通常使用(yong)鍍鋅風(feng)(feng)(feng)管(guan)，不銹鋼管(guan)用(yong)于腐蝕性和(he)特別潮濕(shi)的地方(fang)。當(dang)環境空氣濕(shi)度(du)較高時，風(feng)(feng)(feng)道(dao)外(wai)(wai)壁(bi)應(ying)進(jin)(jin)行(xing)(xing)防腐防銹處理(li)。輸送(song)高溫(wen)高濕(shi)的風(feng)(feng)(feng)道(dao)內(nei)壁(bi)應(ying)噴(pen)涂磷化(hua)底漆(qi)或其他防腐涂料。當(dang)風(feng)(feng)(feng)道(dao)輸送(song)高溫(wen)氣體或低溫(wen)空氣時，風(feng)(feng)(feng)道(dao)外(wai)(wai)壁(bi)應(ying)進(jin)(jin)行(xing)(xing)保溫(wen)（冷保）處理(li)。

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).

輸送高(gao)(gao)溫(wen)(wen)氣(qi)體(ti)的(de)(de)風道(dao)的(de)(de)隔(ge)熱(re)目的(de)(de)是防(fang)(fang)止(zhi)(zhi)管(guan)(guan)道(dao)中空(kong)(kong)氣(qi)的(de)(de)熱(re)量損失（冬季出現在(zai)集中式空(kong)(kong)調系統中）。在(zai)輸送廢熱(re)蒸汽(qi)或高(gao)(gao)溫(wen)(wen)氣(qi)體(ti)時，為(wei)了防(fang)(fang)止(zhi)(zhi)熱(re)量傳遞到室(shi)內并使室(shi)溫(wen)(wen)升高(gao)(gao)，可以防(fang)(fang)止(zhi)(zhi)人再次接觸風管(guan)(guan)并燙傷。在(zai)夏(xia)季，當輸送氣(qi)體(ti)的(de)(de)溫(wen)(wen)度(du)低于周圍(wei)環(huan)境(jing)的(de)(de)空(kong)(kong)氣(qi)露點溫(wen)(wen)度(du)時，通風管(guan)(guan)道(dao)外壁會(hui)產生冷(leng)凝(ning)現象。空(kong)(kong)調系統的(de)(de)空(kong)(kong)氣(qi)管(guan)(guan)道(dao)會(hui)增加冷(leng)卻(que)損失，冷(leng)凝(ning)水滴(di)會(hui)污染天花(hua)板和墻(qiang)壁地板。因此，還應進行(xing)冷(leng)卻(que)和隔(ge)熱(re)處理。

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(shi)通風管道防腐保溫的原因。只(zhi)有(you)防腐才(cai)能減少后期(qi)使(shi)用中(zhong)的腐蝕，所以我們應(ying)該注意(yi)這些方面(mian)，并(bing)盡量(liang)保證在(zai)以后使(shi)用時更(geng)光(guang)滑，效果更(geng)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.
