What kind of function does precipitated barium sulfate have in the rubber industry

Barium sulfate mainly exists in the form of barite ore in nature, and its molecular formula is BaSO4. Pure barium sulfate is white and shiny. Due to the influence of impurities and mixed substances, it is often gray, light red, light yellow, etc., and the crystallization is quite good. The barium sulfate can also appear as transparent crystals. The hardness of barium sulfate is (Mohs) and the specific gravity is Barium sulfate is chemically stable, insoluble in water, non-magnetic and toxic. Radiation-proof cement, mortar and concrete use barium sulfate to absorb X-rays. The produced barium sulfate is used to make barium cement, barium mortar and barium concrete, which are used to replace metal lead plate nuclear reactors and build scientific research and hospitals to prevent X-rays. buildings.

Barium sulfate for rubber is used in the rubber industry. Many products below 500 mesh can be used in rubber products as fillers, reducing costs, mobilizing product hardness, acid and alkali resistance and water resistance, etc., and have good reinforcement for natural rubber and synthetic rubber. utility. Used in paper industry - high-precision barite powder can be used as filler and coating filler for white board paper and copper round paper to adjust whiteness and surface coverage. Used in coatings and raw lacquers—it can be used as fillers for raw lacquers and coatings to replace raw materials with higher unit prices such as barium sulfate, lithopone, titanium dioxide, and active silicon dioxide for rubber. Settled well. Used in the plastic industry—it can be used as a filler for plastic ABS raw materials to make the product shiny and bright, and at the same time, it can also mobilize the intensity, stiffness and wear resistance of the product.

Barium sulfate should be stored in a cool, ventilated warehouse, away from fire and heat sources. It should be stored separately from flammable (combustible) materials and reducing agents, and should not be stored together. Storage areas should be provided with suitable materials to contain spills. When storing barium sulfate, avoid contact with oxides, almost insoluble in water, ethanol and acid. Soluble in hot concentrated sulfuric acid, easy to agglomerate when dry. Staff should be well protected, and the workplace should have good ventilation conditions. In case of accidental contact with skin and eyes, wash immediately with running water.
