锌盐类钛白初品浆料黏度研究
|
摘要
针对锌盐类钛白初品浆料浓度高时黏度大的问题,系统研究了盐处理剂加量、初品S含量、表面活性剂、浆料温度、pH和温度等因素对钛白初品浆料黏度的影响。试验结果表明:随着钾盐的增加,浆料黏度先增加后减少,随着锌盐加量的增加,浆料黏度逐渐减少,随着磷酸盐加量的增加,浆料黏度增加;初品中S含量越低,浆料黏度越低;高分子表面活性剂相对常用小分子表面活性剂的初品浆料黏度低;雷蒙磨研磨方式相对辊压磨研磨方式的初品浆料黏度略有降低,表面活性剂的加量越多则浆料黏度越低;浆料浓度高,则浆料黏度大,浆料温度高,则浆料黏度越低;随着pH的增加,浆料黏度先减少后增加。该研究为降低锌盐类钛白初品浆料黏度提供了技术指导。
According to the problem of high viscosity with high concentration of zinc salt initial titanium dioxide slurry,factors such as the amount of salt treatment agent,the S content of the initial titanium dioxide,surfactant,slurry temperature and pH were systematically studied.The results show that with the increase of potassium salt amount,the viscosity of the slurry increases first and then decreases.As the amount of zinc salt increases,the viscosity of the slurry gradually decreases.With the increase of phosphate amount,the viscosity of the slurry increases.The lower the S content in the initial titanium dioxide,the lower the slurry viscosity.The initial titanium dioxide slurry with polymer surfactants has a lower viscosity than the slurry with small-molecule surfactants.The slurry by Raymond mill grinding has a slightly lower viscosity than that by the roller-grinding.The more the amount of surfactants,the lower the slurry viscosity.Higher slurry concentration leads to a higher viscosity of the slurry,while a higher slurry temperature results in a lower viscosity of the slurry.With pH increases,the viscosity of the slurry decreases first and then increases.This study provides technical guidance for reducing the viscosity of the slurry of zinc salt initial titanium dioxide.
