Problems solved by technology

The product is used as a decorative material for the wall of a building. It is used in different places according to different needs. There are also some functional ceramic tiles. For example, the patent application CN103553564A discloses a ceramic tile with absorbing and releasing functions made of diatomite as the main component. The method of ceramic tiles, the diatomite tiles produced have the function of absorbing and releasing. Ordinary tiles basically only have a decorative function, and have almost no effect on improving the indoor environment. The reason makes its adsorption effect greatly weakened. The reasons are as follows: Diatomite contains a large number of micropores, which have the function of adjusting humidity before firing. Diatomite is easy to be sealed during the production process. The gaps of diatoms are easily destroyed, and the micropores are not easy to connect, forming closed pores, which reduces the adsorption, fluidity and release properties
[0006] In China, breathing bricks made of sepiolite, zeolite, and medical stone are also used. Because they have a large number of micropores, they have a certain adsorption effect, but they are not viscous and cannot be solidified. Adding viscous materials to form them will cause micropore blockage. If firing is carried out because there is a large amount of calcium, magnesium, iron, potassium, sodium, the temperature rises, and the microporous structure is lost
Due to the high iron content of sepiolite, zeolite and medical stone, the color of the body is not easy to control, and the grade of fired bricks is also low.
Natural sepiolite, zeolite, and medical stone are relatively rare raw materials, so they are not suitable for making breathing bricks
