很多人會根據自己的需求來定制鐵藝護欄，定制的話會滿足自己的要求更好的使用，通常需求對室外鐵藝護欄進行熱浸鍍鋅處理。那么室外鐵藝護欄的熱浸鍍鋅定制工藝好不好？下面了解下吧。

　　Many people will customize the iron guardrail according to their own needs, customized words will meet their own requirements for better use, usually need to hot-dip galvanized outdoor iron guardrail. So outdoor iron guardrail hot dip galvanized custom process is good? Let's take a look.

　　室外鐵藝護欄外層的油漆表面或多或少會受到損壞。 即使漆面受損，鍍鋅層也不易腐蝕生銹。 如果不進行熱鍍鋅，日后漆面損壞時，鐵方管會直接與雨水等物質接觸。 時間長了很容易生銹，大大降低了鐵藝護欄的使用壽命。

　　Outdoor iron fence outer paint surface more or less will be damaged. Even if the paint surface is damaged, the galvanizing layer is not easy to corrosion and rust. If hot dip galvanizing is not carried out, the iron square pipe will come into direct contact with rain water and other substances in the future when the paint surface is damaged. For a long time, it is easy to rust, greatly reducing the service life of the iron guardrail.

　　酸洗前檢查工藝，看鐵制品是否有工廠鍍鋅工藝孔，鐵表面的腐蝕程度，表面覆蓋的罐頭材料是否可以去除； 配備加熱設備進行脫脂（堿洗）、熨斗表面消除潤滑脂、油漆等； 用水清洗，去除工件的堿鐵安裝面；酸洗以去除表面上的其他鐵銹、水垢和其他覆蓋物；用水去除鐵質工件表面的酸堿等附件，再用助焊劑清洗外觀，保證鍍鋅前的外觀不生銹。

　　Before pickling, check the process to see whether the iron products have galvanized process holes in the factory, the corrosion degree of the iron surface, and whether the canning materials covered on the surface can be removed; Equipped with heating equipment for degreasing (alkali washing), iron surface to eliminate grease, paint, etc. Clean with water to remove the alkali iron mounting surface of the workpiece; Pickling to remove other rust, scale and other coverings from the surface; Remove the acid and alkali and other accessories on the surface of iron workpiece with water, and then clean the appearance with flux to ensure that the appearance is not rusty before galvanizing.

　　烘干提高鐵質工件的溫度，防止濟南鐵藝護欄鐵皮表面水分過多和鍍鋅時爆炸；將熱鍍鋅工件浸入440℃-470℃的熔融鋅浴中，經過一定時間的供給，在鐵質工件表面獲得一層。鋅鐵合金層和一層純鋅涂層；當白銹減少或擴大時，鈍化工件的表面電阻以提供大氣腐蝕性能；冷卻工件，防止冷縮，造成集體結構開裂；并整理去除附著在鋅灰表面的鍍鋅層；測試和測量電鍍工件的外觀檢查。

　　Drying to improve the temperature of iron workpiece, prevent ji 'nan iron fence iron surface moisture and galvanized explosion; Dip the hot-dip galvanized workpiece into the molten zinc bath of 440℃-470℃, after a certain period of supply, obtain a layer on the surface of the iron workpiece. Zinc-ferroalloy layer and a layer of pure zinc coating; When white rust is reduced or expanded, the surface resistance of the workpiece is passivated to provide atmospheric corrosion performance; Cooling workpiece, prevent cold shrinkage, resulting in collective structure cracking; And clean and remove the zinc layer attached to the surface of zinc ash; Test and measure the appearance inspection of electroplating parts.

　　經過以上的內容了解，我們知道了室外鐵藝護欄的熱浸鍍鋅定制工藝確實好，起到的作用還是比較大的，那么就要在實際操作中多多注意一些事項了。更多內容就來我們網站www.4hut75.com咨詢吧！
