Abstract
The invention discloses a method for producing a composite filter material and relates to the technical field of environment-friendly treatment, in particular to filtration. In the method, the composite filter material is formed by forming two surface layers on two sides of a middle layer and by needling felt formation as well as singeing, calendering and thermoforming; and the middle layer is a glass fiber loom fabric, and the surface layers are formed by mixing an acrylic fiber, a Polyphenylene Sulfite (PPS) fiber and a polyester fiber and lapping. A nonwoven fabric formed by the method has the characteristic of high surface flatness, can fully separate gas from solid of the filter material, and has the advantages of high wear resistance, bending resistance and acid and alkali chemical resistance and long service life.
Description
Technical field
The present invention relates to environmental protection treatment, particularly filtration art.
Background technology
When control atmosphere pollution, ultrafine dust etc. is poisonous in order to collect, during pernicious gas, need a large amount of filtration equipments.
Filtrate in the filtration equipment on the existing market can only use in 130 ℃～150 ℃ working environments, and the life-span is short, and corrosion resistance is poor, substitutes cost height, too waste as adopting high-temperature filter material.
Summary of the invention
The object of the invention be to invent a kind of can high temperature resistant, corrosion resistant composite filtering material.
The present invention becomes felt with the auxilliary both sides that are located at the intermediate layer of two superficial layers through acupuncture, again through singe, press polish, thermal finalization form; Described intermediate layer is a glass fiber loom cloth, and described superficial layer is formed by acrylic fiber, PPS fiber and polyster fibre lapping after mixing.
The nonwoven that the present invention forms has the high characteristics of surface flatness, and the gas-solid of filtrate is separated fully, has wearability height, bend resistance height, antiacid, advantage that property height, long service life are learned in alkalization.
The specific embodiment
Operating procedure:
1, base cloth: becoming grammes per square metre with the woven appearance of pure glass fiber yarn warp-knit cloth is 400g/m
2Glass fiber loom cloth, stand-by.
2, shredding
1000kg terylene, 150kg acrylic fiber and 150kg PPS fiber are mixed, place and evenly mix shredding in the opener, stand-by.
3, combing
Acrylic fiber after the shredding, PPS fiber and polyster fibre are handled through carded, combing machine, formed and mix stratum reticulare.
4, lapping
The mixing stratum reticulare is laid on two outsides of glass fiber loom cloth respectively.
5, become felt
Pre-thorn is carried out in lapping earlier, carried out main thorn again, make the semi-finished product felt.
6, with the semi-finished product felt through singe, press polish, at last again through thermal finalization, form the composite filtering material nonwoven at last.
7, as required, the composite filtering material nonwoven is cut, make block composite filtering material.
Claims (1)
1. the production method of a composite filtering material is characterized in that the auxilliary both sides that are located at the intermediate layer of two superficial layers are become felt through acupuncture, again through singe, press polish, thermal finalization form; Described intermediate layer is a glass fiber loom cloth, and described superficial layer is formed by acrylic fiber, PPS fiber and polyster fibre lapping after mixing.
