Abstract
The utility model discloses a terylene superfine surface layer needle-punched filter material which comprises an intermediate layer, wherein an upper composite surface layer is arranged above the intermediate layer, a lower composite surface layer is arranged below the intermediate layer, and an outer layer is arranged on the upper composite surface layer. Compared with the prior art, the utility model has the advantages of high-temperature resistance, acid resistance, moderate alkaline-resisting performance, high filtering accuracy, good dimensional stability, good air permeability and high tensile strength.
Description
[technical field]
The utility model relates to a kind of terylene super fine surface layer needle punched filter material.
[background technology]
At present; There is the occasion of requirements at the higher level in cement plant, steel plant, power plant, chemical plant etc. to the strainability of filtrate, but existing filtrate is because filtering accuracy is lower, and gas permeability is poor; Emission request be can't reach, inconvenience, disadvantage caused in process of production.
[utility model content]
The utility model is in order to solve above-mentioned deficiency, a kind of filtering accuracy height, good permeability is provided, has been easy to the terylene super fine surface layer needle punched filter material of deashing.
The above-mentioned purpose of the utility model realizes through following technical scheme: a kind of terylene super fine surface layer needle punched filter material; Comprised the intermediate layer; It is characterized in that: top, said intermediate layer is provided with composite cover; Composite cover is provided with skin on said intermediate layer is arranged with composite cover, is said.
Said intermediate layer is the woven layer of cloth of polyester filament.
The said composite cover of going up constitutes by polyester staple fiber and terylene medium-length fibre with following composite cover, and said polyster fibre ratio is that 20%～40%1.56dtex*38mm mixes 60%～80%2.2dtex*51mm or 2.78dtex*65mm.
Said skin is the terylene super fine surface layer, and its specification is polyster fibre 0.8dtex～1.56dtex*38mm.
The utility model advantage compared with prior art is:
1, high temperature resistant: 130 ℃ of long-term serviceability temperatures, moment serviceability temperature be 150 ℃.
2, acidproof, alkaline resistance properties is moderate.
3, filtering accuracy is high: the product dust-collecting face is that superfine fibre filters surface layer, and the filtering surface dust catching efficiency is high, is easy to deashing, has improved the filter efficiency and the filtering accuracy of product greatly, long service life.
4, dimensional stability is good, good permeability, and tensile break strength is high.
[description of drawings]
Fig. 1 is the structural representation of the utility model.
In the accompanying drawing, the 1-intermediate layer; The last composite cover of 2-; Composite cover under the 3-; 4-is outer.
[specific embodiment]
Below in conjunction with accompanying drawing the utility model is further detailed:
