Architectural ceramics are widely used in the field of architectural decoration, and the quality of the ceramic glaze layer plays a vital role in the aesthetics and durability of architectural ceramics. In the preparation and use of architectural ceramic glaze, the foam problem is a factor that cannot be ignored. The reasonable application of defoamers for architectural ceramic glaze can effectively solve this problem. In the preparation process of architectural ceramic glaze, foam is easily generated due to various reasons such as stirring and the use of additives. These foams will have many negative effects on the ceramic glaze. Foam will form depressions on the surface of the glaze layer. When ceramic products are fired after glazing, foam will leave bubble holes in the glaze layer, which will destroy the flatness and glossiness of the glaze layer.
In the preparation process of architectural ceramic glaze, foam may be generated from raw material mixing to glazing. The defoamer for architectural ceramic glaze can quickly eliminate the generated foam and control the re-generation of foam for a long time. In addition, it is well compatible with various minerals, fluxes, colorants and other components in the glaze, and can also stably exert its defoaming effect under different pH environments.
Defoamers for architectural ceramic glazes are an indispensable and important part in the production process of architectural ceramics. They can effectively solve the foam problem in the preparation and use of architectural ceramic glazes and improve the appearance quality and performance of the glaze layer. With the continuous development of the architectural ceramics industry, the performance requirements for defoamers for architectural ceramic glazes will continue to increase. Future research and development will be committed to finding more stable and environmentally friendly defoamers for architectural ceramic glazes.
