A method and equipment for dealumination of base film

Abstract

A method for dealuminating a base film, which is characterized in that it includes the following steps: a. Send the base film containing an aluminum-plated layer on the surface into a cleaning solution to wash the aluminum; b. Send the above-mentioned base film into clean water for cleaning; c. , dry the above base film. The base film dealumination equipment used in the above-mentioned base film dealumination method includes a cleaning tank, a base film rewinding and unwinding mechanism, and an oven. The cleaning tank is divided into a cleaning liquid tank and a clean water tank by partitions. The oven is located in the cleaning area. Behind the tank, the base film rewinding and unwinding mechanism passes through the cleaning tank and the oven in sequence, and is characterized in that: the base film dealumination equipment also includes a cleaning solution circulation filtering mechanism. The present invention adds a cleaning solution circulation filtering mechanism to the alkali solution circulation system, so that the cleaning solution at the top overflows from the cleaning liquid tank into the cleaning solution circulation filtering mechanism, the suspended matter therein is filtered, and the filtered cleaning solution passes through the circulation Return to the cleaning solution tank again to continue use, which improves the utilization efficiency of the cleaning solution.

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...
