眾所周知，通風管道的基本用途是輸送新鮮空氣和廢氣，將有害氣體排出室外，并將新鮮空氣送到房間。在使用通風管道安裝時需要做好防腐保溫，那么有什么需要做呢？
山東通風管道廠家為您介紹：
As we all know, the basic purpose of ventilation duct is to convey fresh air and waste gas, discharge harmful gases out of the room, and send fresh air to the room. When installing the ventilation pipe, it is necessary to do a good job of anti-corrosion and insulation, so what needs to be done? Shandong ventilation pipe manufacturer introduces to you:
通常使用鍍鋅風管，不銹鋼管用于腐蝕性和特別潮濕的地方。當環境空氣濕度較高時，風道外壁應進行防腐防銹處理。輸送高溫高濕的風道內壁應噴涂磷化底漆或其他防腐涂料。當風道輸送高溫氣體或低溫空氣時，風道外壁應進行保溫（冷保）處理。
Galvanized air duct is usually used, and stainless steel pipe is used in corrosive and especially humid places. When the ambient air humidity is high, the outer wall of the air duct shall be subject to anti-corrosion and anti-rust treatment. The inner wall of air duct conveying high temperature and high humidity shall be sprayed with phosphating primer or other anti-corrosion coating. When the air duct transports high-temperature gas or low-temperature air, the outer wall of the air duct shall be subject to thermal insulation (cold insulation) treatment.
輸送高溫氣體的風道的隔熱目的是防止管道中空氣的熱量損失（冬季出現在集中式空調系統中）。在輸送廢熱蒸汽或高溫氣體時，為了防止熱量傳遞到室內并使室溫升高，可以防止人再次接觸風管并燙傷。
The purpose of heat insulation of the air duct conveying high-temperature gas is to prevent the heat loss of the air in the duct (which occurs in the centralized air conditioning system in winter). When transporting waste heat steam or high-temperature gas, in order to prevent heat transfer to the room and raise the room temperature, people can be prevented from contacting the air duct again and getting scalded.
在夏季，當輸送氣體的溫度低于周圍環境的空氣露點溫度時，通風管道外壁會產生冷凝現象。空調系統的空氣管道會增加冷卻損失，冷凝水滴會污染天花板和墻壁地板。因此，還應進行冷卻和隔熱處理。
In summer, when the temperature of the transported gas is lower than the ambient air dew point temperature, condensation will occur on the outer wall of the ventilation pipe. The air duct of the central air conditioning system will increase the cooling loss, and the condensate droplets will pollute the ceiling and wall floor. Therefore, cooling and heat insulation should also be carried out.
以上是通風管道防腐保溫的原因。只有防腐才能減少后期使用中的腐蝕，所以我們應該注意這些方面，并盡量保證在以后使用時更光滑，效果更好。您有什么問題就來我們網站

These are the reasons for corrosion prevention and insulation of ventilation pipes. Only corrosion prevention can reduce the corrosion in later use, so we should pay attention to these aspects and try to ensure that they are smoother and better in future use.
