Color steel sandwich panels have the characteristics of insulation, insulation, waterproofing, sound insulation, lightweight, and seismic resistance. Color steel sandwich panels are a multifunctional new type of building panel. Widely used for non load-bearing walls in industrial and civil buildings. Suitable for mechanical, chemical, pharmaceutical, electronic, biological, suspended food, etc. What are its characteristics? Below, Jinan Color Steel Sandwich Panel Factory will analyze for you:
Color steel sandwich panel is a kind of building panel, which is composed of two layers of color coated steel plates as the panel, and thermal insulation materials such as polystyrene, polyurethane, phenolic foam, rock wool, etc. as the core material. On a special automatic production line, the core material and the panel are combined into a whole through a continuous molding process, commonly known as "sandwich panel".
Although this composite board has been introduced to China for less than 20 years, it has been widely recognized and used in clean rooms due to its advantages such as load-bearing, insulation, decoration, waterproofing, and simple construction. It poses a challenge to traditional building materials such as bricks and stones, and has become a new force in the building materials industry.
1. When we look at the color steel sandwich panel, the first thing to pay attention to is the outer leakage edge. Usually, high-quality color steel sandwich panels have very fine crystals at the edges, and there are no impurities such as blackening or graying.
2. Gently tap the surface of the color steel sandwich panel with our fingers and listen to the sound to determine the quality. If the quality of sandwich panels is relatively poor, the sound produced is very dull, while high-quality sandwich panels can produce a crisp sound.
3. The base film and coating of color steel sandwich panels also need to be paid attention to. The base film thickness of high-quality color steel sandwich panels is usually maintained between 0.02 and 0.05mm, while the coating is controlled below 0.15mm.
To ensure that there are no leakage issues with the insulation material, the surface needs to be dry, free of grease, and corrosion. Only after these conditions are met can appropriate coatings be applied. Materials are used for outdoor insulation or places susceptible to mechanical wear and tear. Pay attention to the sealing of the joints. If necessary, seal tightly with glue, and the overlapping part shall not be less than 100mm. If used for cold insulation, a moisture-proof layer must be added. When the outdoor temperature is very low, rock wool should be used for insulation to slowly increase the temperature.
To avoid further losses caused by excessive heat, please note that the connection between the board and the felt must be very tight. When using multi-layer insulation, all connecting parts should be staggered to avoid the formation of thermal bridges. When the temperature is too high, exceeding 200 ℃, an outer layer of protection needs to be added, so that expansion will not cause deformation of the color steel sandwich panel.
