How the quality lithopone products can be produced

Lithopone is often used in water-borne coatings due to its excellent alkali resistance. It can be used as a bleaching agent and rubber reinforcing agent, and as papermaking filler and whitening agent.
Lithopone is a white pigment, a mixture of zinc sulfide and barium sulfate. By zinc sulfate and barium sulphide solution reaction and precipitation, filtering, drying and crushing, and then calcined to red, poured into water quench. It covers to titanium dioxide. Now some lithopone( Lithopone B311, Lithopone 30%,etc)with surface active agent for surface treatment. Lithopone is also a great uses in the cosmetics industry and pigment industry, such as canvas scraping the base materials need to be developed.
Industrial equipment and improve the level of. In the direction of large unit at the same time this industry, continue to increase investment in science and technology, technological transformation to device, application of new technology, new technology, new equipment, the overall level of equipment and technology industry has been the rapid increase. Large air swept mill instead of Raymond Mill ilmenite, vacuum crystallization tank instead of frozen crystallization tank for freezing, disc filter to replace the centrifuge for separation of ferrous, volume in 100m3 above large acid hydrolysis reaction kettle, large hydrolysis reaction kettle, large-scale rotary kiln, drying by spray and flash devices etc.. A large number of new equipment and the introduction of equipment put into use, greatly improving the technical level of domestic lithopone production equipment.
The lithopone product quality has been improved greatly. In recent years, our country in the industry enterprises has take actions through independent development and introduction, digestion, absorption and re innovation and other means.The products of whole industry,and its the structure, quality and use has been upgrading and development of larger, anatase lithopone products of special and special continuous development and mass production.
