请教 这个是不是石棉

乘物以游心

哎，问了N遍的老问题了。

还有这么多人问，简单的回答是：肯定不是石棉。 道听途说的同学不要不懂装懂，幸灾乐祸。

详细的回答：翻以前的帖子吧。。。

隔热层有三种材料：

主要有羊毛的、化纤（Polyester）的是比较高档的，
也有很多是玻璃纤维做的(Glass Wool, Mineral Wool)，
也有用聚乙烯的泡沫（Polyethylene）的。

很多人会把第二种误以为是石棉，其实不然。

Glass Wool是用石英砂加回收玻璃，加热到1450度高温，然后经过细网，吹出来的细丝冷却而成，像用白糖作做棉花糖一样。
这种玻璃纤维，安装人员可能会有皮肤过敏的可能，但是目前并没有证据显示它对人体有什么其他伤害。

而石棉则完全不一样，只是一些很老的房子里才有，而且多数是用来做隔板或屋顶的石棉瓦的，
现在已经不用了。石棉是一些天然的硅酸盐矿石纤维，并非人造的。 吸入的话，可能致癌。
因为它也有不易燃的特性，很多人会与Glass Wool混淆了。

一般来说，对于澳洲的建筑：
Before the mid 1980s, it is highly likely that it would have materials containing asbestos.
Between the mid 1980s and 1990, it is likely that it would have materials containing asbestos.
After 1990, it is highly unlikely it would have materials containing asbestos.
2003年，石棉就被全面禁止在澳洲销售和使用了。

而且，在民用建筑里面，一般都没有没有被用来做Insulation，而是做成了波纹状的石棉瓦或石棉板。
只有一些工业建筑有用松散的石棉作Insulation，还有一些老式热水器里面才有。
Loosely bound materials containing asbestos are not commonly found in domestic houses. They were primarily used in commercial and industrial settings for fire proofing, sound proofing and insulation, but can be found in some old domestic heaters, stoves, hot water systems and associated pipe lagging and in the backing of vinyl and linoleum floor coverings.

LZ是在隔热层里找到的，所以几乎不可能是石棉，
总不可能你们家房子是以前的工业厂房改建的吧？

nfortunately you can't tell by just looking. But in Melbourne it is highly unlikely to be asbestos. There was only one major installer using absestos loose fill and for the most part he worked in the ACT and region and did some on the NSW south coast. He imported his stuff from South Africa over about 10 years in the 70s and 80s.

Testing is the only sure way to know. Most asbestos in the uses described by Smurf are not dangerous so long as they remain undisturbed ie: the fibres are retained within the cementitious or other material they are bound up with. If you cut, drill, sand or otherwise create dust then it becomes extermely dangerous stiff.

As the loose fill insulation was pure asbestos fibres it is highly dangerous at all times - so $75 or so to get test is worth it. As Smurf said though arrange it yourself, but take the usual precautions with masks etc and double bagging.

I never enter a roof space without a mask and mostly wear good protective clothing that I remove and wash afterwards. Roofs are full of dust of various types and glass fibres and dust generally are not good for human airways.

Plenty of web info on asbestos - some of the best on insulation is on the ACT site as it had the most houses done with loose fill.

我家的也是這種，應該不是石綿，最近ebay上買了新的蓋在上面，

白云，我们家和你们一样，棉絮一样的东西，然后装了新的盖在上面，今天突然看到这个帖子

有点担心，你确认那个棉絮不是石棉啊？
