Explanation

Using natural raw mineral material and some chemical raw materials in proportion, it is a shiny glass layer that melts under high temperature and covers the surface of green body. The preparation method is to mix raw mineral material (such as feldspar, caldte, quartze, talc, kaolin, etc.) and chemical raw materials (such as ZnO, BaCO3, etc., and some water-soluble raw materials such as KN03, Na2O3, etc. can be made into frits first) in a certain proportion, and then fine grind them into slurry, apply them to the green body by dipping, spraying, brushing, swinging, dipping, leaching, etc., and then melt them at high temperature. The layer is mainly composed of glass phase, with a small amount of crystal and bubbles. It can make ceramics products watertight, smooth and not easy to stain, and to a certain extent, it can improve the mechanical strength, electrical performance and thermal stability of products. Color sleeves also have aesthetic and decorative functions. According to composition, it can be divided into lime sleeve, lime alkali, feldspar sleeve, lead sleeve, lead boron, boron, salt, soil, etc; According to the appearance, it can be divided into transparent, opaque, color sleeve, crystal, semi gloss, matte, broken grain, etc. When some of the raw materials in the material are frits, they are called frit sleeves; No frit is called raw material. It can also be divided into high temperature, medium temperature and low temperature according to the melting temperature of the sleeve
