Spray hard foam polyurethane and external wall insulation are a new type of building energy-saving technology, with three technological innovations.
1.Using the polyurethane moisture-proof primer to stop the treatment of the base wall surface, improving the adhesion between the polyurethane and the base wall surface, and effectively avoiding quality problems such as foaming, embrittlement, chalking, and layering;
2.Using the polyurethane interface mortar to stop the treatment of the polyurethane insulation layer surface, ensuring the bonding strength of the inorganic leveling materials and the polyurethane insulation layer, and preventing the occurrence of undesirable phenomena such as bulging, loosening and cracking;
3. Xu'an used rubber powder poly * particle insulation slurry to stop the leveling treatment of the polyurethane insulation layer, reducing the load on the insulation layer, improving the system's fire performance, and the data performance has also completed a layer-by-layer transition, which is beneficial to the system. Anti-cracking, and can strengthen the insulation effect.
