30-degree soft polishing process applied to rock board surface layer

Abstract

The invention discloses a 30-degree soft polishing process applied to a rock board surface layer, which comprises the following steps: carrying out primary drying on a green brick pressed by a press to remove free water in the green brick, controlling the moisture content in the green brick to be less than 0.7% of the total mass of the green brick, spraying water mist on the surface of the green brick after the green brick is taken out of a drying kiln, spraying ground coat on the surface of the green brick, and carrying out pattern printing using an ink jet printing machine; drying in a drying kiln, spraying and polishing glaze in sequence, drying in the drying kiln for the second time, putting an obtained product into a firing kiln, firing at the high temperature of 1196 to 1205 DEG C for 60 to 70 minutes, performing rough polishing, medium polishing, fine polishing and soft polishing in sequence, and finally, detecting to apply the qualified rock plate to furniture assembly, house decoration and the like. On the premise that the cost is reduced through a specific treatment method, the surface of the rock plate is polished evenly, the acid and alkali resistance strength is high,the antifouling property of the surface is excellent, and the surface touch hand feeling is soft.

Description

technical field [0001] The invention specifically relates to a 30-degree soft polishing process applied to rock slab surfaces. Background technique [0002] Modern architecture and decoration industry are using more and more imitation natural stone bricks, and the requirements for imitation natural stone bricks are becoming more and more wild. Various types of imitation natural stone bricks are also emerging in large numbers. The porcelain polished bricks currently on the market All of them are produced by "dream fabric", "multi-tube fabric" and "micro-powder multiple fabric". [0003] The disadvantage of the 30-degree soft polishing process currently applied to the surface layer of rock slabs lies in the sequence change of the existing bottom glaze, pattern ink, and glaze polishing, as well as the production by spraying, which leads to the impact of subsequent processing on the rock slab, making the rock slab surface There are differences in the polishing effect and color ...

[0003] The disadvantage of the 30-degree soft polishing process currently applied to the surface layer of rock slabs lies in the sequence change of the existing bottom glaze, pattern ink, and glaze polishing, as well as the production by spraying, which leads to the impact of subsequent processing on the rock slab, making the rock slab surface There are differences in the polishing effect and color level on the surface, and the product application is easy to hide dirt during use, which is inconvenient for hygiene
