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 spraying completed Buying one thin stone plate, spraying each no more than 3cm thick, Master roof foam density greater than 40kg / m3, closed porosity of 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) 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 pollution prevention work to do around the whole thin stone slab quality, 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 why one board for an exterior wall decoration both insulation and fire protection? grouts often used on the building's exterior decoration decorative one external wall insulation board used (silicone weather sealant) efflorescence will affect the external decorative effect, greatly reducing the building exterior finishes thin stone one plate appearance, life span of use. to house wear "coat", not only cool one thin stone plate, but also save energy, but the outcome, but also the "coat" quality. Yesterday, by Construction of the new standard in 2013 the national external wall insulation system Dalian Municipal Energy Association's new specification development seminars be held in Dalian, focuses on how to produce both thermal insulation and fireproof "coat" - one exterior wall decoration board, according to reports, current domestic and external insulation materials can be divided into two kinds of inorganic materials with organic material domestic organic materials are mostly decorative wall insulation polystyrene board one board, insulation is good, but the fire is poor; whereas most domestic inorganic materials using expanded perlite and foam concrete, no fire hazards, but somewhat less insulation. At present, the country also began producing high-quality glass wool, rock wool, mineral wool and other inorganic materials, both fireproof insulation is also good, but due to the higher cost will not be widely accepted by the market thin stone one board price |. thin stone one board | takeoff takeoff decoration Decoration Engineering Co. Ltd. from Shandong, Shandong takeoff Decoration Engineering Co., Ltd. to provide (#) strong, credible, in. Taian granite industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead off into the brilliant decor and you work for a better future!
