摘要
以硫酸法钛白生产过程的中间产品TiOSO4液为原料 ,经过萃取、酸洗、反萃、胶溶得到透明的TiO2水溶胶 ,再加入阴离子有机表面改性剂使溶胶中Ti粒子转化成憎水性凝聚体 ,然后将Ti粒子转入到有机溶剂中 ,得到钛的有机溶胶。
The TiOS 4 solution which is the intermediate product in titanium white making with sulfuric acid process is used as raw material.The transparent water collosol is prepared by extraction,pickling,back washing and peptizing.Titanium oxide particle is changed into hydrophobic agglomerate by adding anion organic surface modifying agent into the collosal.Then,the titanic organic solution can be gotten by putting the particle into organic solvent.The mechanism of peptisation and organic modification is generally described in this paper.
