Construction technology of polyurethane exterior wall insulation works a construction preparation 1.1 polyurethane foam construction machinery and equipment to prepare the polyurethane foam in this project the main equipment of choice for US imports Colas polyurethane foam equipment, the system is a high pressure spray foam equipment . Because the material high pressure spraying equipment, high-speed crash in a small space of the mixing chamber and vigorous rotation, mixing very full. High-speed movement of materials in the mouth to form a fine mist of droplets spray gun evenly sprayed onto the object surface. 1.2 polyurethane insulation materials prepared for a combination of polyether urethane and isocyanate mixed reaction to form with a waterproof and thermal insulation, and other functions of rigid foam material. Black material imported / domestic, white material-based production company. 2, the construction requirements: 5cm thick exterior wall painting, one of the flatness of ± 1cm aluminum plate, requires two to three times to complete spraying, spraying each no more than 3cm thick, Master roof foam density greater than 40kg / m3, obturator rate greater than 90%, the difference between the positive and negative surfaces of 1cm. Turn on the surrounded height 50cm (can be turned highly waterproof floor under the walls), the thickness of 3cm. Spraying can be done after the completion of a layer of mortar layer (waterproof slope) metal one plate on the surface, then you can do the waterproofing. 3. Prepare 3.1 before entering the construction technology, project managers and technical personnel should be familiar with the drawings and design changes, etc., clear the construction site. 3.2 pairs of construction workers and safety tests, technical tests. 3.3 During the construction work to do around the pollution prevention, polyurethane spray is easy to fly with the wind, pollution and other objects and vehicles. The primary wall construction process to clean spray polyurethane insulation materials first pass (about 1cm thickness control in layered continue spraying polyurethane insulation until it meets the requirements for inspection of polyurethane insulation thickness of polyurethane insulation thickness trimmed exterior wall decoration one board, also known as Integration of the finished wall insulation board, each patent according to the manufacturer according to the column, said: one energy-saving decorative board insulation board, composite insulation decorative panels, insulation decorative plates, decorative plates and other wall insulation, preformed at the factory have wall insulation sheet functions. insulation decorative plate composite material made from insulation materials and decoration, as posted outside the walls hung in the building, with insulation and decorative features. The fire protection requirements, are generally closed and non-closed type.
