The reason of radioactive soil formation includes following three points:
1, contain UO2, UO3Equal ore particles or dust etc. are attached to body surface.
2, contain Na2U2O7Solution is attached to body surface, after moisture evaporation, Na2U207It is present in body surface.
3, contain UO2 2+The solution of ion is attached to body surface, after moisture evaporation, such as containing uranium salt: Na4UO2(SO4)3,
Na4UO2(CO3)3Etc. there are body surfaces.
The main water cleaning of the removing of existing radioactive soil and acid-base solution cleaning, wherein water cleaning is natural to body surface
Radioactive pollution it is ineffective, generally can only cleaning object surface attachment solid particle and soft dirt；Acid-base solution
Cleaning, if acid base concentration is lower, cleaning effect is limited, if acid base concentration is higher, may generate heavy corrosion to equipment, be
This, we have proposed a kind of cleaning agents and preparation method thereof for removing radioactive pollutant.
Summary of the invention
The purpose of the present invention is to provide a kind of cleaning agents and preparation method thereof for removing radioactive pollutant, on solving
State the problem of proposing in background technique.
To achieve the above object, the invention provides the following technical scheme: it is a kind of for removing body surface radioactive pollution
Cleaning agent, be composed of the following parts by weight:
30~45 parts of EHS0107 cleaning agent
1.5~3 parts of compounding agent
100~300 parts of solvent.
Preferably, the EHS0107 cleaning agent include citric acid, carboxylic acid, hydrochloric acid, D-9, corrosion inhibiter, tin tetrachloride and
Formaldehyde is red.
Preferably, the compounding agent is N.N- dimethyl-thiocarbamic acid sodium and tetrasodium ethylenediamine tetraacetate.
Preferably, the solvent is deionized water.
Preferably, the corrosion inhibiter is water-soluble imidazoline quaternary ammonium salt corrosion inhibiter.
Preferably, include the following steps:
1) mixes compounding agent with deionized water, is heated to compounding agent and is completely dissolved, spare；
2) solution that step 1) is obtained quantify by above-mentioned parts by weight and be mixed by with EHS0107 cleaning agent, is stirred
It is uniformly mixed to it, obtains cleaning agent stoste, it is spare；
3) mixes the cleaning agent stoste that step 2) is obtained with the solvent of above-mentioned parts by weight, stirs evenly, obtains
The cleaning agent of body surface radioactive pollution must be used to remove.
Compared with prior art, the beneficial effects of the present invention are: it is a kind of for removing the clear of body surface radioactive pollution
Lotion, the present invention are compounded by EHS0106 cleaning agent with compounding agent, and new cleaning agent is had developed, at room temperature, right
Steel plate materials disposably impregnate, and clean 1 hour, and cleaning efficiency reachable 80% or more carries out production scene equipment disposable
Spraying cleaning, is cleaned 10 minutes, cleaning efficiency reachable 50% or more, is had and efficiently, quickly, to substrate is corroded small, user
Just the features such as, the cleaning agent complete the cleaning process of dirt using the dissolution of chemistry and the release effect of physics jointly, will
Scale, rust deposite and the radioactive soil and iron body of body surface are detached from, and effectively reduce cleaning agent to iron matrix by corrosion inhibiter
Corrosion, Ca is made by compounding agent2+、Mg2+、Fe2+、UO2 2+And U4+Plasma quickly forms complex compound and chelate, promotes dirt
Quick dissolution, dirt enters in cleaning solution, the radioactive pollution degree of steel material and production scene equipment is greatly lowered,
Steel material and production scene equipment reuse ratio are improved, radioactive contamination level is reduced, improves working environment, is conducive to operate
The health of personnel.
