lithopone

Description

Molecular formula : + BaSO4 CAS ZnS : ********7 nature : also known as the lithopone. White powder. Yes barium sulfate and zinc sulfide mixtures. 4.*9g/cm3 density of ~ 4.**6. Do not dissolve in water. Yi met acid decomposition of hydrogen sulfide gas. With alkaline solution of hydrogen sulfide and ineffective. Easy in the air oxidation, dried caking after metamorphism. White degrees, and hiding more. By sulfate and zinc oxide reaction, and by adding potassium permanganate solution for refined zinc powder, obtained by pressure filtration zinc sulfate solution. Then barium sulfide solution rehabilitation decomposition reaction, and zinc sulfide to be a mixture of barium sulfate precipitation, pressure filtration and calcination, wet grinding, drying, crushing obtained. For polyolefin, vinyl resin, ABS resin, polystyrene, polycarbonate, nylon and plastics such as POM, and the coatings, ink and white paint. Can also be used for rubber products, sealants, adhesives, Qibu, leather, paper, the colored enamel.
