水泥固化是固化废离子交换树脂的一种常规技术。作为提高水泥包装中树脂含量的第一步，对离子交换树脂的溶胀性能进行了理论和实验研究，首次根据Gregor的溶胀模型推导了树脂的溶胀压力公式。结果表明，压力与离子交换量、官能团类型、交联度、含水率等因素有关。随后，用一种新开发的方法对40多种不同交换容量、不同含水率等性质的阳离子交换树脂(DIAION SK系列)的溶胀压力进行了实验评价。根据离子交换树脂的性质，压力在0-60兆帕的范围内变化。这些结果与Gregor模型的计算值非常吻合，表明不需要借助实验就可以估算出溶胀压力。
Cement solidification is a conventional technique to solidify spent ion exchange resin. Swelling property of the ion exchange resin was investigated theoretically and experimentally, as the first step to improve resin content in a cement package.Swelling pressure of the resin was first formulated based on Gregor's swelling model. It was shown that the pressure depended on such factors as ion exchange capacity, type of functional group, crosslinkage and water content. Subsequently, swelling pressures for over forty properties of cation exchange resin (DIAION SK-series) with different exchang capacities, water contents and others were experimentally evaluated using an originally developed method. The pressure changed over a range of 0–60 MPa, depending on properties of the ion exchange resin. These results were in close agreement with values calculated by Gregor's model, indicating that the swelling pressure could be evaluated without resorting to experiments.
