濟南電纜橋架表面防腐層如何選擇?

  工程設計中常見的第三個問題是電纜橋架的類型沒有標明防腐層的類型,也沒有統一的書面描述。這一問題在現實中是有教訓的,如我國在印尼承建一個總承包工程時,對鋼電纜橋架表面的腐蝕處理沒有進行鹽霧試驗,建成后不久橋梁就被嚴重腐蝕,不得不進行更換。電纜橋架表面防腐層主要有熱浸鋅、鍍鋅鎳、冷浸鋅、粉末靜電噴涂等。廠家數據顯示,熱浸鋅工藝壽命不低于40年,適用于室外重腐蝕環境,且成本較高。
  The third common problem in engineering design is that the type of cable tray does not indicate the type of anti-corrosion coating, and there is no unified written description. This problem has a lesson in reality. For example, when China contracted a general contract project in Indonesia, there was no salt spray test for the corrosion treatment of the steel cable bridge surface. Soon after the completion, the bridge was severely corroded and had to be replaced. The anticorrosive coating on the surface of cable tray mainly includes hot-dip galvanizing, galvanized nickel, cold-dip galvanizing, powder electrostatic spraying, etc. According to the manufacturer's data, the service life of hot-dip galvanizing process is not less than 40 years, which is suitable for outdoor heavy corrosion environment with high cost.

  鍍鋅鎳工藝壽命不小于30年,也適用于成本高、腐蝕嚴重的室外環境。冷鍍鋅工藝壽命不少于12年,適合戶外光腐蝕環境,成本一般;粉末靜電噴涂工藝壽命不少于12年,適合室內常溫干燥環境,價格一般。設計人員應根據工程環境條件合理選擇電纜橋架表面防腐層的類型,并在設計文件中明確表達。
  The service life of galvanizing nickel process is not less than 30 years, and it is also suitable for outdoor environment with high cost and serious corrosion. The service life of cold galvanizing process shall not be less than 12 years, which is suitable for outdoor light corrosion environment with general cost; the service life of powder electrostatic spraying process shall not be less than 12 years, which is suitable for indoor normal temperature and dry environment with general price. The designer shall reasonably select the type of anti-corrosion coating on the surface of cable tray according to the engineering environmental conditions and express it clearly in the design documents.
