一、材质类型与性能对比

1、 Comparison of Material Types and Performance

1. 镀锌薄钢板风管

1. Galvanized steel sheet air duct

优点：

advantage:

强度高：承压能力强，适用于高压送风系统（如工业厂房、地铁隧道）。

High strength: Strong pressure bearing capacity, suitable for high-pressure air supply systems (such as industrial plants and subway tunnels).

防火性能优异：不燃性 A 级，符合济南消防规范要求（如人防工程需采用镀锌钢板风管）。

Excellent fire resistance: Class A non flammability, meeting the requirements of Jinan fire safety regulations (such as galvanized steel sheet air ducts required for civil air defense projects).

安装灵活：可现场加工复杂形状，适配老旧建筑改造（如济南汉峪金谷地下通风工程）。

Flexible installation: capable of on-site processing of complex shapes, suitable for the renovation of old buildings (such as Jinan Hanyu Jingu underground ventilation project).

缺点：

Disadvantages:

易腐蚀：济南夏季潮湿多雨，未做防腐处理的镀锌层 2-3 年可能生锈（需定期刷防锈漆）。

Corrosion prone: Jinan is humid and rainy in summer, and the galvanized layer without anti-corrosion treatment may rust within 2-3 years (regular application of anti rust paint is required).

无消声 / 保温：需额外加装消声器和保温层，增加成本（如济南交通医院新风系统）。

No noise reduction/insulation: Additional mufflers and insulation layers need to be installed, which increases costs (such as the fresh air system of Jinan Traffic Hospital).

2. 无机玻璃钢风管

2. Inorganic fiberglass air duct

优点：

advantage:

耐腐蚀性强：适用于酸碱环境（如济南化工车间、污水处理厂）。

Strong corrosion resistance: suitable for acidic and alkaline environments (such as chemical workshops and sewage treatment plants in Jinan).

重量轻：安装便捷，减少建筑承重（如济南某造纸厂风管安装）。

Lightweight: Easy to install, reducing building load (such as installing air ducts in a paper mill in Jinan).

缺点：

Disadvantages:

易老化：长期暴晒或低温环境下（如济南冬季）可能脆化，寿命约 5-8 年。

Easy to age: Long term exposure to sunlight or low temperature environments (such as winter in Jinan) may cause brittleness, with a lifespan of about 5-8 years.

防火隐患：有机玻璃钢易燃，济南消防要求优先选择无机材质。

Fire hazard: Organic glass fiber reinforced plastic is flammable, and Jinan Fire Protection requires priority to choose inorganic materials.

3. 复合玻纤板风管

3. Composite fiberglass board air duct

优点：

advantage:

消声节能：管壁多孔结构可吸收设备噪声，减少空调能耗（如济南某商场空调系统）。

Noise reduction and energy saving: The porous structure of the pipe wall can absorb equipment noise and reduce air conditioning energy consumption (such as the air conditioning system in a shopping mall in Jinan).

保温性好：导热系数低（≤1W/m・K），减少冷量损失，符合济南节能规范。

Good insulation: low thermal conductivity (≤ 1W/m · K), reducing cooling loss, in line with Jinan energy-saving standards.

缺点：

Disadvantages:

强度不足：需配合金属框架使用，大管径（DN1000+）易变形。

Insufficient strength: It needs to be used in conjunction with a metal frame, as large pipe diameters (DN1000+) are prone to deformation.

防火风险：粘合剂若含可燃成分，可能影响整体耐火等级。

Fire risk: If the adhesive contains flammable components, it may affect the overall fire resistance rating.

4. 纤维织物风管

4. Fiber fabric air duct

优点：

advantage:

防凝露：通过渗透性形成冷气层，避免济南夏季管道表面结露（如济南某酒店厨房排烟系统）。

Anti condensation: Form a cold air layer through permeability to prevent condensation on the surface of pipes in Jinan during summer (such as the kitchen exhaust system of a hotel in Jinan).

安装快速：柔性材质可绕过障碍物，适合复杂空间（如济南地铁 4 号线通风工程）。

Quick installation: The flexible material can bypass obstacles and is suitable for complex spaces (such as the ventilation project of Jinan Metro Line 4).

缺点：

Disadvantages:

维护频繁：油污易附着，需每季度清洗（如济南某餐厅厨房管道）。

Frequent maintenance: Oil stains are prone to adhere and need to be cleaned quarterly (such as kitchen pipes in a restaurant in Jinan).

承压低：仅适用于低压送风（≤500Pa），无法用于工业高压场景。

Low pressure: only suitable for low-pressure air supply (≤ 500Pa), cannot be used in industrial high-pressure scenarios.

5. 不锈钢风管

5. Stainless steel air duct

优点：

advantage:

高耐腐蚀性：适用于食品加工、医药行业（如济南华熙制药通风工程）。

High corrosion resistance: suitable for food processing and pharmaceutical industries (such as Jinan Huaxi Pharmaceutical Ventilation Engineering).

寿命长：304 不锈钢可使用 20 年以上，减少更换成本。

Long lifespan: 304 stainless steel can be used for more than 20 years, reducing replacement costs.

缺点：

Disadvantages:

成本高：价格是镀锌钢板的 3-5 倍，经济性差。

High cost: The price is 3-5 times that of galvanized steel plate, and the economy is poor.

加工难度大：需专业设备，济南本地供应商较少。

Difficulty in processing: Professional equipment is required, and there are few local suppliers in Jinan.
