你知道濟南鐵藝護欄的表面保護工藝是怎樣的嗎？實際上如果您要使用該產品，就需要知道這個問題，有利于施工質量的提高。

Do you know what the surface protection technology of Jinan Iron Barrier is? In fact, if you want to use this product, you need to know this problem, which is conducive to the improvement of construction quality.

1.金屬保護層：在其表面涂上一層不易生銹的金屬或合金。常見的方法包括電鍍、噴涂、熱浸鍍鋅等，但用于產品的金屬保護層通常應為熱浸鍍鋅。由于在電鍍前對待鍍工件進行脫脂和除銹，以及在440℃的鋅熔體中進行高溫浸鍍，涂層可以覆蓋許多缺陷和間隙，避免將來生銹，并具有良好的粘附功能。

1. Metal protective layer: apply a layer of metal or alloy that is not easy to rust on its surface. Common methods include electroplating, spraying, hot dip galvanizing, etc., but the metal protective layer used for products should generally be hot dip galvanizing. As the workpiece to be plated is degreased and derusted before electroplating, and the coating is dipped in 440 ℃ zinc melt at high temperature, the coating can cover many defects and gaps, avoid future rust, and has a good adhesion function.

2.非金屬保護層：鐵護欄表面應涂一層或多層化合物，如油漆、塑料、橡膠、瀝青、搪瓷、耐酸材料、防銹油等。

2. Non metal protective layer: the surface of iron guardrail shall be coated with one or more layers of compound, such as paint, plastic, rubber, asphalt, enamel, acid resistant materials, antirust oil, etc.

3.化學保護層：通過化學和電化學方法在其表面形成的非金屬膜的保護層，如表面發黑、發藍等。

3. Chemical protective layer: the protective layer of non-metallic film formed on its surface by chemical and electrochemical methods, such as surface blackening, bluing, etc.

4.清除焊渣：產品的焊接部位很多，因此有必要仔細清除每個焊接部位的焊渣。首先，用板銼或扁鐵敲擊并清除熔渣，然后用拋光機和砂布打磨焊縫，使其光滑。飛濺到其他部位的焊渣也應清除。

4. Removal of welding slag: there are many welding parts of the product, so it is necessary to carefully remove the welding slag from each welding part. First, use a file or flat iron to knock and remove the slag, and then use a polishing machine and emery cloth to polish the weld to make it smooth. The welding slag splashed to other parts shall also be removed.

5.打磨膩子：待膩子干燥后，用拋光機和砂布打磨每個部件，并注意涂有膩子的部分。

5. Polishing putty: after the putty is dry, polish each part with a polishing machine and abrasive cloth, and pay attention to the part coated with putty.

6.噴漆：噴漆前，用濕布擦拭鐵護欄的所有部分，以避免灰塵。先噴防銹漆，待漆膜干燥后再噴黑漆，再噴一層清漆。需要注意的是，不得有漏件、流掛等缺陷，一些小零件可以用刷子修補。

6. Painting: Before painting, wipe all parts of the iron guardrail with a damp cloth to avoid dust. Spray antirust paint first, spray black paint after the paint film is dry, and then spray a layer of varnish. It should be noted that there should be no missing parts, sagging and other defects, and some small parts can be repaired with a brush.
