其中使用得为普遍的保温隔热材料,无机材料有膨胀珍珠岩、加气混凝土、岩棉、玻璃棉等,有机材料有聚苯乙烯泡沫塑料、聚氨酯泡沫塑料等。这些材料保温隔热效能的优劣,主要由材料热传导性能的高低(其指标为导热系数)所决定。材料的热传导愈难(即导热系数愈小),其保温隔热性能便愈好。一般地说,保温隔热材料的共同特点是轻质、疏松,呈多孔状或纤维状,以其内部不流动的空气来阻隔热的传导。其中无机材料有不燃、使用温度宽、耐化学腐蚀性较好等特点,有机材料有强度较高、吸水率较低、不透水性较佳等特色。


在上述常用保温隔热材料中,膨胀珍珠岩、岩棉、玻璃棉、聚苯乙烯泡沫塑料、聚氨酯泡沫塑料等材料的导热系数都比较小,虽高低也有差别,但相差不算很大,均属于高效绝热材料,但无承重功能;加气混凝土的保温隔热性能优于粘土砖和普通混凝土等建筑材料,但低于上述高效绝热材料较多。大连保温板安徽快3走势图指出由于加气混凝土为水泥、石灰、石英砂、粉煤灰、炉渣和发泡剂铝粉等,通过高压或常压蒸养制成,密度较大,干容重为每立方米300—700公斤左右,可利用工业废料,有一定承重能力,能砌筑单一墙体,兼有保温及承重作用。
