Why is the water absorption of foam boards so low?

Release time: 2018/12/26 17:11:35

Foam board is widely used in construction engineering. For example, it can be used as a thermal insulation material, which can not only play a thermal insulation effect, but also play a certain waterproof effect. This is because the foam board has a low water absorption rate, which can avoid being exposed to external humidity Environmental impact. So why is the water absorption of foam boards so low ? This is mainly due to the internal structural characteristics of the foam board.

 为什么泡沫板的吸水率很低?

The foam board has a closed-cell structure, which can prevent the penetration of water molecules, even water vapor cannot pass through. If the foam material is mechanically damaged, it will not affect its waterproof performance. It can be maintained by using a tight honeycomb structure. In the state of low water absorption, and there are no gaps on both sides of the foam material, water leakage cannot occur.

Because of this feature, it can also prevent the aging of the foam material and maintain its long-term stability. In addition, the water absorption of the foam is reduced, and the effect of heat insulation will be better. It can prevent the circulation of heat and effectively play the role of heat preservation.

Because the foam board has low water absorption and good permeability resistance, it can effectively avoid problems such as moisture, mold, and shedding on the wall when used in construction projects, and can also play a certain role in protecting the building structure.

In short, the foam board has a low water absorption rate and has a good waterproof effect. In the application of construction engineering, it can not only play a role of heat insulation and protection, but also play a waterproof effect, which is of great significance for extending the service life of the building. Linyi Jinshun Foam is a Linyi foam board manufacturer . The foam board supplied has a variety of specifications, stable performance and a wide range of applications.
