Problems solved by technology

[0003] The above three filter materials have their own advantages and disadvantages: the paper filter material has high stiffness and mechanical folding yield, and can be used alone to make a folded filter element
[0004] Due to the poor folding yield of the synthetic fiber composite layer in the processing of the filter element, the filter element must be folded by heat setting, which has the disadvantages of complex processing equipment, low production efficiency, difficult processing, and low yield.

example 1

[0031] The plant fiber, synthetic fiber and glass fiber are respectively subjected to hydraulic dispersion and beating by a drum type hydraulic pulper under the condition of a pulp concentration of 1%, and the beating time is 8 minutes. After beating, mix according to the ratio of 20 parts of plant fiber, 10 parts of synthetic fiber and 70 parts of glass fiber, and mix it through a pulping machine to form a 2% concentration, which is now a mixture with water. At the same time, add 0.01% defoamer, 0.02% Dispersant, 0.2% compound antibacterial agent, to the slurry storage tank for slurry storage. After the mixed pulp is punched, it is sent to the headbox to be formed on the net, and the five dehydration zones of the wire part are dehydrated sequentially and gradually to keep the long fibers uniformly formed to form a fiber layer. Add 15% reinforcing adhesive to the wire part to strengthen, form and dehydrate through the wire part to form a wet paper tire with a dryness of 28%. T...

[0034] The plant fiber, synthetic fiber and glass fiber are respectively subjected to hydraulic dispersion and beating by a drum type hydraulic pulper under the condition of a pulp concentration of 1%, and the beating time is 8 minutes. After beating, mix according to the ratio of 30 parts of plant fiber, 5 parts of synthetic fiber and 65 parts of glass fiber, and mix it through a pulping machine to form a 2% concentration, which is now a mixture with water. At the same time, add 0.01% defoamer, 0.02% Dispersant, 0.2% compound antibacterial agent, to the slurry storage tank for slurry storage. After the mixed pulp is punched, it is sent to the headbox to be formed on the net, and at the same time, 3% composite flame retardant is added, and the five dehydration zones of the wire section are dehydrated sequentially in a gradient to keep the long fibers uniformly formed to form a fiber layer. Add 15% reinforcing adhesive to the wire part to strengthen, form and dehydrate through ...

Abstract

The invention discloses a composite filter material for a heat-setting-free pleated filter cartridge and a processing method of the composite filter material. The composite filter material is prepared by taking paper made of plant fibers, synthetic fibers and glass fibers as a base material, and compounding the base material and a polypropylene (PP) or polytetrafluoroethylene (PTFE) synthetic fiber filter film by adopting hot melt adhesive, liquid glue or an ultrasonic composite method. The paper made of the plant fibers, synthetic fiber materials and glass fibers serves as the base material, and the prepared material is a novel composite filter material which is low in airflow resistance, high in tensile strength, diversified in varieties, convenient to fold, wide in application range and excellent in overall performance.

Description

technical field [0001] The invention belongs to the field of filter materials, and more specifically relates to a composite filter material for a non-heat-setting pleated filter element and a processing method thereof. Background technique [0002] At present, most of the filter materials on the market are made of paper made of glass fiber or plant fiber, non-woven fabrics and membrane materials, which are used for air freshener filter elements, vehicle filter elements, boiler smoke filters and liquid filtration, etc. . Paper filter materials are made of different types of fibers, made of base paper by papermaking methods, and then strengthened to make filter materials with certain strength, easy folding processing, and different air permeability and pore size. Non-woven filter materials are processed into non-woven fabrics from synthetic polymer materials by non-woven processes, such as acupuncture, spunbond, melt-blown, etc., and then processed into non-woven filter mater...
