鍍鋅鐵皮風管適合大尺寸加工，機械加工方便，但小尺寸時由于不方便采用機械設(shè)備，因此加工周期長，速度慢。另外，鍍鋅鐵皮風管施工時不好控制安裝精度；大小通等配件不易制作；安裝難度大，對施工人員的要求高。

The galvanized iron sheet air duct is suitable for large size processing, which is convenient for machining. However, it is not convenient to use mechanical equipment for small size processing, so the Makespan is long and the speed is slow. In addition, it is difficult to control the installation accuracy during the construction of galvanized iron sheet air ducts; Accessories such as large and small ones are not easy to make; The installation difficulty is high, and the requirements for construction personnel are high.

鍍鋅鐵皮風管（采用20mm橡塑保溫材料的導(dǎo)熱系數(shù)卻高達0。035-0。043W/（m/K），而且當鍍鋅鐵皮風管的保溫材料長期接觸空氣時，還會出現(xiàn)吸濕的現(xiàn)象，使得鍍鋅鐵皮風管的導(dǎo)熱系數(shù)大大增加。

Galvanized iron sheet air duct (using 20mm rubber plastic insulation material, the thermal conductivity is as high as 0.035-0.043W/(m/K), and when the insulation material of galvanized iron sheet air duct is in long-term contact with air, it will also experience moisture absorption, greatly increasing the thermal conductivity of galvanized iron sheet air duct.

鍍鋅鐵皮為無機材料，防火性能好，為不燃A級，但其外部經(jīng)常采用橡塑類保溫材料(應(yīng)用于工業(yè)和建筑)。大大降低了鍍鋅鐵皮風管的防火等級。

Galvanized iron sheet is an inorganic material with good fire resistance and is classified as non combustible Grade A. However, its exterior often uses rubber plastic insulation materials (used in industry and construction). Greatly reduces the fire rating of galvanized iron sheet air ducts.

鍍鋅鐵皮風管的外部需要在現(xiàn)場包裹一層保溫層，而且在進行維修時還常常需要更換保溫層，因此除風管本身的高度外，還需要預(yù)留一定的安裝和維修空間。

The exterior of the galvanized iron sheet air duct needs to be wrapped with an insulation layer on site, and the insulation layer often needs to be replaced during maintenance. Therefore, in addition to the height of the air duct itself, a certain amount of installation and maintenance space needs to be reserved.

濟南鐵皮風管加工廠家提醒您，鍍鋅鐵皮在潮濕環(huán)境中容易生銹，而鍍鋅鐵皮風管常用的另一種保溫材料玻璃纖維吸濕后易變脆，因此鍍鋅鐵皮風管的使用的時長大約只有5～10年左右。

Jinan iron sheet air duct processing manufacturer reminds you that galvanized iron sheet is prone to rust in humid environments, while another commonly used insulation material for galvanized iron sheet air ducts, glass fiber, is prone to brittleness after moisture absorption. Therefore, the service life of galvanized iron sheet air ducts is only about 5-10 years.

鍍鋅鐵皮風管是一種剛性風管，沒有消聲效果，它甚還會將設(shè)備的噪聲傳送到工作地點，因此需要加消聲罩和消聲彎頭之類的消聲配件。更多相關(guān)事項就來我們網(wǎng)站http://rdhw.com.cn咨詢！

Galvanized iron sheet air duct is a type of rigid air duct that has no noise reduction effect. It can even transmit equipment noise to the workplace, so noise reduction accessories such as noise reduction covers and elbows need to be added.
