How about the waterproof effect of phenolic insulation board?

Phenolic insulation board is made of phenolic foam material. Phenolic foam material belongs to macromolecular organic hard foam product, which is foamed by thermosetting phenolic resin. Phenolic foam is mainly made of phenolic resin and adhesive. Its molecular density is very small, so it has good waterproof and moisture resistance. The high molecular structure of the phenolic board makes it have a very good closed-cell structure. In the case of large temperature difference between day and night or environmental temperature difference, the phenolic board has a very strong waterproof steam permeability ability. When the requirements for cold insulation are strict, the phenolic board has a good insulation effect on water vapor condensation and penetration. Conventional thermal insulation materials can only be used at room temperature because of their poor closed cell structure. If the environment temperature changes, it needs to be replaced frequently for detection, and the phenolic board can solve this problem very well. This is also the main reason why the phenolic board has such good waterproof and moisture resistance.
The waterproofing of phenolic insulation board is mainly divided into the waterproofing problems of the phenolic insulation board itself and the waterproofing problems of the phenolic insulation board system. The solution to the waterproofing problems of the phenolic insulation board is mainly through the waterproofing treatment of the phenolic insulation board. The traditional waterproofing treatment of the phenolic insulation board is completed by spraying the water repellent of the phenolic insulation board. With the continuous improvement of insulation material enterprise technology, the new waterproof treatment method of phenolic insulation board is to spray adhesive and waterproof phenolic foam foam through spraying equipment when the phenolic insulation board is thrown from the phenolic high-speed centrifuge in the production process. Make phenolic insulation board obtain better waterproof effect.
