摘要
通过调节高岭土矿浆的pH值到8.5—9,使用6种分散剂单独或复配应用的方法,改变高岭土浆料的分散特性,提高粘浓度。结果表明:单独使用时,分散效果聚丙烯酸钠>萘磺酸钠>胶易素1>六偏磷酸钠>胶易素2>单宁酸;复配使用时,六偏磷酸钠与萘磺酸钠以质量比1∶1配合为最佳,可以将高岭土浆料粘浓度从69.7%提高至71.3%。
The methods of improving the pH value to 8.5-9 and applying single (six types) and compound dispersants change the viscosity properties and enhance the viscosity content of kaolin slurry. The results showed that as a singe dispersant used, the effects are sodium polyacrylate 〉 sodium naphthalenesulfonate 〉 Jiaoyisul 〉 hexametaphosphate 〉 Jiaoyisu2 〉 tannin; as compound dispersants used with the mass ratio 1 : 1 of hexametaphosphate and sodium naphthalenesulfonate, the viscosity content of kaolin slurry can be improved from 69.7% to 71.3%.
