Peeling off type pressed detergent

Abstract

The detergent is composed of main agent component and adjuvant component. The main agent includes components and dosages: film forming material 75-90 and plasticising agent 3-5; and the adjuvant component includes components and dosages: thickening agent 2-5, stuffing 2-10 and flash dry agent10. The invention possesses pressing and decontaminating dual functions. Contamination is radioactive aerosol in air and radioactive deposits in not fixity on ground. Consecutive membranes are formed after washing, wetting, diffusing, adsorbing and sticking etc. procedures on the aerosol and deposits. Using machine retrieves membranes so as to reach purpose for cleaning out membranes. The detergent forms continuous membranes with index of mechanical properties being met to requirement of mechanical retrieve. The detergent is suitable for cleaning out radioactive contamination on each complicated ground including surface of concrete, road surface of cement and bitumen, farmland etc. in field.

Description

[0001] Technical field [0002] The invention belongs to the technical field of engineering decontamination, and mainly relates to a peeling type pressed decontamination agent. Background technique [0003] Along with the development and application of nuclear energy, radioactive pollution has attracted increasing attention. In extraordinary circumstances such as nuclear power plant accidents, nuclear strikes or quasi-nuclear strikes, a large amount of radioactive substances will leak into the external environment, causing serious damage to the air, water, soil and other environments. Pollution seriously endangers the living environment of animals, plants and people, and the human body in the polluted area is exposed to radioactive substances exceeding the standard in a short period of time, which will lead to radiation damage or death. [0004] In the technical field of large-scale decontamination of nuclear pollution, the method of transferring the radioactive dust settled o...

AI Technical Summary

Problems solved by technology

[0007] (1) The requirements for the surface finish of the decontamination object are relatively strict;

[0008] (2) Special spraying equipment is required;

[0009] (3) It does not have the ability to suppress and absorb radioactive aerosols in the air;

[0010] (4) The cost of decontamination per unit area is too high, and the cost performance does not have the value of large-scale field application;

[0011] (5) The formed film body needs to be removed manually, the operation efficiency is low, the labor intensity is high, and the personnel are exposed to high doses;

[0012] Therefore, limited by the performance of materials, it is difficult to popularize existing achievements in nuclear accident emergency or other large-scale radioactive pollution removal processes.
