    1、消声性能;
    1. Anechoic performance;
    镀锌薄钢板风管:无消声性能,自身震动会产生声音,必须加装消声器。
    Galvanized steel sheet air duct: no sound attenuation performance, its vibration will produce sound, must be equipped with muffler.
    无机玻璃钢风管:无消声性能,隔声性能优于镀锌薄钢板风管,必须加装消声器。
    Inorganic glass fiber reinforced plastic air duct: no sound attenuation performance, sound insulation performance is better than galvanized steel sheet air duct, must be equipped with muffler.
    复合玻纤板风管:其管壁是一种多孔性吸声材料,可省去专用消声器。
    Composite fiberglass board air duct: its wall is a kind of porous sound-absorbing material, so special muffler can be omitted.
    2、保温性能:
    2. Thermal insulation performance:
    镀锌薄钢板风管:导热系数很大(为60.4 W/m?K) ,无保温性能,必须另外加包保温层及保护层。
    Galvanized steel sheet air duct: the thermal conductivity is very large (60.4 w / M? K), and it has no thermal insulation performance. Therefore, it is necessary to add thermal insulation layer and protective layer.
    复合玻纤板风管:导热系数小(平均温度24℃时小于1 W/m?K) ,有一定保温性能,不加装保温。
    Composite fiberglass board air duct: small thermal conductivity (less than 1 W / M? K when the average temperature is 24 ℃), with certain thermal insulation performance, without adding thermal insulation.

    3、防火性能
    3. Fire performance
    镀锌薄钢板风管:不燃,但其真正的防火性能视保温层而定。
    Galvanized steel sheet air duct: non combustible, but its real fire performance depends on the insulation layer.
    无机玻璃钢风管:同镀锌薄钢板风管。
    Inorganic glass fiber reinforced plastic air duct: the same as galvanized steel sheet air duct.
    复合玻纤板风管:外层为铝箔,以不燃性玻璃纤维棉板为基材,防火性能好。
    Composite fiberglass board air duct: the outer layer is aluminum foil, and the non combustible glass fiber cotton board is used as the base material, with good fire resistance.
    4、防潮性能
    4. Moisture resistance
    镀锌薄钢板风管:易受潮腐蚀生锈。
    Galvanized steel sheet air duct: easy to be affected by moisture, corrosion and rust.
    无机玻璃钢风管:受原料配比的制约,其防潮性能的稳定性较差。
    Inorganic glass fiber reinforced plastic air duct: restricted by the proportion of raw materials, the stability of its moisture-proof performance is poor.
    复合玻纤板风管:无易腐材料和部件,但因其为多孔材料,在长期潮湿环境下不建议使用。
    Composite fiberglass board air duct: no perishable materials and components, but due to its porous material, it is not recommended to use in long-term humid environment.
    5、强度
    5. Strength
    镀锌薄钢板风管:强度较高,抗静压能力强。
    Galvanized steel sheet air duct: high strength, strong static pressure resistance.
    无机玻璃钢风管:强度较高,抗冲击能力脆弱。
    Inorganic glass fiber reinforced plastic air duct: high strength, weak impact resistance.
    复合玻纤板风管:能满足一般通风空调的承压要求,高可承受风压1500Pa。
    Composite fiberglass board air duct: it can meet the pressure bearing requirements of general ventilation and air conditioning, and can withstand wind pressure of 1500pa.
