Abstract
The invention relates to a high strength fold-resistant glass fiber filtering material. The filtering material comprises extruded glass fiber and a fluorine-containing material. The filtering material is characterized by firstly weaving a base fabric with the extruded glass fiber yarn, then impregnating a fluorine-containing emulsion on the base fabric, and compositing a polytetrafluoroethylene film with micropores on the surface after a drying and plasticizing treatment. Firstly, the base fabric is woven by medium-alkali or alkali-free extruded glass fiber yarn; secondly, the base fabric is impregnated in the fluorine-containing emulsion of a fluorocarbon emulsion or a fluoro-silicon emulsion, and after impregnation, the weight ratio of the base fabric and the fluorine-containing emulsion is 85-90% : 10-15%; then, drying for 2-5 minutes at the temperature of 120 DEG C-190 DEG C in a drying oven to make glue on the base fabric dried and solidified on the base fabric; and finally, the polytetrafluoroethylene film with micropores is composited on the surface by using a hot-pressure composite method or an adhesive bonding method. Gas permeability of the filtering material is greatly improved; corrosion resistance and self-purification capability are increased, thereby greatly improving service life of products.
Description
Technical field
The present invention relates to a kind of expansion glass fiber filter material; Be specifically related to infuse fluorine material on a kind of expansion glass fiber base cloth; And at base cloth surface recombination microporous poly tetrafluoroethylene, the high strength folding glass fiber filter material of process industry smoke filtration articles for use.
Background technology
It is a kind of novel filter material of developing in recent years that glass fibre combines with fluorine material.It has given full play to inorganic glass fiber and Organic fluoride performance advantage separately, and the gas cleaning and the material that are widely used in industries such as cement, kiln, flour, pigment, waste incineration reclaim.
Present stage, filtering material all used polytetrafluoroethylene (PTFE) to be main material.Under high temperature, water content is big, acid-base value is higher and Dust Capacity is many condition of work, it is short that the filtering material ubiquity service life.Broken bag rate height, maintenance or the high problem of replacement cost.
Summary of the invention
To the problem of above-mentioned existence, main task of the present invention is to provide a kind of high strength folding glass fiber filter material.
In order to solve above technical problem; A kind of high strength folding glass fiber filter material of the present invention; It comprises expansion glass fiber and fluorine material; It is characterized in that: at first be made into base cloth, again at dipping fluorine-containing latex on the base cloth and after drying plastics processing, at the poly tetrafluoroethylene of its surface recombination band micropore with expanded glass fiber yarn.
Further, said fluorine-containing latex is fluorine carbon emulsion or fluoro-silicone emulsion.
Further, described expansion glass fiber is middle alkali or alkali-free glass fibre.
Further, the method for said composite microporous poly tetrafluoroethylene is that hot pressing is compound or adhesive is bonding.
The invention has the advantages that:
The base cloth that it adopts the varicosity glass fiber yarn to be made into is a skeleton; Thereby greatly improved the gas permeability of filtering material; Adopt fluorine silicon or fluorocarbon material simultaneously; Improve its corrosion resistance and self-cleaning property, prior fluorine silicon or fluorocarbon material have improved the intensity and the folding quality of glass fibre, thereby the service life of having improved product greatly.
The specific embodiment
The expansion glass fiber yarn of alkali or alkali-free is made into base cloth at first using, and base cloth is immersed in the fluorine-containing latex of fluorine carbon emulsion or fluoro-silicone emulsion, after the proofing again; The percentage by weight of base cloth and fluorine-containing latex is: 85-90%: 10-15%; Then, in drying oven with 120 ℃-190 ℃ temperature baking 2-5 minute, with the glue baking and curing on the base cloth on base cloth; At last, at the poly tetrafluoroethylene of its surface or mode composite band micropore that adhesive bonding compound with hot pressing.
The comparative example:
Performance comparison
Can know that by above-mentioned example the application of fluorine-containing latex can significantly improve the folding resistance of expansion glass fiber.
