plastic and dyeing used titanium dioxide r218 factories

In addition, with the increasing demand for zinc compounds and lithopone, the continuous exploitation of zinc resources in China, the increasingly poor, fine and complex mineral resources, the comprehensive utilization and environmental protection requirements continue to improve, people have begun to study the recovery of low-zinc raw materials. Use technology. The so-called low-zinc raw materials are mainly low-grade zinc oxide ore, but in addition to low-grade oxidation In addition to zinc in zinc ore, zinc is also present in the acid leaching residue.

Lithopone was developed in the 1870s as a substitute for lead carbonate (lead white), to overcome its drawbacks of toxicity and poor weathering resistance. Within a few years, titanium dioxide displaced lithopone to become the white pigment (PW6) par excellence in the industry and the world’s best-selling inorganic pigment. However, titanium is a product whose price is subject to large price variations due to product availability. These price increases affect the competitiveness of finished products, and so the search for an alternative to titanium dioxide has generated a variety of possibilities to optimise its use.

In addition to sustainability, chemical pigment manufacturers also need to focus on creating pigments that offer high performance and durability. Pigments need to withstand various environmental factors, such as sunlight, heat, and moisture, without losing their color or fading over time. This requires extensive testing and quality control measures to ensure that the pigments meet the industry standards and requirements for different applications.
