Description of use
YLFTlithopone, also known as lithopone, is a kind of whitecolor powder,YesMixture of zinc sulfide and barium sulfate.relative density4.136-4.39. Insoluble in water,When exposed to acid, it is easy to decompose to produce hydrogen sulfide gas.With hydrogen sulfide and alkaliReaction. It has good heat resistance, can improve weather resistance, algae resistance, reduce cost and whiteness with excellent hiding power.It is easy to oxidize in the air and agglomerate after being affected with moisture. Whiteness, strong hiding power. The more zinc sulfide, the stronger the hiding power and the higher the quality.The precipitate obtained by the reaction of zinc sulfate and barium sulfide solution is filtered, dried and crushed.CalcinedBurn to red heat, pour into water and quench. The hiding power is inferior to titanium white,intoleranceconcentrated sulfuric acidAcid.
Scope of application:Widely used as polyolefin, vinyl resin,ABS resin, polystyrene, polycarbonate, nylon and polyoxymethylene and other plastics andPaint, paint, ink,Plastic,Rubber products, lacquered cloth, leather, paper, enamel, etc.
