摘要
详述了用煤矸石合成 4 A沸石的新工艺 ,制备了优良的洗涤剂助剂 4 A沸石。钙离子交换能力达 2 95mg Ca CO3/ g,相对白度 90 ,平均粒度 1 .69μm。
In this paper,we discussed a new technology process of Synthesizing 4A Zeolite from gangue. Ca exchange ability of 4A Zeolite made from gangue is 295mg CaCO 3/g,its whiteness is 90,and the powder's average size of the powder is 1.69μm.
