CCM double sided sealed layer laminating method

Abstract

The invention discloses a CCM double sided sealed layer laminating method, which comprises following steps: CCM body preparation, top layer sealing, material lamination, bottom layer sealing, infraredpositioning machine calibration, pressure roller double sided rolling, catalytic coating sealing, CCM standing, top layer roller winding, top layer film pasting, bottom layer roller winding, bottom layer film pasting, CCM primary examination, second processing and recovering, disqualified product recovering, CCM trimming, CCM polishing, quality detection, and CCM packaging. The method has the advantages that in the CCM double sided sealed layer laminating method, steps of infrared positioning machine calibration, CCM trimming, CCM polishing, and CCM packaging are added; the step of infrared positioning machine calibration can maximally improve the precision of double sided sealed layer lamination and calibration, the problem of large deviation in double sided sealed layer lamination is solved; CCM trimming and CCM polishing can maximally optimize the CCM after double sided sealed layer lamination; in the CCM packaging step, CCM is packed in vacuum, and thus the CCM is maximally protected during the long process of transportation and storage.

Description

technical field [0001] The invention relates to the field of catalyst-coated membranes (CCM for short), in particular to a bonding method for double-sided sealing layers of CCMs. Background technique [0002] The CCM double-sided sealing layer bonding method is to attach a sealing layer to the catalytic coating on both sides of the CCM before the actual use of the CCM to protect the CCM for a long time, so that the CCM catalytic coating is well protected. It can guarantee the performance of CCM to the greatest extent when using it. [0003] The current CCM double-sided sealing layer bonding method has the following shortcomings. It cannot calibrate the accuracy of the double-sided sealing layer to the greatest extent. After the double-sided sealing layer is bonded, it may increase the problem of excessive deviation of the sealing layer. , and it is not possible to perform trimming cutting, chamfering and vacuum packaging after the CCM double-sided sealing layer is attached,...

Problems solved by technology

[0003] The current CCM double-sided sealing layer bonding method has the following shortcomings. It cannot calibrate the accuracy of the double-sided sealing layer to the greatest extent. After the double-sided sealing layer is bonded, it may increase the problem of excessive deviation of the sealing layer. , and it is not possible to perform trimming cutting, chamfering and vacuum packaging after the CCM double-sided sealing layer is pasted, which reduces the maximum product optimization and protection of the CCM after the CCM double-sided sealing layer is pasted.
