鍍鋁鋅板在實際使用過程中所具備的特點非常明顯，因為它經過處理之后確實具備很好的防腐蝕性能，在惡劣環境或者正常的環境中都可以放心使用。鍍鋁鋅板分為鈍化、涂油、鈍化涂油、漆封、磷化或不處理等類別。下面就簡單為大家介紹一下鍍鋁鋅板的表面處理工藝分類有哪些？

The characteristics of aluminum zinc plated sheet in practical use are very obvious, because it does have good anti-corrosion performance after treatment, and can be used with confidence in harsh or normal environments. Aluminum zinc plated plates are classified into passivation, oiling, passivation oiling, paint sealing, phosphating or untreated categories. What are the classifications of surface treatment processes for aluminum zinc plated sheets?

鍍鋁鋅板的表面處理工藝分類：

Classification of surface treatment processes for aluminum zinc plated sheets:

（1）鈍化鍍鋁鋅板。鈍化的鍍鋁鋅板是為了減少在潮濕條件下產生白銹，在鍍鋅以后的產品表面進一步涂敷一層鈍化保護膜。按鈍化膜的種類又分為六價鉻鈍化、三階鉻鈍化、無鉻鈍化等產品，一般不用于鋅鐵合金板。

(1) Passivation of aluminum zinc plate. Passivation of aluminum zinc plate is to reduce the formation of white rust under humid conditions, and a passivation protective film is further applied to the surface of the galvanized product. According to the type of passivation film, it can be divided into hexavalent chromium passivation, third-order chromium passivation, chromium free passivation and other products, which are generally not used for zinc iron alloy plates.

（2）涂油鍍鋁鋅板。鍍鋁鋅板涂油的目的同樣是為了防止產品受潮而產生白銹，但由于防銹油非常容易揮發或被擦除，所以只能在使用之前發揮作用。涂油的方法有靜電涂油和輥涂油等，如果要防止鍍鋁鋅板在使用期內產生白銹，建議采用鈍化加涂油的辦法。彩涂基板比較適宜輕涂油處理，所涂的油能在彩涂線前處理中被清洗去除。

(2) Oil coated aluminum zinc plate. The purpose of coating aluminum zinc plate with oil is also to prevent the product from getting damp and producing white rust, but due to the easy volatilization or erasure of rust proof oil, it can only be effective before use. The methods of oiling include electrostatic oiling and roller oiling. To prevent white rust from forming on aluminum zinc coated plates during their service life, it is recommended to use passivation and oiling. Color coated substrates are more suitable for light oil treatment, and the applied oil can be cleaned and removed during the pre-treatment of the color coating line.

（3）漆封鍍鋁鋅板。漆封俗稱耐指紋產品，為了防止鍍鋁鋅板在加工過程中留下指紋，在鍍鋅后的產品表面再涂覆一層非常薄的耐指紋保護膜。同時也能提高鍍鋁鋅板的耐腐蝕性能和產品的涂裝性能。

(3) Paint sealed aluminum zinc plate. Lacquer sealed products, commonly known as fingerprint resistant products, are coated with a particularly thin layer of fingerprint resistant protective film on the surface of the galvanized product to prevent fingerprints from being left during the processing of aluminum zinc coated plates. At the same time, it can also improve the corrosion resistance of aluminum zinc coated plates and the coating performance of products.

（4）磷化鍍鋁鋅板。鍍鋁鋅板是為防止鋼板表面遭受腐蝕，延長其使用壽命。在鋼板表面涂以一層金屬鋅，這種涂鋅的薄鋼板稱為鍍鋁鋅板。鍍鋅是一種經常采用的經濟而更好的防腐方法，全世界鋅產量的一半左右均用于此工藝。

(4) Phosphated aluminum zinc plate. Aluminum zinc plated plate is used to prevent corrosion on the surface of steel plates and extend their service life. A thin steel plate coated with a layer of metallic zinc on its surface is called aluminum zinc coated plate. Galvanizing is a commonly used economical and better anti-corrosion method, with about half of the world's zinc production used in this process.
