Background
The surface of the electric porcelain is usually coated with electric porcelain glaze, wherein the electric porcelain glaze is glaze applied to the surface of a blank of the electric porcelain product, and the coating of the glaze can improve the electrical property, mechanical strength and chemical stability of the electric porcelain, and can make the surface of the porcelain smooth and beautiful and be convenient for cleaning. With the rapid development of electric power utilities, the voltage class is continuously improved, the voltage class is widely distributed between 110KV and 1000KV, and the types of correspondingly used high-voltage and ultrahigh-voltage electric porcelain are various, but various insulators are usually made of different types of electric porcelain blanks (high-grade blanks and low-grade blanks), the structural compositions of different electric porcelain products are different, especially the chemical compositions of the insulators are greatly different, and the requirements on the matching performance of glaze coated on the surfaces of the electric porcelain are higher and higher.
Brown glaze is the most common glaze on current electric porcelain, and most insulators are brown, so that the product has a single color, the requirements of different customers cannot be met, and the competitiveness of the company product is reduced. Glaze materials with other colors are available on the market at present, but the bonding property of the glaze materials and the electric porcelain blank body is poor, and the requirements of China on the indexes such as glazing strength, porcelain bending strength and insulator breakdown rate cannot be met.
Disclosure of Invention
The invention aims to provide a yellow glaze for electric porcelain and a processing method thereof, which aim to solve the problem that the existing glaze product is generally brown glaze and has single color.
In order to achieve the purpose, the scheme of the invention is as follows: the yellow glaze for the electric porcelain comprises the following raw materials in parts by weight: 26-31 parts of potash feldspar, 4-9 parts of albite, 4-8 parts of ball clay, 19-23 parts of hard kaolin, 10-14 parts of calcined talc, 5-9 parts of limestone, 21-26 parts of quartz powder, 1.5-3 parts of barium carbonate and 6-10 parts of yellow chromophore; the yellow glaze comprises the following chemical components in percentage by mass: SiO 22 63-66.5％、AI2O3 14-16％、Fe2O3 0-0.8％、 CaO 3-4％、MgO 3-4％、K2O 2.2-3.4％、Na21-2% of O, 1-2.4% of BaO and 6-7% of loss on ignition.
The working principle and the beneficial effects of the scheme are as follows:
1. the chemical composition and amount of glaze have a crucial influence on the quality of glaze, such as AI2O3Can influence glazing strength, the content of MgO and CaO influences the elasticity of the formula, and SiO2Can play the role of a skeletonAnd the expansion coefficient of the glaze is reduced. The scheme reasonably controls the dosage of various chemical components, obviously improves the elasticity of the yellow glaze material, promotes the generation of the intermediate layer of the blank glaze, is beneficial to the firm combination of the blank glaze, improves the mechanical strength and the thermal stability of the glaze, reduces the thermal expansion coefficient of the glaze and ensures that the glaze is in a good compressive stress state.
2. After the yellow glaze and the blank body are made into porcelain, the electric porcelain has a smooth and bright surface, is fine and smooth and is bright yellow, and can well meet the requirements of customers on the yellow electric porcelain. The yellow glaze material can be well combined with the blank body, after the ceramic is formed, a good middle layer can be generated between the glaze and the blank body, the performance of the ceramic can be greatly improved (the strength of the ceramic is improved by more than 22%), the design purpose is achieved by grinding the yellow glaze material, and the technical and industrial standards of a company can be well met.
3. The albite and the potassium feldspar are mainly used for introducing SiO into the formula2、Al2O3、K2O、Na2O, formula K2O、Na2O is mainly provided by these two species. The two substances are used as strong flux in the glaze, can reduce the melting temperature of the glaze, has good capability of dissolving other substances, has a wider melting temperature range, and can reduce the high-temperature viscosity of the glaze and increase the brightness of the glaze. However, the addition of the two substances can reduce the chemical stability of the glaze to a certain extent and increase the expansion coefficient of the glaze. Barium carbonate mainly introduces BaO for the formulation, can improve the brightness after porcelain is formed to new formulation, improve the stability of the glaze; BaO also forms eutectic compounds with other metal oxides, can reduce the expansion coefficient and viscosity of the glaze and improve the high-temperature fluidity of the glaze. However, when the dosage of BaO is too much, the glazing strength can be reduced, and the glazing strength is ensured while the stability of the glaze is improved by reasonably controlling the dosage of barium carbonate. In the scheme, the Hunan high-potassium low-sodium feldspar, the Hunan high-sodium low-potassium feldspar and the barium carbonate are matched together, so that the prepared glaze has good comprehensive performance.
5. The use amounts of the calcined talc and the limestone are controlled, and the quantitative calcined talc and the limestone are matched, so that the elasticity of the formula can be obviously improved, the generation of a blank glaze interlayer is promoted, the bonding effect of the blank glaze is increased, and the hardness, the stability, the mechanical strength and the thermal stability of the glaze are improved.

3) drying the glazed blank at 50-60 deg.C for 4-5 hr;
4) putting the glazed blank into a kiln for burning;
5) the blank is sintered in the sintering temperature range, and the maximum sintering temperature is 1250-.
Before glazing, the sponge is dipped in water to remove dust on the surface of the blank and supply certain water to the blank at the same time, so that the blank is prevented from absorbing water in the glaze slurry too much to affect glazing. The glaze soaking time, the drying temperature and the firing temperature are controlled, so that the yellow glaze material can be fully contacted and combined with the blank, the porcelain forming effect is ensured, and the high porcelain performance is improved.
