Cleaning agent for removing radioactive contaminants and preparation method thereof

Abstract

The invention discloses the technical field of a cleaning agent, and particularly relates to the field of a cleaning agent for removing radioactive contaminants and a preparation method thereof. The cleaning agent is prepared from the following ingredients in parts by weight: 30 to 45 parts of an EHS0107 cleaning agent, 1.5 to 3 parts of a compounding agent and 100 to 300 parts of a solvent; undera room temperature condition, a steel plate material is subjected to one-step soaking, wherein the cleaning is performed for 1 h and the cleaning efficiency can reach 80 percent or more; production field equipment is subjected to one-step spray coating cleaning, wherein the cleaning is performed for 10 minutes and the cleaning efficiency can reach 50 percent or more; the characteristics of high efficiency, high speed, small substrate corrosion, convenient use and the like are realized; the radioactive contamination degree of steel and iron materials and the production field equipment is greatly reduced; the reutilization rate of the steel and iron materials and the production field equipment is improved; the radioactive contamination level is reduced; the work environment is improved; thebody health of operators is facilitated.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to a cleaning agent for removing radioactive pollutants and a preparation method thereof. Background technique [0002] Nuclear technology refers to modern high-tech based on nuclear properties, nuclear reactions, and nuclear effects, and uses reactors, accelerators, radiation sources, and nuclear radiation detectors as tools. However, nuclear technology has also produced some problems in the process of industrial production, scientific research and application. A large number of materials, equipment and buildings are attached to the surface of radionuclides, and the dirt formed by radionuclides It is deposited with scale, oil and rust to form radioactive fouling. [0003] The main component of radioactive fouling is UO 2 , UO 3 、Na 2 u 2 o 7 and by UO 2 2+ Various uranium-containing salts formed by ions, such as: Na 4 UO 2 (SO 4 ) 3 , Na 4 UO 2 (CO 3 ) 3 Wai...

AI Technical Summary

Problems solved by technology

[0008] The removal of existing radioactive dirt is mainly water cleaning and acid-base solution cleaning, wherein water cleaning has a poor effect on natural radioactive pollution on the surface of objects, and generally can only clean solid particles and soft dirt attached to the surface of objects; acid-base solution cleaning, If the acid-base concentration is low, the cleaning effect is limited, and if the acid-base concentration is high, it may cause severe corrosion to the equipment. Therefore, we propose a cleaning agent for removing radioactive pollutants and its preparation method
