Volume third, phase twenty-first, June 2004 Advances in titanium Ti Tanium industry Indusuy Progress Optimization of hydrolysis process and influence on finished product quality in titanium dioxide production by sulfuric acid process Li Juan (Panzhihua titanium dioxide plant, Sichuan, Panzhihua 617063) Abstract: from the perspective of transformation of Panzhihua titanium dioxide plant, and analyzes the influence of hydrolysis process on the quality of the finished product, and find out the main factors in the hydrolysis operation will sound product quality, combined with the optimization of the specific analysis of hydrolysis process production of Panzhihua titanium dioxide after the draw the conclusion: in the plus seed pressurized hydrolysis method, and the seed micro pressure hydrolysis method and in situ seed atmospheric hydrolysis method to these 3 methods, the last method is more reasonable, the quality of the products is the best. Keywords: hydrolysis; crystallization; titanium dioxide; particle size; particle size distribution 1 Preface Hydrolysis process is one of the most important processes in the production of titanium dioxide by sulfuric acid process. The hydrolysis effect not only affects the economy of industrial production, but also has a great influence on the quality of the final product. The error caused by hydrolysis can not be salvaged in the latter process. The industry of TiO2 whiteness, gloss, achromatic optical properties have strict requirements, which requires TiO2 products with particle size and size distribution of the crystal type and particle shape. The hydrolysis is a key step in
