Nowadays, the most commonly used construction material is thermal insulation material, and the external wall insulation decoration integrated board is a new type of material. Its insulation and decoration effect is very popular among consumers. Many people are not faced with the choice of insulation materials. Know how to choose. Today, Xiaobian will take a look at the exterior wall insulation decoration integrated board purchase skills and the external wall insulation decoration integrated board purchase considerations! Exterior wall insulation decoration integrated board purchase skills 1. Look at the material; the material needs some identification, and whether it will affect the use effect. The more important thing is the quality problem. Sometimes the appearance does not see the quality, so further testing is needed. 2. Look at the manufacturer; the manufacturer's production, this is a brand effect, not all manufacturers have a brand effect. In every field, there are some well-known manufacturers that produce some materials that are much better than the quality. It is more convenient to solve some problems in the later period, which is a key point. 3. Look at the price; the price is a certain difference, even if the product produced by the same company, there will be a certain difference in the price of the later sale. 4. Before buying, carefully check the appearance of the exterior wall insulation and decoration board. Choose those that have less damage, uniform color, and uniform size. 5. Calculate the density of the product during the purchase process. Select a small sample to weigh and then measure the volume to calculate its density. In general, the lower the density, the better the product. Detect the strength of the product. The strength requirements of the external wall insulation and decoration integrated board, insulation decorative board, etc. are to meet the needs of handling during construction, and there is no phenomenon of breakage. What are the construction precautions for the board? 1. On-site pouring of polyurethane insulation. After the wall of the building is dried, the polyurethane can be sprayed directly on the surface. Generally, the thickness of the coating is about 4 cm, and a high-pressure sprayer is required to make the surface as flat as possible. The polymer cement is scraped on the finished foam and then externally decorated. 2. Prefabricated insulation sandwich panels. Generally, polyurethane sandwich panels processed on a continuous production line are used, and the outer surface is often made of colored steel or aluminum, and the back is mostly made of aluminum foil. When installing, first make the keel on the outer wall, then fix the plate on the keel, or use the double-sided color steel plate as the wall material, which is both beautiful and has good thermal insulation effect. External wall insulation decoration integrated board purchase considerations First, the fire rating. In the past two years, building fires have been frequent, and wall insulation materials have become the focus of attention. While the insulation material emphasizes energy-saving insulation, it is bound to determine the development direction of insulation materials. Improve the fire performance of insulation materials, the state gives policy care, domestic A-class insulation materials will certainly develop rapidly. Second, waterproof performance. The water absorption rate of the material is an important factor that should be considered when selecting a thermal insulation material. The thermal conductivity of water at room temperature is twenty-three times that of air. When the insulating material absorbs water, it not only greatly reduces its thermal insulation performance, but also accelerates the corrosion of the metal, which is very harmful. The void structure of the thermal insulation material is divided into a connected type, a closed type, and a semi-closed type. Except for a small number of voids of the organic foam plastic, most of the voids are closed type, and the other heat insulating materials absorb water regardless of the void structure, and the joint gap is added. The capillary is permeable to water, so the overall water absorption rate is high. At present, most of the thermal insulation materials in China are not water-repellent and have a high water absorption rate. As a result, the waterproof requirements of the outer sheath are very strict, and the cost of the outer sheath is increased. We need to have a certain understanding of the insulation board before purchasing the insulation material and then go shopping. The above is the introduction of the exterior wall insulation decoration integrated board for the introduction of the outer wall insulation decoration board and the purchase of the outer wall insulation decoration board. The end is here. For more information, please continue to pay attention to the decoration. Family.
