铝锌合金和锌铝镁合金等耐腐蚀效果更好的合金元素加入到了钢板表面（金属镀层），不仅提升了钢板的寿命，延长了建筑的使用年限，那么非金属涂层对钢板的寿命有哪些影响呢？下面济南彩钢板厂为您讲解：

Aluminum zinc alloy, zinc aluminum magnesium alloy and other alloy elements with better corrosion resistance are added to the steel plate surface (metal coating), which not only improves the service life of the steel plate, but also extends the service life of the building. What effect does the non-metallic coating have on the service life of the steel plate? Jinan Color Steel Plate Factory will explain to you:

涂镀钢板失效影响因素

Influencing factors of failure of coated steel plate

用于建筑用途的彩涂板主要受到太阳光中的紫外线、空气中水分和工业污染带来的有害物质的影响降低使用寿命。建筑用彩涂产品的防腐蚀是镀层、预处理膜和涂层（底漆、面漆和背面漆）的组合作用。这种组合十分重要，直接影响其使用寿命。

Color-coated panels used for building purposes are mainly affected by ultraviolet rays in the sun, moisture in the air and harmful substances caused by industrial pollution, and their service life is reduced. Anti-corrosion of architectural color coating products is the combination of coating, pretreatment film and coating (primer, finish and back paint). This combination is very important and directly affects its service life.

TIPS：当Zn、Al、Mg三元共晶相（锌铝镁）在整个镀层组织中的含量达到一定程度后，腐蚀产物不溶性胶状物质，电导率较低，能有效隔断镀层与外界物质传输，从而在钢板表面形成一层致密的、有效防止腐蚀的保护层，阴极反应会随着这种双层结构的出现得到有效抑制，使镀层的耐蚀性得到显著提高。

TIPS: When the content of Zn, Al and Mg ternary eutectic phases (zinc aluminum magnesium) in the whole coating structure reaches a certain level, the corrosion products are insoluble colloidal substances with low conductivity, which can effectively cut off the transmission of coating and external substances, thus forming a dense and effective corrosion protection layer on the surface of the steel plate. The cathodic reaction will be effectively suppressed with the appearance of this double-layer structure, and the corrosion resistance of the coating will be significantly improved.

涂层失效、镀层失效乃至钢板穿孔是关键的腐蚀发生过程。因此提高涂镀层厚度，且采用耐候、耐蚀涂镀层是有效的防止彩涂板腐蚀失效的手段。

Coating failure, coating failure and even steel plate perforation are the key corrosion processes. Therefore, improving the coating thickness and adopting weather-resistant and corrosion-resistant coating are effective means to prevent corrosion failure of color coated plates.

涂镀层是为了保证建筑物的耐久性、耐蚀性而考虑的，不同的用途可以通过选择不同的镀层、涂层和厚度以满足其使用寿命。现在常用的卷钢涂料的面漆品种有聚酯（PE）、硅改性聚酯（SMP）、高耐久聚酯（HDP），氟碳（PVDF）；底漆和背面的漆的品种有环氧（EP）、聚酯（PE）、聚氨酯（PU）等。

Coating is considered to ensure the durability and corrosion resistance of buildings. Different coatings, coatings and thicknesses can be selected for different purposes to meet their service life. At present, the commonly used types of coil steel coatings are polyester (PE), silicon modified polyester (SMP), high durability polyester (HDP) and fluorocarbon (PVDF); The varieties of primer and back paint include epoxy (EP), polyester (PE), polyurethane (PU), etc.
