据有关资料报道,美国密执安州州立大学材料加工学会开发出一种回收铝后的废料的新用途,用回收铝后废物代替纯铝粉制造泡沫混凝土。它不仅使传统工艺大大节省费用,而且制得的泡沫混凝土具有与纯铝粉末制的泡沫混凝土相同的强度。传统的泡沫混凝土制造工艺是用细的金属铝粉末与氢氧化物反应生成氢气,形成细的气泡后,使混凝土变成泡沫状多孔体,但是用铝箔废料和回收铝后废料作为泡沫剂时,但是用
According to relevant information, the material processing society of Michigan State University in the United States has developed a new use of recycled aluminum waste, using recycled aluminum instead of pure aluminum powder to produce foamed concrete. Not only does it save a lot of money for the traditional process, but also the foamed concrete produced has the same strength as foamed concrete made of pure aluminum powder. The traditional foamed concrete manufacturing process uses fine metal aluminum powder to react with hydroxides to produce hydrogen. After the formation of fine bubbles, the concrete turns into a foamy porous body. However, when using aluminum foil scrap and recycling aluminum scrap as foaming agent, But with
