一、材質類型與性能對比

1、 Comparison of Material Types and Performance

1. 鍍鋅薄鋼板風管

1. Galvanized steel sheet air duct

優點：

advantage:

強度高：承壓能力強，適用于高壓送風系統（如工業廠房、地鐵隧道）。

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

防火性能優異：不燃性 A 級，符合濟南消防規范要求（如人防工程需采用鍍鋅鋼板風管）。

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).

安裝靈活：可現場加工復雜形狀，適配老舊建筑改造（如濟南漢峪金谷地下通風工程）。

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).

缺點：

Disadvantages:

易腐蝕：濟南夏季潮濕多雨，未做防腐處理的鍍鋅層 2-3 年可能生銹（需定期刷防銹漆）。

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).

無消聲 / 保溫：需額外加裝消聲器和保溫層，增加成本（如濟南交通醫院新風系統）。

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. 無機玻璃鋼風管

2. Inorganic fiberglass air duct

優點：

advantage:

耐腐蝕性強：適用于酸堿環境（如濟南化工車間、污水處理廠）。

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

重量輕：安裝便捷，減少建筑承重（如濟南某造紙廠風管安裝）。

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

缺點：

Disadvantages:

易老化：長期暴曬或低溫環境下（如濟南冬季）可能脆化，壽命約 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.

防火隱患：有機玻璃鋼易燃，濟南消防要求優先選擇無機材質。

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

3. 復合玻纖板風管

3. Composite fiberglass board air duct

優點：

advantage:

消聲節能：管壁多孔結構可吸收設備噪聲，減少空調能耗（如濟南某商場空調系統）。

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).

保溫性好：導熱系數低（≤1W/m?K），減少冷量損失，符合濟南節能規范。

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

缺點：

Disadvantages:

強度不足：需配合金屬框架使用，大管徑（DN1000+）易變形。

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

防火風險：粘合劑若含可燃成分，可能影響整體耐火等級。

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

4. 纖維織物風管

4. Fiber fabric air duct

優點：

advantage:

防凝露：通過滲透性形成冷氣層，避免濟南夏季管道表面結露（如濟南某酒店廚房排煙系統）。

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).

安裝快速：柔性材質可繞過障礙物，適合復雜空間（如濟南地鐵 4 號線通風工程）。

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

缺點：

Disadvantages:

維護頻繁：油污易附著，需每季度清洗（如濟南某餐廳廚房管道）。

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

承壓低：僅適用于低壓送風（≤500Pa），無法用于工業高壓場景。

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

5. 不銹鋼風管

5. Stainless steel air duct

優點：

advantage:

高耐腐蝕性：適用于食品加工、醫藥行業（如濟南華熙制藥通風工程）。

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

壽命長：304 不銹鋼可使用 20 年以上，減少更換成本。

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

缺點：

Disadvantages:

成本高：價格是鍍鋅鋼板的 3-5 倍，經濟性差。

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

加工難度大：需專業設備，濟南本地供應商較少。

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