Lithopone use and synthesis method
Chemical properties white powder, is a mixture of zinc sulfide and barium sulfate.Does not dissolve in water.
Use color for paint, ink, rubber, etc
Use inorganic white paint.Widely used for polyolefin, vinyl resin, ABS resin, polystyrene, polycarbonate, nylon and polyformaldehyde plastics and paint, ink, white pigment.Used in rubber products, cloth, leather, paper, enamel color.
Use inorganic white pigment, widely used in polyolefin, vinyl resin, ABS resin, polystyrene, polycarbonate, nylon and polyformaldehyde plastics and paint, ink, white pigment.In the polyurethane and amino resin effect is poorer, less applicable in fluorine plastic.Also used for rubber products, paper, cloth, cloth, leather, watercolor coloring, paper, enamel, etc.Used as a binder in buld production.
Methods the roasting leach process production.Reaction equations are as follows:
2 c + O2 - > 2 co2
BaSO4 + C - BaS + 4 co
BaSO4 co - BaS + 4 co2 + 4
BaS + ZnSO4 and ZnS, BaSO4 administered
Containing barium sulfate is greater than 95% of the natural barite and anthracite 3-1 (quality) mixed feeding, after smashing below about 2 cm diameter into the reduction furnace, furnace temperature control in 1000 ~ 1200 ºC, the period of 500 ~ 600 ºC, the reduction furnace turn at every turn to the 80 s, the reaction conversion rate is 80% ~ 90%, of barium sulfide into leaching device, control temperature above 65 ºC, barium sulfide content is 701%, then enter the clarifying tank, clarifies, adding zinc sulfate reaction, control of zinc sulfate content is greater than 28%, pH = 8 ~ 9, get 1.296 ~ 1.357 g/cm3 density of barium sulfate with a mixture of zinc sulfide.Reaction fluid through the plate and frame filter, get the filter cake shape lithopone, moisture content is not more than 45%, into the dry baking furnace roasting to change lithopone crystal type, and then at 80 ºC temperature with sulfuric acid pickling.The last are washed, fixing agent, filter, drying and grinding.
Production methods barite calcination method Barium sulphide solution (see barium sulfide).Adding sulfuric acid and zinc oxide reaction, potassium permanganate and refined zinc powder, zinc sulfate solution after compression.Add in preparation of barium sulphide solution mixed double decomposition reaction, a mixture of zinc sulfide and barium sulfate precipitation, and then, sediment filter, calcination, wet milling, drying, crushing, barium Bai Chengpin obtained zinc.its
ZnSO4 + BaS - ZnS + BaSO4 administered
