Abstract
The utility model discloses a kind of glass fibre composite filtering cloth, comprise the base cloth layer by glass fibre and the blending of polytetrafluoroethylene fibre intertexture, base cloth layer surface is by the tack coat of impregnation fluid, and tack coat is bondd by high temperature hot pressing outward the polytetrafluoroethylmicroporous microporous membrane layer of compound.The beneficial effects of the utility model are, glass fibre and polytetrafluoroethylene fibre are carried out blending and forms base cloth layer, and in fluoropolymer solutions, pretreatment is carried out to base cloth layer, considerably increase the adhesive fastness of base cloth layer and polytetrafluoroethylene film layer, reduce film obscission, thus improve the service life of filter cloth; Adopt the less glass fibre of diameter to weave cotton cloth, improve folding quality and the filter efficiency of filter cloth to greatest extent.
Description
Technical field
The utility model relates to filtering material technical field, particularly relates to a kind of glass fibre composite filtering cloth.
Background technology
Glass fibre has light weight, high-strength, anticorrosion, insulation, insulation and the plurality of advantages such as low price.Glass fabric and high molecular weight ptfe Film laminated filtering material are the filtering materials of a kind of function admirable in recent years occurred, this material has given full play to inorganic material and organic material performance advantage separately, there is the features such as high temperature resistant, corrosion resistance is strong, dimensionally stable is good, be widely used in the high temperature off-gas recovery fields such as cement, metallurgy, carbon black and coal-burning boiler.
But the composite not folding of fiberglass surfacing coating polytetrafluoroethylene floor, belongs to fragile material, the not acid gas of resistance to compound, and easily occurs rete obscission.Therefore in use, service life is shorter.And along with industrial expansion, the requirement of flue filtering material is improved constantly.For improving the service life of smoke filtration articles for use, developing folding, glass fiber material that is anti-aging, the acid gas of resistance to compound is key subjects.
Utility model content
The purpose of this utility model is the deficiency for existing glass fiber filter material, provides a kind of folding, high temperature resistant, anti-aging, corrosion-resistant, and the glass fibre composite filtering cloth that filter effect is good.
The utility model is achieved through the following technical solutions, a kind of glass fibre composite filtering cloth, comprise the base cloth layer by glass fibre and the blending of polytetrafluoroethylene fibre intertexture, base cloth layer surface is by the tack coat of impregnation fluid, and tack coat is bondd by high temperature hot pressing outward the polytetrafluoroethylmicroporous microporous membrane layer of compound.
Preferably, the diameter of described glass fibre is 2 ~ 5 μm, and the diameter of described polytetrafluoroethylene fibre is 20 ~ 40 μm.
Preferably, in the base cloth layer of described glass fibre and the blending of polytetrafluoroethylene (PTFE) intertexture, the percentage by weight of glass fibre is 60 ~ 80%.
Preferably, described maceration extract is made up of fluoropolymer, fluorine-containing coupling agent, organic film former and water.
Preferably, the hot pressing temperature of the polytetrafluoroethylmicroporous microporous membrane layer of described high temperature hot pressing bonding compound is greater than 180 DEG C.
The beneficial effects of the utility model are, glass fibre and polytetrafluoroethylene fibre are carried out blending and forms base cloth layer, and in fluoropolymer solutions, pretreatment is carried out to base cloth layer, considerably increase the adhesive fastness of base cloth layer and polytetrafluoroethylene film layer, reduce film obscission, thus improve the service life of filter cloth; Adopt the less glass fibre of diameter to weave cotton cloth, improve folding quality and the filter efficiency of filter cloth to greatest extent; Filter cloth filter efficiency of the present utility model can reach more than 99.99%, outlet dust-laden close " zero-emission ", and have ash-removal effect good, energy consumption is low, suitably can improve the rate of filtration according to base material feature simultaneously.
