃ of its maximum serviceability temperatures, maximum fusing point is: 165-173 ℃; Extension at break: 18 ~ 35%; Price is low, but the intensity of cloth a little less than, be used for fibrous type filter pulp and coarse crystal and filter.Polypropylene cloth smooth surface, quality is soft, and the slag dumping performance is good; Density is low, can acid and alkali resistance and strong oxidizer corrosion and speck effect.But can be dissolved in xylene, in the tetrachloroethane solvent, hygroscopicity is low, below 0.3%, is commonly used in pigment, on the dye filtering.(2), polyamide (nylon) fiber filter cloth: polyamide (nylon) filter cloth has better tensile strength and abrasion performance.80%-90% of intensity when the intensity when moistening is dry, this has just had influence on the filter cloth size stability, and temperature commonly used is no more than 110 ℃.Acid resistance is poor, and alkali resistance and anti-other medicine performance are good.Except the influence that receives benzoic acid, formic acid and glacial acetic acid, more stable in other solvent.Because the surface of this fiber is the most smooth, and hygroscopicity is arranged, so unload cake easily.Abroad, Japan nearly all uses nylon 6, and the Great Britain and America then uses nylon 66 mostly, and the latter's heat resistance is better than the former slightly.The shortcoming of the maximum of polyamide (nylon) filter cloth is exactly a unstable chemcial property, emits the harmful substance of trace easily, and filtrate is carried out secondary pollution, so such filter cloth can not be used for the industry that food processing, bio-pharmaceuticals etc. get into human body.(3), polyester fiber filter cloth: polyester fiber filter cloth intensity is high, has flexiblely, and ABRASION RESISTANCE is better; Superior particle cutoff performance is arranged, chemical stability aspect ability acid corrosion-resistant, the alkali resistance aspect is poor slightly; Microbial action is also had high resistance, and the polyester cloth kind is a lot, is widely used.
