Abstract
The invention belongs to the technical field of electric ceramic and particularly relates to glaze of an ash glaze product in an electric ceramic dry-process molding technology. The glaze is characterized in that the glaze is prepared by using the following raw materials in percent by weight: 12-18 percent of quartz, 6-12 percent of wollastonite, 20-30 percent of feldspar, 10-15 percent of zirconium silicate, 5-8 percent of Longyan clay, 8-15 percent of Zhangcun clay, 10-16 percent of mature Datong clay, 10-15 percent of calcined talcum powder, 2-5 percent of barium carbonate and 0.2-0.5 percent of exterior color adding agent. The glaze provided by the invention has the advantages that the glaze an be used for producing ash glaze through dry-process molding, the covering power of the glaze after sintering is good and chromatic aberration does not exist; and the glaze is smooth and flat, the gloss is good, the product strength is high and the blank space in ash glaze production through the dry-process molding in China is filled.
Description
Technical field
The invention belongs to the electroceramics technical field, be specifically related to the glaze of ash glaze product in a kind of electroceramics dry-press process technology.
Background technology
Mostly traditional electrical enamel is brown glaze, and used toner plays fluxing action in prescription, has reduced the high temperature viscosity of glaze, becomes more readily available smooth, smooth glaze.And being mostly ash glaze at European glaze for electric porcelain, ash glaze is a zirconium opaque glaze, because the introducing of zirconium silicate has increased the high temperature viscosity of glaze, has influenced the temperature flowing property of glaze, is prone to the tangerine glaze and contracts the glaze defective.
Common electroceramics ash glaze product is to adopt wet production, and glazing techniques is to adopt to soak glaze or water glaze, and glaze layer thickness ratio is easier to guarantee uniformity, can avoid the defective of bringing in uneven thickness, and the performance of glaze is prone to satisfy this technology.And be that wet moulding can't be produced for the ash glaze product of voltage levels; Must adopt dry-press process, the glazing techniques of dry-press process adopts manual glaze spraying basically, and the glaze layer thickness of manual glaze spraying is difficult to guarantee uniformity; The position that the glaze layer is thin is prone to jaundice, and aberration is arranged; The position of glaze bed thickness is prone to the glaze that contracts.This has just determined the ash glaze performance of dry-press process must satisfy enough opacifying powers (being high opacity) and higher temperature flowing property simultaneously.
Summary of the invention
The glaze that the purpose of this invention is to provide ash glaze product in a kind of electroceramics dry-press process technology, this can satisfy enough opacifying powers simultaneously and obtain glaze for electric porcelain smooth, smooth, that possess sufficient intensity.
The glaze of ash glaze product in a kind of electroceramics dry-press process technology of the present invention; Formulated by following raw materials by weight percent: quartzy 12-18%, wollastonite 6-12%, feldspar 20-30%, zirconium silicate 10-15%, Longyan clay 5-8%, chapter village soil 8-15%, the soil 10-16% of ripe Datong District, ripe talcum powder 10-15% and barium carbonate 2-5% add toner 0.2-0.5%.
Quartz is an indispensable raw material in the glaze, and staple is SiO
2After adding quartz, melt temperature and viscosity raising are given glaze glass high firmness, wear-resisting, HS and good chemicalstability.
Zirconium silicate mainly acts on the opacity that provides glaze.
Longyan clay belongs to a kind of viscosity plasticity kaolin preferably, and removing provides required SiO in the prescription
2, Al
2O
3Outward, an amount of suspension and the viscosity that glaze slip is provided of adding guarantees the glaze slip stable performance when glazing, be difficult for deposition, simultaneously because viscosity is big, make the glaze layer can with the base substrate combine well, guarantee that the glaze layer is incrust.
The earth removal of chapter village provides required SiO in the prescription
2, Al
2O
3Required flux component K in the prescription can also be provided outward,
2O.
Ripe Datong District soil mainly provides required SiO in the prescription
2, Al
2O
3Composition.
Feldspar, wollastonite, ripe talcum powder, barium carbonate are as flux component; Be to be used for guaranteeing that glaze has enough temperature flowing property when high temperature; Suitable ratio is to guarantee good fluidity, unlikely again initial melting temperature low excessively (initial melting temperature is crossed the low opacity that can cause and reduced the opacifying power variation).
Reasonably combined through various raw materials guaranteed needed suspension of manual glaze spraying and flowability under the glaze slip normal temperature, and the temperature flowing property that can satisfy glaze simultaneously again is good, and the glaze that neither can contract, unlikely again initial melting temperature are crossed the low milkiness property that influences.
The preparation method gets final product according to traditional glaze preparation method implementation route, and step is following usually: the batching-ball milling-deironing of sieving-old-for use.
The suitable firing range of electroceramics ash glaze of the present invention is 1240～1280 ℃.
The invention has the advantages that: according to the glaze that prescription of the present invention makes, can adopt dry-press process to produce ash glaze, the glaze opacifying power is good after burning till, no color differnece; Glaze is smooth, smooth, good luster, product strength high, has filled up the blank that domestic dry-press process is produced ash glaze.
