Galvanized air duct

鍍鋅風管呈現(xiàn)噪音，很大程度上其實就是按照物理原理，空氣活動越快，噪音的體現(xiàn)就越大。然后，在日常維護中，鍍鋅風管會有一定的注意事項。經常檢查鍍鋅風管設備的老化保護有很好的效果，也有助于降低噪音。

The galvanized air duct presents noise. To a large extent, according to the physical principle, the faster the air activity, the greater the noise. Then, in daily maintenance, there will be certain precautions for galvanized air duct. Often check the aging protection of galvanized air duct equipment, which has a good effect and helps to reduce noise.

因為鍍鋅風管廠家在使用時沒有很好的消聲功能，所以要給風管加消聲器，導熱系數太大，所以沒有保溫功能，所以在使用時需要再加一層保溫層，對使用環(huán)境也有要求不要在一些潮濕的環(huán)境附近使用，這樣鍍鋅風管往往會受到環(huán)境的影響而生銹。

Because the galvanized air duct manufacturer does not have a good silencing function when using, it is necessary to add a muffler to the air duct. The thermal conductivity is too large, so it has no thermal insulation function. Therefore, it is necessary to add another layer of thermal insulation layer when using. It also has requirements for the use environment. Do not use it near some humid environment, so the galvanized air duct will often rust under the influence of the environment.
