bentonite clay powder is a non-metallic mineral with montmorillonite as the main mineral component. The structure of montmorillonite is a 2:1 type crystal structure composed of two silicon-oxygen tetrahedrons and a layer of aluminum-oxygen octahedrons. There are certain cations in the layered structure, such as Cu, Mg, Na, K, etc., and the interaction of these cations with the montmorillonite unit cell is very unstable, and it is easy to be exchanged by other cations, so it has good ion exchange. Foreign countries have been applied in more than 100 departments in 24 areas of industrial and agricultural production, and there are more than 300 products, so people call it "universal soil."
1. Adding bentonite clay powder to the ceramic process production increases the plasticity and strength of the embryo body or glaze, greatly increases the lubricating effect, and is beneficial to ball milling. In addition, the suspension and stability are greatly enhanced, the porcelain is delicate, the color tone is soft, and the glaze The machine is smooth, with good light transmittance, anti-collision, and has a certain degree of mechanical strength.
2. In the drilling and piling construction, bentonite clay powder has good suspension, thixotropy, low filter loss, good slurry-making performance, convenient preparation, easy adjustment of the specific gravity of drilling fluid, etc. It is an indispensable ideal foundation for deep well and offshore drilling engineering material.
