Abstract
The present invention provides a method for producing a plate-type filter cloth, which has the technical scheme that the plate-type filter cloth is formed from at least two layers of nonwoven chemical fiber clothes and a layer of yarn net which are coated by adhesive between every two layers and combined and dried by heating. Products produced by the present invention have the advantages of high strength, high temperature resistance, corrosion resistance, proper air permeability, favorable filter effect, etc., and can be widely applied to the industries of petroleum, chemical industry, brewing, pharmacy, beverages, filtering treatment for environmental protection, etc.
Description
The invention belongs to and use chemical fiber non-woven fabric to manufacture the production method of filtering material, particularly a kind of production method of manufacturing plate-type filter cloth with chemical fiber non-woven fabric.
Existing filtering material mainly contain filter paper, cotton, needle punched blanket, hair, the braid of absorbent cotton, terylene (polypropylene fibre) fiber etc.These filtering materials exist that intensity is low, non-refractory, not corrosion-resistant, problems such as filter effect is bad, the accumulated slag that sticks together with filter medium in independent use.Make the multiple filtration plate if select for use different materials in these filtering materials to be combined with each other, its complex manufacturing, cost costliness, and operation inconvenience in use, change frequent, waste is very big.
The objective of the invention is in order to provide a kind of and existing multiple filtration board production technology to compare production method with plate-type filter cloth simple, with low cost, the plate-type filter cloth of producing with the present invention should be able to reach the intensity height, high temperature resistant, corrosion-resistant, Air permenbility suitable, the requirement of good filtration effect.
Technical solution of the present invention is to make plate-type filter cloth after being at least between each layer of two layers chemical fiber non-woven fabric and one deck gauze coated with adhesive and, drying compound through heating.
Above-mentioned said chemical fiber non-woven fabric is meant terylene non-woven fabric or nonwoven polypropylene fabric.
Above-mentioned said gauze is meant fibrous braid or wire braid.
Above-mentioned said adhesive is meant acrylic acid polyester or polyethylene powder class adhesive.
Above-mentioned said heating combined temp is 80 ℃～200 ℃, and optimum temperature is 100 ℃～160 ℃, and heating recombination time is 5 seconds～60 seconds, and Best Times is 15 seconds～40 seconds.
Above-mentioned said baking temperature is 60 ℃～150 ℃, and optimum temperature is 80 ℃～130 ℃, and be 8 minutes～20 minutes drying time, and Best Times is 10 minutes～15 minutes.
Optional two～eight layers of the number of plies of above-mentioned said chemical fiber non-woven fabric.Optional 0.5mm～the 1.5mm of every layer thickness.Adhesive should be coated between each layer of chemical fiber non-woven fabric equably with gluing machine.Heating the compound thermal composite machine that adopts carries out.Drying can adopt drying channel to carry out.
Industries such as the plate-type filter cloth of producing with the present invention can be used for oil, chemical industry, brewages, pharmacy, beverage, the processing of environmental purification sewage water filtration.
The present invention compared with prior art, have advantages such as simple and easy to do, with low cost, the product that adopts the present invention to produce have intensity height (specification is that 30 * 5cm fracture strength is 240 kilograms), can high temperature resistant (reaching 110 ℃), acid-alkali-corrosive-resisting, that pressure falls is suitable, suitable (21 liters/m of Air permenbility
2Second), good filtration effect advantages such as (the filtrate granularity are less than 30 μ).
The inventor once implemented the present invention.Long 2 meters of choosing, wide 1 meter, thick is three of the terylene non-woven fabrics of 1mm, long 2 meters of choosing, wide 1 meter, one of terylene gauze, (Dalian, Liaoning Province package packing machine factory makes with gluing machine, 1.2 meters of specifications) acrylic acid polyester adhesive is coated in equably the surface of terylene non-woven fabric and terylene gauze, and terylene non-woven fabric and terylene gauze be combined with each other, again terylene non-woven fabric after compound and terylene gauze are sent into thermal composite machine (Dalian, Liaoning Province package packing machine factory manufacturing, 1.2 meters * φ of specification 300mm) heating is compound, heating-up temperature is 160 ℃, the hot-rolling linear velocity is 0.5 meter/minute, to heat filter cloth after compound at last and put into the drying channel after dry 10 minutes that is connected with hot blast, promptly finish the production process of plate-type filter cloth, hot blast temperature in the drying channel is 100 ℃, and the plate-type filter cloth made from said method can be used for acrylic factory filtration acrylic liquid.
Claims (4)
1, the production method of plate-type filter cloth, the invention is characterized between each layer of the chemical fiber non-woven fabric that will be at least two layers and one deck gauze coated with adhesive and under 80 ℃-200 ℃ temperature, heat compound, it heats recombination time is 5 seconds-60 seconds, place then under 60 ℃ of-150 ℃ of temperature and carry out drying, be 8 minutes-20 minutes its drying time.
