As we all know, the raw material of diatom mud is mainly diatomite, which can breathe humidity regulation, purify air, fire prevention and flame retardant, and has artistic effect. It has soft color and long service life. It is a magical inorganic mineral material, but diatomite is not all in diatom mud. Because diatomite has many pores and soft texture, but it is not a viscous mineral material, when it is used for wall materials, when the amount is too large, it becomes a difficult problem to go to the wall and maintain the bond strength. Therefore, the magical diatomite also needs the help of cementitious materials on the wall in order to realize her sacred mission of adsorbing indoor air pollution.

As an inorganic material, diatomite is natural and environmentally friendly, and it is a functional material for removing aldehydes. Therefore, its own materials will not actively choose materials containing formaldehyde. Therefore, chemical adhesive is not suitable for diatomite wall, but inorganic cementitious material is generally used. So what is inorganic cementitious material? Generally speaking, it is a mineral material that does not contain carbon and has a certain viscosity. The earliest inorganic cementitious material used by human beings should be natural clay, that is, the material used in clay house. However, clay houses do not have water stability, that is, they will dissolve into mud and lose bonding strength when encountering water. Therefore, more and more clay houses have been transformed into current cement concrete houses, and cement concrete is a kind of building material mixed with cement and sand, in which cement is an inorganic cementitious material with better hydraulic hardness, It is an inorganic cementitious material with the highest bond strength among modern building materials.

In addition, inorganic cementitious materials include lime, white cement, gypsum and other materials. These are natural inorganic mineral materials. They are non-toxic, harmless, formaldehyde free and have a certain viscosity. They are used in the internal and external walls of buildings like cement. At present, diatom mud is mainly selected from lime, white cement, gypsum and other materials. However, some diatom mud speculators add inorganic cementitious materials as main materials, As a result, the "diatom coating" called "diatom mud" by "adding a handful of diatomite" is flooded, confusing the public and affecting the judgment of consumers. In fact, the addition amount of diatomite in diatom mud is in a certain proportion. According to the regulations, the addition amount should be at least 15%. If from the perspective of detection, the addition amount should be at least 10%.
