下面介紹一下鐵藝大門的表面保護工藝：

The surface protection technology of iron gate is introduced below.

1、金屬保護層：在鐵藝制品表面鍍上一層不易銹蝕的金屬或者合金，常用方法有：電鍍、噴鍍、熱浸鍍等，但用于鐵藝制品上的金屬保護層一般應選用熱浸鍍鋅為好。由于被鍍工件鍍前的除油去銹和在440攝氏度的鋅熔液中高溫浸鍍，所以其鍍層可掩蓋許多缺陷和縫隙，避免以后泛銹，并有極好的附著性能。

1. Metal protective layer: A layer of metal or alloy which is not easy to rust is coated on the surface of iron products. Common methods are: electroplating, spraying, hot dipping, etc. However, hot dipping galvanizing is generally preferred for the metal protective layer used on iron products. Because of the professional degreasing and rust removal before plating and high temperature dipping in 440 degrees Celsius zinc melt, the coating can cover up many defects and cracks, avoid rusting later, and has excellent adhesion performance.

2、非金屬保護層：在鐵藝制品表面涂裝一層或數層有機和無機化合物，如油漆、塑料、橡膠、瀝青、琺瑯、耐酸材料、防銹油等。

2. Non-metallic protective layer: Coating one or more layers of organic and inorganic compounds on the surface of iron products, such as paint, plastics, rubber, asphalt, enamel, acid-resistant materials, rust-proof oil, etc.

3、化學保護層：用化學和電化學方法使鐵藝制品表面形成一層非金屬膜的保護層，如表面發黑、發藍、磷酸鹽處理等。

3. Chemical protective layer: A protective layer of non-metallic film is formed on the surface of iron products by chemical and electrochemical methods, such as surface blackening, bluing, phosphate treatment, etc.

4、焊渣：大門的焊接部位較多，必須認真每個焊接部位的焊渣。先用板銼或扁鐵敲打除渣，然后用磨光機和砂布打磨焊縫，使其平滑。對飛濺到其他部位的焊渣也要順勢干凈。

4. Clean up the welding slag: There are many welding parts in the gate, so we must carefully remove the welding slag in each welding part. First, slag is knocked out with a plate file or flat iron, and then weld seam is polished with a polisher and abrasive cloth to make it smooth. The welding slag splashed to other parts should also be cleaned up.

 

5、打磨原子灰：干透后，用磨光機和砂布打磨大門的各個組件，尤其是涂抹原子灰的部位更要磨光。

5. Grinding Atomic Ash: After drying out, use a polisher and abrasive cloth to completely polish the various components of the door, especially the parts coated with Atomic Ash.

6、噴漆：噴漆前，用濕布擦凈大門的各個部位，不能留有灰塵等。一道噴防銹漆，漆膜干透后噴第二道黑漆，更后噴一道清漆。注意不能有漏噴部位，也不能產生流掛等缺陷。個別細微處可用刷子刷涂補漆。

6. Spray paint: before spray paint, wipe all parts of the door with wet cloth, no dust and so on. The first sprays rust-proof paint, the second sprays black paint after the film is dry, and the last sprays a varnish. Attention should be paid not to the leakage of spray parts, nor to the flow hanging and other defects. Brush brushes can be used for repairing individual details.

以上介紹的是鐵藝大門的表面保護工藝，希望大家有所了解。

Above is the surface protection technology of iron gate, I hope you have some understanding.
