低品位铝矾石制取洗衣粉用4A沸石

4A zeolite for defergent made from low-graded bauxite

本文讨论了用低品位铝矾石经烧结法制取NaAlO2溶液，替代氢氧化铝与水玻璃水热合成洗衣粉助剂4A沸石的工艺条件。

4A jeolite for detergent was synthesised in NaAIO, solution which was made bysintering from the substitution of low--graded pan-cite for aluminium hydroxide and waterglass. The effect of technology of sintering process on solubility of the sintered ban-cite is aLso discussed.
