來源:http://www.fsjt-gov.com 日期:2025-04-09 發(fā)布人:創(chuàng)始人
一、材質(zhì)類型與性能對(duì)比
1、 Comparison of Material Types and Performance
1. 鍍鋅薄鋼板風(fēng)管
1. Galvanized steel sheet air duct
優(yōu)點(diǎn):
advantage:
強(qiáng)度高:承壓能力強(qiáng),適用于高壓送風(fēng)系統(tǒng)(如工業(yè)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(yōu)異:不燃性 A 級(jí),符合濟(jì)南消防規(guī)范要求(如人防工程需采用鍍鋅鋼板風(fēng)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(xiàn)場加工復(fù)雜形狀,適配老舊建筑改造(如濟(jì)南漢峪金谷地下通風(fēng)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(diǎn):
Disadvantages:
易腐蝕:濟(jì)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(jì)南交通醫(yī)院新風(fēng)系統(tǒng))。
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(jī)玻璃鋼風(fēng)管
2. Inorganic fiberglass air duct
優(yōu)點(diǎn):
advantage:
耐腐蝕性強(qiáng):適用于酸堿環(huán)境(如濟(jì)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(jì)南某造紙廠風(fēng)管安裝)。
Lightweight: Easy to install, reducing building load (such as installing air ducts in a paper mill in Jinan).
缺點(diǎn):
Disadvantages:
易老化:長期暴曬或低溫環(huán)境下(如濟(jì)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(jī)玻璃鋼易燃,濟(jì)南消防要求優(yōu)先選擇無機(jī)材質(zhì)。
Fire hazard: Organic glass fiber reinforced plastic is flammable, and Jinan Fire Protection requires priority to choose inorganic materials.
3. 復(fù)合玻纖板風(fēng)管
3. Composite fiberglass board air duct
優(yōu)點(diǎn):
advantage:
消聲節(jié)能:管壁多孔結(jié)構(gòu)可吸收設(shè)備噪聲,減少空調(diào)能耗(如濟(jì)南某商場空調(diào)系統(tǒng))。
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(dǎo)熱系數(shù)低(≤1W/m?K),減少冷量損失,符合濟(jì)南節(jié)能規(guī)范。
Good insulation: low thermal conductivity (≤ 1W/m · K), reducing cooling loss, in line with Jinan energy-saving standards.
缺點(diǎn):
Disadvantages:
強(qiáng)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(fēng)險(xiǎn):粘合劑若含可燃成分,可能影響整體耐火等級(jí)。
Fire risk: If the adhesive contains flammable components, it may affect the overall fire resistance rating.
4. 纖維織物風(fēng)管
4. Fiber fabric air duct
優(yōu)點(diǎn):
advantage:
防凝露:通過滲透性形成冷氣層,避免濟(jì)南夏季管道表面結(jié)露(如濟(jì)南某酒店廚房排煙系統(tǒng))。
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(zhì)可繞過障礙物,適合復(fù)雜空間(如濟(jì)南地鐵 4 號(hào)線通風(fēng)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(diǎn):
Disadvantages:
維護(hù)頻繁:油污易附著,需每季度清洗(如濟(jì)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(fēng)(≤500Pa),無法用于工業(yè)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(fēng)管
5. Stainless steel air duct
優(yōu)點(diǎn):
advantage:
高耐腐蝕性:適用于食品加工、醫(yī)藥行業(yè)(如濟(jì)南華熙制藥通風(fēng)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(diǎn):
Disadvantages:
成本高:價(jià)格是鍍鋅鋼板的 3-5 倍,經(jīng)濟(jì)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(yè)設(shè)備,濟(jì)南本地供應(yīng)商較少。
Difficulty in processing: Professional equipment is required, and there are few local suppliers in Jinan.
