玻璃鋼通風(fēng)管是以氯氧鎂水泥為膠凝材料，堿性玻璃纖維為增強(qiáng)材料，添加填充材料和改性劑制成的一種管材。它是不燃的，A級(jí)不燃材料，具有耐腐蝕，強(qiáng)度高，重量輕的特點(diǎn)。在建筑工程、地下工程及工業(yè)廠房的通風(fēng)中，它已經(jīng)完全取代了不耐燃的有機(jī)玻璃鋼通風(fēng)管，并在逐步取代防腐性能差的鍍鋅鐵皮通風(fēng)管。濟(jì)南通風(fēng)管道廠家表示，尤其是在濕度大的地下工程和長(zhǎng)江以南地區(qū)，它的優(yōu)越性更為顯著。
Fiberglass ventilation pipe is a kind of pipe made of magnesium oxychloride cement as cementitious material, alkaline glass fiber as reinforcing material, filler materials and modifiers. It is incombustible, Class A incombustible material, characterized by corrosion resistance, high strength and light weight. In the ventilation of construction projects, underground projects and industrial plants, it has completely replaced the non flame resistant PMMA ventilation pipe, and gradually replaced the galvanized iron ventilation pipe with poor anti-corrosion performance. Jinan ventilation pipe manufacturer said that its advantages are more obvious, especially in underground projects with high humidity and in areas south of the Yangtze River.
玻璃鋼通風(fēng)管道產(chǎn)品特點(diǎn)：
Features of FRP ventilation pipe products:
(1)耐腐蝕性：使用化學(xué)惰性的材料，耐腐蝕性優(yōu)異，并可根據(jù)輸送介質(zhì)選擇不同的耐腐蝕管道;
(1) Corrosion resistance: chemical inert materials are used with excellent corrosion resistance, and different corrosion resistant pipes can be selected according to the transmission medium;
(2)機(jī)械強(qiáng)度大：耐水壓強(qiáng)度大，耐外壓強(qiáng)度和耐沖擊強(qiáng)度均良好并可按要求的壓力設(shè)計(jì)制造管道和管件 ;
(2) High mechanical strength: high water pressure resistance, good external pressure resistance and impact resistance, and pipes and fittings can be designed and manufactured according to the required pressure;
(3)溫度適應(yīng)性強(qiáng)：使用溫度范圍：大于-70攝氏度小于250攝氏度，冰凍介質(zhì)下管道不裂;
(3) Strong temperature adaptability: the operating temperature range is more than - 70 ℃ but less than 250 ℃, and the pipeline will not crack under the frozen medium;
(4)流體阻力?。河捎诠艿纼?nèi)壁是光滑的，粗糙系數(shù)0.0084,相同流量下,管徑可予縮小;
(4) Small fluid resistance: because the inner wall of the pipe is smooth with a roughness coefficient of 0.0084, the pipe diameter can be reduced under the same flow rate;
(5)重量輕，壽命長(zhǎng)：質(zhì)地非常輕，運(yùn)輸便利，施工費(fèi)用低，無須維修，可使用50年以上;
(5) Light weight, long service life: very light texture, convenient transportation, low construction cost, no maintenance, can be used for more than 50 years;
(6)保持水質(zhì)：，輸送飲水用水，能保持長(zhǎng)期水質(zhì)衛(wèi)生。
(6) Maintain water quality: non-toxic, transport drinking water, can maintain long-term water quality and sanitation.
