Ceramic washbasin production process

Ceramic washbasins and bathroom washbasins are both ceramic products. Now let's take a look at the characteristics of ceramics:

1. High temperature heating at 1280 degrees Celsius makes the product truly fully ceramicized, with the advantages of high temperature resistance, wear resistance, and non-water absorption.

2. Imported special glaze formula, the glaze is smooth and delicate, the surface is wear-resistant, stain-resistant, and easy to clean. 3. Long-term use ensures that it is as good as new.
Now let's take a look at the production process of ceramic washbasins, bathroom washbasins and other ceramic sanitary ware! 1) Ceramic

1)Production Raw Materials

• It is divided into porcelain clay and glaze. The raw materials contained are basically the same, but the raw material ratios are different.
• Its main ingredients: feldspar, quartz, iron oxide, zirconium oxide, aluminum powder, magnesium oxide, and colorants. K20 SiO2 ZnO ZrO2 AL2O3 MgO
• Clay: A kind of clay used to produce pottery and porcelain is referred to as clay.
• Porcelain: A finished product that is completely vitrified into porcelain during high-temperature firing.
• Pottery: finished products that are not completely vitrified and not porcelain during high-temperature firing.
• The difference between porcelain and pottery: raw material formula, product water absorption rate, firing temperature.
• Slurry: raw materials used for molding grouting.
• Glaze: raw materials used for spraying glaze on semi-finished products.
• Production process: ball milling, screening, iron removal, pool storage. Ball milling and screening must meet the national standard of 325 mesh.

2) Mold

• Plaster mold used for molding grouting.
• Material: gypsum powder
• Features: fast water absorption, short solidification time, easy repair, cheap price.
• Grouting times: 80 times-120 times.
• Production process: 3D drawing design, original mold artificial sculpture, mother mold made of resin.
• The mother mold is formed, and the sub-mold is produced through the mother mold for molding grouting.

3) Molding pouring

• Use slurry to form a semi-finished blank in the gypsum mold.
• Each molded product is composed of at least two module models.
• Forming method: single-sided slurry suction, double-sided slurry suction.
• Production process: slurry injection, slurry discharge, demoulding, splicing and drilling, and blank repair.

4) Spraying glaze

• Use glaze to spray evenly on the semi-finished blank.
• Spraying glaze method: robot spraying glaze, manual spraying glaze.

5) Firing

• The semi-finished product sprayed with glaze is formed after high-temperature heating in the kiln.
• Firing shrinkage: no more than 1.15
• Firing time: 13 hours to 15 hours.
• Firing temperature: 1210℃-1290C
• Firing process: preheating zone, firing zone, cooling zone.
• Kiln types: shuttle kiln, tunnel kiln, roller kiln.

6) Inspection

• Slurry: fineness, specific gravity (water content), shrinkage, strength, bending resistance, flow thixotropy.
• Glaze: flow, thixotropy, fineness, specific gravity, color difference, high temperature flow, drying time, body glaze adaptability (to control thermal stability).
• Color difference: glaze is applied to tiles and fired, and compared with the American KOHLER standard color plate, using an imported colorimeter.
• Color: visual inspection.
