石膏板的防火性能怎么樣? 發(fa)布時間: 2018-04-13
石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)板(ban)(ban)的(de)(de)防火(huo)性能怎么樣? 紙面(mian)(mian)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)板(ban)(ban)也越來越流行,在(zai)家具裝飾(shi)過(guo)(guo)程中(zhong)紙面(mian)(mian)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)板(ban)(ban)也起到(dao)了非同小可的(de)(de)作(zuo)用(yong),那么紙面(mian)(mian)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)板(ban)(ban)的(de)(de)防火(huo)性能如何(he)呢?會不會因(yin)為是紙面(mian)(mian)的(de)(de)而效果更(geng)差呢? 石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)板(ban)(ban)的(de)(de)結(jie)晶水(shui)(shui)是它防火(huo)的(de)(de)一個重(zhong)要(yao)原因(yin)。石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)板(ban)(ban)受火(huo)時,先是板(ban)(ban)芯中(zhong)的(de)(de)游離水(shui)(shui)分(fen)蒸發出(chu)來,吸(xi)收少量(liang)的(de)(de)熱量(liang),降低板(ban)(ban)周的(de)(de)溫(wen)度(du)。當溫(wen)度(du)繼續升(sheng)高,二水(shui)(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)的(de)(de)結(jie)晶水(shui)(shui)開始(shi)脫離,分(fen)解成石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)和(he)水(shui)(shui)分(fen),這個過(guo)(guo)程需要(yao)吸(xi)收大量(liang)的(de)(de)熱量(liang),可以在(zai)比較長(chang)的(de)(de)時間里影(ying)響(xiang)板(ban)(ban)面(mian)(mian)四周的(de)(de)溫(wen)...
