Due to its solid structure, stable composition, fine white color and non-toxicity, diatomite has become a novel and excellent filling material widely used in rubber, plastic, paint, soap making, pharmaceutical and other industrial sectors. It can improve the stability, elasticity and dispersity of the product, so as to improve the strength, wear resistance and acid resistance of the product. For example, in the pharmaceutical industry, it can be used as “dimethoate” powder filler and vitamin B filler; In paper industry, it can overcome resin barrier, improve uniformity and filtration after adding it into pulp. In the rubber industry, it can make white shoes, pink bicycle tires; In the plastic industry, it can be used as filler to produce acid resistance, oil resistance, aging resistance of high strength plastic pipe and plate, its performance is much more than PVC products; In synthetic detergent, it is used as auxiliary agent instead of sodium tripolyphosphate, and the synthetic detergent made has the excellent characteristics of low foam, high efficiency and no pollution.
Natural diatomite not only contains certain chemical composition, but also has good porous structure characteristics, such as good specific surface area, pore volume and pore size distribution, so it becomes an excellent carrier of vanadium catalyst for producing sulfuric acid. High quality diatomite carrier can increase the activity of vanadium catalyst, improve the thermal stability, improve the strength and prolong the service life. Diatomite is also an indispensable cement mixing material. The diatomite powder is roasted at 800 ~ 1000℃ and mixed with Portland cement by 4:1 by weight to become heat-resistant mixing material. Special types of cement made from diatomite can be used as low specific weight cement in oil drilling, or in fractured and porous formations to prevent loss of cement slurry and prevent the cement slurry from being too heavy to block low-pressure oil and gas zones.
