摘要
由适宜的高岭土为原料合成出了性能优良的洗涤剂用４Ａ 沸石。钙交换容量以（ＣａＣＯ３ 计）达３１０～３２０ ｍ ｇ／ｇ 绝干沸石，相对白度９０％ ～９５％ ，粒径≤４ μｍ 。
A fine 4A zeolite used as detergent additives is synthesized from suitable kaoline.The reaction conditions to produce 4A zeolite and its properties,such as ion exchange capacity crystallinity and whiteness value,are investigated.The results show that the calcium exchange capacity of the synthesized 4A sample is 310～320mg CaCO 3/g.The diameters of particles are <4 μm and the relative whiteness is 90%～95%.
