Embodiment Construction

[0017] The embodiments of the present invention are described in detail below, and examples of the embodiments are attached. figure 1 with 2 Shown in. The embodiments described below with reference to the accompanying drawings are exemplary, and are only used to explain the present invention, and cannot be construed as limiting the present invention.

[0018] In the present invention, a high-temperature resistant fiber non-woven filter cloth based on monofilament woven mesh is provided. The filter cloth consists of a two-layer structure, namely: a base cloth layer 2 and a filter layer 4 (attached figure 1 in). The base fabric layer is a woven net structure made of chemical fiber monofilament materials with warp and weft interwoven. This kind of warp and weft interlaced woven mesh base cloth layer only plays the role of support and reinforcement, so the density of the warp and weft interlaced is as small as possible under the premise of ensuring the role of support and reinforceme...

Abstract

The invention discloses a method for manufacturing high-temperature-resistant filter cloth by using mineral fibers. The fiber monofilament is made of a woven net structure interwoven with warp and weft; the filter layer is a non-woven fabric structure formed by needle-punching basalt short fibers; then, the surface of the basalt short fiber layer is calendered. The invention not only has excellent high temperature resistance, but also solves the contradictions and problems of low filtration efficiency and easy deformation of a single woven filter cloth, and insufficient strength and easy damage of a single non-woven filter cloth.

Description

Technical field [0001] The invention relates to a filter cloth, in particular to a method for manufacturing a high temperature resistant filter cloth using mineral fibers. Background technique [0002] At present, industrial non-woven filter cloths are widely used in the filtering process of smelting, chemical industry, building materials, thermal power, waste incinerators, coal-fired boilers and other industries under high temperature and harsh working conditions. One of the common shortcomings of these filter cloths is not It can withstand the high temperature environment in the filter production process, resulting in a short service life of the filter cloth and an increase in production costs. Summary of the invention [0003] Based on the above technical problems, it is necessary to provide a filter cloth, which not only has the sturdy and durable performance of woven filter cloth, but also has the performance of withstanding high temperature and the high efficiency filtering ...
