A large number of aluminum products will be coated with stretching oil in the process of stretching molding to prevent product from being strained and broken.In order to clean the heavy oil residue on the surface,it is necessary to use a cleaning agent containing a large number of surfactants.To solve the problems of difficult cleaning and high pollution emissions in traditional aluminum product cleaning,an oil-separated water-based cleaning agent was studied.The results show that the oil-separated water-based cleaning agent is a low foam type cleaning agent,and the cleaning effect is the best under the conditions of cleaning temperature of 50℃,cleaning time of 5 min and cleaning agent concentration of 5%,the oil removal rate can reach over 99%.The performance meets the requirements of water-based metal cleanser industry standard of JB/T 4323-2019.The actual application results show that the cleaning amount of oil-separated water-based cleaning agent exceeds 32 times that of conventional water-based cleaning agent,and cleaning one million battery shells can reduce the discharge of concentrated water by 116.25 t and hazardous waste volume by 16.25 t,which has profound significance for enterprise efficiency improvement and energy conservation and emission reduction.
