Fireproof building materials
Every time read those news
Always see the building fire
Therefore, there is a kind of building material called fireproof material.
Fireproof materials are not absolutely fireproof,
it is at within a certain period of time, it can prevent burning.
For example, 1 hour fireproof building materials / 2 hours fireproof building materials / 4 hours fireproof building materials / 8 hours fireproof building materials!
It is necessary to pay attention to the experimental report and manual of fireproof building materials. When the manufacturer writes, most of them avoid heavy weight. It is best to choose the report issued by the public unit.
After the fireproof material exceeds the fire prevention time limit, it will still catch fire. At this time, you should pay attention to the smoke damage caused by the fire. Some fireproof materials are very cheap, but the smoke damage after the fire is very big, not to be careless!
防火的建築材料
每次看新聞
總是會看到建築失火
故而建築材料有一種被稱之為防火材料
防火材料並不是絕對的防火
而是在一定的時間之內,可以防止燃燒
比如1小時防火建材/2小時防火建材/4小時防火建材/8小時防火建材!
要注意的是防火建材的實驗報告和使用手冊,廠商在編寫的時候,大都避重就輕,最好選擇公立單位所開立的報告.
防火材料在超過防火時限之後,仍會起火,這時候,你就要注意他在起火之後所產生的煙害了,有的防火材料雖然很便宜,但起火之後的煙害卻很大,不可不慎!
