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

The honeycomb aluminum core in the middle can effectively isolate the sound, making the aluminum composite sandwich honeycomb panel has good sound insulation effect. Aluminum composite sandwich honeycomb panel has strong impact resistance, can resist external impact without deformation or damage. Aluminum composite honeycomb panels can be cut, bent and other processing as needed, and easy and fast installation.

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 composite sandwich honeycomb panel by the upper and lower layers of aluminum and the middle of the honeycomb aluminum core through a special bonding technology composite. The surface aluminum plate is usually 0.5mm to 1.5mm thickness of aluminum alloy sheet, with good fire, weather and corrosion resistance. The intermediate honeycomb aluminum core consists of many hexagonal aluminum honeycomb holes parallel to each other, which not only reduce the overall weight but also enhance the stability and rigidity of the structure. The bonding layer uses a high-strength adhesive or adhesive film to firmly bond the surface aluminum panel and the honeycomb aluminum core together to form a whole.

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.
