下面介绍一下铁艺大门的表面保护工艺：

The surface protection technology of iron gate is introduced below.

1、金属保护层：在铁艺制品表面镀上一层不易锈蚀的金属或者合金，常用方法有：电镀、喷镀、热浸镀等，但用于铁艺制品上的金属保护层一般应选用热浸镀锌为好。由于被镀工件镀前的除油去锈和在440摄氏度的锌熔液中高温浸镀，所以其镀层可掩盖许多缺陷和缝隙，避免以后泛锈，并有极好的附着性能。

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、非金属保护层：在铁艺制品表面涂装一层或数层有机和无机化合物，如油漆、塑料、橡胶、沥青、珐琅、耐酸材料、防锈油等。

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、化学保护层：用化学和电化学方法使铁艺制品表面形成一层非金属膜的保护层，如表面发黑、发蓝、磷酸盐处理等。

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：大门的焊接部位较多，必须认真每个焊接部位的焊渣。先用板锉或扁铁敲打除渣，然后用磨光机和砂布打磨焊缝，使其平滑。对飞溅到其他部位的焊渣也要顺势干净。

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，用磨光机和砂布打磨大门的各个组件，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、喷漆：喷漆前，用湿布擦净大门的各个部位，不能留有灰尘等。一道喷防锈漆，漆膜干透后喷第二道黑漆，更后喷一道清漆。注意不能有漏喷部位，也不能产生流挂等缺陷。个别细微处可用刷子刷涂补漆。

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.

以上介绍的是铁艺大门的表面保护工艺，希望大家有所了解。

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