Titanium solution concentration and coating titanium concentrate reasons

Water in the titanium solution is a solvent that is volatile. Titanium sulfate in titanyl sulfate, titanium sulfate and ferrous sulfate is a solute, is not volatile. With the help of the heating effect, the solvent (water) in the titanium solution gradually vaporizes and volatilizes, and the solute concentration gradually increases. This process is called concentration.

Based on the titanium solution of low concentration, metatitanic particles made coarse, and then obtained titanium dioxide pigment performance is poor. In order to finely and uniformly obtain metatitanic acid particles obtained by hydrolysis of titanium liquid to obtain titanium dioxide with superior pigment performance, titanium dioxide solution having a lower concentration filtered through a crystallizing filter and a frame filter must be concentrated until concentration To Ti02 (200 ± 5) g / L (for hydrolysis) or 215-230g / L (for atmospheric hydrolysis) so far. In the case of producing non-pigment titanium dioxide, the titanium solution can be concentrated without concentration, and the ferrous sulfate crystals are removed and directly sent for atmospheric hydrolysis.
