【摘要】 以高岭土为原料,经预处理、锻烧、配料、晶化合成出合格的洗涤剂用4A沸石产品,钙交换容量为287.3mg CaCO₃/g沸石,平均粒径2.96μm,白度86.5°。通过添加高活性导向剂显著缩短晶化时间,最佳晶化时间从3h缩短到1h,钙交换容量提高到295.0mgCaCO₃/g沸石。更多还原

【Abstract】 The 4A zeolite for detergent was synthesized by a series of processes including pretreatment, burning, compounding and crystallization form kaolin. The product has high calcium exchange ability of 287. 3mg CaCO3/g zeolite, average particle size of 2. 96μm and whiteness of 86.5° Through adding high active directing agent, the crystallization period was reduced from 3h to 1h and the calcium exchange ability was increased to 295.0 mg CaCO3/g zeolite.更多还原
