Problems solved by technology

At present, the filter cloth used at home and abroad cannot fully meet the requirements, and there are problems such as high moisture content of filter cake, low retention efficiency, and low continuous production efficiency. The main reasons for these problems are: 1) The retention accuracy of filter cloth is not enough, Material penetration is serious; 2) In order to meet the interception accuracy requirements of the filter cloth, the water permeability rate of the filter cloth is sacrificed

Embodiment Construction

[0028] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0029] see Figure 1~Figure 3 , is an electron microscope enlarged view of the front, back and sides of a filter cloth with 2 / 2 twill on the surface and double texture on the lower layer, which is applied to the high-purity extraction of nonferrous metals according to an embodiment of the present invention.

[0030] It is used in the filter cloth for high-purity extraction of non-ferrous metals. The multifilament of the filter cloth is made of ultra-fine denier porous polypropylene multifilament. It is any one of plain weave, twill weave, satin weave or all multi-layer fabric structures, and the high temperature range is 120~220°C.

[0031] Compared with the existing filter cloth made of ordinary polypropylene material, the fiber denier i...

Abstract

The invention discloses filter cloth applied to non-ferrous metal high-purity extraction. The multifilament of the filter cloth adopts superfine denier porous polypropylene multifilament, the filter cloth is manufactured in a high-temperature instantaneous polymerization surface treatment process after the weaving of warps and wefts, the texture of the filter cloth is plain, twill, satin weave or any one of all multilayer fabric structures, and the high temperature range is 120-220 DEG C. The filter cloth takes full advantages of the superfine denier porous polypropylene multifilament such as fine single fibers and porous single-beam multifilament, high-temperature instantaneous polymerization surface treatment process is adopted, and the woven filter cloth has the characteristics of high interception precision, good filter cake stripping capacity, excellent acid and alkali resistance and better hydrophobicity. Meanwhile, the invention discloses a weaving method of the filter cloth.

Description

technical field [0001] The invention relates to a filter cloth used for high-purity extraction of nonferrous metals and a weaving method thereof. Background technique [0002] Non-ferrous metals are essential basic materials and important strategic materials for national economy, people's daily life, national defense industry, scientific and technological development. Agricultural modernization, industrial modernization, national defense and scientific and technological modernization are inseparable from non-ferrous metals. For example, most of the components or components required for cutting-edge weapons such as aircraft, missiles, rockets, satellites, and nuclear submarines, as well as cutting-edge technologies such as atomic energy, television, communications, radar, and electronic computers are made of light metals and rare metals in non-ferrous metals; in addition, Without nickel, cobalt, tungsten, molybdenum, vanadium, niobium and other non-ferrous metals, there is n...
