Galvanized air duct, a good ventilation duct, is very well used in industry. The seller said that galvanized air duct also has good fire resistance, but we don't know what aspects this is mainly reflected in. Today, Xiaobian will tell you in detail.

鍍鋅風管道在運輸過程中應注意防止鍍鋅風管受到損壞。玻璃鋼復合板鍍鋅風管端口為開口型面，在組裝法蘭連接件之前，要用膠帶或膠水封好，才能防止玻璃纖維外露或飛散。

The galvanized air duct shall be protected from damage during transportation. The galvanized air duct end of FRP composite plate is an open profile. Before assembling the flange connector, it should be sealed with tape or glue to prevent the glass fiber from being exposed or scattered.

鍍鋅風管的加工性能好，而鍍鋅風管的封閉性好，很多客戶選擇鍍鋅風管是因為其經濟效率高，鍍鋅風管在生產過程中節省材料，鍍鋅風管不僅在制造的時候省工省料，而且在運轉的時候由于質量比其它風管要輕一些，所以成本較低。

Galvanized air duct has good processing performance and good sealing performance. Many customers choose galvanized air duct because of its high economic efficiency. Galvanized air duct saves materials in the production process. Galvanized air duct not only saves labor and materials in manufacturing, but also has lower cost because its quality is lighter than other air ducts in operation.

了解到鍍鋅風管鍍鋅層經過鈍化處理，染色或涂護色劑后，可明顯改善其防護裝飾性能。另外鍍鋅風管的防火性能首先體現在，它具有不燃性，不過需要稍微注意一下，其保溫層是否燃燒要依材料而定。

It is learned that the protective and decorative performance of galvanized air duct can be significantly improved after passivation, dyeing or coating with color protection agent. In addition, the fire protection performance of galvanized air duct is first reflected in that it is incombustible. However, it needs to be noted that whether its insulation layer burns depends on the material.

通過本文可以了解到鍍鋅風管的耐火性能在很多方面都能體現出來，同樣在使用鍍鋅風管時也沒有良好的消聲功能，所以我們要給風管加上消聲器，而其導熱率偏高，因此沒有保溫功能，所以我們在使用時還需要另加包保溫層，對于應用環境也有要求，不能將其應用于某些潮濕性較大的環境中，這樣往往容易讓鍍鋅風管受到環境的影響而容易出現銹蝕現象，這一切都是需要注意的。

Through this paper, we can know that the fire resistance of galvanized air duct can be reflected in many aspects. Similarly, when using galvanized air duct, there is no good silencing function, so we need to add muffler to the air duct, and its thermal conductivity is high, so there is no thermal insulation function. Therefore, we need to add another thermal insulation layer when using it, and there are requirements for the application environment, It can not be applied to some humid environments, so it is often easy for the galvanized air duct to be affected by the environment and prone to corrosion, all of which need to be paid attention to.
