Product introduction:
The color of diatomite is white, grayish white, gray, light gray, light grayish brown, light yellow, etc. High chemical stability, porous, high melting point, large specific surface area, large porosity, strong adsorption, insoluble in hydrochloric acid, easily soluble in alkali, water absorption is 2 ~ 4 times its own volume, and has many excellent properties such as relatively incompressible, soft, sound insulation, wear resistance, heat resistance and so on. Diatomite has the advantages of large porosity, strong adsorption, small bulk density, high melting point, sound absorption and stable chemical properties. It is widely used in light industry, chemical industry, building materials and other fields. As a filler for rubber, diatomite can obviously enhance the rigidity and hardness of products, improve the heat resistance, wear resistance and aging resistance of products, and greatly reduce the cost.
Main uses in rubber industry:
① rubber products
② rubber silica gel products
③ precision rubber products
④ rubber pipe
⑤ rubber rolling
⑥ V-belt and conveyor belt
⑦ fillers in various rubber products such as automobile footmats
