電纜橋架的表面防腐層類別有哪些呢？實際上主要有熱浸鋅、鍍鋅鎳、冷鍍鋅、粉末靜電噴涂等方式。濟南電纜橋架生產廠家資料顯示：

What are the types of anti-corrosion coating on the surface of cable tray? In fact, there are mainly hot dip galvanizing, zinc nickel plating, cold galvanizing, powder electrostatic spraying and other methods. According to the data of cable bridge manufacturers in Jinan:

數據表明，熱浸鍍鋅的工藝壽命不少于40年，適用于室外重度腐蝕環境，成本高；鍍鋅鎳的工藝壽命不少于30年，也適合于室外重度腐蝕環境，成本高；冷鍍鋅工藝壽命不少于12年，適用于戶外輕腐蝕的環境，成本是普通的；粉末靜電噴涂工藝的使用壽命不少于12年，適用于室內室溫干燥的環境，價格一般。

The data shows that the service life of hot-dip galvanizing process is not less than 40 years, and it is suitable for outdoor severely corrosive environment with high cost; The service life of zinc nickel plating process shall not be less than 30 years, and it is also suitable for outdoor severe corrosion environment with high cost; The service life of cold galvanizing process shall not be less than 12 years, which is suitable for outdoor light corrosion environment, and the cost is ordinary; The service life of powder electrostatic spraying process shall not be less than 12 years, and it is suitable for indoor room temperature and dry environment, with average price.

對鋼表面進行化學清潔，然后將其放入含有氧化鋅的電鍍液中。直流電在一處連接到鋼，鋅板在一處連接到電鍍液中。通電后，鋅以分子狀態被置換到鋼表面。如果加入增白劑進行鈍化，它將反射出彩色的云狀明亮涂層。

The steel surface is chemically cleaned and then placed in an electroplating solution containing zinc oxide. Direct current is connected to steel and zinc plate is connected to electroplating solution at one place. After electrification, zinc is replaced on the steel surface in a molecular state. If a whitening agent is added for passivation, it will reflect a colorful cloud like bright coating.

應用于鋼結構的鍍鋅鋅通常沒有良好的防銹效果，主要是因為未達到鍍鋅量，并且鍍鋅不均勻。通常，生銹發生在兩到三年內，并且質量差的產品會暴露在潮濕的環境中，并且會在十天內生銹。熱浸鍍鋅層較厚且具有較強的耐腐蝕性。冷浸鍍鋅層比熱浸鍍鋅層亮，但更薄且抗腐蝕性較弱。

Galvanized zinc applied to steel structures usually has no good rust prevention effect, mainly because the amount of galvanizing is not reached and the galvanizing is uneven. Generally, rust occurs within two to three years, and products of poor quality will be exposed to humid environment and rust within ten days. The hot-dip galvanized layer is thick and has strong corrosion resistance. Cold dip galvanized coating is brighter than hot dip galvanized coating, but thinner and less corrosion resistant.

工程設計中的三個普遍問題是熱浸鋅電纜橋架的類型沒有標記防腐蝕層的類型，并且沒有統一的文字描述。這個問題實際上是一個教訓。

Three common problems in engineering design are that the type of hot-dip galvanized cable tray is not marked with the type of anti-corrosion coating, and there is no unified text description. This question is actually a lesson.

設計人員應該根據工程環境條件合理選擇電纜橋架的表面防腐層類別，并在設計文件中清晰地表達。電纜橋架在有防火要求的區段內，可在電纜梯架、托盤內添加具有耐火或難燃性能的板、網等材料構成封閉或半封閉式結構，并采取在橋架及其支吊架表面涂刷防火涂層等措施，其整體耐火性能應滿足國家有關規范或標準的要求。

The designer shall reasonably select the type of anti-corrosion coating on the surface of cable tray according to the environmental conditions of the project, and clearly express it in the design documents. In the section with fire protection requirements for cable bridge, plates, nets and other materials with fire resistance or flame retardant properties can be added in cable ladder and tray to form a closed or semi closed structure, and measures such as painting fire retardant coating on the surface of cable bridge and its supports and hangers shall be taken. The overall fire resistance shall meet the requirements of relevant national codes or standards.
