Abstract

The invention provides a high-efficiency and environmental protection cleaning agent special for an aluminum pot. Production equipment, a heat-resistant and alkali-resistant stainless steel reactor and an acid and alkali-resistant mixer are prepared. The preparation process of the cleaning agent comprises the steps: first, starting production, and adding tap water of general water level to the reactor; second, adding 10-40% of caustic soda to the reactor in turn, turning on the mixer for mixing to dissolve completely, letting the mixture stand and cooled to the room temperature; third, turning on the mixer, and adding 0.5-3% of molybdate dissolving completely; forth, adding 0.5-5% of sodium gluconate, and mixing to dissolve completely; fifth, adding 0.5-5% of sodium polyacrylate with low molecular weight, and mixing to dissolve completely; sixth, adding 0.1-0.5% of sodium chloride, and mixing to dissolve completely; seventh, adding 0.1-0.5% of corrosion inhibitor, and mixing to dissolve completely; eighth, adding the surplus water, and mixing for half an hour till the solution concentration is uniform; ninth, filling after passing inspection. In the invention, the cleaning efficiency and the environmental protection performance are improved greatly.

Description

technical field [0001] The invention relates to the technical field of metal cleaning, in particular to a high-efficiency and environment-friendly cleaning agent specially used for aluminum cans. Background technique [0002] Aluminum cans stretched from aluminum ingots and refined through a series of processes are widely used in the packaging of medicine, food, and daily necessities. The most important process in the process of tank body processing is cleaning, and its cleaning effect determines the adhesion of the subsequent surface coating. However, the cleaning agent used in the cleaning of the existing tank body has certain non-environmental factors, and contains substances that are toxic to the human body or the environment, such as fluorine; it contains a certain amount of surfactant, which increases the difficulty of subsequent cleaning and the cost of wastewater treatment. rise. Such aluminum can cleaners are facing a situation of being phased out in today's incre...
