The present invention relates to a kind of being applicable in industries such as mining, PETROLEUM PROCESSING, the oil under inflammable, the explosive environments, liquid filter the industrial filter cloth that is adopted, and especially take off the antistatic industrial filter cloth of using in the operation such as cured at the ketone benzene as oil.
At present, in inflammable, explosive operations such as mine coal washing, oil plant PETROLEUM PROCESSING, the most uses of used filter cloth is cotton sail filter cloth on its industrial filter, and some is the chemical fibre filter cloth.Cotton sail filter cloth in use, have the generation of being difficult for static charge accumulation, the advantage that safety coefficient is high, its range of application is extensive than chemical fibre filter cloth goods, but also because cotton sail filter cloth is poor at working strength and acid and alkali-resistance degree, cause its service life short, often cause the unplanned property stopping production of using producer, change the number of times height, directly cause renewal cost to increase, the a large amount of valuable solvent of loss also, contaminated environment, repeatedly stop production treat the worker loss from talking.And the lucky characteristic with cotton sail filter cloth of chemical fibre filter cloth forms a sharp contrast its intensity height, acid-alkali-corrosive-resisting, long service life; But itself characteristic is exactly very easily to produce a large amount of static charge accumulations in filter process, especially in overhaul of the equipments is changed, when it is peeled off filter nylon grid and produce electrostatic spark, volatilization solvent fuel gas in filter is fired, and safety coefficient is low.Therefore, it is stranded that the lesson of practice makes the use of fibers material filter cloth.
Goal of the invention of the present invention is to provide a kind of working strength height, and alkaline-resisting sour solvent corrosion particularly provides a kind of filter cloth for industrial use that has anti-static effect concurrently.
Another goal of the invention of the present invention is to provide a kind of filter cloth for industrial use of realizing filtering production efficiency height, good filtration effect on the purpose basis of stating in realization.
Filter cloth for industrial use of the present invention, its main technical schemes is: be woven into to filter with chemical synthetic fiber and antistatic yarn and use cloth, wherein antistatic yarn is to be plied to required common yarn by polyester staple fiber and stainless steel fibre blending.
In such scheme, for reaching the optimization ratio of antistatic and cost, both reached the static requirement of standard filter cloth, need meet cost requirement again, antistatic yarn is that the stainless steel fibre blending by 94～97% terylene short fiber peacekeeping 3～6% becomes required yarn.
In technique scheme, chemical synthetic fiber both can adopt the chemical synthesis long fibre, also can adopt various chemical synthesized short fibers in addition.
The filter cloth for industrial use that technical solution of the present invention provided has changed chemical fibre raw material and can not be used for traditional concept inflammable, explosive filtration art.Adopting the blending stainless steel metal fibre to weave forms, not only make full use of intensity height, acid-alkali-corrosive-resisting and the resistant to elevated temperatures advantage of chemical fibre, and by stainless steel fibre formation leakage path, electrostatic charge that will chemical fibre gathered in filtration work is released, simple chemical fibre filter cloth static index height, defective that safety coefficient is low have been avoided effectively, long service life has been saved a large amount of valuable solvents.This filter cloth for industrial use not only is suitable for inflammable, explosive oil, liquid filters applications, also is suitable for the application that dust takes off the dirt aspect.Eliminated the Electrostatic Absorption of chemical fibre filter cloth greatly, had the low characteristics of the dust quantity of sanction, promptly at the filter cloth inwall, when the dust that is filtered reaches certain dust-loaded thickness, can come off good permeability voluntarily, filterability is superior, can reduce the energy consumption that the mechanical oscillation pressure comes off effectively.In addition, adopt synthetic staple and antistatic yarn to weave the industrial filter cloth that forms, its surface forms one deck short fiber suede, and the gap of weaving cotton cloth is many and fine and closely woven than long fibre, and therefore except that having above-mentioned every advantage, this filter cloth also can make filter oil, liquid be easy to from a large amount of gaps pass through, the existence of short fiber suede increases exponentially the filter cloth and the contact area of oil, liquid, improved adhesive force greatly to cured body in the oil, good filtration effect, and production efficiency improves.
The weaving process of filter cloth for industrial use of the present invention is: conductive fiber that this filter cloth adopts requires it not only excellent conducting performance will be arranged, and will meet the requirement of strength of filter cloth itself, so adopts stainless steel fibre in the practical application.At first, stainless steel fibre is become antistatic yarn with the polyester staple fiber blending, generally reach 20 yarns and get final product.The blending proportioning of stainless steel fibre and polyester staple fiber is 3～6% stainless steel fibres, 94～97% polyester staple fibers.Then, twisted and plied with the synthetic chemistry fiber through twisting mill, the number of pooling capital can be decided according to the different needs of practical application, the filter cloth that is made into is applied in that ketone benzene takes off in the cured operation in the oil plant in the present embodiment, the chemical synthetic fiber that it adopts can be synthetic continuous fibre or short fiber, and its preferred plan is chemical synthesized short fibers, as polyester staple fiber, polyamide fibre short fiber, polypropylene short fiber etc., its plying number is generally 6 strands, and wherein one is an antistatic yarn; Take off in the dirt filtration application at dust, by chemical synthesis long fibre or synthetic staple and antistatic yarn plying, the plying number can be 4 strands, and wherein one is an antistatic yarn.Behind winder and warping process, enter to draw and combine and quilling again, be woven into cloth at last, its structure can be twills closely.In the operation of weaving cotton cloth, for reaching the electrostatic charge standard, keep certain cost requirement again, can only in unidirectional line, add and knit antistatic yarn, as in warp or parallel, by there being an anti-electric yarn to weave in 2～7 warps or in the parallel.
Be the experimental data table of comparisons of this filtration below with cloth and cotton sail filter cloth and chemical fibre filter cloth:
