稳定性 | 是复合的胶态物质,它的有代表性的化学组成为:二氧化硅61.1%,氧化镁13.7%,氧化铝9.3%,二氧化钛0.1%,氧化铁0.9%,氧化钙2.7%,氧化钠2.9%,氧化钾0.3%,二氧化碳1.8%,结合水7.2%。白色小型片状或粉状,无味无臭,质软而滑爽,含水量小于8%。不溶于水或醇,在水中可膨胀成较原来体积大许多倍的胶态分散体。黏度(5%水分散体)0.25Pa·s±25%。pH值(4%水分散体)约为9。使1g硅酸镁铝的pH减至4,需要0.1mol·L-1HCl6~8mL。硅酸镁铝的膨胀性是可逆的,它能在水中分散,也可以干燥后重新水合,不论次数。它一般用于低固体含量的水分散体中,在广泛的pH范围内稳定。当硅酸镁铝分散于水中时,形成胶态溶胶和凝胶。该水分散体的黏度随含量不同而变化。当含量为1%~2%时其分散体为胶态悬浮体,大于8%时为非透明体,黏度迅速增加,4%~5%时为厚的白色溶胶,当达10%时则形成坚硬的溶胶。硅酸镁铝通常的用量为0.5%~2.5%。硅酸镁铝水分散体具有明显的变性。在配制分散体时,需要适当地加热和适当地延长搅拌时间,才能达到一定的稠度。硅酸镁铝和少量的纤维素胶混合时,能明显地增高黏度,并且长期稳定。硅酸镁铝水分散体遇某些电解质变稠,甚至部分凝聚。 |
