微孔硅酸钙保温材料是一种新型的保温材料,它具有容重轻、导热系数小、强度高、使用温度高等优点,目前己广泛应用于石油、化工.电力等部门的管道和设备保温工程中。但这种材料的最大缺点是吸水性强,用水泥砂浆抹面根本无法抹上,因而给抹面层的施工带来困难。以往补救的方法是,在微孔硅酸钙的表面涂一层硅油,以降低硅酸钙的吸水性。
Microporous calcium silicate insulation material is a new type of insulation material. It has the advantages of light weight, low thermal conductivity, high strength, and high use temperature. It has been widely used in petroleum, chemical, electric power and other sectors of the pipeline and equipment insulation engineering. in. However, the biggest drawback of this kind of material is its strong water absorption, which can’t be wiped with cement mortar, which makes it difficult to apply the finish. The previous remedy was to apply a layer of silicone oil on the surface of the microporous calcium silicate to reduce the water absorption of the calcium silicate.
