摘　　要：文章通过对比不同基团类型、不同交联度树脂的含水量和脱水后堆积体积之间的关系,预测实际生产中不同树脂组合加热脱水后的减容比。文章研究了不同加热温度对树脂脱水行为以及基团降解幅度的影响规律。实验中使用的核级树脂脱水前后机械稳定性均能满足一般工业用对树脂机械强度的要求。脱水后树脂的抗渗透压能力基本不变,即使在极端工况下迅速吸水快速膨胀也不会产生裂纹球和破碎球,不影响工程应用中树脂输送的流动性。The article compares the water content of different kinds of resin （groups and degree of cross linking） with their accumulation volume after drying and predicts the volume reduction factor for combined resin. The article finds out the temperature impact on resin drying and active group degrading. The nuclear grade resin used in the test has well enough mechanical strength for industry use even after drying. Additionally, osmotical stability of the resin is nearly the same when it dries and absorbs the water again. In the duration, no broken or cracked resin beads happen to affect the resin transfer.
