每一次到地下停車(chē)庫，除了被豪車(chē)吸引外，還有頭頂上整整齊齊、一排排的、長(cháng)長(cháng)的，看不見(jiàn)頭、尾的矩形管。這叫通風(fēng)管，是消防必須要做的，通風(fēng)管在一般地下室中起到通風(fēng)、除濕的作用，地下車(chē)庫雖然不住人，但有人員進(jìn)出，所以同樣需要有適合人生存的空氣質(zhì)量；地下室的自然通風(fēng)口很少，一般只有出入口，是遠遠達不到所需要的通風(fēng)量的；更何況地下室往往濕氣大，特別是霉雨季節時(shí)，必須要有很強的通風(fēng)才能降低濕度。

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.

通風(fēng)管道的應用越來(lái)越普遍，常用的材質(zhì)有：

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

1、鋼板

鋼板是制造通風(fēng)管道和部件的主要材料，通常使用普通鋼板和鍍鋅鋼板兩種，鍍鋅鋼板表面有保護層，可防止腐蝕，主要用于防潮風(fēng)管系統。

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、不銹鋼板

不銹鋼板具有較高的塑性、韌性、機械強度和耐腐蝕性，常被用于化工領(lǐng)域的耐腐蝕風(fēng)管系統中。

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、鋁板

包括純鋁及合金鋁，普通合金鋁板機械強度高，耐腐蝕性差，通風(fēng)工程用鋁板大多為純鋁和退火合金鋁板，由干鋁板較軟，碰撞時(shí)無(wú)火花，多用于有防爆要求的通風(fēng)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、塑料復合鋼板

在普通鋼板上粘貼或噴涂一層塑料薄膜，即塑料復合鋼板，具有耐腐蝕、彎曲、咬合、鉆孔加工性能好等特點(diǎn)，常用于空氣凈化系統和通風(fēng)空調系統。

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、聚氬乙烯塑料板

PVC塑料板具有良好的耐腐蝕性，一般不與酸、堿、鹽發(fā)生反應，在通風(fēng)空調工程中，主要用作輸送酸、堿、鹽等腐蝕性氣體的管道和部件。

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、玻璃鋼

玻璃鋼風(fēng)管是一種輕質(zhì)，高強，耐腐蝕的非金屬管道，采用樹(shù)脂，玻璃纖維，石英砂為原料制成，廣泛應用干石油，化工及排水等行業(yè)。

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、復合材料

復合風(fēng)管是采用復合材料制作而成的風(fēng)管，有橡塑復合風(fēng)管、氯氧鎂通風(fēng)管道等多種，一般由兩層高強度無(wú)機材料和一層保溫材料為基材，采用膠粘技術(shù)和特殊的結構組合、連接。

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.

所以不同材質(zhì)的風(fēng)管性質(zhì)方面有所不同，一般在選擇風(fēng)管的時(shí)候，必須要考慮材質(zhì)的特點(diǎn)，是否適合當前施工環(huán)境，是否適合當前的施工目的以及效果，使用后通風(fēng)效率如何等因素，綜合衡量，選擇合適的材質(zhì)。

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.
