鐵藝護欄熱浸鍍鋅的工藝特點

來源:http://www.macyplace82.com添加時間:2021-10-05 16:54:07

酸洗前檢查處理:檢查鐵藝工件是否具備本廠鍍鋅的工藝孔(排氣、出入鋅夜、吊掛),鐵藝工件表面的銹蝕程度,表面覆蓋物能否被鹽酸除去(如有油漆、油脂等應采用火燒、打磨、堿洗等法除去)。

Inspection and treatment before pickling: check whether the iron work piece has the galvanized process hole of the factory (exhaust, zinc in and out, hanging), the degree of corrosion on the surface of the iron work piece, and whether the surface cover can be removed by hydrochloric acid (if there is paint, grease, etc., it shall be removed by fire, grinding, alkali washing, etc.).

脫脂(堿洗):配有加熱設備,消除鐵藝工件表面的油脂、涂料等。

Degreasing (alkaline washing): equipped with heating equipment to eliminate grease, coating, etc. on the surface of iron workpieces.

水洗:清除鐵藝工件表面的堿水及附著物。

Water washing: remove alkaline water and attachments on the surface of iron work pieces.

酸洗:除去鐵銹、氧化皮等其它表面覆蓋物

Pickling: remove rust, scale and other surface coverings

酸洗后檢查處理:酸洗效果是否理想,如酸洗不充分,再次酸洗,如果酸洗前處理不徹底,需重新處理后再次酸洗。

Inspection and treatment after pickling: whether the pickling effect is ideal. If the pickling is not sufficient, pickling shall be carried out again. If the treatment before pickling is not complete, pickling shall be carried out again after re treatment.

上助鍍劑:再次清洗工件表面,保證表面在鍍鋅之前不在生銹。

Apply plating aid: clean the workpiece surface again to ensure that the surface is not rusted before galvanizing.

烘干:提高鐵藝工件溫度,避免鐵藝表面水分過多,在鍍鋅時發生爆炸。

Drying: raise the temperature of wrought iron workpiece to avoid excessive moisture on the surface of wrought iron and explosion during galvanizing.

熱浸鋅:工件浸泡于440℃-470℃熔融的鋅液中,達到一定時間后提出,鐵藝工件表面被獲得一層鋅鐵合金層和純鋅層鍍層。

Hot dip galvanizing: the workpiece is immersed in molten zinc at 440 ℃ - 470 ℃ and put forward after a certain time. A layer of zinc iron alloy layer and pure zinc layer are obtained on the surface of iron workpiece.

鈍化:提供工件表面抗大氣的腐蝕性能,減少或延長白銹出現的時間。

Passivation: provide atmospheric corrosion resistance of workpiece surface, reduce or prolong the time of white rust.

冷卻:防止工件激冷回縮,產生集體組織開裂。

Cooling: prevent the workpiece from chilling and retracting, resulting in collective tissue cracking.

精整:清除鋅瘤及附著在鍍層表面的鋅灰

Finishing: remove zinc nodules and zinc dust attached to the coating surface

檢驗:鍍層的檢驗和測定,工件的外觀檢查。

Inspection: Inspection and measurement of coating and appearance inspection of workpiece.
