The physical and chemical properties: yuan jiang card - superfine modified precipitated barium sulfate (high whiteness universal) white powder, odourless, tasteless.Specific gravity of 4.50, is in the nature of common precipitated barium sulfate, in addition, narrow particle size distribution, good dispersibility.When used with colored paint can enhance the color and brightness.Good chemical stability, insoluble in water, alcohol and other solvents, but soluble in sulfuric acid.
Purpose: yuan jiang card - superfine modified precipitated barium sulfate (high whiteness universal) as a special functional filler, suitable for powder coating, paint, printing ink, plastic products, such as strong affinity ray resistance.Can absorb x-rays, gamma rays, and give material of high density and surface finish, and therefore is widely used in paint, printing ink, paint, plastic, rubber, ceramic, glass, electronics, cosmetics, medicine, food and other fields.
