| 摘 要： | 为了将中、低放射性废树脂固化成稳定的固化体,采用环氧树脂为基材,通过添加合适的固化剂、稀释剂、阻燃剂等进行固化配方试验研究。结果表明,配方为E-44环氧树脂∶651固化剂∶添加剂=1∶0.53∶0.05(38∶20∶2)、质量包容率50%时,其固化体性能最优,并满足国标GB 14569.2的要求,研究结果表明采用环氧树脂体系固化放射性废树脂是可行的。

| Abstract: | In order to solidify medium and low radioactive waste resins into a stable solid form to meet the disposal conditions, the solidification formula was studied by using epoxy resin as substrates with addition of appropriate curing agent, diluents and flame retardant. Experimental results show that when the formula is E-44 epoxy resin∶651 curing agent∶diluents=1∶0.53∶0.05 (38∶20∶2), and the quality tolerance is 50%, then the solidified body has the best performance, which meets the requirements of GB 14569.2. The results prove that solidifying radioactive waste resin with epoxy resin is feasible. |
