Embodiment 1

[0019] A radioactive foam detergent prepared from the following raw materials: sodium bicarbonate 0.5%, ethanolamine 8%, sodium N-lauroyl glutamate 1%, narrowly distributed fatty alcohol polyoxyethylene ether sodium sulfate 7%, alkanes 8% glucoside, 0.5-3% sodium glucoheptonate, 7% propylene glycol, and the balance is water.

[0020] The preparation method is as follows: firstly weigh the amount of water in the formula, add sodium bicarbonate, dissolve, and stir evenly; then add ethanolamine, sodium glucoheptonate, propylene glycol, stir to dissolve completely, and finally add N-lauroyl glutamic acid 1% of sodium, 7% of narrowly distributed fatty alcohol polyoxyethylene ether sodium sulfate, and 8% of alkyl glycosides are used to obtain a finished radioactive foam detergent.

Embodiment 2

[0022] A radioactive foam detergent prepared from the following raw materials: 1% sodium bicarbonate, 4% triethanolamine, 2% sodium N-lauroyl glutamate, 5% sodium sulfate of narrowly distributed fatty alcohol polyoxyethylene ether, Alkyl glucoside 8%, sodium glucoheptonate 0.5%, propylene glycol methyl ether 5%, and the balance is water.

[0023] Its preparation method is with embodiment 1.

Embodiment 3

[0025] A radioactive foam detergent prepared from the following raw materials: 3% sodium bicarbonate, 2% ethanolamine, 2% sodium epi-N-lauroyl glutamate, 5% narrowly distributed fatty alcohol polyoxyethylene ether sodium sulfate, Alkyl glucoside 8%, sodium glucoheptonate 1%, propylene glycol tert-butyl ether 8%, and the balance is water.

[0026] Its preparation method is with embodiment 1.

Abstract

The invention discloses a radioactive foam detergent which is prepared from the following raw materials: 0.5-5% of sodium bicarbonate, 0.5-8% of ethanolamine or triethanolamine, 0.5-3% of a surfactant, 0.5-3% of a complexing agent, 5-10% of a cosolvent and the balance of water. The decontaminating agent is weak in alkalinity and small in corrosion to the surfaces of various materials, and due to the existence of sodium glucoheptonate, the decontaminating agent has high complexing and decontaminating capacity on various metal ions. The contained sodium glucoheptonate has better environmental compatibility; and compared with other complexing agents, EDTA complexing products are difficult to degrade, phosphate may cause phosphorus enrichment, sodium glucoheptonate is made of glucose and is easy to degrade, and sodium glucoheptonate has high complexing capacity for calcium and magnesium ions, so that the detergent can be applied to hard water quality, and deionized water is not needed forpreparation.

Description

technical field [0001] The invention relates to a radioactive foam detergent and a preparation method thereof. Background technique [0002] Since the 1960s, the United States began to study the application of chemical foam to radioactive decontamination. The principle of foam decontamination agent is to decontaminate the surface of contaminated parts with foam carrying decontamination agent. The biggest advantage of this method is that the amount of secondary waste generated is much smaller than that of ordinary decontamination solution soaking method, especially suitable for large-volume empty areas. cavities or complex shaped objects. Foam decontamination technology has been developed for nearly 60 years, and its application in engineering has become increasingly mature. The most representative one today is the two-step foam decontamination device jointly developed by Britain and France. The components of foam decontaminants that have been applied in engineering have th...
