Titanium dioxide, as an important inorganic chemical pigment, has always attracted much attention in terms of its production processes and market applications. Recently, there have been some new developments in the production processes. The sulfuric acid process, as a traditional titanium dioxide production process, has a relatively mature production flow and technology after long – term development and improvement, and it is still one of the main production processes in China. Its main raw material is titanium ore. There are a large number of mineral resources in regions such as Sichuan, Panxi, and Chengde in China, providing a sufficient and stable raw material supply for the production of titanium dioxide by the sulfuric acid process. However, the sulfuric acid process also has some drawbacks, such as a long production flow, high energy consumption, and the generation of a large amount of waste acid and waste residue, which are extremely difficult to handle. Currently, technical engineers are constantly exploring to overcome these problems and promote the continuous progress of the sulfuric acid production process.
At the same time, certain breakthroughs have also been made in the chloride – process titanium dioxide production process. The chloride process has the advantages of high production efficiency, good product quality, and low environmental pollution, and it is gradually favored by enterprises. Some enterprises have increased their investment in the research and development and application of chloride – process technology. Some enterprises have achieved large – scale production, and the market share of chloride – process titanium dioxide is expected to further expand in the future.
In terms of market applications, titanium dioxide is widely used in multiple industries such as coatings, plastics, paper – making, inks, and cosmetics. In the coatings industry, titanium dioxide can improve the weather resistance and hiding power of the coating, improve the physical and chemical properties of the coating, and make the coating film more durable. In the plastics industry, it can improve the light resistance, UV resistance, and heat resistance of plastic products, and extend their service life. In the paper – making industry, titanium dioxide can provide good hiding power and smoothness, improving the quality of paper. In the ink industry, it can make printed products have more vivid colors and higher gloss. In the cosmetics industry, titanium dioxide can make cosmetics more delicate and smooth, and at the same time improve their hiding power and stability. With the continuous improvement of product performance requirements in various industries, higher requirements have also been put forward for the quality and performance of titanium dioxide, which also prompts titanium dioxide enterprises to continuously innovate and improve production processes to meet market demands.
