铁艺护栏除锈有什么技巧?

来源:http://www.jnghbxg.com 日期:2020-09-15 发布人:yangxiang 浏览次数:
  目前,有效实用的铁艺护栏防锈方法是热镀锌。即在熔融锌液中,在锻铁护栏的表面上形成锌铁合金层和纯锌层,以隔离锻铁护栏氧化的机会。防锈期长达20-50年,无需维护,安全可靠。是锻铁护栏方法的良好防锈剂。下面就让我们一起来了解一下吧。希望能帮到大家。
  At present, hot galvanizing is an effective and practical anti rust method for iron fence. In other words, zinc iron alloy layer and pure zinc layer are formed on the surface of forged iron guardrail in molten zinc to isolate the oxidation opportunity of forged iron guardrail. Antirust period up to 20-50 years, no maintenance, safe and reliable. It is a good antirust agent for forged iron guardrail. Let's take a look at it. I hope it can help you.
  热浸镀锌的工艺流程:
  Hot dip galvanizing process flow:
  1、酸洗前检查处理
  1. Inspection and treatment before pickling
  检查铁艺护栏是否具备本厂镀锌的工艺孔,护栏表面的锈蚀程度,表面覆盖物能否被盐酸除去。
  Check whether the iron guardrail has the galvanized process hole of our factory, the corrosion degree of the guardrail surface, and whether the surface covering can be removed by hydrochloric acid.
  2、脱脂
  2. Degreasing
  配有加热设备,消除护栏表面的油脂、涂料等。
  Equipped with heating equipment to eliminate grease and coating on the surface of guardrail.
  3、水洗
  3. Wash with water
  清除护栏表面的碱水及附着物。
  Remove alkali water and attachments on the surface of guardrail.
  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,如果酸洗前处理不干净,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 clean, the pickling should be conducted again after reprocessing.
  6、水洗
  6. Wash with water
  除去护栏表面的酸水及其它附着物
  Remove acid water and other attachments on the surface of guardrail
  7、上助镀剂
  7. Plating AIDS
  再次清洗护栏表面,保证表面在镀锌之前不在生锈。
  Clean the surface of guardrail again to ensure that the surface will not rust before galvanizing.
  8、烘干
  8. Drying
  提高护栏的温度,避免铁艺表面水分过多和镀锌时爆炸。
  Increase the temperature of the guardrail to avoid excessive moisture on the iron surface and explosion when galvanizing.
  9、热浸锌
  9. Hot dip galvanizing
  将护栏在440~ 470的熔融锌溶液中浸泡一定时间后,在护栏表面获得了锌铁合金层和纯锌层。
  After soaking the guardrail in molten zinc solution of 440 ~ 470 for a certain period of time, the zinc iron alloy layer and pure zinc layer were obtained on the guardrail surface.
  10、钝化
  10. Passivation
  提供护栏表面的耐大气腐蚀性能,减少或延长白锈的出现时间。
  Provide atmospheric corrosion resistance of guardrail surface to reduce or prolong the occurrence time of white rust.
  11、冷却
  11. Cooling
  防止护栏冷却和回缩,导致集体组织开裂。
  To prevent the guardrail from cooling and retraction, resulting in collective tissue cracking.
  12、调整
  12. Adjustment
  清除附着在涂层表面的锌瘤和锌粉
  Remove zinc nodules and zinc powder attached to the coating surface
  13、检查
  13. Inspection
  涂层的检查和测定,护栏的目视检查。
  Inspection and measurement of coating and visual inspection of guardrail.
  以上是对铁艺护栏防锈处理和防锈过程的介绍,希望对大家有所帮助。铁艺护栏的日常除锈处理非常重要,希望大家能够重视起来,这不仅仅能延长铁艺护栏的使用寿命,还能降低铁艺护栏使用成本。
  The above is the introduction of rust prevention treatment and rust prevention process of iron guardrail, I hope to help you. The daily derusting treatment of the iron fence is very important, I hope you can pay attention to it, which can not only prolong the service life of the iron fence, but also reduce the use cost of the iron fence.
