Description
Technical field
The present invention relates to a kind of preparation method of coated filter material, belong to filtering material preparing technical field.
Background technology
At this stage, still using thermal power generation as main power source mode, thermal power output is 80% left side of gross generation
The right side, the rising of other energy prices promotes most heat power station to be continuing with coal for main fuel, will in coal-fired process
Waste gas is constantly produced, in order to meet the requirement of various processes, the purpose of energy regenerating is reached, to the High Temperature Gas of these dust-ladens
Body is required for carrying out dust removal process.Before age 21 century, filtering material is mainly the natural fibers such as cotton, hair, and filtering material is deposited
It is low in temperature in use, the defect such as hydroscopicity is high, not acidproof, therefore except special requirement, these filterings are typically now rarely employed
Material.At present, filtering material develops towards high temperature resistant, efficient, high filtering velocity, long-life, inexpensive direction, successively occurs in that glass
The filtrates of good performance such as fiber, fragrant adoption phthalein amine, polytetrafluoroethylene (PTFE).Wherein, polytetrafluoroethylene film fiberglass overlay film
Filtrate is the developing direction of high temperature resistance filtration material, and it is in the glass base fabric overlying film micropore poly- four being surface-treated through special formulation
The novel filter material that fluoroethylene film is made, supports volume morphing difference to include continuous glass fibre woven fabric according to glass fibre
Coated filter material, buiky yarn coated filter material and fiberglass needled mat coated filter material, it combines glass fibre and expanding microporous poly
The advantage of tetrafluoroethene film, the good characteristic of service life length high with high temperature resistant, efficiency of dust collection.
Because the use environment of filtering material has higher requirement to the performance of filtering material in itself, therefore, in filter material
Material field, high-performance fiber is constantly subjected to the concern of people, currently, and the high-performance fiber for filtering material mainly includes aramid fiber
1313rd, polyimides, polyphenylene sulfide and glass fibre etc., aramid fiber 1313 oxidative resistance are poor, compared with facile hydrolysis destruction；Polyimides valency
Lattice are expensive, and rely primarily on import；Polyphenylene sulfide inoxidizability is general, and its temperature in use is inversely proportional with oxygen content, and poly-
Acid imide can cause environmental pollution in process of production with polyphenylene sulfide；Although glass fibre is with higher tensile strength and chi
Very little stability, but glass fibre easily produces electrostatic during woven, and glass fibre is intolerant to hydrogen fluoride corrosion, institute
It is necessary to prepare a kind of coated filter material of excellent anti-corrosion performance Antistatic type.
The content of the invention
The technical problems to be solved by the invention：Easily produced during woven for existing membrane-laminated fiberglass filter media
Raw electrostatic, and glass fibre intolerant to hydrogen fluoride corrosion the problem of there is provided a kind of preparation method of coated filter material.
In order to solve the above technical problems, the present invention is using technical scheme as described below：

Wire drawing process, standing is cooled to room temperature, obtains a diameter of 10~15 μm of substrate glass fiber；
（2）In mass ratio 1:10, peach gum is mixed with deionized water, swelling treatment obtains peach gum mixed liquor, homogenized is prepared into
Mixed liquor is homogenized, fluorite is taken and crushed 200 mesh sieves, obtain fluorite powder, in mass ratio 1:10, fluorite powder is mixed with homogenate
Liquid is mixed, and ultrasonic disperse obtains mixed dispersion liquid, mixed dispersion liquid is placed in spray gun, is uniformly sprayed to substrate glass fiber table
Face；
（3）After the completion of to be sprayed, solidification is stood, curing glass fiber is obtained, and calcine to obtain modified glass-fiber, by modified glass fibre
Dimension twisting shaping, with the winding method winding shaping of taper, is prepared into modified glass-fiber yarn and is placed in automatic arrow shaft and knit sample
In machine, weave cotton cloth handle modified glass-fiber is weaved cotton cloth；
（4）The polytetrafluoroethylene (PTFE) and modified glass-fiber for cutting identical size are weaved cotton cloth, and are placed in hot pressing by size is overlapping and are covered
In film machine, hot pressing overlay film to thickness is 5~8 μm, and standing is cooled to room temperature, you can be prepared into a kind of corrosion-resistant Antistatic type overlay film
Filtrate.
Step（3）Described weaving cotton cloth is processed as being weaved cotton cloth by through close × filling density=100 × 80 piece/10cm.
Step（4）Described hot pressing laminating machine hot pressing mulching plastic film condition is to control hot pressing coated temperature to be 400~410 DEG C, is covered
Resultant pressure is 1~2MPa, is dewaxed as 480~500 DEG C, the dewaxing time is 28~30s.
The present invention is compared with other method, and advantageous effects are：
（1）The present invention is mixed with melten glass liquid by choosing blast-furnace cinder and sodium carbonate, silica sand and dolomite, after water quenching
Wire drawing collects glass fibre as matrix, and fluorite powder is dispersed in peach gum mixed liquor, glass fiber matrix surface is carried on,
Carbonized after calcining and be cured to fiberglass surfacing, effectively prevent surface corrosion of the hydrogen fluoride to coated filter material；
（2）Modified fiberglass woven cloth through hot pressing aluminum coated steel, is made it effectively be tied with poly tetrafluoroethylene by the present invention
Close, be prepared into PTFE membrane filter material, because polytetrafluoroethylene (PTFE) effectively coats filter material surface in the present invention, place it in absolutely
Edge region is isolated, and membrane-laminated fiberglass filter media can not be produced electrostatic, so that improving glass fibers easily produces lacking for electrostatic
Fall into.
