Abstract
The invention discloses ultra-high molecular weight polyethylene filter cloth and a production method thereof. The ultra-high molecular weight polyethylene filter cloth is manufactured by ultra-high molecular weight polyethylene warp yarns and ultra-high molecular weight polyethylene weft yarns by adopting a twilled weave method. According to the ultra-high molecular weight polyethylene filter cloth and the production method thereof, the precision is high; the load is strong; the tensile property is good; the service life of the ultra-high molecular weight polyethylene filter cloth is three times longer than filter cloth made of common chemical fibers; the dry heat shrinking percentage is lower than 2 percent; the acid and alkali resistance, the abrasion resistance and the tensile property are improved; the service life is prolonged; the application range of the filter cloth is broadened; the filter quality is improved; and the filter cost is reduced.
Description
Technical field
The present invention relates to the filter cloth production technical field, a kind of specifically ultra-high molecular weight polyethylene filter cloth and production method thereof.
Background technology
The fine fabric that closes that is used for solid and gas separation and Separation of Solid and Liquid at present has woven and nonwoven two big classes.Wherein woven filtering material because it has higher intensity, can bear bigger pressure and pulling force, so be used for plate compression, the belt vacuum suction filter is in the Separation of Solid and Liquid of filter plants such as rotary drum suction strainer and disc type suction strainer more.And the nonwoven filter material because it has darker filtration aspect, both can reach higher filtering accuracy; Gas permeability preferably can be arranged again; But causing the empty obstruction of thread easily, aspect powerful, is that framework material is to strengthen its powerful measure though adopted base cloth; But a certain distance is arranged, so be used in the solid and gases separation such as flue gas ash removal, rare metal Powder Recovery with woven filtering material more.No matter woven and nonwoven filter material; With regard to filter effect, should comprise heatproof; The performance of acid and alkali-resistance, filtering accuracy, filter effect and service life aspects content; No matter but which kind of industry, which kind of working condition of which kind of technical process, its first element raw material mix to filtering material is to use, and adopts reasonable raw material structure, weaving method and suitable count could guarantee that filtering material in use obtains the effect of being satisfied with and have only.
The pressing filter that existing work condition environment is relatively harsh is mainly used in rare metal operating modes such as gold, and pressure filtration is to utilize pressure that pressurized equipment provides as motive force, Gu make suspension realize a kind of filter process of liquid-separation.This kind canvas press cloth had both required filtering accuracy high, requires filter efficiency again, and the intensity of high abrasion will be arranged, and operating mode uses filter cloth to be mainly the import filter cloth at present, not only cost an arm and a leg, and result of use neither be felt quite pleased.
To work condition environment, we adopted the filter cloth design of high-strength nylon monofilament to weave before this, but because the coefficient of friction of work condition environment is high; Filter cloth is very short service life; Only about two days, filter cloth is just galled, obviously; Filter cloth intensity and work condition environment are unsuitable, and the filter cloth that we have designed multiple different tissues structure does not again all reach ideal effect.On the type selecting and result of use of filter cloth repeatedly, we sum up, and only find the sufficiently high raw material of a kind of brute force, could design the filter cloth that is fit to operating mode according to property of raw material.We find a kind of raw material of supra polymer finally through carrying out many inquiries exploration, and we at first consider in design, the problem of filtering accuracy; This kind raw material is a kind of novel material, and performance is fine, and we find the raw material mix of multifilament; Though the multifilament filtering accuracy is good, consider the filter effect of industrial and mineral, we are through research; Adopt the raw material of many yarn counts, cross in the city, strengthen the twist of multifilament what multifilament was twisted; Make multifilament after the twisting approach the state of monofilament, in the filter cloth of design, can keep filtering accuracy like this, can improve filter effect again.In fabric tissue, select 2/2 twill-weave for use, because the intertwined point is rarer relatively, so filter opening is bigger; But the multifilament structure raw material that this filter cloth adopts, relative aperture is more, two kinds of methods selected complementary effect for use; Neither influence the rate of filtration, do not influence filtering accuracy again.
Summary of the invention
The object of the present invention is to provide a kind of high filtering pressure, high squeeze pressure and height of adapting to wash pressure, improve acid-proof alkaline, anti-wear performance, anti-tensile property and the ultra-high molecular weight polyethylene filter cloth in service life.
In order to reach above purpose, the technical scheme that the present invention adopted is: this ultra-high molecular weight polyethylene filter cloth is characterized in that: adopt twill weave to process by ultra-high molecular weight polyethylene warp thread and ultra-high molecular weight polyethylene weft yarn.
Described twill weave is to adopt 2/2 twill weave.
The density of described ultra-high molecular weight polyethylene warp thread is 472-354/10 ㎝.
The density of described ultra-high molecular weight polyethylene weft yarn is 177-118/10 ㎝.
The production method of this ultra-high molecular weight polyethylene filter cloth is characterized in that: it may further comprise the steps completion:
(1), produces the ultra-high molecular weight polyethylene warp thread: with superhigh molecular weight polyethylene fibers multifilament twist yarn, winder;
(2), produce the ultra-high molecular weight polyethylene weft yarn: with superhigh molecular weight polyethylene fibers multifilament twist yarn, winder, warping, gait;
(3), warping: adopt GA169 type high-speed warping machine that ultra-high molecular weight polyethylene warp thread and ultra-high molecular weight polyethylene weft yarn are carried out warping;
(4), looming weaving: loom adopts the happy GTX rapier loom of Bi Jia, loom speed: 320 rev/mins;
(5), washing: adopt WR-1400 normal temperature and pressure autojig to clean, the washing solvent burden ratio is a water: degreaser: alkali=90:5:5; Temperature: 90 ℃; Running speed: 10m/min; Wash cloth: 3 roads;
(6), typing: setting temperature: material softening point temperature; Typing speed: 8m/ branch; Chilling temperature: be lower than the material vitrification point.
Beneficial effect of the present invention is: precision is high, and load is strong, has good tensile property; Be more than 3 times of ordinary chemical fiber service life; Dry-hot shrinkage has improved acid-proof alkaline, anti-wear performance, anti-tensile property and service life less than 2%, has enlarged the scope of application of filter cloth; Improve filter quality, reduced the filtration cost.
