摘　　要：以Y型分子筛为研究对象,针对其强吸水性的特点,考察了不同条件下对其结晶度和晶胞常数的影响。结果表明,在(110±5)℃的恒温条件下加热2 h,取出放在干燥器中冷却10 min后,并保持室内温度高、湿度低,并把样品压制成平整光滑的样片进行测量最准确,其硅铝比检测必须保证24 h以上吸水的稳化处理后再进行检测。Effects of testing conditions on the crystallinity and cell constants of Y molecular sieve possessing strong water absorption characteristics had been investigated.The results showed that measurement was accurate when samples were heated at(110±5)℃for 2 h,then cooled down for 10 min in dryer,and pressed into smooth flat at high room temoerature and low humidity.The determination of silicon to aluminum ratio was measured after more than 24 h stabilization of water absorption.
