Abstract
The utility model relates to a needling filter material which comprises a base fabric and fiber layers. The needling filter material is characterized in that: the fiber layers are symmetrically needled and pasted on the upper and lower surfaces of the base fabric; the base fabric is weaved by alkali-free glass fibers in a longitude and latitude direction according to the proportion of 10:8, and the base fabric can is immersed by polyfluortetraethylene before being used; the fiber layers are mixed by vinylon and polyphenylene sulfide according to the proportion of 3:7, and the fiber layer and the base fabric are pasted in a needling manner. By adopting the glass fiber fabric as the base fabric, the fabric can be prevent from contraction and can keep stable performance, and the effect of corrosion resistance, high-temperature resistance and water-proof and oil-proof resistances can be achieved. The superfine fibers on the surface of the filter material are adopted, the filtering precision is high, and the surface of the material is smooth and is easy to remove ash after being singed and press-polished. The fabric surface is smooth and soft after immersion, hot-rolling and sizing are carried out, the base fabric has the same corrosion-resisting performance as the polyfluortetraethylene, is particularly suitable for severe conditions such as cement drying and dust filtering in a cement rotary kiln, a shaft kiln and the like, and can bear high filtering air speed in the practical use.
Description
Technical field
The utility model relates to a kind of filtering material, particularly a kind of acupuncture filtering material.
Background technology
Materials such as general filter felt, cloth can the following temperature of anti-1500 ° of C, but to containing the occasion of the composition that is corrosive in the flue gas, as: steel plant's slag micropowder gathers dust, the chemical plant, the industrial and mineral of zinc is arranged, then acidproof, the alkali resistance to filtering material has higher requirement, therefore, in the existing technology, filtrate exists dust removing effects not up to standard, the high Wei that asks of dedusting cost, and will under bad working environments, use filtering material effectively, and keep stable performance, remedy temperature space, then need a kind of filtering material of suitable above-mentioned operating mode.
Summary of the invention
In order to overcome the problems referred to above that exist in the existing technology, the purpose of this utility model provides a kind of acupuncture filtering material, and it not only can make filtering material use under bad working environments effectively, and the while is the stable filter effect of tool again.
The utility model is realized above-mentioned purpose by following technical proposals.
A kind of acupuncture filtering material is made up of base cloth and fibrage, it is characterized in that fibrage is pasted in the top and bottom symmetry acupuncture of base cloth.
Described base cloth selects for use alkali-free 80s12 thigh glass fiber yarn to be made into (300 grams/m2), carry out the polytetrafluoroethylene (PTFE) dipping before base cloth uses earlier in warp, 10: 8 ratios of latitude.
Described fibrage, select for use: polyvinyl: polyphenylene sulfide=ratio was mixed in 3: 7, utilized acupuncture to paste with above-mentioned base cloth and formed.
A kind of acupuncture filtering material described in the utility model, after above-mentioned technology making, carry out impregnation process again, the dipping solution ratio is: ptfe emulsion accounts for 18-20%, hydroxy-silicone-oil emulsion accounts for 10-12%, and coupling agent accounts for 1.0-2.0%, and all the other are water, dipping is 1 minute before filter cloth enters stentering forming, dry through thermal finalization thereafter.
A kind of acupuncture filtering material described in the utility model, thickness is 2.0～2.1mm.
Usefulness of the present utility model is: adopt glass cloth to make base cloth, carry out the polytetrafluoroethylene (PTFE) dipping before the use earlier, to increase single thread force, strengthen glass base cloth decay resistance and hydrophobicity performance, reach effect corrosion-resistant, high temperature resistant, waterproof and oilproof.Can avoid cloth cover to shrink, keep stable performance.Semi-finished product are after press polish is singed, and by the dipping rolling and molding, the cloth cover smooth pliable has the corrosion proof function equal with polyphenylene sulfide, and chemical stability is good, adopts surperficial superfine fibre, can improve filter effect.Filter and generally can reach 30 milligrams every cubic metre.Be specially adapted to bad working environments such as rotary cement kiln, shaft kiln cement oven dry filtrating smoke dust, can bear higher filtration velocity in actual use, the filtering accuracy height.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
In Fig. 1: 1 one base cloths, 2 one fibrages.
The specific embodiment
To consult shown in the accompanying drawing below, the utility model will be further described.
As accompanying drawing 1, shown in the structural representation of the present utility model, the utility model provides a kind of acupuncture filtering material, it is characterized by at the top and bottom of base cloth 1 symmetry acupuncture stickup fibrage 2, and described base cloth 1 is made into (300 gram/m for selecting alkali-free 80s12 thigh glass fiber yarn for use in warp, 10: 8 ratios of latitude
2), described fibrage 2 mixes in 3: 7 ratios for selecting polyvinyl, polyphenylene sulfide for use, utilizes acupuncture to paste with above-mentioned base cloth and forms, and the thickness of material is 2.0～2.1mm.
The utility model is that (5 * 20cm) 1800N, (5 * 20cm) 1800N, percentage elongation are warp-wise 0.5% to broadwise to warp-wise, broadwise 0.5%, 180 ℃ of normal working temperatures, 210 ℃ of instantaneous temperatures through its fracture strength of experiment confirm.
Claims (2)
1. an acupuncture filtering material comprises base cloth and fibrage, it is characterized in that: fibrage is pasted in symmetry acupuncture in the top and bottom of base cloth.
2. by the described a kind of acupuncture filtering material of claim 1, it is characterized in that: described base cloth, it is made in warp, 10: 8 ratios of latitude for alkali-free glass fibre yarn.
