The aluminum foam produced by Henan Chalco Aluminum by innovative technology is divided into melting, melt pretreatment, melt viscosity increasing, additive stirring, insulation foaming, cooling, cutting, sheet metal post-processing, storage, packaging and other processes. Non-toxic and harmless metal materials are used in each process, which can realize 100% recycling of waste and recycled products.
With the characteristics of noise reduction, heat insulation, strong impact resistance, electromagnetic shielding, and spherical interworking cavity with aesthetic characteristics, Henan Chalco aluminum foam can be widely used in building insulation and insulation, swimming hall sound absorption wall, foam aluminum building curtain wall, sound insulation floor, entertainment places, and artistic buildings, hall, ceiling, wall decoration, etc.
