Construction of phenolic board

Phenolic foam board insulation for interior and exterior walls is generally achieved through mortar bonding or nail bonding methods. Starting from the supporting part from bottom to top, the phenolic board can be adhered to the wall surface with polymer crack bonding mortar. The bonding area should be greater than 35%, and for the first layer, it should be greater than 50%. When the outer protective layer is relatively heavy, 4 to 6 insulation nails should be nailed per square meter.

The protective layer construction can be carried out 24 hours after the machine is parked after bonding. The external surface impact construction can be carried out after another 24 hours. The thickness and density of insulation boards in areas north of the Yellow River should be no less than 4cm and 50kg/m ³ respectively. It should be thickened in cold regions. Composite material insulation decorative panels integrate building insulation and decoration.

Factory production. The phenolic board should be firmly bonded to the decorative board. The construction technical plan adopts light steel keel. The composite material insulation decorative board is hung on the keel and should be fixed. It is essential to handle the gaps between the circuit boards properly to prevent leakage. Non-transparent and curtain wall panels can be bonded to the inner panels of Chinese curtain walls or fixed to a wall surface. A closed space is formed between the wall panels and the curtain wall panels. Fireproof isolation belts can be spaced at the required intervals as per the design requirements, and the spacing should not be less than 30 centimeters.

The newly produced phenolic board can generally be used after 21 days of curing. The phenolic foam resin colored steel phenolic composite board room temperature composite material sprayed with the insulation layer of colored steel phenolic composite board overcomes the shortcomings of the fire protection requirements of flammable materials such as polyurethane and polystyrene foam, and is developing vigorously with the new high flame retardant new look The produced spray-coated composite material has solved the problem of poor adhesion between phenolic foam and color steel plates, marking a major breakthrough in the phenolic foam industry. The application research scope of the room-temperature foaming resin technology can be used to replace polyurethane in the insulation of thermal pipelines, buried pipes and solar water tanks. Interlayer insulation for fireproof doors, garage doors, security doors, etc.

The characteristics of phenolic composite system air ducts and phenolic composite control air ducts: Good flame retardancy, no need to add any other flame retardants to the material, it is a difficult-to-burn material. In case of fire, it does not spread the fire, and the air duct design only undergoes carbonization. Environmentally friendly and hygienic, it uses fluorine-free foam, which will not damage the ozone layer, does not release harmful substances, is non-toxic and odorless, and is easy to clean. The insulation material has excellent performance and strong adaptability to temperature, suitable for various social environments ranging from -60 to 150℃.

It can also be applied to various types of buildings, as well as civil, industrial, military and other different structures. It does not absorb water, is moisture-proof, chemically stable and will not decompose or mold. The lifespan can generally reach more than twenty years. The energy-saving technology is particularly remarkable, saving 70% of the energy content compared with galvanized iron plates.
