Abstract
The invention discloses a production method of a compound filter material, relating to environmental-protection treatment, in particular to the technical field of filtering. The compound filter materials is produced by laying two surface layers on both sides of an intermediate layer, acupuncturing into a felt, and then singeing, calendaring and thermally forming, wherein the intermediate layer is a nomex fiber loom fabric, and the surface layers are formed by mixing acrylic fibers, PPS fibers and polyester fibers and the lapping. The non-woven fabric produced by the invention has the advantages of high surface smoothness, can ensure that gas and solid of the filter material are completely separated, and has the advantages of high abrasive resistance, bending resistance as well as acid and basic resistant chemical property, 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 Mei Tasi 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 is weaved:
Becoming grammes per square metre with the woven appearance of this silvalin warp-knit cloth of pure and beautiful tower is 600g/m
2Mei Tasi 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 Mei Tasi 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 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 Mei Tasi fiber loom cloth, and described superficial layer is formed by acrylic fiber, PPS fiber and polyster fibre lapping after mixing.
