One board insulation building insulation _ _ off one plate decorated by the Shandong takeoff Decoration Engineering Limited. Shandong takeoff Decoration Engineering Company Limited (#) is Taian, granite leaders, over the years, the company is implementing scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the off decorative leadership with the staff warmly welcome all inquiries negotiations to create a better future for takeoff decoration. Green ring exterior wall decoration panel system features: Features one: thermal insulation properties: decorative wall insulation board can play a cool effect, which can meet the requirements of building energy efficiency in different regions. Features 2: energy saving and strong: the status quo of non-renewable resource generation for heating, played a lot of festival source effect. Features three: beautiful decorative excellent: surface using a self-developed a new generation of green ring decorative coatings, color-rich whole building insulation board, texture multiforme, impact resistance, and does not crack. Features four: easy maintenance: wall insulation decorative plates simple, safe, reliable, greatly reducing installation period, little affected by environmental factors. Features five: Use a wide range: applies to all "new construction" or "existing buildings." 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 insulation sprayed one board manufacturers, the flatness of ± 1cm one colored insulation boards, require two to three times spraying is completed, spray each one no more than 3cm thick insulation board, Master roof foam density is 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 trimmed polyurethane insulation thickness
