Problems solved by technology

However, when conventional glazes are used, substances yet to be dissolved tend to remain in the glaze layer, or the zirconium silicate emulsifier crystallizes to appear on the outermost surface of the glaze layer
Therefore, a glaze layer with a glossy surface and a smooth surface cannot be obtained
At the same time, the viscosity of the glaze has a great influence on whether the melted glaze can be spread into a smooth high-quality glaze on the surface of the body; at the ripening temperature, the viscosity of the glaze is too small, the fluidity is too large, and it is easy to cause Defects of flowing glaze, piled glaze and dry glaze. If the viscosity of the glaze is too high, the fluidity will be poor, which will easily cause defects such as orange glaze, pinholes, rough glaze surface, and poor gloss.

Abstract

The invention relates to a glaze formula and a preparation process thereof. According to the invention, feldspar, quartz, calcined talc, alumina, calcium carbonate, zirconium silicate, porcelain powder and kaolin of Longyan are ground and mixed, a glaze layer fired by the glaze formula has characteristics of bright glaze layer, uniform glaze thickness, wear resistance, and impact resistance, and can prevent the glaze from being damaged during the collision, and the firing qualification rate is more than 97%.

Description

technical field [0001] The invention relates to a glaze formula and a preparation process thereof, belonging to the technical field of ceramics. Background technique [0002] Ceramic products are widely used in our country, and the technology for preparing ceramics is also very mature. There is a layer of glaze on the outermost part of ceramics. One is to make the appearance of ceramic products more beautiful, and the other is to increase its tolerance. Usually, the glaze is applied to the porcelain to form a layer of glaze, which is then fired to apply the glaze. Therefore, since the glaze layer has anti-pollution and makes the porcelain have a beautiful appearance, it is widely used in ceramic sanitary ware for toilets and bathrooms as well as ordinary porcelain. Although the amount of material used in the general glaze layer is much smaller than that of the blank, the quality of the glaze directly affects the performance and grade of the product, giving people an intuit...
