彩色鋼板是連續(xù)單元冷軋鋼帶等一系列處理后生產的板材，制造商在設計板材時根據(jù)用戶的使用需求制作了多種顏色下來，下年
濟南彩鋼廠家來帶您理解彩色鋼板涂層顏色的選擇。
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.
彩色鋼板涂層顏色的選擇:顏色的選擇主要考慮業(yè)主的喜好和周圍環(huán)境的匹配程度，但從使用技術角度來看，淺色涂層的選擇空間相對較大，可以選擇一些耐久性更好的無機顏料。此外，該涂料具有較強的熱反射能力，夏季涂層本身的溫度相對較低，這有助于涂層的使用壽命。
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.
即使彩色鋼板涂層變色或粉化，淺色涂層變化后與原色對比小，對外觀影響不大。深色多采用有機顏色。如果紫外線照射容易褪色，短3個月就會變色。對于彩色涂層鋼板，涂層和鋼板的加熱膨脹率通常不同，尤其是金屬基板和有機涂層的線膨脹系數(shù)差異很大。當環(huán)境溫度變化時，基板和涂層結合界面會膨脹或收縮，如果不能適當釋放，涂層會開裂。
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，我們還需要解釋國內市場的兩個選擇誤區(qū):
In addition, we also need to explain two wrong choices in the domestic market:
目前國內有大量的白色底漆。使用白色底漆的目的主要是減少面漆的厚度，因為正常建筑的防腐底漆是黃綠色的，所以需要足夠的面漆厚度。
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.
建筑工程用彩色涂裝鋼板同一工程采用不同廠家、不同批次的彩色涂裝鋼板，施工中顏色似乎一致，但經過幾年的陽光照射，不同涂層廠家的顏色變化趨勢不同，色差會變得嚴重。
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.
