除了他说的那些传统隔热方法外,现在还流行框架做好了之后喷射泡沫剂,凝固之后就成了一道隔热层,从天花 ...
( b" o M$ Y8 M; \+ b室内和室外用的材料是不一样的,室内用的是聚酰胺,这种东西稳定无毒。以前冰箱用的白色的泡沫是有致癌的东西放出来的。国内好像还在大量的应用,这边好像很难见到了,但在包装材料上还可以见到。。不过我个人始终对有机材料有怀疑,聚酰胺只不过结构更为稳定罢了,理论上应该还是有挥发的,只不过可能在现在仪器检测下限。另外FDA或官方机构的东西也不能全信,三聚氰胺就是FDA认为无毒的东西。我个人对有氮的有机化学物质和苯环类的东西始终用畏惧感。哈哈哈,我知道这不是科学的精神。
