济南铁艺护栏有哪些实用的防锈方法?

  济南铁艺护栏有哪些实用的防锈方法?目前,更有效、实用的防锈方法是热镀锌护栏。也就是说,在熔融锌液铁护栏的表面形成锌-铁合金层和纯锌层,以隔离铁工件氧化的机会。防锈期20 ~ 50年以上,在此期间不进行保养,安全可靠,是铸铁工件更好的防锈方法。
  At present, the most effective and practical anti-rust method is hot-dip galvanized guardrail. That is to say, zinc-iron alloy layer and pure zinc layer are formed on the surface of molten zinc iron guardrail to isolate the chance of oxidation of iron workpiece. The anti-rust period is more than 20 to 50 years, during which no maintenance is carried out. It is safe and reliable. It is the best anti-rust method for cast iron workpieces.
  热镀锌工艺流程
  Hot dip galvanizing process
  1. 酸洗前检查并处理
  1. Check and deal with before pickling
  检查铁制工件是否有工艺孔(排气、取用锌夜、悬挂),铁制工件表面腐蚀程度,表面覆盖物可用盐酸除去(如油漆、油脂等应采用防火、打磨、碱洗等方法除去)。
  Check whether there are process holes (exhaust, zinc night, suspension) in iron workpiece, the corrosion degree of iron workpiece surface, and the surface covering can be removed by hydrochloric acid (such as paint, grease, etc. should be removed by fire prevention, polishing, alkali washing, etc.).
  2. 脱脂(碱性洗涤)
  2. Degreasing (alkaline washing)
  配备加热设备,消除工件表面的铁油脂、油漆等。
  Equipped with heating equipment to eliminate the iron grease and paint on the surface of the workpiece.
  3.
  Three
  从铁制工件表面除去碱水和附件。
  Remove alkali water and accessories from the surface of iron workpieces.
  4,酸洗
  4. pickling
  清除锈迹、水垢和其他表面覆盖物
  Remove rust, scale and other surface coverings
  5.酸洗后检查及处理:
  5. Inspection and treatment after pickling:
  酸洗效果是否理想,如果酸洗不够充分,再酸洗一次,如果酸洗前处理不彻底,再酸洗一次后再处理。
  Whether the pickling effect is ideal, if the pickling is not enough, pickling again, if the pretreatment before pickling is not complete, pickling again after treatment.
  6.从铁制工件表面除去酸性水和其他附着物

  6. Remove acidic water and other attachments from the surface of iron workpieces
  7.上层助镀剂
  7. Super plating AIDS
  再次清洗工件表面,确保镀锌前工件表面不生锈。
  Clean the workpiece surface again to ensure that the workpiece surface is not rusty before galvanizing.
  8.干燥
  8. Drying
  提高铁质工件的温度,避免铁质工件表面水分过多,镀锌时发生爆炸。
  Raise the temperature of iron workpiece, avoid excessive moisture on the surface of iron workpiece and explosion when galvanizing.
  9.热浸锌
  9. Hot dipping zinc
  工件在440℃-470℃熔融锌液中浸泡,达到一定时间后,工件表面得到一层锌及铁合金层和纯锌层镀层。
  The workpiece was immersed in molten zinc solution at 440 - 470 C. After a certain time, a layer of zinc and ferroalloy coating and pure zinc coating were obtained on the workpiece surface.
  10.钝化
  10. Passivation
  提供工件表面对大气的耐腐蚀性,减少或延长白锈的时间。
  Provide corrosion resistance of workpiece surface to atmosphere, reduce or prolong white rust time.
  11.冷却
  11. Cooling
  防止工件受冷收缩,组织集体开裂。
  Prevent the cold shrinkage of the workpiece and the collective cracking of the organization.
  12.完成
  12. Completion
  清除附着在涂层表面的锌结节和锌粉
  Removal of zinc nodules and powders attached to the coating surface
  13.检验
  13. Inspection
  检查和确定涂层,检查工件外观。
  Check and determine the coating, check the appearance of the workpiece.
