Method and device for removing aluminum of base membrane

Abstract

The invention discloses a method for removing aluminum of a base membrane. The method is characterized by including the following steps: (1) feeding the base membrane with the surface containing an aluminum coated layer into a cleaning solution to carry out aluminum removing, (2) feeding the base membrane into clear water to carry out cleaning, and (3) drying the base membrane. A device for removing the aluminum of the base membrane is adopted in the method for removing the aluminum of the base membrane and comprises a cleaning groove, a base membrane reeling-unreeling mechanism and a drying oven. The cleaning groove is divided by a partition plate into a cleaning solution groove and a clear water groove, the drying oven is located behind the cleaning groove, and the base membrane reeling-unreeling mechanism sequentially passes through the cleaning groove and the drying oven. The device for removing the aluminum of the base membrane is characterized by further comprising a cleaning solution circulation filtering mechanism. According to the method and device, the cleaning solution circulation filtering mechanism is additionally arranged in an aqueous alkali circulation system, the cleaning solution located at the top is overflowed from the cleaning solution groove to the cleaning solution circulation filtering mechanism, suspended matter in the cleaning solution is filtered out, the filtered cleaning solution returns to the interior of the cleaning solution groove again through circulation to be continuously used, and the use efficiency of the cleaning solution is improved.

Description

technical field

[0001] The invention relates to a method and equipment for dealumination of a basement membrane, and more specifically relates to a method and equipment for dealumination of a basement membrane in which the cleaning solution can be recycled and the concentration of the cleaning solution can be automatically adjusted in temperature. Background technique

[0002] Although the existing base film dealumination equipment can clean the aluminized layer on the surface of the base film containing the aluminized layer. However, during the detachment process of the aluminum plating layer, it is necessary to manually observe the detachment effect, manually adjust the concentration of the cleaning solution and the temperature of the cleaning solution. During the cleaning process, a large amount of adhesive suspended matter floats in the cleaning tank, which is likely to cause the suspended matter to attach to the surface of the cleaned basement membrane for the second ti...
