每一次到地下停车库，除了被豪车吸引外，还有头顶上整整齐齐、一排排的、长长的，看不见头、尾的矩形管。这叫通风管，是消防必须要做的，通风管在一般地下室中起到通风、除湿的作用，地下车库虽然不住人，但有人员进出，所以同样需要有适合人生存的空气质量；地下室的自然通风口很少，一般只有出入口，是远远达不到所需要的通风量的；更何况地下室往往湿气大，特别是霉雨季节时，必须要有很强的通风才能降低湿度。

Every time to the underground parking garage, in addition to being attracted by luxury cars, there are neat, rows, long, invisible to the head and tail rectangular pipe. This is called ventilation pipe, fire must do, ventilation pipe in ventilation, dehumidification in general basement, underground garage, although there are people in and out, so also need to have human air quality; the basement natural ventilation is very few, generally only entrance and exit, is far less than of the required ventilation capacity; and the basement often moisture, especially in the rainy season, must have strong ventilation to reduce the humidity.

通风管道的应用越来越普遍，常用的材质有：

The application of ventilation duct is becoming more and more common. The commonly used materials are:

1、钢板

钢板是制造通风管道和部件的主要材料，通常使用普通钢板和镀锌钢板两种，镀锌钢板表面有保护层，可防止腐蚀，主要用于防潮风管系统。

1. Steel plate

Steel plate is the main material for manufacturing ventilation pipes and components, usually using ordinary steel plate and galvanized steel sheet. The galvanized steel sheet has a protective layer that can prevent corrosion, mainly used for moisture-proof air duct system.

2、不锈钢板

不锈钢板具有较高的塑性、韧性、机械强度和耐腐蚀性，常被用于化工领域的耐腐蚀风管系统中。

2. Stainless steel plate

Stainless steel plate has high plasticity, toughness, mechanical strength and corrosion resistance, and is often used in the corrosion resistant air duct system in the chemical field.

3、铝板

包括纯铝及合金铝，普通合金铝板机械强度高，耐腐蚀性差，通风工程用铝板大多为纯铝和退火合金铝板，由干铝板较软，碰撞时无火花，多用于有防爆要求的通风管道。

3. Aluminum board

Including pure aluminum and alloy aluminum, ordinary alloy aluminum plate has high mechanical strength and poor corrosion resistance. Most of the aluminum plate for ventilation engineering are pure aluminum and annealed alloy aluminum plate, with of dry aluminum plate and no spark in collision, and it is mostly used for ventilation pipes with explosion-proof requirements.

4、塑料复合钢板

在普通钢板上粘贴或喷涂一层塑料薄膜，即塑料复合钢板，具有耐腐蚀、弯曲、咬合、钻孔加工性能好等特点，常用于空气净化系统和通风空调系统。

4. Plastic composite steel plate

Paste or spray a layer of plastic film on the ordinary steel plate, that is, plastic composite steel plate, has corrosion resistance, bending, occlusion, drilling processing performance and other characteristics, commonly used in air purification system and ventilation and air conditioning system.

5、聚氩乙烯塑料板

PVC塑料板具有良好的耐腐蚀性，一般不与酸、碱、盐发生反应，在通风空调工程中，主要用作输送酸、碱、盐等腐蚀性气体的管道和部件。

5, polyargon ethylene plastic plate

PVC Plastic board has good corrosion resistance, generally do not react with acid, alkali, salt, in the ventilation and air conditioning engineering, mainly used to transport acid, alkali, salt and other corrosive gas pipes and components.

6、玻璃钢

玻璃钢风管是一种轻质，高强，耐腐蚀的非金属管道，采用树脂，玻璃纤维，石英砂为原料制成，广泛应用干石油，化工及排水等行业。

6.FRP

FRP air duct is a kind of light, high strength, corrosion resistant non-metal pipe, using resin, glass fiber, quartz sand as raw materials, widely used in dry oil, chemical and drainage industries.

7、复合材料

复合风管是采用复合材料制作而成的风管，有橡塑复合风管、氯氧镁通风管道等多种，一般由两层高强度无机材料和一层保温材料为基材，采用胶粘技术和特殊的结构组合、连接。

7. Composites

Composite air duct is made of composite materials, rubber and plastic composite air duct, magnesium chloride ventilation pipe and so on, generally composed of two layers of high strength inorganic material and a layer of insulation material as the base material, using adhesive technology and special structure combination, connection.

所以不同材质的风管性质方面有所不同，一般在选择风管的时候，必须要考虑材质的特点，是否适合当前施工环境，是否适合当前的施工目的以及效果，使用后通风效率如何等因素，综合衡量，选择合适的材质。

Therefore, the properties of the duct of different materials are different. Generally, when choosing the duct, we must consider the characteristics of the material, whether it is suitable for the current construction environment, whether it is suitable for the current construction purpose and effect, how the ventilation efficiency after use and other factors, comprehensive measurement, choose the appropriate material.
