Abstract
The invention discloses a high-temperature resistant and acid-and-alkali resistant industrial filter cloth material. The high-temperature resistant and acid-and-alkali resistant industrial filter cloth material is prepared from the following raw materials in parts by weight: 30 to 60 parts of tetrafluoroethylene-hexafluoropropylene copolymer, 30 to 60 parts of polyphenylene sulfide, 20 to 30 partsof ethyl alcohol, 20 to 30 parts of distilled water ethanol, 10 to 15 parts of polyester, 1 to 5 parts of polytetrafluoroethylene powder, 1 to 3 parts of chromic oxide, 10 to 15 parts of polydiphenylterephthalate propane ester, and 1 to 5 parts of graphite powder. Besides specific advantages of a common filter cloth material, the industrial filter cloth prepared by the treatment process providedby the invention has very high wear resistance, very high cost performance, high resilience and good anti-static property; the cloth which is woven by doubling and twisting multi-strand yarns is dense, high in particle retaining property, and high in stripping property and air permeability. The series of products have the characteristics of acid resistance, alkali resistance, high strength, highfiltering capacity and the like; dust is extremely cleaned; the strength, the wear resistance and the water leakage property are excellent.
Description
technical field [0001] The invention belongs to the technical field of filter cloth production, and in particular relates to a high temperature resistant, acid and alkali resistant industrial filter cloth material. Background technique [0002] With the technological revolution and development of world industry, separation processes are widely used in chemical, petroleum, metallurgy, food, light industry, medicine, biochemical and atomic energy industries. Almost any modern industry is closely related to filtration to varying degrees. As a high separation, concentration, purification and purification technology, filter cloth filtration technology has been greatly developed in various fields. This separation technology has the advantages of simple operation, low energy consumption, small footprint, no secondary pollution, etc., and is especially widely used in water treatment. However, it is regrettable that these industrial filter cloths are limited by their own materials. ...
