Description

Technical Field

[0001] The invention relates to the technical field of ceramic preparation, in particular to a ceramic plate processing and preparation process. Background Art

[0002] Ceramic panels are extremely weather-resistant. Sunlight, rain (even acid rain), and moisture have no effect on the surface and substrate. UV resistance and color stability fully meet the international grayscale level 4-5. Similarly, large or rapid temperature changes will not affect the characteristics and appearance of the material. The reasonable combination of bending strength and elasticity makes ceramic panels have high impact resistance. The dense material surface makes it difficult for dust to adhere, making it easier to clean. Ceramic panels have excellent fire resistance. They will not melt, drip or explode, and can remain stable for a long time. Ceramic panels are easy to maintain, and no paint or protective surface layer is required on the surface and cut edges. Due to the superior characteristics of ceramic panels and their rich colors, they are mainly used for outdoor curtain walls and indoor decoration.

[0003] In order to facilitate mass production and reduce production costs, and to achieve the perfection of hardness, strength and porosity in mass production, a processing and preparation process for ceramic plates is designed. Summary of the invention
