Abstract

The utility model relates to a garbage soot filtering material, which comprises a grey cloth, and wefts, warps and a polyfluortetraethylene surface membrane for weaving the grey cloth, and is characterized in that the filtering material adopts fiber glass as a main body and is blended with polyfluortetraethylene long-yarn fibers, the warps adopt alkali-free fiber glass, polyfluortetraethylene emulsion is soaked on the alkali-free fiber glass to form a protection membrane, the wefts adopt 80 alkali-free glass fibers, 12 shares of bulked yarns and polyfluortetraethylene single yarn fibers to be blended, after the warps and the wefts are woven to form the grey cloth according to the craftwork requirements, the grey cloth is soaked in the polyfluortetraethylene, and finally the grey cloth which is undertaken the soaking treatment is coated with a polyfluortetraethylene membrane at a grey surface. Since a layer of polyfluortetraethylene emulsion is soaked on the fiber glass yarns, the original size of the fiber glass yarns is stable, the fiber glass yarns resist the high temperature, and on the basis of the large tensile strength, the flexibility, the hydrophobicity and the chemical-corrosion resistance are added; and the wefts adopts the bulked yarns, so the surface for capturing the dust is increased, and the time for capturing the dust is prolonged.

Description

A kind of rubbish filtrating smoke dust material

Technical field

The utility model relates to a kind of glass fiber filter material, refers more particularly to a kind of rubbish filtrating smoke dust material.

Background technology

Glass fiber filter material is high temperature resistant with it, corrosion resistance is strong, stable performance, and be widely used in the filtering material field, especially at building materials, metallurgical, chemical industry, industry purposes such as the energy are wider, in order further to adapt to it at high temperature, moisture, the working condition that oxygen content is big and acid-base value is higher uses down, the filtering material that a kind of polytetrafluoroethylcomposite composite film is arranged in the existing technology, it is by glass fibre, two kinds of materials of polytetrafluoroethylene (PTFE) are composited, wherein glass fibre is a base cloth, polytetrafluoroethylene (PTFE) is a skin covering of the surface, by binding agent both bondings are formed, but above-mentioned composite membrane filtering material, owing to weave the warp thread of base cloth, there is not blending to go into the polytetrafluoroethylene (PTFE) composition in the weft yarn, only covering polytetrafluoroethylene (PTFE) after base cloth is made into is skin covering of the surface, contain a large amount of harmful substances being used in, as sulfide, cyanide, in the environment of nitrogen oxide, particularly ought be used for waste incineration, burning boiler, rotary cement kiln kiln tail filtrating smoke dust aspect, because of being not suitable for the abominable operating mode of high temperature, adhesive is easy to fusing or aging, thereby the base cloth of coated filter material and the compound firmness between skin covering of the surface are reduced, even break away from, cause a large amount of dusts to be bonded at the filter bag surface, and life of bag filter is shortened, the broken bag rate increases, thereby increased maintenance cost, influenced economic benefit and efficiency greatly.

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 rubbish filtrating smoke dust material, it not only can make filtering material realize anti-high soda acid effectively, high temperature resistant, and chemical stability is good, be specially adapted to the abominable operating modes of high temperature such as waste incineration, burning boiler, rotary cement kiln kiln tail filtrating smoke dust, can bear higher filtration velocity in actual use, the rate of filtration is fast, the filtering accuracy height, material surface fineness is good, be difficult for sticking ash, thereby make filter efficiency improve long service life, energy efficient, environmental friendliness.

The utility model is realized above-mentioned purpose by following technical proposals.

A kind of rubbish filtrating smoke dust material; it comprises grey cloth and weaves the weft yarn of grey cloth; warp thread and ptfe surface film; it is characterized in that; this filtering material is based on glass; blending the polytetrafluoroethylene (PTFE) monfil; what warp thread adopted is the alkali-free glass fiber yarn; and on the alkali-free glass fiber yarn, flooded one deck ptfe emulsion; form diaphragm; what weft yarn adopted is 80 12 strands of buiky yarns of alkali-free glass fiber and the blending of polytetrafluoroethylene (PTFE) monfil, will through; after weft yarn is woven into grey cloth by technological requirement, again grey cloth is carried out the impregnation process of ptfe emulsion; at last, meet red dog at the grey cloth of process impregnation process and cover poly tetrafluoroethylene.

The alkali-free glass fiber yarn that uses described in the utility model is as warp thread and flooded one deck ptfe emulsion; be meant glass yarn normal temperature dipping 10-20 second in the polytetrafluoroethylene (PTFE) mix reagent; promptly in flux bath, flood with the speed of 15m/min; the glass yarn is carried out the face coat of high temperature (170-190 ℃) through primary coating; making glass yarn surface coating layer thickness is the polytetrafluoroethylene (PTFE) diaphragm of 0.1-0.2 micron; thereby make the monofilm glass fiber yarn; described buiky yarn is meant alkali-free glass fiber yarn resulting buiky yarn behind bulking process; described overlay film is meant after polytetrafluoroethylene (PTFE) emulsification impregnation process has been carried out on the surface of grey cloth; then with the oven dry of 180-200 ℃ of high temperature process; to repair the deep layer breakage that in weaving process, may occur; meet red dog at it again and cover poly tetrafluoroethylene; further improve the filtering accuracy of product and refused outlet capacity; described polytetrafluoroethylene (PTFE) mix reagent; wherein ptfe emulsion accounts for 15-18%; hydroxy-silicone-oil emulsion accounts for 12-14%; coupling agent accounts for 1.0-2.0%, and it is in being water.

Usefulness of the present utility model is, because the alkali-free glass fiber yarn that warp thread adopts, and on the glass yarn, flooded one deck ptfe emulsion, at the original dimensionally stable of glass yarn, high temperature resistant, on the big performance basis of tensile strength, increased pliability, hydrophobicity and chemical resistance, weft yarn is to adopt 80 12 strands of buiky yarns of alkali-free glass fiber and the blending of polytetrafluoroethylene (PTFE) monfil, described buiky yarn has increased the surface area that captures dust, has prolonged the time that captures dust, and the surface of grey cloth is after having carried out polytetrafluoroethylene (PTFE) emulsification impregnation process, meet red dog at it again and cover poly tetrafluoroethylene, further improved the filtering accuracy of product and refused outlet capacity.
