Color steel sandwich panels not only have the properties of high mechanical strength and easy forming of steel materials, but also have the good decorative and corrosion resistance of coating materials. Color steel sandwich panel is a new material highly praised in the world today. With the progress of science and technology, the enhancement of environmental awareness, and the improvement of people's living standards, color steel sandwich panel movable houses are showing more and more strong vitality and broad market prospects, and are favored by architecture, home appliances, electromechanical, transportation, interior decoration, office appliances and other industries.
The cores used in color steel sandwich panels mainly include phenolic foam, polystyrene, extruded polystyrene, rigid polyurethane, terpolyester and rock wool. Phenolic foam has excellent fire and thermal insulation performance, which can not be replaced by other materials. For example, the thermal insulation effect of phenolic foam is more than twice that of polystyrene, and its fire performance is also higher than that of polyurethane. When polyurethane burns, it will release dense smoke containing hydrogen cyanide.
With the national attention to building fire prevention and the introduction of relevant laws, it is believed that phenolic color steel sandwich panels will create a blue sky in the building field.
