Problems solved by technology

[0003] In the process of filter cloth manufacturing, it is necessary to sew a layer of edge layer on the outer layer of the filter cloth, and to apply a layer of sealant to seal the joint between the two, but most of the existing sealant materials are traditional rubber. The sealants made of these traditional rubbers are easy to degumming, but when the rubber is used, because the rubber surface is large, it is easy to foam and crack in a large area, which shortens the service life of the filter cloth, and the application between the rubber and the filter cloth It is not tight enough and the sealing is poor. Therefore, we propose a new research and development method for filter cloth and sealant

Abstract

The invention discloses novel sealant-coated filter cloth, comprising a filter screen body and sealing nets, wherein the sealing nets are arranged on the front face and the back face of the filter screen body, the filter screen body and the sealing nets are fixed in a hot-pressing compounding mode, and the connecting positions of the edge of the filter screen body and the sealing nets are sewn through sewing lines. According to the filter cloth, the filter cloth body and the sealing nets are connected through the sewing lines and a sealant, so connection is more stable, and the service life ofthe filter cloth is prolonged to a certain extent; the sealant is prepared from novel preparation raw materials; epoxy resin, plain weave carbon fibers, chinlon, polypropylene fibers and the like areused for manufacturing of the novel sealant-coated filter cloth; and by utilizing an outward pushing method and a rheological property test, the adhesion performance of the filter cloth body and thesealant is stronger, sealing performance is more stable, a service cycle is longer, large-area foaming between the sealant and the filter cloth body is avoided, and large-area sealant failure of a sealant surface is also avoided.

Description

technical field [0001] The invention relates to the technical field of filter cloth, in particular to a research, development and manufacturing method of a novel glued filter cloth and sealant. Background technique [0002] Filter cloth is a filter medium woven from natural fibers or synthetic fibers. Includes metal mesh or strainer. Mainly used in air filtration and dust removal, dust collection powder, to purify the air, protect the environment, in smelters, chemical plants, sugar, dyes, medicine, food and other industries. [0003] In the process of filter cloth manufacturing, it is necessary to sew a layer of edge layer on the outer layer of the filter cloth, and to apply a layer of sealant to seal the joint between the two, but most of the existing sealant materials are traditional rubber. The sealants made of these traditional rubbers are easy to degumming, but when the rubber is used, because the rubber surface is large, it is easy to foam and crack in a large area,...
