Formula and preparation process of self-stretching high-smoothness transparent glaze slip

Abstract

The invention discloses a formula of self-stretching high-smoothness transparent glaze slip in the technical fields of a formula and a preparation process of the self-stretching high-smoothness transparent glaze slip; prepared crystals are good in transparency and relatively smooth in surface, and the defects that a traditional glaze surface is large in roughness, uneven, weak in flushing function and the like can be overcome; the glaze layer of the finished product fired on the basis of the melting fluidity of a frit is in a crystal brick shape, crystal brick bodies are uniformly distributed, the surface feels smooth, pores and ripples are avoided, the finished product is prepared by a production process which is reasonably adjusted in proportion and properly controlled, and aluminum oxide is introduced, so that the initial melting temperature range is wide, and the firing process is more favorably controlled; and crystallization phase and glass phase can be effectively balanced, transparency is improved, argil is introduced into the formula, the bonding strength of a blank glaze can be enhanced, the overall quality of the product is improved, and ceramic ware made of the transparent glaze is high in glossiness and low in lead and cadmium dissolution amount and has the advantages of being attractive in appearance, healthy, environmentally friendly and the like.

Description

technical field [0001] The invention relates to the technical field of transparent glaze paste, in particular to a self-stretching, high-smooth transparent glaze paste formula and a manufacturing process. Background technique [0002] Transparent glaze is a glaze in which the color of the underglaze body and various carvings and colored decorations can be seen through the glaze layer. Colorless and colored clear and transparent glazes, the color of the underglaze body can be seen through the glaze layer, various sculptures and colored decorations, etc. There are many types of transparent glazes, such as lime glazes used on daily-use porcelain and sanitary porcelain, Feldspar glaze and lead-boron glaze used on glazed tiles, etc. In the field of sanitary ceramics, traditional sanitary ceramic sanitary ware adopts opacifying glaze technology to make the ceramic glaze smoother and whiter. The most important opacifying raw material is silicon Zirconium acid, its opacification pr...

Colorless and colored clear and transparent glazes, the color of the underglaze body can be seen through the glaze layer, various sculptures and colored decorations, etc. There are many types of transparent glazes, such as lime glazes used on daily-use porcelain and sanitary porcelain, Feldspar glaze and lead-boron glaze used on glazed tiles, etc. In the field of sanitary ceramics, traditional sanitary ceramic sanitary ware adopts opacifying glaze technology to make the ceramic glaze smoother and whiter. The most important opacifying raw material is silicon Zirconium acid, its opacification principle is that zirconium silicate produces countless bubbles during the firing process, which makes the visually milky white phenomenon, but this milky white gas also leads to large roughness of the glaze surface and uneven glaze surface caused by high porosity , low gloss, which will easily affect the washing function and appearance of sanitary ceramics. Therefore, we propose a self-stretching, high-smooth transparent glaze formula and production process
