Moreover, the polishing process of the ceramic tiles is also carried out by adopting a grinding disc mode, and a large amount of fine powder is generated. A large amount of ground powder can be applied to the normal production of foamed ceramics after being subjected to filter pressing, the fine powder has no viscosity due to high-temperature firing, the using amount is controlled to be 50-60 percent (the total amount of the fine powder and the polishing slag of the foamed ceramics), the residual 40 percent of the fine powder can replace river sand to be used as aggregate of the cement-based cementing material, but the additional value is limited.

In view of this, the invention is particularly proposed.

In other embodiments, the self-leveling mortar may be obtained by dry-mixing portland cement, aluminate cement, fine-ground polishing aggregate, and an auxiliary agent; and then adjusting the dry-mixed mortar into a paste shape, printing the paste on the surface of the foamed ceramic by adopting a screen printing mode, adding the dry-mixed mortar into a flatting agent to obtain self-leveling mortar, spraying the self-leveling mortar on the surface of the foamed ceramic, and naturally curing the mortar after uniformly blowing and smearing the mortar to obtain the foamed ceramic surface with better surface effect. Wherein, the silk-screen printing is to print on the surface of the foamed ceramic plate by adopting a 60-80 mesh screen in a silk-screen printing mode. Meanwhile, through the arrangement of printing and spraying, the use amount of mortar can be reduced, and the amount of the mortar entering surface holes is reduced; the printing silk screen can be designed into patterns with certain patterns to form relief-shaped patterns, so that the bare concrete surface relief effect is achieved.
It should be further noted that the surface polishing and the surface decoration are implemented by naturally curing the dry-mixed mortar for 10H, then performing surface polishing, and polishing the surface with 500-mesh and 1000-mesh sand paper to remove surface nails or impurities for facilitating later-stage decoration by other processes.
