摘要: 以环氧树脂/固化剂双组分体系作为混凝土高完整性容器(HIC)的密封材料,对其固化体的性能进行了分析,并探究了其固化过程中的温度变化规律,确定了最大温升限值,并对该密封材料密封的混凝土HIC进行了跌落试验和剖切试验。结果表明,所选用的环氧树脂/固化剂双组分体系密封材料,对模拟的放射性废物具有良好的密封包容性能,与工程应用验证试验所使用的设备装置配合,可以满足混凝土HIC密封操作要求。

Abstract: In this paper, the engineering applicability of epoxy resin/solidification agent is studied. The temperature change law of the solidification process of sealing material is explored and the temperature rise limit value is determined. The concrete HIC sealing process with the epoxy material was verified by engineering scale equipment. The results show that the operational performance, temperature rise amplitude and impact resistance of the epoxy resin/solidification agent meet the application conditions of HIC sealing engineering.

Key words: epoxy resin, High Integrity Container (HIC), sealing material
