陶瓷棉與玻璃棉哪個更保溫

前(qian)(qian)兩(liang)個是(shi)保(bao)溫材(cai)料(liao)(liao)，石棉(mian)(mian)(mian)(mian)是(shi)密封，陶瓷也屬保(bao)溫材(cai)料(liao)(liao)石棉(mian)(mian)(mian)(mian)是(shi)天然(ran)的(de)纖(xian)(xian)維狀硅(gui)酸鹽材(cai)料(liao)(liao)，不(bu)燃(ran)，玻璃棉(mian)(mian)(mian)(mian)氈可做(zuo)保(bao)溫絕(jue)熱材(cai)料(liao)(liao)，但其(qi)中含有極小的(de)纖(xian)(xian)維，容(rong)易被人體(ti)吸收，有致(zhi)癌性，國際上開始(shi)禁用。礦棉(mian)(mian)(mian)(mian)是(shi)由硅(gui)酸鹽熔(rong)融物制(zhi)得的(de)蓬松狀短細(xi)纖(xian)(xian)維。按所(suo)用原料(liao)(liao)可分為(wei)巖(yan)(yan)棉(mian)(mian)(mian)(mian)和礦渣(zha)棉(mian)(mian)(mian)(mian)兩(liang)大類。前(qian)(qian)者以火成(cheng)巖(yan)(yan)、變質巖(yan)(yan)與(yu)(yu)沉積巖(yan)(yan)等(deng)(deng)天然(ran)巖(yan)(yan)石為(wei)主(zhu)(zhu)要(yao)原料(liao)(liao)，常(chang)用玄(xuan)武巖(yan)(yan)、輝(hui)綠巖(yan)(yan)、角(jiao)閃巖(yan)(yan)與(yu)(yu)泥灰巖(yan)(yan)等(deng)(deng);后者以某些(xie)冶(ye)金礦渣(zha)為(wei)主(zhu)(zhu)要(yao)原料(liao)(liao),如鐵、磷(lin)、鎳、鉻、鉛、銅、錳、鈦、鋅等(deng)(deng)礦渣(zha)。玻璃棉(mian)(mian)(mian)(mian)是(shi)是(shi)一種人造(zao)無機(ji)纖(xian)(xian)維。采用石英砂、石灰石、白(bai)云石等(deng)(deng)天然(ran)礦石為(wei)主(zhu)(zhu)要(yao)原料(liao)(liao)，配合一些(xie)純堿、硼砂等(deng)(deng)化工原料(liao)(liao)熔(rong)成(cheng)玻璃。在融化狀態下，借助外力吹制(zhi)式甩成(cheng)絮狀細(xi)纖(xian)(xian)維。
