The ceramic product has a glazing process during the production process. The so-called glaze refers to a glaze slurry having a certain depth, that is, a glaze suspended in water, which is sprayed onto the surface of the green body by using compressed air. The green body quickly absorbs the moisture in the wet glaze and forms a relatively hard surface, and a glaze layer having a thickness of 300 to 400 μm is formed on the surface of the fired product. However, many ceramic products have the phenomenon of shrinking glaze when they are released, which is the lack of large area of ​​glaze on the surface of ceramic products. How to prevent the phenomenon of shrinkage during the ceramic making process? Xiaobian's suggestion is mainly in the control of the glazing process. 1. Before spraying the glaze, carefully clean the product to ensure that it is flat and clean; 2. Spraying the green fabric with water before glazing helps to mix the residual dirt and soluble salts on the surface of the blank onto the glaze, but if the blank is already contained within 2 hours before glazing After cleaning the sponge with clean water, there is no need to spray water again; 3. Use clay with a lower soluble salt to keep the model and floor clean. When used repeatedly, remove BaC03; 4. Avoid oil or lubricating oil on the green body. The use of compressed air during the cleaning of the blank before glazing may bring in oil, so the compressed air should be filtered to remove oil; 5. Avoid escaping or scraping off the glaze after spraying the glaze; 6, the use of micro-scale micro-materials, can reduce the rate of glaze moisture penetration into the blank, when the glaze has a large dry shrinkage when the surface of the blank is dry, so it is easy to crack, so the amount of clay added in the glaze should not exceed 5%. The above is a good control of the glazing process in the production process of ceramic products. Only in this way can the surface of the ceramic products that are baked be no longer glazed, of course, if you need to buy daily ceramic products, then if you encounter glaze Phenomenon products, it is recommended that you do not want to buy, it is not only not beautiful, and the production process is not too good.
