Wall insulation composite panels: wall insulation composite panels painted steel coil line is after the molding on both sides with a strong adhesive composite core material thicker, forming a high strength, light weight, thermal insulation rugged appearance of new building materials. Wall insulation composite panels are widely used in the top and wall light steel building products with bright color, no secondary decorative features, external wall insulation composite panels on a certain line is continuous conveyor line cargo handling machinery, also known as transfer line or conveyor. The transport products can be divided into: belt line, chain-line, multiple chain line, plug wire, wire mesh belt, suspension lines and drum lines seven categories pipeline. 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 coating, flatness ± 1cm, require two to three times to complete the insulation sprayed one plate, spraying each no more than 3cm thick, Master roof foam density greater than 40kg / m3, obturator rate is greater than 90% of the whole board, plus or minus the difference between the surface 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) 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 and other one board insulation quality, clear 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 facades one plate, off decorative ( Certified), one of the board by the Shandong takeoff Decoration Engineering Co., Ltd. Shandong takeoff Decoration Engineering Company Limited (#), quality of service and products, and are subject to approval and trust of new and old customers and the industry.
