The following introduces the surface protection technology of Jinan Iron Gate:

　　1、金屬保護(hù)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(hù)層一般應(yīng)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 that is not easy to rust is plated on the surface of iron products. The common methods are electroplating, spray plating, hot dip galvanizing, etc., but hot dip galvanizing is generally preferred for the metal protective layer on iron products. Due to its excellent corrosion resistance in the bath and after plating, it can avoid many defects in the plating bath.

　　2、非金屬保護(hù)層：在鐵藝制品表面涂裝一層或數(shù)層有機(jī)和無(wú)機(jī)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, plastic, rubber, asphalt, enamel, acid resistant materials, antirust oil, etc.

　　3、化學(xué)保護(hù)層：用化學(xué)和電化學(xué)方法使鐵藝制品表面形成一層非金屬膜的保護(hù)層，如表面發(fā)黑、發(fā)藍(lán)、磷酸鹽處理等。

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

　　4、清除焊渣：大門的焊接部位較多，必須認(rèn)真清除每個(gè)焊接部位的焊渣。先用板銼或扁鐵敲打除渣，然后用磨光機(jī)和砂布打磨焊縫，使其平滑。對(duì)飛濺到其他部位的焊渣也要順勢(shì)清除干凈。

　　4. Remove welding slag: there are many welding parts in the gate, and the welding slag of each welding part must be removed carefully. First, use a plate file or flat iron to knock off the slag, and then use a polishing machine and abrasive cloth to polish the weld to make it smooth. The welding slag splashed to other parts should also be removed.

　　5、打磨原子灰：干透后，用磨光機(jī)和砂布全面打磨大門的各個(gè)組件，尤其是涂抹原子灰的部位更要磨光。

　　5. Grinding of putty: after drying, polish all components of the gate with polishing machine and emery cloth, especially the parts coated with putty.

　　6、噴漆：噴漆前，用濕布全面擦凈大門的各個(gè)部位，不能留有灰塵等。道噴防銹漆，漆膜干透后噴第二道黑漆，噴一道清漆。注意不能有漏噴部位，也不能產(chǎn)生流掛等缺陷。個(gè)別細(xì)微處可用刷子刷涂補(bǔ)漆。

　　6. Spray painting: before painting, wipe all parts of the gate with wet cloth, and no dust can be left. The first layer is sprayed with antirust paint, the second layer of black paint is sprayed after the film is dry, and the last layer of varnish is sprayed. Attention should be paid to no leakage or sagging. Some tiny parts can be applied with brush.
