你知道济南铁艺护栏的表面保护工艺是怎样的吗？实际上如果您要使用该产品，就需要知道这个问题，有利于施工质量的提高。

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.金属保护层：在其表面涂上一层不易生锈的金属或合金。常见的方法包括电镀、喷涂、热浸镀锌等，但用于产品的金属保护层通常应为热浸镀锌。由于在电镀前对待镀工件进行脱脂和除锈，以及在440℃的锌熔体中进行高温浸镀，涂层可以覆盖许多缺陷和间隙，避免将来生锈，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.非金属保护层：铁护栏表面应涂一层或多层化合物，如油漆、塑料、橡胶、沥青、搪瓷、耐酸材料、防锈油等。

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.化学保护层：通过化学和电化学方法在其表面形成的非金属膜的保护层，如表面发黑、发蓝等。

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：产品的焊接部位很多，因此有必要仔细清除每个焊接部位的焊渣。首先，用板锉或扁铁敲击并清除熔渣，然后用抛光机和砂布打磨焊缝，使其光滑。飞溅到其他部位的焊渣也应清除。

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.打磨腻子：待腻子干燥后，用抛光机和砂布打磨每个部件，并注意涂有腻子的部分。

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.喷漆：喷漆前，用湿布擦拭铁护栏的所有部分，以避免灰尘。先喷防锈漆，待漆膜干燥后再喷黑漆，再喷一层清漆。需要注意的是，不得有漏件、流挂等缺陷，一些小零件可以用刷子修补。

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.
