Radioactive Treatment Resin


Radioactive Treatment Resin

Radioactive treatment ion exchange resins refer to ion exchange resins that can be used in the primary and secondary radioactive water treatment and radioactive waste treatment of power plants. Among them, the radioactive treatment mixed bed resin is mixed with radioactive treatment cation resins and radioactive treatment anion resins in different proportions. It is mainly used for the desalination, purification and refinement of the primary and secondary circuit coolants and waste liquid of power plants, as well as the removal of radioactive elements. In addition to purification and recycling of radioactive waste. The radioactive treatment resins used in the primary circuit water treatment system of radioactive power plants has high requirements for regeneration transformation rate, resistance to radiation decomposition, mechanical strength and high temperature stability.


Ionizing radiation can change the physical, chemical and biological properties of the irradiated material. The main industrial applications of radiation include the sterilization of health products including medicines, and the irradiation of food and agricultural products. The gamma radiation source needs to be stored in a storage tank, and the storage tank needs to provide deionized water. The use of anion and cation radioactive treatment resins can obtain deionized water that meets the storage requirements of gamma radiation sources and maintain the purity of the water.

Radioactive treatment resins plays a vital role in the operation of various factories because it is widely used to treat pollutants or ionic impurities (radioactive substances) from different systems of factories (including radioactive reactors). Radioactive treatment resins are the most important material in the first-loop coolant purification system of radioactive power plants. Its quality and performance directly affect the quality of the effluent from the condensate treatment device, which in turn affects the economic safety of unit operation. For the same type of radioactive treatment cation exchange resins, the greater the degree of crosslinking, the better the oxidation resistance of the resins. With the same degree of cross-linking, the gel-type resins have better oxidation resistance than the macroporous resins.
