Problems solved by technology

The three are mixed and deposited together, which increases the difficulty of removing radioactive pollutants
[0004] As we all know, using chemical methods to clean the surface of radioactively contaminated objects is a relatively common method. However, general chemical methods cannot achieve the ideal cleaning effect, even if some cleaning agents have certain effects on removing radioactive contamination from the surface of objects. effect, but the cleaning effect is generally unsatisfactory, and it is difficult to obtain practical applications. Therefore, we propose a cleaning agent for removing radioactive contamination on the surface of objects

Embodiment 1

[0022] Example 1: A cleaning agent for removing radioactive contamination on the surface of an object, consisting of the following volumes of components: 35 mL of EHS0106 cleaning agent, 1 mL of compounding agent, and 150 mL of solvent.

[0023] Put the steel plate containing radioactive dirt in the cleaning tank, inject the above-mentioned cleaning agent into the cleaning tank, soak for 0.5 hours at 15 degrees Celsius, and rinse the steel plate with rinse water.

[0024] Spray the cleaning agent evenly on the contaminated surface of the equipment at the production site. The cleaning temperature is 20 degrees Celsius, and the cleaning time is 8 minutes at a time. Rinse the equipment at the production site with flushing water.

Embodiment 2

[0025] Example 2: A cleaning agent for removing radioactive contamination on the surface of an object, which consists of the following volumes of components: 37 mL of EHS0106 cleaning agent, 1.3 mL of compounding agent, and 180 mL of solvent.

[0026] Put the steel plate containing radioactive dirt in the cleaning tank, inject the above-mentioned cleaning agent into the cleaning tank, soak for 1 hour at 20 degrees Celsius, and rinse the steel plate with rinse water.

[0027] Spray the cleaning agent evenly on the contaminated surface of the equipment at the production site. The cleaning temperature is 23 degrees Celsius, and the cleaning time is 9 minutes at a time. Rinse the equipment at the production site with flushing water.

Embodiment 3

[0028] Example 3: A cleaning agent for removing radioactive contamination on the surface of an object, consisting of the following volumes of components: 40 mL of EHS0106 cleaning agent, 1.5 mL of compounding agent, and 200 mL of solvent.

[0029] Put the steel plate containing radioactive dirt in the cleaning tank, inject the above-mentioned cleaning agent into the cleaning tank, soak for 1 hour at 26 degrees Celsius, and rinse the steel plate with rinse water.

[0030] Spray the cleaning agent evenly on the contaminated surface of the equipment at the production site. The cleaning temperature is 25 degrees Celsius, and the cleaning time is 10 minutes at a time. Rinse the equipment at the production site with flushing water.

Abstract

The invention discloses the technical field of cleaning agents and particularly relates to a cleaning agent used for eliminating a radioactive pollutant on the surface of an object, the cleaning agentcomprises the following components by volume: 35-45 parts of an EHS0106 cleaning agent, 1-2 parts of a mixture, and 150-300 parts of a solvent, the cleaning agent finishes cleaning the dirt by usingthe chemical dissolving action and the physical stripping action, the scale, the rust and the radioactive dirt on the surface of the object are separated from an iron body, the ions like Ca<2+>, Mg<2+>, Fe<2+>, UO22+ and U4+ rapidly form a complex and a chelate through the mixture, the dirt is promoted to dissolve rapidly, the dirt enters a cleaning fluid, the degree of the radioactive pollution of steel and iron materials and equipment on the production field are greatly reduced, the reuse ratios of the steel and iron materials and the equipment on the production field are increased, the level of radioactive pollution is reduced, the working environment is improved, and the cleaning agent is favorable for the body health of an operation staff.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to a cleaning agent for removing radioactive pollution on the surface of objects. Background technique [0002] With the development of the nuclear industry and the popularization of the application of nuclear technology, in the process of industrial production, scientific research and application, the surface of a large number of objects is polluted by substances containing radionuclides, especially the radionuclides attached to the dirt on the surface of objects. It is difficult to remove radionuclides, which makes a large number of materials, equipment, and buildings with high radioactivity on the surface, which affects the safety of the working environment, making it difficult to reuse contaminated materials, equipment, and buildings, and the utilization rate and utilization rate increase significantly. The reduction will cause significant economic losses, and it will al...
