Background

In recent years, China has entered the construction and has told the growth period, and the quality requirement for the construction material is higher and higher, so as to ensure that the construction has higher practicability.

At present, the water absorption of domestic bricks is higher than 30%, and when the saturated water in a wall body cannot volatilize, the wall body has a series of problems. Firstly, the outer wall is absolutely waterproof, compact and airtight, and secondly, most of the existing inner wall coatings on the market are in a film shape, compact and airtight.
