The Universal Application of Precipitated Barium Sulfate in Friction Sealing Materials
Release time:
2023-04-28
Barium sulfate is obtained from the mineral barite rich in barium sulfate, which also contains clay minerals, organic matter, and other substances. Pure crystals are colorless and transparent, often appearing gray white due to impurities. Stable chemical properties, insoluble in water and hydrochloric acid, non magnetic and toxic. The deep processing products of barite expand their application range, utilizing the characteristics of moderate hardness and high temperature resistance of barite
Precipitated barium sulfate has been widely used in friction sealing materials and has become an indispensable inorganic filler in friction materials. The use of precipitated barium sulfate can stabilize the friction coefficient, reduce wear rate, and ensure smooth and clean friction surfaces.
Precipitation of barium sulfate involves calcining barite and coal powder together in a reduction furnace, followed by impurity removal, water leaching, and pulping of the calcined products. Pump the slurry into the reaction tank, add mirabilite, heat with steam, and stir to accelerate the formation.
