Sandstone, as its name implies, is a kind of stone material which can be used as building materials by the polymerization of sand. Its main components are silica and alumina. In nature, it is formed by marine deposits and land deposits in geological changes, which cover the original topography with a large number of sand layers in the process of geological changes, and then heat and pressure. With the development of architectural decoration that pursues environmental protection and health, it advocates a new consumption concept of advocating nature. Sandstone with colorful textures is healthy, environmentally friendly and highly decorative. It is a unique decorative stone and is highly sought after.
Mudstone also has plasticity similar to plastic, which is more suitable for carving and cutting thin plates with a thickness of10 mm. It is generally believed that the slight plasticity of sandstone is due to the molecular connection between SiO2 _ 2 _ 2, but it has not formed caking. The water absorption of sandstone is very high, and some varieties of water almost penetrate into the stone. Sandstone has the characteristics of sound absorption, moisture absorption, fire prevention, matte and so on because of its large porosity in internal structure. Varieties with this characteristic can be decorated in theaters, gymnasiums, restaurants and other public places with sound absorption requirements, and the effect is very ideal, even the sound-absorbing board and wall painting can be omitted.
