Houses in the south of the Yangtze river are mostly built in the south of the river due to the fact that the water content in the air is relatively high throughout the year in the south of the Yangtze river. Therefore, when the wind blows from the south and east, a large amount of humid air enters the room, and the temperature in the room is often lower, so that the moisture in the air is liquefied into water drops on the wall surface and the ground surface of the room. Therefore, the wall surface and the ground are easy to become wet and slippery, people are not easy to walk in a room, mildew is easy to breed, and a lot of inconvenience is brought to healthy home life of people.
Diatomaceous earth is a siliceous rock formed from the remains of silicates of unicellular diatoms organisms. The main mineral component is opal and its variety, which has high chemical stability, and is soluble only in hydrofluoric acid, insoluble in any strong acid, and soluble in alkali. The diatomite has light weight, large specific surface area and high porosity, so the diatomite has stronger activity and adsorption characteristic, and the special physical and chemical properties of the diatomite ensure that the diatomite has wide application. However, the diatomite is mainly developed in a light weight direction when being applied to the ceiling, the strength and the sound absorption performance of the ceiling cannot be achieved, the occasions where the diatomite ceiling is used are limited to a great extent, and the development of the diatomite ceiling is not facilitated.
