Abstract
The utility model provides an aramid compound filter material. The aramid compound filter material is characterized by comprising an aramid compound needled felt and a polytetrafluoroethylene film layer which covers one side of the aramid compound needled felt. The filter material with superfine glass fiber base cloth is high in strength and good in size stability; the filter material is formed by blending aramid and glass fibers and is dipped in a PTFE (Poly Tetra Fluoro Ethylene) emulsion wholly, thus being high in application temperature and good in erosion resistance; the filter material utilizes a superfine fiber surface layer and is dipped in the PTFE emulsion wholly, so that the physical and chemical properties of the filter material are remarkably improved; the surface of the filter material is coated with a film, so that the surface filtration is achieved, the filter material is high in filtration accuracy and good in ash removal property, and the service life of the filter material is effectively prolonged.
Description
Technical field
The filtering material that provides a kind of Environmental-protecting dust-removing to use is provided the utility model, and spy is standby is a kind of aramid fiber composite filtering material.
Background technology
At present in high temperature fume dust removal field, especially for the flue gas ash removal field of the industry such as building materials, chemical industry, due to smoke components complexity, the operating mode of the complicated conditions such as air quantity is large, wind speed is high, after long-time use, easily there is the powerful phenomenons such as deashing property weakens that decline, filter in filtrate, especially in the large operating mode of some dust electrostatics, even there is the accidents such as dust explosion, had a strong impact on the normal order of operation and the production of deduster.
The filtering material that the operating modes such as most of cement plants, bituminous mixing plant, chemical plant are used mostly is aramid fiber Nomex filtrate.In filtrate use procedure, there are some problems: due to factors such as the complicated flue gas corrosion of smoke components of operating mode discharge are large, oxygen content is high, water capacity is large, fine dust is many, cause and cause aramid fiber filtrate and occur that burn into powerful declines, sticks with paste the phenomenons such as bag, causes filtrate breakage, inefficacy.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provides that a kind of corrosion resistance is good, tensile strength is high, filtering accuracy is high, the aramid fiber composite filtering material of long service life.
The utility model aramid fiber composite filtering material, comprises aramid fiber compound spiked felt, and at the laminating polytetrafluoroethylene film layer of described aramid fiber compound spiked felt one side.
Described aramid fiber compound spiked felt comprises dawn fiber needled felt in aramid fiber and glass, and at aramid fiber and the glass superfine fibre layer of its dust-collecting face composite acupuncture.
Described aramid fiber compound spiked felt entirety is through PTFE emulsion impregnation process.
In described aramid fiber and glass, dawn fiber needled felt comprises superfine glass fiber base cloth layer, and in the aramid fiber of described superfine glass fiber base cloth layer two-side needled and glass dawn fibrage.
Described superfine glass fiber base cloth layer is the superfine glass fiber base cloth layer through PTFE emulsion impregnation process.
The utlity model has following advantage:
1, adopt superfine glass fiber base cloth, filtrate brute force is high, good stability of the dimension;
2, adopt aramid fiber and glass blending, filtrate entirety is through PTFE emulsion impregnation process in addition, and serviceability temperature is high, and corrosion resistance is good;
3, adopt superfine fibre surface layer and the processing of PTFE emulsion mass-impregnation, physicochemical property significantly improves;
4, surface coating is realized surface filtration, and filtering accuracy is high, and deashing is good, and effectively extend service life.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model aramid fiber composite filtering material
1-polytetrafluoroethylmicroporous microporous membrane layer; 2-aramid fiber and glass superfine fibre surface layer; Dawn fibrage in 3-aramid fiber and glass; 4-superfine glass fiber base cloth layer; Dawn fibrage in 5-aramid fiber and glass.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is made to detailed description.
The utility model aramid fiber composite filtering material as shown in Figure 1, comprises polytetrafluoroethylmicroporous microporous membrane 1 successively from dust-collecting face, aramid fiber and glass superfine fibre surface layer 2, dawn fibrage 3 in aramid fiber and glass, superfine glass fiber base cloth layer 4, dawn fibrage 5 in aramid fiber and glass.
Superfine glass fiber base cloth is obtained to superfine glass fiber base cloth layer 3 through PTFE emulsion impregnation process;
Dawn fiber in superfine glass fiber base cloth layer two-side needled aramid fiber and glass, makes dawn fibrage 2,4 in aramid fiber and glass.
Now, in superfine glass fiber base cloth layer, aramid fiber and glass, dawn fibrage 2,4 forms dawn fiber needled felt in aramid fiber and glass.
In aramid fiber and glass, dust-collecting face composite acupuncture one deck aramid fiber of dawn fiber needled felt and glass superfine fibre layer 1, make aramid fiber compound spiked felt, then by aramid fiber compound spiked felt entirety process PTFE emulsion impregnation process.
Finally, at aramid fiber and the laminating polytetrafluoroethylmicroporous microporous membrane 1 of the ultra-fine facing surface of glass, make aramid fiber composite filtering material.
The utility model aramid fiber composite filtering material adopts superfine glass fiber base cloth, and filtrate brute force is high, good stability of the dimension; Adopt aramid fiber and glass blending, filtrate entirety is through PTFE emulsion impregnation process in addition, and serviceability temperature is high, and corrosion resistance is good; Adopt superfine fibre surface layer and the processing of PTFE emulsion mass-impregnation, physicochemical property significantly improves; Surface coating is realized surface filtration, and filtering accuracy is high, and deashing is good, and effectively extend service life.
These are only preferably detailed description of the invention of the utility model, but protection domain of the present utility model is not limited to this, the variation that any those skilled in the art of being familiar with can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, the utility model protection domain should be as the criterion with the protection domain of claims.
