客 户可以按照自己的需求去选择彩钢板的颜色，如何能正确的选择到心目中理想的彩钢板。1、彩钢板颜色的美观效果，有的用户会根据自己喜欢的颜色来买；2、彩钢板的颜色和使用寿命也是有一定的关系。 涂层耐久性是彩钢板在使用过程中体现出来的性能，通常用美观寿命和大修寿命的长短进行衡量： 美观寿命：从彩钢板制造完成之日至其表面涂层发生一定程度的失色和粉化等影响涂层原有美观效果的时间间隔。 使用寿命：钢板锈蚀穿孔，无法使用。彩钢板腐蚀失效的过程：涂层失光——涂层变色——涂层粉化——涂层开裂—— 涂层起泡——白锈/红锈——涂层脱落——镀层大面积白锈——钢板锈蚀穿孔——钢板失效。根据实验结果： 正面涂层≥20微米才能有效的防止腐蚀介质侵入，由于底漆和面漆的防腐蚀机理不同， 所以要分别要求底漆（≥5微米）和面漆（≥15微米）的厚度，只有这样，才能保证彩钢板不同部位的耐蚀性是均衡的。 Customers can choose the color of the color steel plate according to their own needs, how to correctly choose the ideal color steel plate in the mind.1. The beautiful effect of color steel plate color, some users will buy according to their favorite color;2, the color of color steel plate and service life is also have a certain relationship.Coating durability is the performance of color steel plate in the process of use, which is usually measured by the length of beautiful life and overhaul life:aesthetic life: the time interval from the completion date of the manufacture of color steel plate to the certain degree of color loss and powder of the surface coating that affect the original aesthetic effect of the coating.Service life: the steel plate is rust-perforated and cannot be used.Process of color steel plate corrosion failure: coating loss —— coating —— color ——coating powder —— coating cracking —— coating foam —— white rust / red rust —— coating loss —— coating large area white rust—— steel plate rust perforated —— steel plate failure.According to the experimental results: the front coating of 20 microns can effectively prevent the invasion of corrosion medium. Because the corrosion prevention mechanism of primer and primer is different,the thickness of primer (5 micron) and primer (15 micron) should be required respectively. Only in this way,the corrosion resistance of different parts of the color steel plate can be balanced.
