電鍍鋅：行業(yè)內又稱冷鍍鋅，就是利用電解，在制件表面形成均勻、致密、結合良好的金屬或合金沉積層的過程。

Electrogalvanizing: also known as cold galvanizing in the industry, is the use of electrolysis, in the surface of the parts to form uniform, dense, well combined metal or alloy deposition process.

與其他金屬相比，鋅是相對便宜而又易鍍覆的一種金屬，屬低值防蝕電鍍層，被廣泛用于保護鋼鐵件，特別是防止大氣腐蝕，并用于裝飾。

Compared with other metals, zinc is a relatively cheap and easy to coat a metal, a low value corrosion protection plating layer, is widely used to protect steel parts, especially against atmospheric corrosion, and used for decoration.

鍍覆技術包括槽鍍（或掛鍍）、滾鍍（適合小零件）、自動鍍和連續(xù)鍍（適合線材、帶材）。

Coating techniques include tank plating (or hanging plating), rolling plating (suitable for small parts), automatic plating and continuous plating (suitable for wire, strip).

電解板的工藝：國內按電鍍溶液分類，可分為四大類：

Electrolytic plate process: according to the domestic electroplating solution classification, can be divided into four categories:

1、氰化物鍍鋅：

由于(CN)屬劇毒，所以環(huán)境保護對電鍍鋅中使用氰化物提出了嚴格限制，不斷促進減少氰化物和取代氰化物電鍍鋅鍍液體系的發(fā)展，要求使用低氰(微氰)電鍍液。

1. Cincide galvanizing:

Because (CN) is highly toxic, environmental protection puts forward strict restrictions on the use of cyanide in galvanizing, and continuously promotes the development of electrogalvanized liquid system to reduce cyanide and replace cyanide, requiring the use of low cyanide (microcyanide) plating liquid.

采用此工藝電鍍后，產品質量好，特別是彩鍍，經鈍化后色彩保持好。

After plating with this process, the product quality is good, especially the color plating, and the color is good after passivation.

2、鋅酸鹽鍍鋅：

此工藝是由氰化物鍍鋅演化而來的。目前國內形成兩大派系，分別為： a)武漢材保所的”DPE”系列；b) 廣電所的”DE”系列 。都屬于堿性添加劑的鋅酸鹽鍍鋅；PH值為12.5~13。

2. Zinc acid salt galvanizing:

This process is evolved from cyanide galvanization. At present, two major factions have been formed in China, namely: a) "DPE" series of Wuhan Material Protection Institute; b) "DE" series of Wuhan Radio and Television Institute. Zinc additive; PH value is 12.5~13.

采用此工藝，鍍層晶格結構為柱狀，耐腐蝕性好，適合彩色鍍鋅。

Using this process, the plating lattice structure is columnar, with good corrosion resistance and suitable for color galvanization.

注意：產品出槽后→水洗→出光(硝酸+鹽酸)→水洗→鈍化→水洗→水洗→燙干→烘干→老化處理(烘箱內80~90℃)。 

Note: After washing out of the tank, wash light (nitric acid + hydrochloric acid), blunt washing, drying, drying and aging treatment (80~90℃ in the oven).

3、氯化物鍍鋅

此工藝在電鍍行業(yè)應用比較廣泛，所占比例高達40%。

鈍化后(藍白)可以鋅代鉻(與鍍鉻相媲美)，特別是在外加水溶性清漆后，外行人是很難辯認出是鍍鋅還是鍍鉻的。

此工藝適合于白色鈍化(藍白，銀白)。

3, Chloride is galvanized

This process is widely used in the electroplating industry, accounting for up to 40%.

After passivation (blue and white) can be zinc chromium (comparable to chrome), especially after the addition of water-soluble varnish, it is difficult for laymen to identify whether galvanized or chrome.

This process is suitable for white passivation (blue and white, silver and white).

4、硫酸鹽鍍鋅

此工藝適合于連續(xù)鍍(線材、帶材、簡單、粗大型零、部件)，成本低廉。

4, sulfate galvanizing

This process is suitable for continuous plating (wire, strip, simple, large parts, parts), low cost.
