保温资料要防潮

Moisture-proof insulation materials

保温隔热资料次要是起保平和隔热,普通都是体轻、疏松的物质,呈多孔状、纤维状或粉末状,外部含有少量运动的空气。由于空气是热的不良导体,这些密闭的空气起着良好的保温作用。

The heat preservation and insulation materials are mainly flattening and insulation. They are generally light and loose materials, which are porous, fibrous or powdery, and contain a small amount of moving air outside. Because air is a bad conductor of heat, these airtight air plays a good thermal insulation role.

但假如保温资料受潮,即水分侵入保温资料外部,则其中的一些空气爲水分所取代。水的导热系数要比运动的空气大25倍,假如其中的水分再受解冻成冰,则冰的导热系数要比运动的空气大100倍。由此可见,受潮的保温资料,导热功能分明添加,而保温功能则大爲降低,资料的含湿率越高,则保温功能降低愈多。

But if the heat preservation data is damp, that is, water intrudes into the outside of the heat preservation data, then some of the air is replaced by water. The thermal conductivity of water is 25 times greater than that of moving air. If the water is thawed into ice, the thermal conductivity of ice is 100 times greater than that of moving air. It can be seen that the heat conduction function is clearly added, while the heat preservation function is greatly reduced. The higher the moisture content of the data, the more the heat preservation function is reduced.

A1级防火保温材料

因而,像水泥发泡保温板这些保温资料在运输贮存和运用进程中,必需坚持枯燥形态,思索靠防潮抗冻,这样资料才干坚持其任务功能的期限,即耐久性。

Therefore, in the process of transportation, storage and operation, thermal insulation materials such as cement foam insulation board must adhere to the dry form and think about moisture-proof and freeze-proof, so that the data can adhere to the duration of its task function, that is, durability.
