- The China Titanium Dioxide Plant adheres to strict quality control measures to ensure that its products meet international standards. This commitment to quality has earned the plant a reputation for reliability and consistency in the global market. With a focus on research and development, the plant is constantly innovating to improve its processes and products, staying ahead of the competition.
- For example,;I have found that-if titanium acid cake is first added to the zinc sulphate solution, and then the lithopone-produced in the usual manner, that theresultaht product, upon mufiing, will form bluish compounds of titanium, which discolor somewhat the final product, and this discoloration is disadvantageous.
- Introduction
- The use of lithopone in rubber products extends beyond mere coloration. Its unique chemical composition allows it to act as an effective UV stabilizer, protecting rubber from the degradative effects of sunlight exposure. Furthermore, lithopone contributes to enhancing the strength and durability of rubber compounds. Its fine particle size and uniform dispersion within the rubber matrix lead to improved stress distribution, thereby reducing the likelihood of cracks and fractures under mechanical strain.

Titanium dioxide makes products, like toothpaste, white and bright. It's also used in makeup, sunscreen, plastic, and paint. (Photo Credit: iStock/Getty Images)
Lithopone B301, Lithopone B311 powder is widely used in coatings, printing ink, rubber, plastic industry, etc.

Background

For the First Quarter of 2022
Recent policy changes in regard to titanium dioxide
Additionally, the committee noted that the available data did not provide convincing evidence of genotoxicity for titanium dioxide as a food additive, but recognized the limitations in current methodologies with respect to the testing of poorly soluble particulate materials. Although there were uncertainties in the genotoxicity data, the experts took into account the fact that the additive was not carcinogenic in adequately conducted two-year studies in mice and rats at doses of up to 7,500 mg/kg BW per day for mice, and 2,500 mg/kg BW per day for rats, the highest doses tested. There was also no evidence of reproductive or developmental toxicity in studies in rats at doses up to 1,000 mg/kg BW per day, the highest doses tested.
However, it can cause photosensitivity, which is why it’s often combined with silica or alumina to prevent cell damage.
As a result, tariffs for titanium products are remaining similar to the ones in 2016, which will not cause bigger price fluctuations and keep a stable market.
The produced barium sulfide enters the leacher, and the temperature is controlled above 65°C to obtain a barium sulfide content of 70%, and then enters the clarification barrel, add zinc sulfate for reaction after clarification, control the zinc sulfate content to be greater than 28%, pH=8~9, and obtain a mixture of barium sulfate and zinc sulfide with a density of 1.296~1.357 g/cm3.
