专注通风管道加工·排烟罩

通常使用镀锌风管，不锈钢管用于腐蚀性和特别潮湿的地方。当环境空气湿度较高时，风道外壁应进行防腐防锈处理。输送高温高湿的风道内壁应喷涂磷化底漆或其他防腐涂料。当风道输送高温气体或低温空气时，风道外壁应进行保温（冷保）处理。

Galvanized air ducts are usually used, while stainless steel pipes are used in corrosive and particularly humid areas. When the ambient air humidity is high, the outer wall of the air duct should be treated with anti-corrosion and rust prevention. The inner wall of the air duct conveying high temperature and high humidity should be sprayed with phosphating primer or other anti-corrosion coatings. When the air duct transports high-temperature gas or low-temperature air, the outer wall of the air duct should be insulated (cold preserved).

输送高温气体的风道的隔热目的是防止管道中空气的热量损失（冬季出现在集中式空调系统中）。在输送废热蒸汽或高温气体时，为了防止热量传递到室内并使室温升高，可以防止人再次接触风管并烫伤。在夏季，当输送气体的温度低于周围环境的空气露点温度时，通风管道外壁会产生冷凝现象。空调系统的空气管道会增加冷却损失，冷凝水滴会污染天花板和墙壁地板。因此，还应进行冷却和隔热处理。

The insulation purpose of the air duct transporting high-temperature gas is to prevent heat loss of the air in the pipeline (which occurs in centralized air conditioning systems in winter). When transporting waste heat steam or high-temperature gas, in order to prevent heat from being transferred indoors and raise the room temperature, it is possible to prevent people from coming into contact with the air duct again and getting burned. In summer, when the temperature of the transported gas is lower than the dew point temperature of the surrounding air, condensation will occur on the outer wall of the ventilation duct. The air ducts of the central air conditioning system will increase cooling losses, and condensation droplets will contaminate the ceiling and walls and floors. Therefore, cooling and insulation treatment should also be carried out.

以上是通风管道防腐保温的原因。只有防腐才能减少后期使用中的腐蚀，所以我们应该注意这些方面，并尽量保证在以后使用时更光滑，效果更好。

The above are the reasons for the anti-corrosion and insulation of ventilation ducts. Only anti-corrosion can reduce corrosion in later use, so we should pay attention to these aspects and try to ensure smoother and better results in future use.
