Abstract

The invention discloses a water base type metallic surface oil contamination cleaning agent for heat-pump water heater production, and belongs to the field of metallic surface cleaning agents. The cleaning agent comprises, by mass percent, 1%-2% of a glycine betaine surface active agent, 2%-5% of a nonionic surface active agent, 5%-10% of sodium carbonate, 2%-8% of sodium chloride, 0.5%-1% of a metal inhibitor, 1%-2% of a defoamer and the balance water. The water base type metallic surface oil contamination cleaning agent has the low surface tension, has the low interfacial tension with oil contamination, is low in critical micelle concentration, has the high solubilising power on oil contamination, can quickly dissolve oil contamination on the metal surface, and improves the cleaning efficiency; the cleaning agent can effectively prevent metal corrosion and is stable in using performance; the cleaning agent has the high cleaning capacity, can be used at normal temperature and is high in efficiency, free of pollution, free of foams, free of corrosion and the like; and the cleaning agent can be particularly used for cleaning complex and difficultly-cleaned metal pipes such as spiral winding pipes and heat-pump water heaters.

Description

technical field [0001] The invention relates to a water-based metal surface oil stain cleaning agent used in the production of heat pump water heaters, belonging to the field of metal surface cleaning agents. Background technique [0002] Before welding, electroplating and spraying processes, as well as during processing, pressing, assembly, storage and maintenance, cleaning metal parts is one of the indispensable process links, otherwise it will affect the quality of the product. [0003] At present, organic solvent cleaning agents are expensive and easy to pollute the environment, and solvent vapor is also harmful to human health. Therefore, special devices are needed to prevent solvent vapor from volatilizing and dispose of waste solvents; general water-soluble cleaning agents should be used at room temperature The effect is poor and the dosage is large, especially for complex and difficult-to-clean metal pipelines such as spirally wound pipes. The high-efficiency tank h...
