Description
Technical field
The present invention relates to filter cloth production technical field, specifically a kind of superhigh molecular weight polyethylene fibers filter cloth.
Background technology
With scientific and technological progress, industrial expansion, press filtration, filtering machine equipment widely using among industry, also drive
Various filter clothes are more extensive in the industrial production to be used.Industrial filter cloth is the mistake formed by natural fiber and synthetic fibers weaving
Filter medium, is mainly used for separation of solid and liquid and gas solid separation.Synthetic fibers mainly have polypropylene fibre, terylene, polyamide fibre, polyvinyl etc., wherein with
Terylene and polypropylene fibre are the most commonly used, and based on separation of solid and liquid, the industrial filter cloth of broad sense also includes various metal material mesh grids such as
Stainless steel wire, nickel wire, brass wire.Can have now with the industry of filter cloth：Medical manufacture, chemical industry, open a mine, food processing with
Manufacture, metallurgical smelting, ceramic manufacture, cement etc., filter plant, separation equipment, press apparatus, filter press in these industries
Deng filter cloth is that these equipment are indispensable.Weaving filter cloth is the filter cloth that kind is most, purposes is most wide.
At present in country's chemical fiber, polypropylene（PP）, polyester (PET) and polyamide（Nylon PA）Should in filter cloth of weaving
With the most extensive.（1）, polypropylene fibre filter cloth：Have stronger acidproof (organic and inorganic), caustic corrosion ability and elasticity, it
Maximum 140-160 DEG C of temperature in use, maximum fusing point are：165-173 DEG C, extension at break：18 ~ 35%, price is low, but cloth is strong
Degree is weaker, is filtered for fibrous type filter pulp and coarse crystal.Polypropylene cloth surface is smooth, soft texture, and slag dumping performance is good;Density
It is low, can acid and alkali resistance and strong oxidizer corrosion and speck effect.But dimethylbenzene can be dissolved in, in tetrachloroethane solvent, hygroscopicity is low,
Below 0.3%, pigment is commonly used in, on dye filtering.（2）, polyamide（Nylon）Fiber filter cloth：Polyamide（Nylon）Filter cloth has
There are preferable tensile strength and abrasion performance.Intensity during moistening is 80% -90% of intensity when drying, this is just influenced
The stability of filter cloth size, commonly uses temperature and is no more than 110 DEG C.Acid resistance is poor, and alkali resistance and resistance to other medicine performances are good.Except by
It is more stable in other solvents outside the influence of benzoic acid, formic acid and glacial acetic acid.Since the surface of the fiber is most smooth, and there is suction
It is moist, so easy cake discharge.At abroad, Japan nearly all uses nylon 6, and Great Britain and America then uses nylon66 fiber mostly, and the latter's is heat-resisting
Property is slightly better than the former.Polyamide（Nylon）The shortcomings that maximum of filter cloth is exactly unstable chemcial property, and easily releasing micro has
Evil material, carries out secondary pollution, so such filter cloth cannot be used for food processing, bio-pharmaceuticals etc. and enter human body to filtrate
Industry.（3）, polyester fiber filter cloth：Polyester fiber filter cloth intensity is high, has flexibility, and wearability is preferable, has superior particle to cut
Performance is stayed, chemical stability aspect energy acid corrosion-resistant, alkali resistance aspect is slightly worse, also there is high resistance to microbial action, gathers
Ester filter cloth various types, are widely used.
It is short in wear-resisting property, acid-proof alkaline, shock resistance and service life for three of the above chemical fibre filter cloth
Present on larger deficiency, it is an object of the invention to provide one kind to adapt to high filtration pressure, high squeeze pressure and high washing
Pressure, improves acid-proof alkaline, wear-resisting property, the superhigh molecular weight polyethylene fibers filter cloth for the performance and used life of resistance to tension.
The content of the invention
In order to reach object above, the technical solution adopted in the present invention is：The superhigh molecular weight polyethylene fibers filter cloth,
It is characterized in that：Interweaved by superhigh molecular weight polyethylene fibers warp and superhigh molecular weight polyethylene fibers weft and be made, superelevation
It is filter opening between molecular weight polyethylene fibre warps and superhigh molecular weight polyethylene fibers weft.
The superhigh molecular weight polyethylene fibers warp and superhigh molecular weight polyethylene fibers weft are using plain weave or tiltedly
Line braiding is made.
The superhigh molecular weight polyethylene fibers warp and superhigh molecular weight polyethylene fibers weft, using the equal molecule of number
Measure 100 ten thousand-500 ultrahigh molecular weight polyethylene into intensity be 10-50 g/d superhigh molecular weight polyethylene fibers.
The superhigh molecular weight polyethylene fibers, also referred to as high-strength high-modulus polyethylene fiber, are to use fusion method or frozen glue
Method production, the fusion method is also known as dry method, and the frozen glue method is also known as wet method.
The specification of the filter opening is 100-1000 mesh.
The production method of the superhigh molecular weight polyethylene fibers filter cloth, it is characterised in that：It comprises the following steps completion：
（1）, fiber twisting divide cylinder：According to required specification superhigh molecular weight polyethylene fibers, twist coefficient is set, is processed into requirement
Cylinder yarn, so that warping uses；（2）, warping：By creel and warping machine, yarn is unwind from a certain number of bobbins,
It is wound up into the length of process stipulation on warp beam；（3）, plug in reed of gaiting：Warp thread in warp beam is provided according to looming draft
And technique of gaiting, successively by drawing-in piece, heald and reed, to form shed open by shedding motion on loom, with weft yarn with
Certain organization rule interweaves with forming fabric；（4）, looming weaving：Upper loom carries out weaving processing；（5）Sizing：Purpose is to change
The heat endurance or mechanical strength of kind filter cloth；（6）, thermal finalization：The purpose of thermal finalization is gathered in eliminate in preceding working procedure
Fiber and fabric, avoid producing high-elastic modification, improve the stability of filter cloth size；（7）, cut：According to filter filter plate
Size, cut and suture corresponding filter cloth；（8）, use：In use, below 100 ° of filtration temperature, can be according to actual mistake
Filter requires, and multilayer superhigh molecular weight polyethylene fibers filter cloth is stacked, is fixed on filter and uses.
The beneficial effects of the present invention are：Precision is high, and load is strong, has good tensile property, service life is common
More than 3 times of chemical fibre, dry-hot shrinkage are less than 2%, improve acid-proof alkaline, wear-resisting property, resistance to tensile property and use
In the service life, expand the use scope of filter cloth, improve filter quality, reduces filtering cost.
