鐵藝護欄除銹有什么技巧?

  目前,有效實用的鐵藝護欄防銹方法是熱鍍鋅。即在熔融鋅液中,在鍛鐵護欄的表面上形成鋅鐵合金層和純鋅層,以隔離鍛鐵護欄氧化的機會。防銹期長達20-50年,無需維護,安全可靠。是鍛鐵護欄方法的良好防銹劑。下面就讓我們一起來了解一下吧。希望能幫到大家。
  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.
  熱浸鍍鋅的工藝流程:
  Hot dip galvanizing process flow:
  1、酸洗前檢查處理
  1. Inspection and treatment before pickling
  檢查鐵藝護欄是否具備本廠鍍鋅的工藝孔,護欄表面的銹蝕程度,表面覆蓋物能否被鹽酸除去。
  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、脫脂
  2. Degreasing
  配有加熱設(shè)備,消除護欄表面的油脂、涂料等。
  Equipped with heating equipment to eliminate grease and coating on the surface of guardrail.
  3、水洗
  3. Wash with water
  清除護欄表面的堿水及附著物。
  Remove alkali water and attachments on the surface of guardrail.
  4、酸洗
  4. Pickling
  除去鐵銹、氧化皮等其它表面覆蓋物
  Remove rust, scale and other surface coverings

  5、酸洗后檢查處理:
  5. Inspection and treatment after pickling:
  酸洗效果是否理想,如酸洗不充分,再次酸洗,如果酸洗前處理不干凈,需重新處理后再次酸洗。
  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
  除去護欄表面的酸水及其它附著物
  Remove acid water and other attachments on the surface of guardrail
  7、上助鍍劑
  7. Plating AIDS
  再次清洗護欄表面,保證表面在鍍鋅之前不在生銹。
  Clean the surface of guardrail again to ensure that the surface will not rust before galvanizing.
  8、烘干
  8. Drying
  提高護欄的溫度,避免鐵藝表面水分過多和鍍鋅時爆炸。
  Increase the temperature of the guardrail to avoid excessive moisture on the iron surface and explosion when galvanizing.
  9、熱浸鋅
  9. Hot dip galvanizing
  將護欄在440~ 470的熔融鋅溶液中浸泡一定時間后,在護欄表面獲得了鋅鐵合金層和純鋅層。
  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、鈍化
  10. Passivation
  提供護欄表面的耐大氣腐蝕性能,減少或延長白銹的出現(xiàn)時間。
  Provide atmospheric corrosion resistance of guardrail surface to reduce or prolong the occurrence time of white rust.
  11、冷卻
  11. Cooling
  防止護欄冷卻和回縮,導(dǎo)致集體組織開裂。
  To prevent the guardrail from cooling and retraction, resulting in collective tissue cracking.
  12、調(diào)整
  12. Adjustment
  清除附著在涂層表面的鋅瘤和鋅粉
  Remove zinc nodules and zinc powder attached to the coating surface
  13、檢查
  13. Inspection
  涂層的檢查和測定,護欄的目視檢查。
  Inspection and measurement of coating and visual inspection of guardrail.
  以上是對鐵藝護欄防銹處理和防銹過程的介紹,希望對大家有所幫助。鐵藝護欄的日常除銹處理非常重要,希望大家能夠重視起來,這不僅僅能延長鐵藝護欄的使用壽命,還能降低鐵藝護欄使用成本。
  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.
