The Phenolic board is made of phenolic foam material, which is a polymer organic rigid aluminum foil foam product and is foamed from thermosetting phenolic resin. The Ventilation duct heat shield is widely used in developed countries. According to statistical data and literature records, 40% of the fire insulation and sound insulation materials in the United States are phenolic resins. The United Kingdom, Western Europe, and the Middle East stipulate that phenolic foam insulation materials are preferred for new projects. The construction departments in France and the Nordic region believe that only phenolic foam insulation materials have good fire performance. Russia and Eastern Europe also widely use phenolic foam insulation materials for public buildings and high-rise buildings. Japan even promulgated the "Phenolic foam as a standard building fire-resistant material" decree. Next, let's take a look at the architectural description and waterproofing of the Phenolic board. Here are some answers.
Here is the content list:

The waterproof problem of Phenolic board.
The architecture of the Phenolic board is mainly composed of: a bonding layer, insulation layer, plastering layer, finishing layer, and accessories. The adhesive layer belongs to the building and is between the bottom layer and the surface layer. The upper and lower layers are mainly bonded together firmly with cementitious materials. The main source of the filler is inorganic matter. Insulation layer to avoid and reduce the heat loss of the steam turbine to the environment, the insulation material layer laid on the outer surface of the steam turbine and pipelines is mainly filled with rock wool fiber and a certain amount of organic matter, moisture, and adhesives. The finishing layer should use lightweight functional coatings such as finishing mortar and embellishment mortar, or water-based exterior wall paint with excellent air permeability so that the Fire insulation board can maintain its lightweight and increase its aesthetics.
First of all, the so-called waterproof problem of the Phenolic board is mainly divided into the waterproof problem of the Phenolic board itself and the waterproof problem of the Phenolic board system. The waterproofing of the Phenolic board is mainly solved by waterproofing the Phenolic board. The old-fashioned waterproofing of the Phenolic board is to spray a water-repellent agent on the Phenolic board. With the continuous improvement of the technology of thermal insulation materials companies, the new method of waterproofing the External wall fire insulation board is to spray the adhesive and waterproofing agent on the phenolic foam through the spraying equipment when the high-speed centrifuge throws out the phenolic foam during the production of the Phenolic board so that the Phenolic board to obtain the better waterproof effect. Due to the uneven waterproof effect of the old-fashioned Phenolic board, it is easy for the Phenolic board to be installed on the wall, and the insulation system cannot meet the 25-year life requirement at all. And the new Phenolic board waterproof treatment can fully meet the standard.
The waterproof problem of the Phenolic board insulation system is more complicated. In general, the factors that may affect the waterproof performance of the Phenolic board insulation system are as follows:
1. The quality of the waterproof interface agent on the base surface of the wall.
2. The effect of the waterproof interface agent on the Phenolic board itself.
3. The hydrophobicity of the mortar used for Foam sandwich panel plastering.
4. The details of the window frames, air-conditioning holes, parapets, etc. of the building are waterproofed and enhanced.
