China Supplier Decorative PU/Rockwool Foam Sandwich Board Insulation Protection Aluminum Composite Metal Carving Exterior Wall Panel

Aluminum composite sandwich honeycomb panel, also known as aluminum honeycomb composite panel, is a new type of lightweight, high-strength, high-stability composite material, widely used in construction, transportation, ships and other fields. Due to the special structure of the honeycomb aluminum core, the aluminum composite sandwich honeycomb panel has a low weight while maintaining high strength, which reduces the load-bearing burden of the building. The interior of the honeycomb aluminum core is full of air, forming a good heat insulation layer, making the aluminum composite sandwich honeycomb panel has excellent heat insulation and thermal insulation performance.

Aluminum sandwich panels are prepared by various methods, including adhesive connection method, laser welding connection method, sewing connection method and so on. Among them, the adhesive connection method is a simple and convenient method, but there are lower strength and easy delamination under high temperature and corrosive conditions to destroy the shortcomings; laser welding connection method is a complex process, the production time is longer; stitching connection method is a complex production process and the strength of the connection is low.
