CLEANING TREATMENT METHOD FOR SURFACE OF ALUMINUM FOIL

A cleaning treatment method for the surface of an aluminum foil. The method comprises the following steps: S1, selecting a rolling oil before a cold rolling process, wherein the distillation range of the rolling oil is 200-230°C; S2, adsorbing the rolling oil by using a cleaner, wherein the cleaner is provided on the output side of a roller; S3, performing cleaning and purging before annealing: first, scrubbing the surface of an aluminum foil by using hot water, and then drying the surface of the aluminum foil by using hot-blast air; and S4, placing the aluminum foil in an annealing furnace, removing the oil at a low temperature, then annealing same at a high temperature, and discharging the aluminum foil out of the furnace and cooling same to room temperature. In the cleaning treatment method for the surface of an aluminum foil, most of the rolling oil is removed by means of a physical method to ensure the content of the rolling oil for the aluminum foil before annealing; low-temperature annealing is first p
