目前工程上常用的保温材料,如玻璃棉、岩棉、矿棉以及普通泡沫石棉等,其容重轻、不燃和保温性能好的特性都差不多。但它们都有个共同的缺陷,即耐水性差,极易吸水。而作为保温绝热材料,一旦吸水过量,或使导热系数急剧升高,其绝热性能受到破坏;或因冲淋侵蚀而使外观尺寸改变(如造成塌陷等)。这 At present, insulation materials commonly used in engineering, such as glass wool, rock wool, mineral wool, and ordinary foam asbestos, have similar properties in terms of light weight, non-flammability, and good insulation properties. However, they all have a common defect: they have poor water resistance and are prone to water absorption. As a heat insulating material, once the water is absorbed excessively, or the thermal conductivity is drastically increased, its thermal insulation property is damaged; or the size of the appearance is changed due to shower erosion (such as causing collapse, etc.).
