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 Tai'an stone one board, 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 coating, calcium silicate board flatness of ± 1cm stone one board, requiring two to three times spraying is completed, spray each one no more than 3cm thick stone panels, Master roof foam density greater than 40kg / m3, a closed cell ratio of 90%, the surface difference of plus or minus 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) 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 thin stone insulation decorative panel installation - sticky hang one thin insulation decorative stone panels with a unique sticky, hanging one of the installation: Six fire insulation decorative panels wrapped inorganic polymer mortar to form a complete box structure, insulation material is filled in the box inside the body insulation materials and thin stone and exterior are not in direct contact. During installation, special cement paste adhesive strip style or point the way through the column, basically full of sticky, increasing the paste area, so fire insulation decorative panels and building exterior Wall uniform force, bonded together to form an inorganic polymer mortar box structure, bonding with constituent cement adhesives and building facades, the expansion coefficient are basically the same, form a perfect whole, to ensure that the thin stone same fire insulation composite panels and architectural life. When bonded to each other to avoid the different nature of the materials, products cracking due to expansion coefficient, thermal conductivity, weather and other factors, loss, accidents. At the same time, fixed in thin stone built-in aluminum and stainless steel L-shaped pendant pieces combined with each other on the nail through a dedicated wall insulation in buildings. Not only can adjust the mounting position of general red fire insulation decorative panels within a certain range, so that the fire insulation decorative The mounting plate is more convenient. And to make installation and paste the perfect combination of mechanical connections in one, greatly improves the mounting strength and safety properties of composite panels. Taian one plate stone plate _ _ one off decorative stone from Shandong takeoff Decoration Engineering Co. The company provides Shandong takeoff Decoration Engineering Company Limited (#) strong, credible, in Tai'an, Shandong granite industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead off decorative and you work into the brilliant, for a better future!
