With the development of recent years, more and more people begin to pay attention to the development trend of color steel plate. What is the selection of coating color for color steel plate? Let's follow Xiaobian to have a look:
Color selection of color steel plate coating: the selection of color is mainly considering the matching with the surrounding environment and the owner's hobby. However, from the perspective of application technology, there is a wide range of pigment selection for light color coatings. Inorganic pigments (such as titanium dioxide) with superior durability can be selected. Moreover, the thermal reflection ability of the coating is strong (the reflection coefficient is twice of that of the dark color coating). The temperature of the coating itself is relatively high in summer This is beneficial to the prolongation of coating life.
Even if the coating is discolored or powdered, the contrast between the light color film and the original color is small, and the effect on the appearance is not obvious. Dark colors (especially bright colors) are mostly organic colors, which fade easily when exposed to ultraviolet radiation, and change color in a short period of 3 months. For color coated steel plate, the thermal expansion rate of coating and steel plate is usually different, especially the linear expansion coefficient of metal substrate and organic coating is quite different. When the ambient temperature changes, expansion or contraction stress will occur at the interface between the substrate and the coating, and if it can not be properly released, the coating cracking will occur.
