Abstract
The utility model provides expanded glass-fiber woven filter cloth double coatings, which is excellent in wear resistance and folding endurance. The filter cloth is characterized in that both sides of the expanded glass-fiber woven cloth are respectively coated with a polytetrafluoroethylene material layer, and the expanded glass-fiber woven cloth is expanded alkali-free glass-fiber backed cloth. The filter cloth has the advantages that since two sides of the expanded glass-fiber woven filter cloth are respectively coated with a micro-fine material coating, most dust on the windward side is blocked on the surface of the woven cloth and cannot enter the inside of a filter material, so that residual resistance of the dedusting filter material is small in variation and the service life of the filter material is prolonged; coating materials on the lee side enable the glass-fiber woven filter cloth with double coatings to be softer, the coatings on the surfaces of the woven cloth prevent direct friction among cages of glass fiber materials, friction frequency of cages of the filter material is increased, and thereby the service life of the filter material is prolonged.
Description
Technical field
The utility model relates to woven pair of coating filter cloth of a kind of glass varicosity, the filter cloth that particularly a kind of filtering material that is used for flue gas and treating flour dust is made.
Background technology
At present, the glass fiber machine woven filter material that uses in industries such as iron and steel, metallurgy, cement, electric power, chemical industry, pharmacy mainly contains woven overlay film filter cloth of glass and the woven single coating material of glass.The woven covering material of glass the obscission of film occurs easily in use, and the wear-resisting and folding quality of glass coated filter material is limited.
The utility model content
Be to solve foregoing problems, the utility model provides a kind of wear-resisting and folding quality than woven pair of coating filter cloth of more excellent glass varicosity.This filter cloth is: on the two sides of the woven cloth of varicosity glass fibre, all be coated with last layer polytetrafluoroethylene (PTFE) material.The woven cloth of described varicosity glass fibre is a kind of varicosity alkali-free glass fibre backed cloth.
Superior effect of the present utility model is:
All there is the fine coated substance of one deck on the two sides of woven pair of coating filter cloth of this glass varicosity, the most of dust in windward side is trapped within the surface of woven cloth and can not enters the inside of filtrate, make the residual resistive of deashing filtrate change not quite the service life of having improved filtrate; The coating material of lee face makes the soft more of woven pair of coating filter cloth of glass, and the coated substance on woven cloth surface has blocked the direct friction between the bag cage of glass fiber material, increases the friction number of times between the bag cage of filtrate, the service life of having improved filtrate.

1-coating material;
The woven cloth of 2-varicosity glass fibre;
3-coating material.
The specific embodiment
As shown in Figure 1, the utility model provides a kind of glass varicosity woven pair of coating filter cloth, at the two-sided last layer polytetrafluoroethylene (PTFE) material 1 and 3 that all is coated with of the woven cloth 2 of varicosity glass fibre; The direction of arrow is air-flow direction among the figure.
The woven cloth of described varicosity glass fibre is a kind of varicosity alkali-free glass fibre backed cloth.
The utility model is dropped into actual operating mode to be used, through implementing proof, continuous operation temperature of the present utility model is 120 ℃ ~ 260 ℃, moment, serviceability temperature was 300 ℃, brute force 〉=2800N/5 * 20 ㎝ radially, broadwise brute force 〉=3000N/5 * 20 ㎝, radial fragmentation percentage elongation≤25%, broadwise elongation at break≤25%, air permeability 4-6m
