Problems solved by technology

[0002] The invention of the present invention belongs to high-temperature filter materials for long-bag low-pressure pulse dust collectors and reverse-air dust collectors. The characteristics of glass fiber are high temperature resistance, corrosion resistance, strong tensile strength, weak points, poor flexibility, poor wear resistance, and poor folding resistance. The interweaving points of woven fabrics have large pores, and the precision of dust filtration is low, especially when the service life of the pulse dust collector is short

Abstract

The invention relates to the technical field of dust removal filtration, and relates to a production technology of an ultrafine glass fiber and polyimide fiber composite woven fabric. The production technology comprises the following steps: 1, plying and twisting glass fibers and polyimide fibers to form blended yarns; 2, carrying out beam-warping and heddle-threading processes on the blended yarns to form a warp beam for later use, mounting the warp beam on a high-speed rapier loom, and weaving the blended yarns to form a composite woven fabric filter material; 3, carrying out hot cleaning and setting on the composite woven fabric filter material by a warp electric furnace; 4, carrying out chemical impregnating agent impregnation on the hot-cleaned and set composite woven fabric filter material to achieve corrosion-resistant surface treatment; and 5, carrying out pre-drying and baking processes on after the chemical impregnating agent-impregnated composite woven fabric filter materialto achieve drying and chemical impregnating agent curing treatment. The composite woven fabric has a good ash removal effect and a long service life.

Description

technical field [0001] The invention relates to the technical field of dust removal and filtration, in particular to a production process of dust removal filter cloth. Background technique [0002] The invention of the present invention belongs to high-temperature filter materials for long-bag low-pressure pulse dust collectors and reverse-air dust collectors. The characteristics of glass fiber are high temperature resistance, corrosion resistance, strong tensile strength, weak points, poor flexibility, poor wear resistance, and poor folding resistance. The interweaving point of the woven fabric has large pores, and the precision of filtering dust is low, especially the service life of the pulse dust collector is short. Contents of the invention [0003] In order to solve the above problems, the present invention provides a production process of superfine glass fiber and polyimide fiber composite weaving, which improves the dust filtration accuracy, the efficiency of dust ...
