  铁艺护栏的防锈处理及防锈工艺流程
  Antirust treatment and process flow of iron guardrail
  目前铁艺护栏有效、实用的防锈方法是热浸镀锌。即在铁艺护栏在熔化的锌液中在表面生成锌铁合金层及纯锌层,用以隔绝铁艺工件被氧化的机会。防锈期长达20-50年以上,期间无需维修,安全可靠,是铁艺工件的比较好的防锈方法。
  At present, hot dip galvanizing is an effective and practical anti rust method for iron fence. In other words, the ferroalloy layer and pure zinc layer are formed on the surface of the iron fence in the molten zinc to isolate the opportunity of iron work piece being oxidized. The antirust period is more than 20-50 years without maintenance. It is safe and reliable. It is a good antirust method for iron work pieces.
  热浸镀锌的工艺流程
  Technological process of hot dip galvanizing
  1、酸洗前检查处理
  1. 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 galvanizing process hole of our factory (exhaust, zinc in and out night, hanging), the rust degree of the iron work piece surface, whether the surface covering can be removed by hydrochloric acid (if there is paint, grease, etc., it should be removed by fire, grinding, alkali washing, etc.).
  2、脱脂(碱洗)
  2. 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.
  3、水洗
  3. Wash with water
  清除铁艺工件表面的碱水及附着物。
  Remove alkali water and attachments on the surface of iron work pieces.

  4、酸洗
  4. Pickling
  除去铁锈、氧化皮等其它表面覆盖物
  Remove rust, scale and other surface coverings
  5、酸洗后检查处理:
  5. 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 not sufficient, pickling again; if the pretreatment before pickling is not complete, the pickling should be conducted again after re treatment.
  6、水洗
  6. Wash with water
  除去铁艺工件表面的酸水及其它附着物
  Remove acid water and other attachments on the surface of iron work pieces
  7、上助镀剂
  7. Plating AIDS
  再次清洗工件表面,保证表面在镀锌之前不在生锈。
  Clean the surface of the workpiece again to ensure that the surface does not rust before galvanizing.
  8、烘干
  8. Drying
  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。
  Increase the temperature of iron work piece to avoid excessive moisture on the iron surface and explosion during galvanizing.
  9、热浸锌
  9. 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。
  When the workpiece is immersed in molten zinc at 440 ℃ - 470 ℃ for a certain period of time, a layer of zinc iron alloy layer and pure zinc layer are obtained on the surface of iron work piece.
  10、钝化
  10. 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。
  It can reduce or prolong the time of white rust.
  11、冷却
  11. Cooling
  防止工件激冷回缩,产生集体组织开裂。
  To prevent the workpiece from cold shrinkage and collective structure cracking.
  12、精整
  12. 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 surface of the coating
  12、检验
  12. Inspection
  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.
