Abstract

The invention relates to the technical field of nuclear power decontamination, in particular to a textile surface adhesive staining nuclide detergent and a preparation method thereof. The textile surface adhesive staining nuclide detergent is prepared from, by weight, 12-18% of a composite surfactant, 15-20% of a complexing agent, 8-14% of an enzyme preparation, 5-8% of an enzyme stabilizer, a pHregulator and the balance water. The textile surface adhesive staining nuclide detergent can meet the requirement for decontamination of nuclear power textiles, especially has an excellent decontamination effect on radionuclide contamination, does contain harmful ingredients, and has environment friendliness, and after decontamination is completed, the textile surface adhesive staining nuclide detergent is non-destructive to fabrics, easy to rinse, and free of residues.

Description

technical field [0001] The invention relates to the technical field of nuclear power decontamination, in particular to a textile surface adhesive contamination nuclide decontamination agent and a preparation method thereof. Background technique [0002] Decontamination of nuclear power textiles is traditionally commonly used detergent formula, liquid: 0.1% LAS plus 0.5% SHMP. Powder: 24% LAS, 47.8% sodium pyrophosphate or SHMP, 2% CMC, 24.4% sodium sulfate mixed, use concentration 0.25~5%. The decontamination efficiency is low, and the wastewater treatment is difficult. [0003] The decontamination of nuclear power textiles can be divided into three decontamination methods: dry decontamination, semi-dry decontamination, and wet decontamination according to the decontamination medium: 1) Dry decontamination: dry decontamination does not use polarity such as water Do not use solvents, nor use detergents that are soluble in polar solvents. The most common methods include beat...
