Embodiment Construction

[0014] Refer to attached figure 1 Make the invention. The ultra-high molecular weight polyethylene fiber filter cloth is characterized in that: the ultra-high molecular weight polyethylene fiber warp 1 and the ultra-high molecular weight polyethylene fiber weft 2 are interwoven by a plain weave method, and the adjacent ultra-high molecular weight polyethylene fiber Between the warp 1 and the ultra-high molecular weight polyethylene fiber weft 2 is a filter hole 3 .

[0015] The warp 1 of the ultra-high molecular weight polyethylene fiber and the weft 2 of the ultra-high molecular weight polyethylene fiber can also be made by twill weaving.

[0016] The ultra-high molecular weight polyethylene fiber warp 1 and the ultra-high molecular weight polyethylene fiber weft 2 are made of ultra-high molecular weight polyethylene with a number average molecular weight of 1 million-500 and a strength of 10-50 g / d. Molecular weight polyethylene fibers.

[0017] The ultra-high molecular w...

Abstract

The invention discloses ultrahigh-molecular-weight polyethylene fiber filter cloth, which is characterized by being formed by weaving ultrahigh-molecular-weight polyethylene fiber warps and ultrahigh-molecular-weight polyethylene fiber wefts, wherein filtering holes are formed between the ultrahigh-molecular-weight polyethylene fiber warps and the ultrahigh-molecular-weight polyethylene fiber wefts. The ultrahigh-molecular-weight polyethylene fiber filter cloth has the advantages of high precision, high load, high tensile strength, service life of over 3 times that of normal chemical fiber, dry-hot shrinkage rate of less than 2 percent, improvement on the acid and alkali resistance, wear resistance and tensile strength, long service life, expansion in the using range of the filter cloth, improvement on the filtering quality and reduction in the filtering cost.

Description

technical field [0001] The invention relates to the technical field of filter cloth production, in particular to an ultra-high molecular weight polyethylene fiber filter cloth. Background technique [0002] With the advancement of science and technology, the development of industry, the widespread use of filter press and filter equipment in industry has also led to the wider use of various filter cloths in industrial production. Industrial filter cloth is a filter medium woven from natural fibers and synthetic fibers, and is mainly used for solid-liquid separation and gas-solid separation. Synthetic fibers mainly include polypropylene, polyester, nylon, vinylon, etc. Among them, polyester and polypropylene are the most commonly used, mainly for solid-liquid separation. The generalized industrial filter cloth also includes various metal materials such as stainless steel wire, nickel wire, brass Silk. The industries that can use filter cloth now include: pharmaceutical m...
