Abstract
The utility model provides a kind of middle high temperature filtering material of non-woven fabricbase cloth metalized, and this filtering material has metal level in the outer plating of non-woven fabricbase cloth, is connected with top layer outside metal level.The middle high temperature of the present utility model filtering material of non-woven fabricbase cloth metalized has the advantages such as static electricity resistance is good, uniformity is good, high temperature resistant, adhesion is good, can be used for the middle high-temperature bag dust removal in the fields such as waste incineration, thermal power generation, cement, iron and steel, chemical industry, metallurgy.
Description
Technical field:
The utility model belongs to fabrics for industrial use field, particularly relates to the filtering material of a kind of middle high temperature by non-woven fabricbase cloth metalized.
Background technology:
In the industrial circles such as petrochemical industry, smelting iron and steel, coal-burning power plant, waste incineration, cement, the flue dust that process portion produces has the features such as flammable, explosive, high temperature, use process in due to dust and dust, rubbing between dust and filtrate easily produces a large amount of electrostatic, as can not be in time electric charge eliminated, fire or explosion accident will be produced.The flue dust of high temperature is then had higher requirement to the use of filtering material.Along with science and technology and the development of modern crafts, people also more and more pay attention to the aspect such as air quality, personal protection, therefore, need to use high-temperature-resistant antistatic filtering material to process flue dust.There is the shortcomings such as lack of homogeneity, antistatic performance is unstable, decay is fast, sheet resistance is bigger than normal in existing antistatic filtering material.
The domestic and international research about antistatic filtering material is less at present, patent of invention (201310119167.5) provides a kind of Anti-static polytetrafluoroethylfilter filter bag and preparation method thereof, the method base cloth twists Split Down by polytetrafluoroethylfilament filament and stainless steel fibre, weave mutually form by warp, latitude, be coated with nonwoven layers at the upper and lower surface of Ji Bu, its electrostatic-proof function layer is different from this patent.Utility model patent (201120341764.9) provides a kind of antistatic blending filter felt, what this filter felt comprised conductive fiber and the blending of polyacrylonitrile fibre cross lapping meets knoisphere, the base cloth layer of polyacrylonitrile fibre long filament braiding and the bottom of polyacrylonitrile fibre cross lapping, and its electrostatic-proof function layer is different from this patent.
Summary of the invention:
The utility model is intended to overcome the deficiencies in the prior art, and object is to provide the filtering material of all good middle non-woven fabricbase cloth metalized of high temperature of a kind of static electricity resistance, uniformity and adhesion.
The purpose of this utility model realizes by following technical measures:
This filtering material has metal level in the outer plating of non-woven fabricbase cloth, is connected with top layer outside metal level.
The purpose of this utility model also realizes by following technical measures:
Described non-woven fabricbase cloth is made up of aramid fiber, polytetrafluoroethylene fibre, polyimide fiber, polyphenylene sulfide fibre, glass fibre, one or more fibers of basalt fibre.
Described metal level is nickel, silver, titanium or chromium metal level.
Described top layer is made up of aramid fiber, polytetrafluoroethylene fibre, polyimide fiber, polyphenylene sulfide fibre, glass fibre, one or more fibers of basalt fibre.
The thickness of described metal level is 0.05-1 μm.
The utility model compared with prior art tool has the following advantages:
In non-woven fabricbase cloth plating layer of metal, accurately can control the thickness of metal level, when reaching like product resistivity, required metal is less, improves the even of antistatic filtering material functional layer; Improve the service life of antistatic filtering material functional layer; The utility model selects high-temperature fibre non-weaving cloth, and at non-woven fabricbase cloth plating metal level, meet the instructions for use of antistatic filtering material under middle hot conditions, widen the application of antistatic filtering material, there is the advantages such as static electricity resistance is good, uniformity is good, high temperature resistant, adhesion is good, can be used for the middle high-temperature bag dust removal in the fields such as waste incineration, thermal power generation, cement, iron and steel, chemical industry, metallurgy.
