1、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, check: check whether the workpiece prior to pickling process with iron hole factory galvanized (zinc and exhaust, night, hanging), the corrosion degree of surface iron workpiece, the surface cover can be removed (such as hydrochloric acid paint, grease should be used in fire, grinding, cleaning 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 galvanizing zinc liquid: workpiece immersed in 440 -470 DEG C molten, reached after a certain time, the surface of workpiece is obtained with a layer of zinc iron alloy layer and pure zinc coating layer.

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
