Description

Technical Field

[0001] This utility model relates to the field of composite membrane production, specifically a composite membrane production apparatus. Background Technology

[0002] Composite films are multilayer composite materials made by bonding two or more thin films together through a specific composite process. They are mainly composed of a substrate, adhesive, and processing aids, and have a variety of excellent performance characteristics and applications. After lamination, the products need to be cured in a curing chamber to ensure that the adhesive is fully cured and reaches the expected bonding strength. The curing process is also one of the important production steps of composite films.

[0003] The existing curing method is thermal curing, which involves heating the material at high temperatures to cause cross-linking of the molecular chains in the material, thereby enhancing the strength and stability of the film. However, existing curing equipment is equipped with inlets and outlets for feeding and discharging. The inlets and outlets are open when heating and curing the composite film, and some of the heat generated by the heating tubes will dissipate, resulting in heat waste and failing to fully utilize the heat of the curing machine.
