What is the production process of ceramic sanitary ware?

The raw materials for ceramic production are divided into porcelain clay and glaze, both of which contain basically the same raw materials, but the proportion of raw materials is different. Its main components: feldspar, timing, iron oxide, zirconia, aluminum powder, magnesium oxide and pigment. Clay: A kind of clay used to produce pottery and porcelain. Porcelain: a finished product that is completely vitrified into porcelain during high-temperature firing. Pottery: a finished product that is not completely vitrified during high-temperature firing. The difference between porcelain and pottery: raw material formula, product water absorption, firing temperature. Slurry: raw materials used for molding grouting. Glaze: raw materials used for glaze spraying of semi-finished products Production technology: ball milling, sieving, iron removal and pool storage. Ball milling and sieving must meet the national standard of 325 mesh. Gypsum mould for molding grouting. Material: Gypsum powder features: fast water absorption, short solidification time, convenient repair and low price. Grouting times: 80 times-120 times. Production process: 3D drawing design, original model artificial sculpture, main model made of resin.

A master mold is formed, and a sub mold is produced by the master mold for molding and grouting. The slurry is put into a gypsum mold to form a semi-finished blank. For each molded product, at least two modular models are combined. Forming methods: single-sided pulp suction and double-sided pulp suction. Production technology: grouting, discharging, demoulding, splicing and punching, trimming. Spray glaze evenly on the semi-finished blank. Glaze spraying method: manual spraying, manual spraying. Glazed semi-finished products are products formed after high temperature heating in kiln. Sintering shrinkage: no more than 1. 15 sintering time: 13 hours-15 hours. Sintering temperature:1210℃-1290℃ sintering process: preheating zone, sintering zone and cooling zone. Kiln types: shuttle kiln, tunnel kiln and roller kiln. Mud: fineness, specific gravity (water content), shrinkage, strength, bending resistance and rheology.
