 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.

Plus, titanium dioxide is chemically inert, meaning it won't react with other substances in the paint. This stability ensures that the paint retains its original color and properties over time, preventing discolouration and degradation. Using titanium dioxide as an ingredient, the paint can withstand harsh weather conditions and prevent flaking, peeling or chalking. This exceptional durability makes it ideal for interior and exterior walls, ensuring a long-lasting and beautiful finish.

In various industries such as paints, coatings, plastics, and cosmetics, the pH of titanium dioxide must be carefully controlled to achieve the desired performance. In the paint and coatings industry, for instance, titanium dioxide is used as a pigment to provide opacity and brightness to the final product

Furthermore, the use of titanium dioxide in water purification systems is another example of how this mineral contributes to environmental sustainability. With its strong oxidative properties, titanium dioxide can effectively remove pollutants and contaminants from water, making it safe for consumption. By incorporating titanium dioxide into water treatment processes, China is able to provide clean and safe drinking water to its citizens.

  • In the plastic industry, TiO2 is also used as a UV stabilizer to protect plastic products from the harmful effects of sunlight. This makes TiO2 an essential ingredient in outdoor plastic products such as vinyl siding, PVC pipes, and plastic films

  • In a study published in the journal Environmental Toxicology and Pharmacology in 2020, researchers examined the effects of food additives titanium dioxide and silica on the intestinal tract by grouping and feeding mice three different food-grade particles — micro-TiO2, nano-TiO2, and nano-SiO2.  With all three groups, researchers observed changes in the gut microbiota, particularly mucus-associated bacteria. Furthermore, all three groups experienced inflammatory damage to the intestine, but the nano-TiO2 displayed the most pronounced changes. The researchers wrote: “Our results suggest that the toxic effects on the intestine were due to reduced intestinal mucus barrier function and an increase in metabolite lipopolysaccharides which activated the expression of inflammatory factors downstream. In mice exposed to nano-TiO2, the intestinal PKC/TLR4/NF-κB signaling pathway was activated. These findings will raise awareness of toxicities associated with the use of food-grade TiO2 and SiO2.”
