Radioactive waste resin curing agent and curing method thereof
The invention provides a radioactive waste resin curing agent and a curing method thereof, and belongs to the technical field of radioactive waste resin curing. The radioactive waste resin curing agent comprises a binding material, radioactive waste resin, polypropylene fibers and water, the mass ratio of the binding material to the radioactive waste resin to the water is (1-6): 1: (0.7-1.8), the mass of the polypropylene fibers accounts for 0.1-0.3% of the total mass of the binding material and the radioactive waste resin, and the binding material comprises mineral powder and solid instant sodium silicate. The inclusion capacity of the radioactive waste resin in the radioactive waste resin solidified body prepared by the invention reaches 60%, the compressive strength can reach 38.7 MPa, and the radioactive waste resin solidified body cannot absorb water to expand and crack in the curing process. The radioactive level of the radioactive waste resin cured body prepared by the invention is reduced by 12.4 times compared with the radioactive level of uncured radioactive waste resin.
本发明提供了一种放射性废树脂固化剂及其固化方法，属于放射性废树脂固化技术领域。本发明的放射性废树脂固化剂包含胶凝材料、放射性废树脂、聚丙烯纤维和水，其中胶凝材料、放射性废树脂和水的质量比为1～6：1：0.7～1.8，聚丙烯纤维的质量占胶凝材料和放射性废树脂总质量的0.1～0.3％，胶凝材料包含矿粉和固体速溶硅酸钠。本发明制得的放射性废树脂固化体中放射性废树脂的包容量达到60％，抗压强度可达38.7MPa，在养护过程中不会吸水膨胀破裂。本发明制得的放射性废树脂固化体的放射水平相较于未固化的放射性废树脂的放射性水平降低了12.4倍。
