Zhongcai Coloring High tech Zhongcai Brands B301, B311, Paint and Rubber Specialty Lithopone
Molecular formula: ZnS+BaSO4
Product Properties: Also known as lithopone, white powder, it is a mixture of zinc sulfide and barium sulfate. The density ranges from 4.136 to 4.39g/cm3. Insoluble in water. It is easy to decompose into hydrogen sulfide gas when encountering acid. Not effective with hydrogen sulfide and alkaline solutions. It is prone to oxidation in the air and deteriorates after being affected by moisture. Strong whiteness and covering power. By reacting sulfuric acid with zinc oxide, potassium permanganate and zinc powder are added for solution refinement, and after pressure filtration, a zinc sulfate solution is obtained. Add barium sulfide solution for double decomposition reaction to obtain a mixture of zinc sulfide and barium sulfate precipitation, which is obtained through pressure filtration, calcination, wet grinding, drying, and crushing.
Product characteristics: White powder, insoluble in water, does not react with hydrogen sulfide and alkaline solution, and dissolves in acid to produce hydrogen sulfide gas.
Product Usage: Widely used in the paint and coating industries, as well as in rubber, ink, enamel, plastic, paper, oilcloth, leather, PVC, and other fields.
Packaging: inner plastic outer woven, paper bags, net weight of each bag 50Kg or 25Kg
Product models: B301, B311, paint grade, rubber grade
Quality standard: Our company's standard
Transportation& Storage：
