、酸洗前检查处理:检查铁艺工件是否具备本厂镀锌的工艺孔(排气、出入锌夜、吊挂),铁艺工件表面的锈蚀程度,表面覆盖物能否被盐酸除去(如有油漆、油脂等应采用火烧、打磨、碱洗等法除去)。

1, pickling examination before treatment: iron workpiece is examined whether they have the galvanizing plant process hole (exhaust, access to the night in zinc, hanging), wrought iron workpiece surface corrosion degree, the surface coverings can by hydrochloric acid to remove (such as paint, grease should be by burning, grinding, alkali washing method to remove).

2、脱脂(碱洗):配有加热设备,消除铁艺工件表面的油脂、涂料等。

2, skim (Jian Xi): equipped with heating equipment, remove surface grease, paint and other iron workpiece。

3、水洗:清除铁艺工件表面的碱水及附着物。

3, wash: remove salt and iron workpiece surface attachment.

4、酸洗:除去铁锈、氧化皮等其它表面覆盖物

4, pickling: remove rust, oxide skin and other surface coverings

5、酸洗后检查处理:酸洗效果是否理想,如酸洗不充分,再次酸洗,如果酸洗前处理不彻底,需重新处理后再次酸洗。

5, after pickling check processing: pickling effect is ideal, such as pickling is not sufficient, once again, if the pickling before treatment is not thorough, need to re - processing after pickling。

6、水洗:除去铁艺工件表面的酸水及其它附着物

6, washing: remove the surface of the iron acid water and other attachments

7、上助镀剂:再次清洗工件表面,保证表面在镀锌之前不在生锈。

7, the plating agent: once again cleaning the workpiece surface, to ensure that the surface is not in the rust before galvanized。

8、烘干:提高铁艺工件温度,避免铁艺表面水分过多,在镀锌时发生爆炸。

8, drying: improve iron workpiece temperature, avoid excessive iron surface water, the explosion occurred in galvanizing。

9、热浸锌:工件浸泡于440℃-470℃熔融的锌液中,达到一定时间后提出,铁艺工件表面被获得一层锌铁合金层和纯锌层镀层。

9, hot dip galvanized: workpieces are soaked in 440 DEG C - 470 DEG C molten zinc liquid to a certain period of time after the and iron on the surface of the workpiece is obtained a Zn Fe alloy layer and pure zinc coatings.

10、钝化:提供工件表面抗大气的腐蚀性能,减少或延长白锈出现的时间。

10, passivation: to provide the workpiece surface resistance to atmospheric corrosion, reduce or prolong the time of white rust。

11、冷却:防止工件激冷回缩,产生集体组织开裂。

11, cooling: to prevent the cooling of the workpiece back to shrink, resulting in collective tissue cracking。

12、精整:清除锌瘤及附着在镀层表面的锌灰

12, finishing: clear zinc tumor and attached to the surface coating of zinc ash

13、检验:镀层的检验和测定,工件的外观检查。

13, inspection: the inspection and testing of the coating, the appearance of the workpiece inspection。
