  Detailed Description: Cas No. :1345-05-7 White crystalline powder. A mixture of barium sulfate and zinc sulfide, zinc sulfide containing more hiding the stronger, the quality is also higher. Density of 4.136 ~ 4.34 g / cm3, insoluble in water. Yi met acid decomposition of hydrogen sulfide gas, hydrogen sulfide and alkali solution does not work the case. By ultraviolet sunlight irradiation 6 ~ 7h become light gray, dark place still restore its original color. Easily oxidized in air, damp curdle.
Physical properties: white powder, is a mixture of barium sulfate and zinc sulfide. Its whiteness, strong hiding power than zinc oxide, the refractive index and opaque force of more than zinc oxide and lead oxide, titanium dioxide, but inferior


use
Lithopone good heat resistance, weather resistance can be improved, anti-algae, as well as reduce the cost of having excellent whiteness shielding force. Easily oxidized in air, damp caking. Whiteness, strong hiding power. Zinc sulfide containing more, hiding the more strong, and the quality is also higher. Barium sulfate and zinc sulfide precipitation from the reaction solution obtained, was filtered, dried and pulverized, and then calcined to red hot, poured into water quench derived. Hiding power inferior to titanium dioxide, intolerance concentrated sulfuric acid. Applications: Widely used as the polyolefin, vinyl resin, ABS resin, polystyrene, polycarbonate, nylon and POM plastics and coatings, paints, inks, plastics, rubber, linoleum, leather, paper, enamel, etc. .
