Hot dip galvanizing, galvanizing nickel, cold galvanizing and powder electrostatic spraying are the main types of anti-corrosion coatings on the surface of cable bridge in Shandong Province. Hot dip galvanizing can cover a dense and very thick protective layer on its surface. The contact between the steel body and some corrosive substances is completely avoided, and the steel body is protected from being damaged. The new surface will produce a kind of zinc salt after a long time, which is insoluble in water and has stronger recovery. Therefore, some projects in the marine salt fog atmosphere can also play a good role in protection. At the same time, the mixture of iron and zinc produced in the heating project has higher wear resistance. There are four common galvanizing methods:

1.熱浸鍍鋅

1. Hot dip galvanizing

鍍鋅作為一種犧牲陽極來保護陰極金屬的方法。其耐腐蝕壽命取決于鍍鋅層厚度和腐蝕速率。熱浸鍍鋅的鋅層厚度一般在65um(455g/m2)以上。鋅與鐵的結合面形成一層鋅鐵合金，增強了鋅層的附著力。在熱浸鍍鋅時容易產生變形等問題，需要在電纜橋架的結構上及鍍鋅工藝上加以考慮。

Zinc plating is a method of sacrificing anode to protect cathode metal. Its corrosion life depends on the thickness and corrosion rate of the galvanized layer. The thickness of hot dip galvanized zinc coating is generally over 65um (455g/m2). The binding surface of zinc and iron forms a layer of zinc-iron alloy, which enhances the adhesion of zinc layer. Deformation is easy to occur during hot dip galvanizing, which needs to be considered in the structure of cable bridge and galvanizing process.

2.電鍍鋅

2. Galvanizing

電鍍鋅與熱浸鍍鋅相比工藝簡單，成本較低。對電纜橋架的結構無特殊要求。電鍍鋅經鈍化處理后能夠顯著地提高其保護性能。電鍍鋅層一般在12/zm左右。因而不適用于耐腐蝕壽命要求較高的場合。

Compared with hot dip galvanizing, galvanizing has the advantages of simple process and low cost. There is no special requirement for the structure of cable bridge. After passivation treatment, the protective performance of electroplated zinc can be significantly improved. The galvanized layer is generally about 12/zm. Therefore, it is not suitable for the occasion with high corrosion life requirements.

3.靜電噴涂

3. Electrostatic Spraying

噴涂材料一般為聚氯乙烯粉末，聚脂粉末或防腐粉末。涂層厚度在100/1rn 左右。靜電噴涂具有外表美觀、防化學腐蝕性能好的特點。

Spraying materials are usually polyvinyl chloride powder, polyester powder or anti-corrosion powder. The thickness of the coating is about 100/1rn. Electrostatic spraying has the characteristics of beautiful appearance and good chemical corrosion resistance.

4.涂防銹漆

4. Antirust paint

對于結構尺寸較大的構件，由于受鋅鍋、鍍槽、烘箱等的限制，一般只能采用涂防銹漆的方法來處理。它雖然具有成本低、使用方便等特點;但防腐蝕能力較差。使用壽命短，維護工作量大。

Because of the limitation of zinc pot, galvanizing bath, oven and so on, rust-proof paint can only be used to treat the large-sized components. Although it has the characteristics of low cost and easy to use, its anti-corrosion ability is poor. Short service life and heavy maintenance workload.

以上就是山東電纜橋架在防腐上做的工作，通過上述的介紹你是不是有了一定的了解了呢。漢杰橋架廠主要有QJ系列電纜橋架分為梯式、托盤式、槽式及組合式四種。主營產品有防火橋架，不銹鋼橋架、玻璃鋼橋架、鋁合金橋架、大跨距橋架等。

The above is the anti-corrosion work of Shandong cable bridge, through the above introduction, do you have a certain understanding? Hanjie Bridge Frame Factory mainly has QJ Series Cable Bridge Frame which is divided into ladder type, tray type, trough type and combination type. The main products are fire-proof bridge, stainless steel bridge, FRP bridge, aluminum alloy bridge, long-span bridge, etc.
