小家電彩板一般以電鍍鋅和冷板為基板，用于生產(chǎn)冰箱和大型空調(diào)系統(tǒng)，冰柜、面包機(jī)、家具等。交通運(yùn)輸業(yè)上一般以電鍍鋅和冷板為基板，主要用于油底殼，汽車內(nèi)飾件等。

Small home appliance color plate is generally electrogalvanized and cold plate as the substrate, used for the production of refrigerator and large air conditioning system, freezer, bread machine, furniture and so on.Transportation industry is generally with electrogalvanized and cold plate as the substrate, mainly used for oil pan, automotive interior parts, etc.

使用電鍍鋅板為基板，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)?。但因具有美麗的外觀和優(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(huì)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(duì)周圍環(huán)境介質(zhì)起著屏蔽作用，從而阻止進(jìn)一步腐蝕。此外，鋅的電極電位較鐵為負(fù)，屬于陽(yáng)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(guó)ASTM發(fā)表在《金屬手冊(cè)》中的結(jié)果可見欲延長(zhǎng)其壽命，可用增加鍍鋅層厚度的方法來(lái)實(shí)現(xiàn)。

Using galvanized plate as the substrate, coated with organic paint baking products for galvanized color coating plate, because the zinc layer of galvanized plate, usually contain zinc content of 20 / 20g / m2, so the 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 in home appliances, audio, steel furniture, indoor decoration, etc.From the perspective of anti-corrosion mechanism, zinc and aluminum have high stability in most atmospheric environment, using it as a protective coating (coating) of steel matrix layer is generally recognized as an effective and economic method, its application history has reached more than one hundred years.Zinc in the corrosive environment medium will form a thin and dense attachment of strong corrosion products (zinc oxide, zinc hydroxide, alkaline salt: Zn (OH) 2 and ZnCl2 or ZnCO3).These products cover their surfaces to shield the ambient medium, thus preventing further corrosion.In addition, the electrode potential of zinc is negative than iron, which belongs to the anodic coating, which has the protective effect of sacrificing itself.The corrosion of galvanized layer in atmospheric environment changes greatly with climate type (generally severe in Marine climate), but its life is proportional to the attachment of galvanized layer under the same environmental conditions.The results of ASTM published in the Metal Manual show that its life can be extended by increasing the thickness of the galvanized layer.
