風管是通風系統(tǒng)中的重要組成，其常見的類型主要有：鍍鋅薄鋼板風管；無機玻璃鋼風管；復合玻纖板風管；纖維織物風管；哪種風管比較好，需要根據實際使用的環(huán)境和需求決定，下面濟南風管加工廠將四種風管的性能比較分析：

Air ducts are an important component of ventilation systems, and their common types include: galvanized steel sheet air ducts; Inorganic fiberglass air duct; Composite fiberglass board air duct; Fiber fabric air duct; Which type of air duct is better depends on the actual usage environment and needs. Below, Jinan Air duct Processing Factory will compare and analyze the performance of the four types of air ducts:

消聲性能：

Sound attenuation performance:

鍍鋅薄鋼板風管：風管自身震動易產生噪音，須加裝對應的消聲器。

Galvanized thin steel plate air duct: The air duct itself is prone to vibration and noise, and corresponding silencers must be installed.

無機玻璃鋼風管：其隔聲性能相對于鍍鋅薄鋼板風管來說要強，但也需要加裝消聲器。

Inorganic fiberglass duct: Its sound insulation performance is stronger than that of galvanized thin steel duct, but it also requires the installation of a silencer.

復合玻纖板風管：其管壁材料具有多孔性吸聲的能力，因此可以不用加裝消聲器。

Composite fiberglass board air duct: Its wall material has the ability of porous sound absorption, so there is no need to install a muffler.

纖維織物風管：其管壁的柔性材料，本身不產生噪音，且具有良好的吸音性能，此外，其還可以吸收一定程度的設備噪聲，管道越長消音效果越明顯。

Fiber fabric air duct: The flexible material of its pipe wall does not generate noise and has good sound absorption performance. In addition, it can also absorb a certain degree of equipment noise, and the longer the pipeline, the more obvious the noise reduction effect.

保溫性能：

Insulation performance:

鍍鋅薄鋼板風管：導熱系數(shù)大，因此風管的保溫性差，需要加裝保溫層。

Galvanized thin steel plate air duct: Due to its high thermal conductivity, the insulation of the air duct is poor and requires the installation of an insulation layer.

無機玻璃鋼風管：導熱系數(shù)較大，因此也需要加裝保溫

Inorganic fiberglass duct: with a high thermal conductivity, it is also necessary to install insulation

復合玻纖板風管：在平均24℃的溫度下，導熱系數(shù)不超過1W/m?K，通常不加裝保溫層。

Composite fiberglass board air duct: At an average temperature of 24 ℃, the thermal conductivity does not exceed 1W/m? K. Usually no insulation layer is added.

纖維織物風管：通常需要犧牲低于10%的冷量，以避免風管表面凝露，形成冷氣層，確保管壁內外不存在溫差。

Fiber fabric air duct: Usually, it is necessary to sacrifice less than 10% of the cooling capacity to avoid condensation on the surface of the duct, forming a cold air layer, and ensuring that there is no temperature difference between the inside and outside of the duct wall.

防火性能

Fire performance

鍍鋅薄鋼板風管：不燃，可能需要不燃材料的保溫層。

Galvanized thin steel plate air duct: Non combustible, may require insulation layer of non combustible materials.

無機玻璃鋼風管：同上。

Inorganic fiberglass duct: Ditto.

復合玻纖板風管：其基材采用不燃性玻璃纖維棉板，本身具有防火性能，但實際使用中還要考慮風管的黏合劑,xps風管等方面的因素。

Composite fiberglass board air duct: Its substrate is made of non combustible fiberglass cotton board, which has inherent fire resistance. However, in practical use, factors such as adhesive and xps air duct should also be considered.

纖維織物風管：一般采用新型阻燃纖維，符合B級防火標準。對于防火要求高的可以選用A級防火標準。

Fiber fabric air duct: Generally, new flame-retardant fibers are used, meeting the B-level fire protection standard. For those with high fire protection requirements, A-level fire protection standards can be selected.

4、防潮性能

4. Moisture resistance

鍍鋅薄鋼板風管：輸送介質含濕量較大時，易發(fā)生腐蝕生銹

Galvanized thin steel plate air duct: When the moisture content of the conveying medium is high, it is prone to corrosion and rust

無機玻璃鋼風管：其防潮性能受到原料配比的影響；

Inorganic fiberglass duct: Its moisture-proof performance is affected by the proportion of raw materials;

復合玻纖板風管：多孔材料管道，其內部、管端和切口不宜長期浸泡。

Composite fiberglass board air duct: Porous material pipes should not be soaked for a long time in their interior, pipe ends, and incisions.

纖維織物風管：表面有冷氣層、且材料具有強疏水性，因此不易受潮。

Fiber fabric air duct: With a cold air layer on the surface and strong hydrophobicity of the material, it is not susceptible to moisture.

風管強度

Air duct strength

鍍鋅薄鋼板風管：具有較高的強度和抗靜壓能力，但斷面尺寸較大，仍需要根據規(guī)定加固。

Galvanized thin steel plate air duct: It has high strength and static pressure resistance, but the cross-sectional size is large and still needs to be reinforced according to regulations.

無機玻璃鋼風管：具有較高強度，但材料較重，搬運過程中易發(fā)生酥裂和破損。

Inorganic fiberglass air duct: It has high strength, but the material is heavy and prone to cracking and damage during transportation.

復合玻纖板風管：能夠承受1500Pa的風壓。

Composite fiberglass board air duct: capable of withstanding wind pressure up to 1500Pa.

纖維織物風管：材料韌性好，能夠耐受2000Pa的壓力。

Fiber fabric air duct: The material has good toughness and can withstand a pressure of 2000Pa.
