Description

A kind of high-strength ceramic fiber filter paper of filter
Technical field
The present invention relates to cleaner technical field, more particularly to a kind of high-strength ceramic fiber filter paper of filter.
Background technology
Electromotor has air, machine oil, three kinds of cleaners of fuel oil, commonly referred to as " three filters ".They undertake electromotor respectively and enter The filtration of medium in gas system, lubricating system and combustion system.The pattern of air filter has two kinds, i.e. dry type and wet type.It is dry Formula air filter is by a dry type filter element, the cleaner that the impurity in air is separated by (such as paper filter element).
Air filter used by Light-duty Vehicle (contain car, minicar) is generally single-stage, and filtering material is filter paper or non-knits Make cloth.Under nominal air volume flow, the filtration efficiency of filter element should be not less than 99.5%.Heavy goods vehicles are due to working environment Badly, its air filter must be multistage.The first order is spiral-flow type prefilter (such as blade ring, cyclone pipe etc.), is used for Big particle impurity is filtered, more than 80%, second level fine filtering is micropore paper filter element (filter element of commonly referred to as deciding) to filter efficiency, its Filter efficiency is up to more than 99.5%.
Filter element is made using the filter paper of low price, because its filter paper aperture is big, lack of homogeneity, filter efficiency it is low, it is impossible to will be right Harmful impurity is effectively filtered out, and is endangered healthy.
Ceramic fibre is a kind of fibrous light refractory material, with lightweight, high temperature resistant, heat stability be good, thermal conductivity The advantages of low, specific heat is little and mechanical resistant shakes, thus in the industry such as machinery, metallurgy, chemical industry, oil, ceramics, glass, electronics all It is widely used.Rising steadily due to global energy price in recent years, energy-conservation have become China national strategy, at this Under the background of sample, obtain more in China up to the ceramic fibre of 10-30% than traditional resistance to material energy-conservations such as insulating brick and pouring materials More wider array of application, development prospect are very good..
The content of the invention
The object of the invention is exactly for the defect for making up prior art, there is provided a kind of high-strength ceramic fiber filter Paper.
The present invention is achieved by the following technical solutions：

（2）Citric acid adds suitable quantity of water, after being configured to the citric acid solution that concentration is 2-5%, adds biological powder, stirs at 40-60 DEG C After mixing 0.5-1h, zinc nitrate, silver nitrate are added, after stirring, filter, use distilled water wash filtering residue, to filtrate in neutrality, Filtering residue is added in sodium bicarbonate solution of the concentration for 2-3%, 0.5-3h is stirred at 30-50 DEG C, filtered, use distilled water wash Filtering residue, to filtrate in neutrality, after filtering residue is dried at 50-70 DEG C, obtains final product biological load antibacterial powder standby；
（3）After styrene-acrylic emulsion is mixed with tripolycyanamide, after adding the mixing of biological load antibacterial powder, impregnation liquid is obtained standby；
（4）After Folium Artemisiae Argyi, Folium Isatidiss mix, steam explosion is carried out, explosion water vapour pressure is 0.05-0.3Mpa, blasting time is 1-3s, produces thing and is dried Jing after processed, obtain xeraphium standby；
（5）Mixed straw, tencel fiber and xeraphium by weight；Pulper size degradation is then placed in, add water suitable quantity of water, consolidate Content is the slurry of 4-6%, adds other surplus stocks in addition to impregnation liquid, stirs and continue size degradation and obtain mixed slurry, and Jing is discongested After machine is discongested, then defibrination, after defibrination, gained slurry is sized mixing through adding water, and copies according to conventional paper technology to solid content 3-5% Paper, molding squeezing, to be drying to obtain forming paper standby；
（6）Forming paper is placed in impregnation liquid and impregnates 2-3h, then removes excessive impregnation liquid with pressure roll；It is permanent at 160-200 DEG C Temperature drying Final finishing, obtains final product.
It is an advantage of the invention that：（1）Rationally, intensity is high for inventive formulation, and fire resistant flame retardant is safe, is hardly damaged, adds Ceramic fibre is added, has been effectively increased the intensity of the present invention, ceramic fibre has been a kind of fibrous light refractory material, with weight Gently, the advantages of high temperature resistant, heat stability be good, low thermal conductivity, specific heat are little and mechanical resistant shakes.
（2）The present invention uses impregnation liquid, serves the effect of multistage filtering, compensate for some perforations aperture between filter paper fibre Larger defect, improves the uniformity in hole aperture between filter paper fibre, enhances sieving effect.Add biological load simultaneously Antibacterial can be loaded by antibacterial powder, bio-carrier, slow to discharge, and antibacterial action is strong, lasting effect is good, tool broad spectrum activity and with processing The compatible good advantage of product, various antibacterials, mycete is all had and kill well inhibitory action, to environment without any pollution.Profit With orange peel, durian shell, Cortex Sacchari sinensis as bio-carrier, turn waste into wealth.
（3）The present invention adopts steam explosion technology, and the fiber in plant cell is bondd by lignin, steams with high temperature, high pressure Under vapour effect, cellulose crystallity is improved, and the degree of polymerization declines, hemicellulose fraction degraded, and lignin softens, under horizontal strength of connection Drop, when the material sudden pressure reduction full of steam, the acute expansion of the gas in hole produces " explosion " effect, raw material is torn For fiber fines, obtained fiber slurrying has high yield pulp1, free of contamination feature..
