彩色钢板是连续单元冷轧钢带等一系列处理后生产的板材，制造商在设计板材时根据用户的使用需求制作了多种颜色下来，下年
济南彩钢厂家来带您理解彩色钢板涂层颜色的选择。
The color steel plate is produced after a series of treatments such as continuous unit cold-rolled steel strip. When designing the plate, the manufacturer has made a variety of colors according to the user's needs. Next year, Jinan color steel manufacturer will bring you to understand the color selection of the color steel plate coating.
彩色钢板涂层颜色的选择:颜色的选择主要考虑业主的喜好和周围环境的匹配程度，但从使用技术角度来看，浅色涂层的选择空间相对较大，可以选择一些耐久性更好的无机颜料。此外，该涂料具有较强的热反射能力，夏季涂层本身的温度相对较低，这有助于涂层的使用寿命。
Color selection of color steel plate coating: the color selection mainly considers the owner's preference and the matching degree of the surrounding environment. However, from the perspective of use technology, the selection space of light color coating is relatively large, and some inorganic pigments with better durability can be selected. In addition, the coating has strong heat reflection ability, and the temperature of the coating itself is relatively low in summer, which is helpful to the service life of the coating.
即使彩色钢板涂层变色或粉化，浅色涂层变化后与原色对比小，对外观影响不大。深色多采用有机颜色。如果紫外线照射容易褪色，短3个月就会变色。对于彩色涂层钢板，涂层和钢板的加热膨胀率通常不同，尤其是金属基板和有机涂层的线膨胀系数差异很大。当环境温度变化时，基板和涂层结合界面会膨胀或收缩，如果不能适当释放，涂层会开裂。
Even if the color steel plate coating is discolored or powdered, the contrast between the light color coating and the original color is small after the change, and the effect on the appearance is not great. Dark colors are mostly organic colors. If it is easy to fade under ultraviolet irradiation, it will change color within 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 very different. When the ambient temperature changes, the bonding interface between the substrate and the coating will expand or contract. If it cannot be released properly, the coating will crack.
此外，我们还需要解释国内市场的两个选择误区:
In addition, we also need to explain two wrong choices in the domestic market:
目前国内有大量的白色底漆。使用白色底漆的目的主要是减少面漆的厚度，因为正常建筑的防腐底漆是黄绿色的，所以需要足够的面漆厚度。
At present, there are a large number of white primers in China. The purpose of using white primer is mainly to reduce the thickness of the top coat. Since the anticorrosive primer of normal buildings is yellow green, sufficient thickness of the top coat is required.
建筑工程用彩色涂装钢板同一工程采用不同厂家、不同批次的彩色涂装钢板，施工中颜色似乎一致，但经过几年的阳光照射，不同涂层厂家的颜色变化趋势不同，色差会变得严重。
Color coated steel plates for construction projects the same project uses color coated steel plates of different manufacturers and batches. The color seems to be the same during construction. However, after several years of sunshine, the color change trend of different coating manufacturers is different, and the color difference will become serious.
