用電鍍鋅板為基板，涂上有機(jī)涂料烘烤所得的產(chǎn)品為電鍍鋅彩涂板，由于電鍍鋅板的鋅層薄，通常含鋅量為20/20g/m2，因此該產(chǎn)品不適合使用在室外制作墻、屋頂?shù)取５蚓哂忻利惖耐庥^和優(yōu)良的加工性能，因此主要可用于家電、音響、鋼家 具、室內(nèi)裝璜等。從防腐機(jī)理的角度看，鋅、鋁在多數(shù)大氣環(huán)境下具有較高的穩(wěn)定性，利用它作為鋼鐵基體的防護(hù)性涂(鍍)層是普遍公認(rèn)的有效經(jīng)濟(jì)的方法，其應(yīng)用歷史已達(dá)一百多年。鋅在腐蝕環(huán)境介質(zhì)中會形成一層薄且致密的附著性很強(qiáng)的腐蝕產(chǎn)物(氧化鋅，氫氧化鋅，堿性鹽：Zn(OH)2和ZnCl2或ZnCO3)。這些產(chǎn)物覆蓋在其表面對周圍環(huán)境介質(zhì)起著屏蔽作用，從而阻止進(jìn)一步腐蝕。

Electric galvanized board is the substrate, and the product obtained by baking with organic coating is electrogalvanized color coated board. Because the zinc layer of galvanized board is thin, the zinc content is usually 20 / 20g / m2, so this product is not suitable for use in outdoor production walls, roof, etc. But because of the beautiful appearance and excellent processing performance, so mainly can be used for home appliances, audio, steel furniture, indoor decoration, etc. From the perspective of anti-corrosion mechanism, zinc and aluminum have high stability in most atmospheric environments. It is generally recognized as the protective coating (plating) layer of iron and steel matrix, and its application history has reached more than one hundred years. Zinc in a corrosive environmental medium forms a thin and dense layer of highly attached corrosion products (zinc oxide, zinc hydroxide, alkaline salt: Zn (OH) 2 and ZnCl2 or ZnCO3). These products cover their surfaces with a shielding effect against the surrounding ambient media, thus preventing further corrosion.

此外，鋅的電極電位較鐵為負(fù)，屬于陽極性鍍層，它具有犧牲自身的保護(hù)作用。鍍鋅層在大氣環(huán)境中的腐蝕盡管隨氣候類型的變化發(fā)生很大變化(一般在海洋性氣候中很嚴(yán)重)，然而在相同的環(huán)境條件下，其壽命正比于鍍鋅層的附著量。美國ASTM發(fā)表在《金屬手冊》中

的結(jié)果可見欲延長其壽命，可用增加鍍鋅層厚度的方法來實(shí)現(xiàn)。

In addition, the electrode potential of zinc is more negative than iron, which belongs to the anodic coating, which has the protective effect of sacrificing itself. Although the corrosion of galvanized layer in the atmospheric environment changes greatly with the climate type (generally severe in the Marine climate), its life is proportional to the amount of galvanized layer attachment under the same environmental conditions. ASTM is published in the Metal Manual The results can be seen to extend its life, can be used to increase the thickness of the galvanized layer to achieve.
