ElNECS No. 236-675-5 Similar to the dupont 902 Chloride Process Titanium Dioxide
Specifications:
1, Liangjiang Brand rutile titanium dioxide R920 is manufactured through chlorination process, using high-quality titanium ore as the main raw material, after chlorination, refining, oxidation and surface treatment.
2, Liangjiang Brand rutile titanium dioxide R920 is coated with ZrO2, Al2O3 and special organic treatment. The features are of neutral hue, high gloss, high weatherability, high covering power, excellent dispersion, etc. With excellent resistance to pulverization, our R920 can substitute other high-grade titanium dioxide products like Dupont R902.

Description:
1. Sulfuric acid process titanium dioxide
Advantages: use cheap titanium ore (or titanium slag) and sulfuric acid as the main raw materials, of long-history technology, proven technique and low production cost.
Disadvantages: process, long process, serious pollution to the environment, low product quality stability
2. Chlorination process
Advantages: using the less impurities artificial rutile of 90% tio2 purity as the raw material, short process flow, production capacity easy to expand and continue, high quality.
Disadvantages: because of the monopoly of the foreign companies, it’s hard to bring in the foreign technology and equipment in China. Besides, due to the raw material of high content titanium dioxide ore, the production cost is relatively high and the process is hard.
Due to the different raw materials and production process, the product performance is different and has different requirements to the weather resistance, hiding power, aesthetics and dispersion titanium dioxide. So the clients should choose titanium dioxide of different quality based on their needs.
