Titanium(IV) oxide production main methods and LvHuaFa sulfuric acid method. 1310-73-2 Sulfuric acid method is to use titanium concentrates or acid soluble titanium slag and sulfuric acid solution reactions reaction, get oxygen titanium sulfate solution, via hydrolysis get partial titanium acid precipitation; Turn again into the kiln firing TiO2 output. Sulfuric acid method with intermittent method mainly operation, flexible production device, to open parking and load adjusting. But the process complex, need to nearly 20 way process step, every process step must be strictly controlled to produce the best quality product of Titanium(IV) oxide, and satisfies the pigment optimal performance. Sulfuric acid method can not only production sharp 1310-73-2 titanium type products, and can produce rutile type products.

LvHuaFa is to use the containing titanium material, chlorinated high titanium slag, or artificial rutile, or natural rutile and reacts with chlorine four chlorinated titanium, purification by distillation, and then the gas phase oxidation; In speed cold, after a gas-solid separation get TiO2. This TiO2 for a certain amount of chlorine absorption, need to undertake heating or steam treatment will be removed away.

The process is simple, but in 1000 ℃ or higher chlorinated conditions, there are many chemical engineering problems such as chlorine, chlorine oxide, titanium high corrosion of four chloride to be solved, plus of the raw materials used by the special, compared with sulfuric acid method of high cost. LvHuaFa production for the continuous production, the production equipment operation flexibility is not big, open parking and production load is not easy to adjust, but its continuous process production, process simple, process 1314-13-2 control points less, product quality is easy to reach the optimal control. Plus did not turn kiln firing of the formation of the sintering process, its TiO2 particles to the original level depolymerization, so have so people used to think that the apparent in the LvHuaFa titanium dioxide more excellent product quality.
