Abstract
The invention proposes a glazing process method for an isostatic compaction ceramic rough body. The method comprises the following steps that: firstly a high polymer solution layer is formed on the ceramic rough body having undergone bisque firing at a temperature of between 900 and 1000 DEG C through impregnation, and a multi-orifice high polymer micropore film formed on the surface of the dried rough body can serve as a screen to prevent solid particles in a slurry from entering the pores of the rough body without impacting the slurry absorption performance of the rough body; then a layer of base coat and overglaze is applied to the rough body to obtain a smooth and flat glaze after high-temperature burning. The method solves the problem of easy production of a glaze hole defect lying in isostatic compaction ceramic products.
Description
Technical field
The invention belongs to the traditional ceramics manufacturing technology, be specifically related to a kind of glazing process that is used for isostatic compaction of ceramic base substrate
Background technology
When adopting isostatic pressing method to prepare ceramic product, in order to improve the flowability of powder, blank must pass through mist projection granulating, and final resulting blank is the spheric coacervate, and its particle size is bigger.This blank is through behind the isostatic pressing, and compacting fully between the spheroidal particle causes the coarse injustice of base substrate of moulding, and there is a large amount of pits in the surface.During glazing, glaze slip is easy to penetrate in the pit that forms between spheroidal particle, very easily makes glaze a lot of small holes occur on this base substrate.Though these glaze small holes size in sintering process reduces to some extent, can not make up fully, cause ceramic product still to be covered with a large amount of pin holes burning till the back glaze, glaze glossiness variation has a strong impact on the quality and the class of ceramic product.Adopt traditional glazing process,,, still can't fundamentally solve the difficult problem of the ceramic product glaze quality difference of isostatic pressing though glaze quality is made moderate progress by improving glaze formula.
Summary of the invention
The objective of the invention is to propose a kind of new glazing process that is used for isostatic compaction of ceramic base substrate, can solve the difficult problem that the isostatic pressing ceramic product very easily produces the glaze needle pore defect effectively.
A kind of glazing process that is used for isostatic compaction of ceramic base substrate that the present invention proposes is characterized in that: earlier through 900 ℃～1000 ℃ unglazed ceramic body surface impregnation high molecular polymer aqueous solution, execute ground-coat enamel after the drying, execute cover-coat enamel after the drying again.Described high molecular polymer is so long as can get final product at the high molecular polymer that billet surface forms one deck micropore organic film.
Above-mentioned high molecular polymer preferably carboxymethyl cellulose sodium (CMC) or polyvinyl alcohol (PVA), the preferred 0.1wt%～2.0wt% of base substrate impregnation concentration; The fineness requirement of described ground-coat enamel and cover-coat enamel is preferably: ground-coat enamel was 100 mesh sieve screen over-size 0.2wt%～0.5wt%, and cover-coat enamel was 250 mesh sieve screen over-size 0.02wt%～0.05wt%.
Key problem in technology of the present invention and innovation are at first at dipping one deck macromolecule polymer solution on 900 ℃～1000 ℃ unglazed ceramic bodies, dry back billet surface just forms one deck high molecular polymer microporous membrane, it plays the effect of screen cloth, can stop the solid particulate in the glaze slip to enter into the base substrate hole, thereby effectively avoid glaze to produce small holes.Can form the glaze layer of even compact when making glazing, burn till the back and just can obtain the smooth smooth ceramic product of glaze.Because the high molecular polymer film is a microporous membrane, it can be permeable, so it can not influence the suction slurry performance of base substrate again.
Another innovation part of the present invention is the thicker ground-coat enamel of first last layer particle before the glaze in the above, can prevent better that like this glaze slip fine particle from infiltrating in the base substrate hole, guarantee cover-coat enamel surface even compact and small holes can not occur, help burning the back and form smooth smooth glaze.
