Ultra-high molecular weight polyethylene filter cloth and production method thereof

Abstract

The invention discloses ultra-high molecular weight polyethylene filter cloth and a production method thereof. The ultra-high molecular weight polyethylene filter cloth is manufactured by ultra-high molecular weight polyethylene warp yarns and ultra-high molecular weight polyethylene weft yarns by adopting a twilled weave method. According to the ultra-high molecular weight polyethylene filter cloth and the production method thereof, the precision is high; the load is strong; the tensile property is good; the service life of the ultra-high molecular weight polyethylene filter cloth is three times longer than filter cloth made of common chemical fibers; the dry heat shrinking percentage is lower than 2 percent; the acid and alkali resistance, the abrasion resistance and the tensile property are improved; the service life is prolonged; the application range of the filter cloth is broadened; the filter quality is improved; and the filter cost is reduced.

Description

[0001] Technical field [0002] The invention relates to the technical field of filter cloth production, in particular to an ultra-high molecular weight polyethylene filter cloth and a production method thereof. Background technique [0003] Currently used for solid-gas separation and solid-liquid separation, synthetic fabrics are organically woven and non-woven. Among them, the woven filter material, because of its high strength, can withstand greater pressure and tension, is mostly used in filter equipment such as plate and frame filter press, belt vacuum filtration, drum suction filtration and disc suction filtration. Of solid-liquid separation. The non-woven filter material, due to its deeper filter layer, can achieve higher filtration accuracy and better air permeability, but it is easy to cause clogging of the hollows. In terms of strength, although the base is used Cloth is a framework material to enhance its strength, but it still has a certain gap with woven filter ...

Problems solved by technology

The filter cloth of this kind of filter press not only requires high filtration precision, but also requires high filtration efficiency and high wear resistance. Currently, the filter cloth used in the working condition is mainly imported filter cloth, which is not only expensive, but also not very satisfactory in use effect.

[0005] For the working environment, we first used high-strength nylon monofilament filter cloth for design and weaving, but due to the high friction coefficient of the working environment, the service life of the filter cloth is very short, and the filter cloth was worn out in only about two days. Obviously, The strength of the filter cloth is not suitable for the working environment, and we have designed a variety of filter cloths with different organizational structures, but none of them have achieved the desired effect
