风管是通风系统中的重要组成，其常见的类型主要有：镀锌薄钢板风管；无机玻璃钢风管；复合玻纤板风管；纤维织物风管；哪种风管比较好，需要根据实际使用的环境和需求决定，下面澳门正版内部资料大公开风管加工厂将四种风管的性能比较分析：

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:

消声性能：

Sound attenuation performance:

镀锌薄钢板风管：风管自身震动易产生噪音，须加装对应的消声器。

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

无机玻璃钢风管：其隔声性能相对于镀锌薄钢板风管来说要强，但也需要加装消声器。

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.

复合玻纤板风管：其管壁材料具有多孔性吸声的能力，因此可以不用加装消声器。

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

纤维织物风管：其管壁的柔性材料，本身不产生噪音，且具有良好的吸音性能，此外，其还可以吸收一定程度的设备噪声，管道越长消音效果越明显。

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.

保温性能：

Insulation performance:

镀锌薄钢板风管：导热系数大，因此风管的保温性差，需要加装保温层。

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.

无机玻璃钢风管：导热系数较大，因此也需要加装保温

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

复合玻纤板风管：在平均24℃的温度下，导热系数不超过1W/m?K，通常不加装保温层。

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.

纤维织物风管：通常需要牺牲低于10%的冷量，以避免风管表面凝露，形成冷气层，确保管壁内外不存在温差。

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

镀锌薄钢板风管：不燃，可能需要不燃材料的保温层。

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

无机玻璃钢风管：同上。

Inorganic fiberglass duct: Ditto.

复合玻纤板风管：其基材采用不燃性玻璃纤维棉板，本身具有防火性能，但实际使用中还要考虑风管的黏合剂,xps风管等方面的因素。

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.

纤维织物风管：一般采用新型阻燃纤维，符合B级防火标准。对于防火要求高的可以选用A级防火标准。

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

镀锌薄钢板风管：输送介质含湿量较大时，易发生腐蚀生锈

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

无机玻璃钢风管：其防潮性能受到原料配比的影响；

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

复合玻纤板风管：多孔材料管道，其内部、管端和切口不宜长期浸泡。

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

纤维织物风管：表面有冷气层、且材料具有强疏水性，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.

风管强度

Air duct strength

镀锌薄钢板风管：具有较高的强度和抗静压能力，但断面尺寸较大，仍需要根据规定加固。

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.

无机玻璃钢风管：具有较高强度，但材料较重，搬运过程中易发生酥裂和破损。

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

复合玻纤板风管：能够承受1500Pa的风压。

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

纤维织物风管：材料韧性好，能够耐受2000Pa的压力。

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