酸洗前检查处理
Inspection and treatment before pickling
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)。
Check whether the iron work piece has the galvanized process hole of the factory (exhaust and zinc hanging at night), the degree of corrosion on the surface of the iron work piece, and whether the surface covering can be removed by hydrochloric acid (if there is paint grease, it shall be removed by fire grinding, alkali washing, etc.).
脱脂(碱洗)
Degreasing (alkali washing)
配有加热设备,消除铁艺工件表面的油脂涂料等。
Equipped with heating equipment to eliminate grease and coating on the surface of iron work pieces.
水洗
washing
清除铁艺工件表面的碱水及附着物。
Remove alkali water and attachments on the surface of wrought iron workpieces.
酸洗
pickling
除去铁锈氧化皮等其它表面覆盖物
Remove rust, scale and other surface coverings
酸洗后检查处理:
Inspection and treatment after pickling:
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。
Whether the pickling effect is ideal. If the pickling is insufficient, pickling shall be carried out again. If the treatment before pickling is not complete, pickling shall be carried out again after re treatment.

上助镀剂
Upper plating aid
再次清洗工件表面,保证表面在镀锌之前不在生锈。
Clean the workpiece surface again to ensure that the surface does not rust before galvanizing.
烘干
dry
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。
Raise the temperature of wrought iron workpiece to avoid excessive moisture on the surface of wrought iron and explosion during galvanizing.
热浸锌
Hot dip galvanizing
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。
After the workpiece is immersed in molten zinc at 440 ℃ - 470 ℃ for a certain time, a layer of zinc iron alloy layer and pure zinc layer are obtained on the surface of iron workpiece.
钝化
passivation
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。
Provide atmospheric corrosion resistance of workpiece surface to reduce or prolong the time of white rust.
冷却
cooling
防止工件激冷回缩,产生集体组织开裂。
Prevent the workpiece from chilling and retracting, resulting in collective structure cracking.
精整
Finishing
清除锌瘤及附着在镀层表面的锌灰
Remove zinc nodules and zinc dust attached to the coating surface
检验
test
镀层的检验和测定,工件的外观检查。
Inspection and measurement of coating and appearance inspection of workpiece.
