The phenomenon of detachment of external wall insulation materials is due to installation and material issues. It is necessary to fully consider the impact of the environment on the service life of external wall insulation materials, such as expansion after heat absorption and reduced adhesion caused by rainwater erosion.

In exterior wall insulation materials, we know that exterior wall insulation boards are mainly composed of adhesive layers, insulation layers, plaster layers, decorative layers, and accessories. The adhesive layer is located between the bottom layer and the surface layer, and the upper layer and the lower layer are firmly adhered to the gel material. The filler mainly comes from inorganic substances. To avoid and reduce the heat loss of the turbine to the environment, a layer of insulation material is laid on the outer surface of the turbine and pipeline. Its main fillers are rock wool fibers and a certain amount of organic matter, moisture, and binder. The decorative layer should be made of lightweight functional coatings, such as decorative mortar, decorative mortar, or water-based exterior wall coatings, to maintain the lightweight characteristics of the rock wool board and increase its aesthetic appeal.

In terms of exterior wall insulation material accessories, we mainly choose various coatings. On the one hand, the color of the surface of the rock wool board for exterior wall insulation material increases, making it suitable for any environment and playing a role in flame retardant insulation to a certain extent. Hard exterior wall insulation materials have moisture-proof and waterproof properties. Hard external insulation materials with a closed cell rate greater than 95% are hydrophobic materials. It does not increase thermal conductivity by absorbing moisture, nor does it cause wall leakage.

The hard exterior wall insulation materials produced by Huaneng Company have the characteristics of fire resistance, flame retardancy, and high temperature resistance. After adding flame retardants, the external wall insulation material is a non flammable self extinguishing material. Its softening point can reach over 250 degrees Celsius, and it only decomposes at high temperatures. In addition, the outer wall insulating material forms a carbonized layer on the foam surface when burning. This layer of carbonization helps to isolate the foam below, which can be effective. Prevent the spread of fire. In addition, external wall insulation materials do not produce harmful gases at high temperatures.
