 白色结晶性粉末。为硫化锌和硫酸钡的混合物,含硫化锌越多,遮盖力越强,品质也越高。密度4.136~4.34 g/cm3,不溶于水。遇酸易分解产生硫化氢气体,遇硫化氢及碱溶液不起作用。受日光中的紫外线照射6~7h变成淡灰色,放在暗处仍恢复原色。在空气中易氧化,受潮后结块变质。
  用于油漆、油墨、橡胶等的着色。
  无机白色颜料,广泛用于聚烯烃、乙烯基树脂、ABS树脂、聚苯乙烯、聚碳酸酯、尼龙和聚甲醛等塑料及油漆、油墨的白色颜料。在聚氨酯和氨基树脂中效果较差,在氟塑料中则不太适用。还用于橡胶制品、造纸、漆布、油布、皮革、水彩颜料、纸张、搪瓷等的着色。在电珠生产中用作粘接剂。

White crystalline powder. It is a mixture of zinc sulfide and barium sulfate. The more zinc sulfide, the stronger the covering power and the higher the quality. 34 g / cm3, insoluble in water. It is easy to decompose with acid and produce hydrogen sulfide gas, but it doesn't work with hydrogen sulfide and alkali solution. It turns light gray after 6-7 hours of exposure to ultraviolet light in the sun, and it still returns to its original color in the dark. It is easy to oxidize in the air and agglomerate after being affected by moisture.

Used for coloring paint, ink, rubber, etc.

Inorganic white pigment, widely used in polyolefin, vinyl resin, ABS resin, polystyrene, polycarbonate, nylon, polyoxymethylene and other plastic and paint, ink white pigment. The effect is poor in polyurethane and amino resin, but not suitable in fluoroplastics. It is also used for coloring rubber products, paper making, lacquer cloth, oilcloth, leather, watercolor pigment, paper, enamel, etc. It is used as adhesive in the production of electric bead.
