Product Description
Lithopone is a white powder, which is a mixture of zinc sulfide and barium sulfate. It is non-toxic. Its color is also called lithopone pink or zinc-barium white.
Lithopone is insoluble in water and can react with acidic substances to decompose and release hydrogen sulfide, but it will not react chemically with alkaline substances and hydrogen sulfide.
Lithopone has good heat resistance. Coating an object with a layer of lithopone can improve its weather resistance and prevent the growth of algae and moss. It is also a low-cost, non-transparent white powder. Its light-shielding rate is second only to titanium white.

Application
| 1 Ink is a kind of viscous fluid composed of color material, filler, additive and color developing agent. At present, printing newspapers, books, pictures and printing iron, printing metal, printing porcelain, printing rubber, printing plastic and printing radio semiconductor circuit boards are inseparable from ink. Because titanium dioxide has a large hiding power, high achromatous power, fine particles, dilute acid dilute alkali resistance, light resistance, heat resistance, not easy to yellowing, good hydrophobicity, small fluidity, insoluble in the color development agent and can be evenly dispersed in the color development agent, it is an indispensable color of advanced white ink and light ink. |

2 Paint is a viscous suspension composed of pigments, oils, paints (resins), solvents and drying agents. White pigment is the most widely used pigment, white paint and light paint are used in it, so in the paint, the amount of white pigment is much more than other pigments. The white pigments that can be used to make paint are often zinc white, zinc barium white and titanium dioxide. Due to the development of coating industry varieties, the emergence of synthetic resin coatings, its polymerization degree is large, such as adding zinc white, because of the zinc white alkaline, and the free fatty acid in the coating, and have a tendency to thicken; If zinc barium white is added, the weather resistance is poor. However, the use of titanium dioxide can improve the above shortcomings, because the particles of titanium dioxide are small and uniform, the photochemical stability is high, the covering rate is more than two times that of zinc white, zinc barium white, and the achromatic power is 5 to 6 times, so the amount of pigment in the entire paint can be greatly reduced. At the same time, the paint made is good in color, not easy to yellow, and has chemical stability such as heat resistance and acid resistance, sulfur resistance, alkali resistance, especially rutile titanium dioxide, its structure is stable, weather resistance is better than anatase type, ultraviolet radiation resistance, outdoor will not powder and other advantages. Therefore, it is suitable for all kinds of high-grade ships, Bridges, automobiles, buildings and other outdoor coatings with high weather resistance. Anatase titanium dioxide is generally only used for indoor paint. It can be seen that titanium dioxide has become an essential white pigment in the production of coatings. About 60% of the world's titanium dioxide is used in the production of various coatings. |
3 Plastic is a mixture of resin, plasticizer, filler and coloring agent, it has the characteristics of light weight, corrosion resistance, friction resistance, high mechanical properties, good electrical insulation, easy processing, beautiful and so on. It can be used as structural materials, insulating materials and corrosion resistant materials, and is widely used in various departments of the national economy, military industry and cutting-edge science and technology. In order to make plastics have beautiful colors, a certain amount of color is often added to plastics. The requirement for the color is that it is easy to color and disperse during processing, and does not react chemically with other components in the plastic. Due to the high whiteness of titanium dioxide, large achromatic power, good opacity and chemical stability, with titanium dioxide instead of Lide powder, the amount of white pigment can be reduced by 2 to 3 times, so the necessary coloring filler for the manufacture of white or colored plastics, is the best white pigment. When used in combination with other pigments, it can form beautiful bright colors, because toys and food utensils are non-toxic.

4 In the rubber industry, in order to improve the process performance of raw rubber in the processing process and the performance of vulcanized rubber, it is necessary to add vulcanizing agent, accelerator, active agent, antioxidant, reinforcing agent and colorant and other several kinds or a dozen kinds of additives to make physical and chemical changes in rubber. Titanium dioxide is a good coloring agent, because its physical and chemical properties are stable, small particles, does not contain impurities that damage the vulcanization process, will not damage the vulcanization process, because of its achromatogenic power and hiding power, the use of a small amount of titanium dioxide can achieve the best coloring effect, and the tensile capacity of the product, elongation and bending properties have no effect. At the same time, the sun resistance is strong, and it is not cracked and discolored under sunlight, so the general white and light-colored rubber products are indispensable titanium dioxide. |
| 5 Enamel is a metal body coated with a layer of porcelain glaze, after melting to obtain the product. The enamel has excellent opacity and a certain degree of acid resistance, alkali resistance, heat resistance and wear resistance, so that it can protect and beautify the metal. The glaze must have milky properties in order to make the glaze opaque. White enamels in particular must have stronger lactation properties. For this reason, emulsion must be added to the glaze. Titanium dioxide is the strongest emulsion in enamel. The products coated with titanium white enamel have smooth surface, strong acid resistance, good color and luster. Therefore, a large amount of titanium dioxide is used in the enamel industry. |

Lithopone is a kind of lithopone whose hiding power is better than that of zinc oxide and worse than that of titanium dioxide. It has good heat-resistance and is insoluble in water. It does not react with sulfured hydrogen and bases. It will decompose and produce sulfured hydrogen consequently when comes across acids. Its color will change after solarization for a long time but can return to its original color in dark place. It is a kind of important material in coatings, paints, rubbers, printing inks, paper, porcelain enamel, leathers and plastics.
