 At present, Lide powder is mainly produced in China. Most of the domestic Lide powder production is still using traditional methods. The main raw materials are zinc oxide, sulfuric acid and barium sulfide (barite and coal are produced by high temperature reduction). Zinc 45% ~ 70%. The traditional method for producing the Liede powder process is to use zinc bakelite containing more than 45% zinc as a raw material to be leached with sulfuric acid to obtain a crude zinc sulfate solution, and then to remove iron by potassium permanganate, and then replace the heavy metal with zinc powder and filter to obtain zinc sulfate. The refined liquid is further subjected to metathesis reaction, pressure filtration, calcination, rinsing, drying, and pulverization with strontium sulfide to obtain a series of different types of lindose powder containing zinc sulfide of 30% or more. The whole process is carried out in an acidic (ra<7) environment, which consumes a large amount of sulfuric acid. The sulfuric acid has strong corrosiveness and requires high production equipment. The final discharged slag is acidic slag, which brings new pollution to the environment. High requirements, high production costs, and poor quality of the products obtained.

One of the key advantages of TR 28 titanium dioxide is its ability to enhance the performance of products in which it is used. Its high refractive index allows it to scatter light effectively, resulting in brighter colors and improved opacity Its high refractive index allows it to scatter light effectively, resulting in brighter colors and improved opacity Its high refractive index allows it to scatter light effectively, resulting in brighter colors and improved opacity Its high refractive index allows it to scatter light effectively, resulting in brighter colors and improved opacitytr 28 titanium dioxide manufacturer. This makes it a valuable ingredient in products where color and appearance are important.

As China's production and consumption of talc and titanium dioxide continue to grow, the country has become an increasingly important player in the global market for these minerals. In addition to meeting domestic demand, China has also emerged as a major exporter of both talc and titanium dioxide, shipping large quantities of these minerals to countries around the world. This has helped to establish China as a key supplier of these essential minerals, further cementing its position as a global economic powerhouse.
