Description
Technical Field
The utility model belongs to the technical field of composite boards, and particularly relates to a composite rock board and wallboard structure.
Background
The rock plate building material has the characteristics of large specification, strong plasticity, various colors, high temperature resistance, abrasion resistance, seepage prevention, acid and alkali resistance, zero formaldehyde, environmental protection, health and the like, and is widely applied to the field of buildings by means of the characteristics. In the aspect of the wallboard installation, use the slate wallboard to carry out wall decoration, make the whole wall outward appearance of building beautifully atmospheric, the various high temperature resistant of design, wear-resisting scrape, the prevention of seepage passes through, acid and alkali-resistance, zero formaldehyde, characteristics such as environmental protection health, consequently use the slate wallboard to carry out wall decoration more and more popular in the modern building.
At present, the wallboard mounting mode on the wall body is generally two: wet pasting and dry hanging. In the wet pasting method, a large amount of dust can be generated due to the use of pasting mortar, the environment-friendly requirement advocated in the building field in China in recent years is not met, the wet pasting method is used for a long time, and alkaline substances in the mortar are easy to penetrate to the surface of the wallboard, so that the appearance of the wall body is influenced. Compared with the wet pasting method, the dry hanging method has the characteristics of avoiding surface pollution and discoloration, preventing alkali, keeping the color and luster of the stone, protecting the environment and the like.
