This paper introduces how to choose adhesive sandwich film for domestic production of composite diaphragm

(1) First of all, it is necessary to consider which kind of medium the composite membrane is resistant to, generally water or liquefied gas and other gases, and select different adhesives according to different media.

(2) Bond strength

(3) Temperature resistance refers to the temperature range that the fully cured adhesive layer can bear

(4) The curing time of the composite membrane can be divided into initial setting time and full curing time. It refers to the time required for the adhesive to change into solid glue at room temperature. The proper choice of adhesive can achieve the desired effect and improve the performance of the composite membrane.
