External wall application

1. Product features

(1) Hard foam polyurethane has good insulation effect. Hard foam polyurethane is an excellent insulation material with a thermal conductivity of 0.024W/(m · K); Spraying forms a continuous insulation layer、 ensuring the integrity of the insulation material and the wall and effectively blocking the thermal bridge (2) Dual insulation effect of polyurethane insulation and adhesive powder polystyrene particles. Composite the two together through an interface agent to exert their respective effects. The excellent protective performance of the fireproof and breathable transition layer of adhesive powder polystyrene particles. The adhesive powder polystyrene particle slurry contains a large amount of inorganic materials. After being composite on the surface of the polyurethane rigid foam insulation layer、 it not only has a good leveling effect、 but also has a protective effect on the rigid foam polyurethane insulation layer: it effectively prevents the aging effect of ultraviolet radiation on the polyurethane layer; Make up for the shortcomings of on-site spraying of polyurethane insulation materials in local areas such as doors and windows、 avoid the generation of thermal bridges、 and enhance the insulation effect of the system; The crack resistance technology route that conforms to the flexible gradual release of stress layer by layer can effectively prevent the occurrence of cracks in the protective surface layer、 and can improve the stability and durability of the system; Reducing the thickness of polyurethane insulation layer can save engineering costs and reduce costs; Effectively blocking the impact of fire sources on the hard foam polyurethane insulation layer (3) No cavity structure、 strong wind pressure resistance. The sprayed hard foam polyurethane insulation layer is firmly combined with the base wall、 forming an organic whole with no joints or cavities、 reducing the damage of wind pressure、 especially negative wind pressure、 to the external insulation system of high-rise building walls (4) Excellent resistance to damp heat and waterproof performance. Hard foam polyurethane has excellent insulation performance and unique impermeability、 truly combining the two functions of waterproofing and insulation、 and can be completed in one go during construction. It can replace traditional waterproof and insulation layers and be widely used for roof and wall insulation (5) Excellent fire resistance. Polyurethane、 with the addition of flame retardants、 is a flame retardant and self-extinguishing material. The surface of the polyurethane and the side of the door and window are tightly wrapped with B1 grade adhesive powder polystyrene particle slurry with combustion performance. When exposed to fire and heat、 the heat is transferred to the interior slowly and less、 and the heat is concentrated on the surface of the adhesive powder polystyrene particle slurry layer、 which is beneficial for improving the fire resistance of the insulation layer

(6) has good construction performance. Hard foam polyurethane spraying adopts mechanized operation、 with fast construction speed and high efficiency. To ensure the straightness of the internal and external corners、 it is advisable to use the method of pasting polyurethane prefabricated blocks to reduce material loss、 which is beneficial for the subsequent process of straightening the internal and external corners and edges、 and improving the overall construction quality and efficiency (7) Good environmental friendliness. The insulation material itself has high chemical stability and adopts fluorine-free products
