通風管道按用途區分

The ventilation pipes are divided according to their purposes

1、凈化空調系統用風管：鍍鋅板、不銹鋼；（使用中可能出現塵源污染的玻璃鋼、復合材料禁用）2、空調系統用風管：鍍鋅板、彩鋼保溫板；（可使用玻璃鋼、復合材料）3、環境控制系統用風管：鍍鋅板、不銹鋼；（可使用塑料、玻璃鋼、復合材料）4、工業通風系統用風管：鋼板、鍍鋅板；（麗博通風管.可使用塑料、玻璃鋼、復合材料）注：玻璃鋼風管可分有機、無機二種，根據設計規范有消防要求的禁用有機材質；5、特殊使用場合用風管：礦用涂膠布風筒、礦用塑料通風管；（要求阻燃抗靜電礦用安全特性）

1. Air duct for purification air conditioning system: galvanized sheet, stainless steel; (FRP and composite materials that may cause dust source pollution during use are prohibited) 2. Air duct for central air-conditioning system: galvanized sheet, color steel insulation board; (FRP and composite materials can be used) 3.

Plastic, glass fiber reinforced plastic and composite materials can be used) Note: glass fiber reinforced plastic air pipe can be divided into organic and inorganic materials, and organic materials are prohibited if there are fire protection requirements according to the design specifications; 5. Air duct for special occasions: mining adhesive coated air duct, mining plastic air duct; (Flame retardant and anti-static mining safety characteristics are required)

通風管道風管施工

Air duct construction

1）對于比較復雜的民用建筑，在設計階段，各工種（暖通、給水排水，供電照明與建筑）首先應協商好空間分隔，定出每種管道的標高范圍。一般情況下不得越出給自己規定的界限。遇有個別管段要越界時應與其他工程協商。2）解決各種通風管道相碰及協調的原則，一般為：“小管讓大管，有壓讓無壓”。例如，自來水管與風管相撞，則應當自來水管拐彎。冷、熱水管與下水管相碰，則應改變冷、熱水管道。3）施工前應設備總管的工程師，將各工種的管線，單線畫在一張平面圖上。每種管道用一種彩色筆。在各交點處綜合其標高，看是否有矛盾之處，及時發現，將問題解決在安裝之前。4）為了減少投資，節省空間，降低層高，有些敷設無坡度要求的管道，可以穿梁敷設（如自來水管道，消防噴灑干管等）。

1) For more complex civil buildings, in the design phase, all types of work (HVAC, water supply and drainage, power supply and lighting and architecture) should first negotiate space separation and determine the elevation range of each type of pipe. In general, you should not exceed the limits set for yourself. In case of pipeline section crossing the boundary, it shall negotiate with other projects. 2) The principle to solve the collision and coordination of various ventilation pipes is generally: "small pipes give way to large ones, and pressure gives way to no pressure". For example, if the water pipe collides with the air pipe, the water pipe should turn. If the cold and hot water pipes collide with the sewer pipe, the cold and hot water pipes shall be changed. 3) Before construction, the engineer in charge of equipment shall draw the pipelines and single lines of each type of work on a plan. One color pen for each type of pipe. The elevation of each intersection shall be integrated to see if there is any contradiction, and the problem shall be solved before installation. 4) In order to reduce investment, save space and reduce floor height, some pipes without slope requirements can be laid through beams (such as water supply pipes, fire sprinkler main pipes, etc.).

通風管道無機玻璃鋼

Inorganic glass fiber reinforced plastic for ventilation duct

無機玻璃鋼通風管（又稱玻璃纖維氯氧鎂水泥通風管）是以氯氧鎂水泥為膠結料中堿玻璃纖維為增強材料、加入填充材料和改性劑等所制成的一種管材。它具有不燃燒、屬不燃材料A級，耐腐蝕、強度高和重量輕等特點。在建筑工程、地下工程及工業廠房的通風中，它已經完全取代了不耐燃的有機玻璃鋼通風管，并在逐步取代防腐性能差的鍍鋅鐵皮通風管。尤其是在濕度大的地下工程和長江以南地區，它的優越性更為顯著。通過氯氧鎂膠凝材料的研究及制品的檢測，發現無機玻璃鋼通風管在生產中及工程應用中仍存在一些質量問題。有的質量問題嚴重影響了工程的使用壽命，應引起大家足夠重視。

Inorganic glass fiber reinforced plastic ventilation pipe (also known as glass fiber magnesium oxychloride cement ventilation pipe) is a pipe made of magnesium oxychloride cement as the binder, alkali glass fiber as the reinforcement, filler materials and modifiers. It has the characteristics of incombustible, Class A incombustible material, 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. Especially in the underground projects with high humidity and the areas south of the Yangtze River, its advantages are more significant. Through the research of magnesium oxychloride cementitious materials and the detection of products, it is found that there are still some quality problems in the production and engineering application of inorganic FRP ventilation pipes. Some quality problems seriously affect the service life of the project, which should be paid enough attention to.
