补充资料：透气度
分子式：
CAS号：
性质：(一)在常温和一定的压差下，气体透过耐火制品的能力。常用的计量单位为μm2。即在1Pa的压差下，黏度为1Pa·s的气体透过面积为1m2、厚1m制品的气体体积流量为1m3/s时，透气度就为1m2(1m2=1012μm2)。耐火制品的透气度取决于其本身的致密程度，特别是与其中贯通气孔存在的特征有直接关系。它是耐火材料中一个较重要的质量指标。(二)在一定面积、一定压差(或真空度)下，每分钟透过试样的空气量，或透过100ml空气所需的时间，以ml/min(肖伯尔仪)或s/100ml(葛尔莱仪)表示。国际标准则以m/(Pa·s)表示。纸张是一种多孔性材料，气孔率约有70％。但真空率(透过纸页的孔眼)只占气孔率的1.6％。透气度是印刷纸、书写纸、浸渍原纸、纸袋纸、卷烟纸以及过滤用纸的一项重要质量指标。
