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(fēng)管道在運(yùn)輸過(guò)程中應(yīng)注意防止鍍鋅風(fēng)管受到損壞。玻璃鋼復(fù)合板鍍鋅風(fēng)管端口為開(kāi)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(fēng)管的加工性能好，而鍍鋅風(fēng)管的封閉性好，很多客戶選擇鍍鋅風(fēng)管是因?yàn)槠浣?jīng)濟(jì)效率高，鍍鋅風(fēng)管在生產(chǎn)過(guò)程中節(jié)省材料，鍍鋅風(fēng)管不僅在制造的時(shí)候省工省料，而且在運(yùn)轉(zhuǎn)的時(shí)候由于質(zhì)量比其它風(fēng)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(fēng)管鍍鋅層經(jīng)過(guò)鈍化處理，染色或涂護(hù)色劑后，可明顯改善其防護(hù)裝飾性能。另外鍍鋅風(fēng)管的防火性能首先體現(xiàn)在，它具有不燃性，不過(guò)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(guò)本文可以了解到鍍鋅風(fēng)管的耐火性能在很多方面都能體現(xiàn)出來(lái)，同樣在使用鍍鋅風(fēng)管時(shí)也沒(méi)有良好的消聲功能，所以我們要給風(fēng)管加上消聲器，而其導(dǎo)熱率偏高，因此沒(méi)有保溫功能，所以我們?cè)谑褂脮r(shí)還需要另加包保溫層，對(duì)于應(yīng)用環(huán)境也有要求，不能將其應(yīng)用于某些潮濕性較大的環(huán)境中，這樣往往容易讓鍍鋅風(fēng)管受到環(huán)境的影響而容易出現(xiàn)銹蝕現(xiàn)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.
