利用"三废"制轻型保温隔热建筑材料

塑料的问世给人们的日常生活带来了极大方便的同时,也给人类居住环境造成很大破坏。人们使用后的聚苯乙烯泡沫包装盒(板)和塑料袋随处可见,形成了难以消除的“白色污染”。还有工业废渣到处堆积如山,没有得到充分利用。针对这种情况．笔者为了开发这些“三废”材料的新用途．利用泡沫塑料和炉渣表观密度小、空隙率大、保温隔热性能好等特性,研制了一种轻型保温隔热建筑材料,经过实验取得了良好效果。

"Three-waste Materials" Can Be Utilized to Make a Light Warm-keeping and Heat-free Building Material

The invention of plastic has made people's life convenient,but it brings a great threat to our envinonment.The packing boxes or boards made of polystyrene foam and plastic bags discarded by people everywhere lead to "white pollution". Dregs poured out of industrial boilers are piled like hills in many places. This paper describes a new way of making a light warm-keeping and heat-free building material by making use of the these waste materials because of their characters of low surface density, big gap rate and the strong insulation. The experiments and tests have shown that the effect is good.
