Research on recycling and regenerating process and technology of waste building aluminum formwork
The market share of building aluminum formwork in China has exceeded ten million tons,and the annual recyclable amount of waste building aluminum formwork has reached one million tons.In this paper,the recycling and regenerating process and technologies of waste building aluminum formwork were introduced,including the pretreatment and melting of waste building aluminum formwork and extrusion forming of new building aluminum formwork.The key technologies such as pre-treatment,melt purification and refinement,design of extrusion dies,and control of extrusion processes can realized grade preservation and regeneration of waste building aluminum formwork,which is of great significance for reducing production costs,saving resources,reducing emissions,and protecting the environment.
