Abstract
Description
Technical Field
[0001] This utility model relates to the field of thin film composite equipment technology, and in particular to a three-in-one composite machine that can meet various coating processes. Background Technology
[0002] Solvent-free three-in-one lamination refers to a process that completes the lamination of three substrates in a single solvent-free step. It boasts advantages such as high production efficiency, high yield, and avoidance of some drawbacks of two-layer lamination processes, leading to its expanding applications. Conventional solvent-free three-in-one lamination processes involve applying adhesive twice, separately to the surfaces of two substrates. However, in various real-world applications, there are situations where the surface and inner layers of the three-layer composite structure cannot be glued, or the glue application is ineffective. To achieve such three-layer composite structures, it is necessary to develop a process that allows for adhesive application to both sides of the middle layer during the lamination process.
