Description
Technical field
The present invention relates to filter technical field, be specifically related to organic micro porous filtration body that a kind of processing method of organic micro porous filtration body and processing obtain.
Background technology
Pottery disk vacuum filter advantage clearly, as energy-conservation, low noise, filter medium consumption less, product moisture is lower etc., in mine, the field such as metallurgy, chemical industry, food, material is widely applied.One of core component of pottery disk vacuum filter sinters with ceramic powder the ceramic fan-shaped screen plate processed.In use often find, the micropore of pottery fan-shaped screen plate is filtered the subparticle comprised in material very soon and blocks, and it cleans and regeneration is very difficult, even soak with red fuming nitric acid (RFNA), oxalic acid and be all difficult to clean the tamper in micropore under hyperacoustic effect, thus greatly reduce the service life of filter, need frequent filter of changing to ensure the normal operation of filtering, cause ceramic disk vacuum filter use and maintenance cost high.
For above situation, people have developed the organic micro-porous filtration plate produced based on organic polymer powder, because high-molecular organic material has certain plasticity, make organic micro-porous filtration plate its micropore size in filtration or blowback process can produce certain elastic deformation, thus significantly reduce the probability of blocking.Meanwhile, because high-molecular organic material can tolerate highly basic or the strong acid even immersion of hydrofluoric acid etc. at normal temperatures, thus the micropore of organic micro-porous filtration plate can being cleaned or regenerate, is the very promising filtering material of one.
The method of the organic micro-porous filtration plate of existing preparation mainly contains two kinds, and namely two harden legal and one sinter molding method.Method disclosed in the patent application of publication number CN101543691A be two harden legal, first sintered by the high-molecular organic material such as polyethylene, polypropylene and make two pieces of fan-shaped microwell plates, then two pieces of fan-shaped microwell plates are by boning at intermediate fabrication supporter, then or be sintered into one, and make organic micro-porous filtration plate.Organic micro-porous filtration plate Problems existing that the method obtains is, if adopt glue bond method to obtain, two pieces of fan-shaped microwell plate adhesion strengths are low, instructions for use can not be met, in the course of the work, when such as vacuumizing filtration or blowback etc. have External Force Acting, two pieces of fan-shaped microwell plates are easy to distortion and are separated, and cause directly scrapping; If adopt sintering method to obtain, because fan-shaped microwell plate is organic polymer material, sintering temperature is too low, the bond strength of two pieces of fan-shaped microwell plates is low, is easily out of shape separation in the course of work, can not meet instructions for use, sintering temperature is too high, fan-shaped microwell plate can be out of shape, and particularly causes the distortion of filtrate duct or the blocking of two pieces of fan-shaped microwell plate inside, directly can affect filter efficiency and the service life of obtained fan-shaped screen plate.Disclosed in the patent application of publication number CN101773748A, method is integrated sinter molding method, comprise mould installation, filler, exert pressure, heat-agglomerating, the step such as cooling withdrawing pattern.Technological difficulties of one sinter molding method are exactly how in organic micro-porous filtration plate, to form the filtrate duct be evenly arranged, to ensure filtration efficiency and the service life of fan-shaped screen plate.The patent application of publication number CN101773748A refer to " scribbling taking ultrahigh molecular weight polyethylene powder 3 loading prepared in the die cavity of mold filling thing 4 of releasing agent ", wherein, the effect of mold filling thing 4 should support the filtrate duct forming organic micro-porous filtration plate inside exactly.But in detail openly how mold filling thing 4 is not removed in that patent.If the words removed by heat fused in the heat-agglomerating stage, due to be difficult to ensure the filtrate duct of mold filling thing 4 in organic micro-porous filtration plate be fully formed and not redeformation again heat fused remove, under normal circumstances, when heat-agglomerating, mold filling thing 4 also can rise and softening transform with temperature, so adopt the easy Collapse Deformation in filtrate duct in organic micro-porous filtration plate obtained in this way, even block, directly affect filter efficiency and the service life of obtained fan-shaped screen plate.In addition, the localization method in the shape of mold filling thing 4, material and the filtrate duct in organic micro-porous filtration plate is all not mentioned.
