PROCESS FOR PREPARATION OF PIGMENT TITANIUM DIOXIDE OF RUTILE MODIFICATION |
| 摘要 |
A process for preparation of pigment titanium dioxide of rutile modification comprises the stages of salt treatment, burning, fragmentation, surface treatment of titanium dioxide by salts, filtering and drying of the finished product. The surface treatment is carried out by the salts of titanium and aluminum (in equivalent of АlO) in the ratio 1:3 – 1.5:4. Titanyl sulfate with the molar ratio of ТіО: HSО= 1:2.5 is used as the salts of titanium. |
