Description

A kind of high, Gao Bai, high-strength egg-shell ceramic veneer
Technical field
The invention belongs to inorganic non-metallic materials（Ceramics）Field, and in particular to a kind of high, Gao Bai, high-strength egg-shell ceramic veneer.
Background technique
Eggshell porcelain is commonly called as eggshell porcelain, world-famous with " thin as a piece of paper, white as a jade, bright such as mirror, sound such as single sonorous stone ".Eggshell porcelain is with material It is light be full of, the features such as translucency is good, exquisite in texture, shows very big application prospect on Ceramic Market.Egg-shell ceramic veneer is all at present Be using it is artificial it is hand-made form, thickness is typically greater than 1mm, and there are great work intensity, working hour it is long, it is damaged it is more, The nonstandard equal great number of issues of product specification.In the prior art if egg-shell ceramic veneer is made thinner, it is easy to appear porcelain plate base The problems such as body uneven surface, rupture, wing angle, deformation, this not only adds production costs, and limit the extensive of egg-shell ceramic veneer Using.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of simple process, height low in cost, best in quality thoroughly, high White, high-strength egg-shell ceramic veneer.
The present invention is achieved by the following technical programs：A kind of high, Gao Bai, high-strength egg-shell ceramic veneer, it is characterised in that： Using natural mineral raw and industrial chemicals, the weight percent formed according to material：Longyan kaolin 30 ~ 35%, quartz 10 ~ 12%, aluminium oxide 5 ~ 8%, feldspar 30 ~ 35%, talcum 4 ~ 6%, calcite 1%, potassium feldspar 2 ~ 5%, albite 1 ~ 2%, bone meal 8%, Yttrium oxide 3 ~ 5%, the additional porcelain powder 4% after elutriation, ingredient, ball milling, then through except iron, filtering, mud conditioning, molding, primary drying, Repaired biscuit, biscuiting, refine, glazing, redrying, glaze firing process obtain egg-shell ceramic veneer product.
The egg-shell ceramic veneer product surface can be used new color or powder enamel on glaze and carry out painted decoration, and color roasting temperature is after decoration 700~800℃。
The molding procedure uses hot high pressure injection forming.
Slurry temperature in the hot high pressure injection forming is 40 ~ 45 DEG C, and pressure is 0.8 ~ 1.2MPA.
After the repaired biscuit process green body with a thickness of 1 millimeter, after the glazing process glazed thickness be 0.5 millimeter, it is described Feed particles fineness was 600 meshes after ball milling process, and tailing over is 0.5%, and the mud conditioning process is vacuumize process.
The base is calcined before use with raw material, and calcination temperature is 800 DEG C.
Carcass moisture content is lower than 1.5% after the redrying process.
The calcining system of the biscuiting process is：800 DEG C are warming up to from room temperature by the rate of 3 DEG C/min.
It is described glaze firing process calcining system be：1320 DEG C are warming up to from room temperature by the rate of 3 DEG C/min, then presses 20 DEG C/rate of min is cooled to 1160 DEG C, 1320 DEG C finally are warming up to by the rate of 1 DEG C/min, and keep the temperature 30min.
The porcelain powder be egg-shell ceramic veneer green body acquisition is crushed after biscuiting, grain fineness was 600 meshes, tail over for 0.5%。
The glaze that the glazing process uses is the white 6211 type clear frit of height of rainbow glaze factory of Jindezhen City of Jiangxi Province production, Glazing mode is leaching glaze.
Since the raw material for preparing of conventional blanks formula is not able to satisfy the egg-shell ceramic veneer requirement, therefore introduced in body recipe Bone meal, porcelain powder, yttrium oxide, then by carrying out fine ball milling to base materials, and slip casting is increased at the pressure of base, so that blank structure Finer and close, the later period, various raw materials reacted to each other in high temperature, and can obtain more transparent, porcelain after combining special calcining system The finer and close egg-shell ceramic veneer of tire, transparency, resistance to fracture are higher, so that the egg-shell ceramic veneer made is more for good Service performance.
The present invention increases green body using the solid hot injection formation technology of high pressure by improving egg-shell ceramic veneer blank formulation Intensity, the breakage and deformation for reducing green body improve production efficiency and product quality, and product qualification rate less than 40% by improving To 80% or more, and the whiteness of product, transparency, hardness of glaze surface, flatness are all significantly increased, to change egg-shell ceramic veneer At present can only small lot production status, realize the mass production of product.High thoroughly, Gao Bai, high-strength characteristic according to this product, Independent band backlight artistic product is made in combination with backlight, product is made, household, office, indoor spaces is suitble to make decoration atmosphere Lampshade uses.The egg-shell ceramic veneer that the present invention is protected has expanded the practicability and application field of porcelain plate, therefore has wide answer Use prospect.
