通風管道是為了空氣流通、降低有害氣體濃度的一種市政基礎(chǔ)設施，廣泛應用于餐飲酒店和工農(nóng)業(yè)領(lǐng)域。在生活中我們處處都能看到通風管道，通風管道的重要性不言而喻。由于通風管道制作成本高，所以管道的保養(yǎng)處理問題日益受到重視，給通風管道制作和安裝使用的過程加個“保險”——做好防腐保溫工作就勢在必行。

Ventilation pipe is a kind of municipal infrastructure for air circulation and reducing the concentration of harmful gases, which is widely used in restaurants, hotels, industry and agriculture. We can see the ventilation duct everywhere in our life. The importance of the ventilation duct is self-evident. Due to the high production cost of ventilation pipes, the problem of pipe maintenance and treatment has been paid more and more attention. It is necessary to add "insurance" to the production and installation of ventilation pipes.

保溫和保冷：

Heat and cold preservation:

冬天（保熱）：防止管道內(nèi)空氣的熱損失；

Winter (heat preservation): prevent the heat loss of air in the pipeline;

防止在輸送廢熱蒸汽或高溫氣體時，熱量散發(fā)到空間內(nèi)而室內(nèi)溫度升高；

To prevent the heat from radiating into the space and the indoor temperature rising when the waste hot steam or high temperature gas is transported;

防止人接觸風道被燙傷；

Prevent people from being scalded by touching the air duct;

夏天（保冷）：可能出現(xiàn)因為輸送氣體的溫度低于周圍環(huán)境的溫度，管道外壁會產(chǎn)生結(jié)露現(xiàn)象，這對集中空調(diào)系統(tǒng)的風道會加大冷量損失，同時凝結(jié)水滴會污染吊頂和墻面，所以要做好保冷隔熱處理。

In summer (cold insulation): condensation may occur on the outer wall of the pipeline because the temperature of the delivered gas is lower than the temperature of the surrounding environment, which will increase the loss of cooling capacity on the air duct of the central air conditioning system, and at the same time, the condensate will pollute the ceiling and the wall, so it is necessary to do a good job of cold insulation.

另外，當風道輸送氣體時，對風道進行除銹、刷防銹漆處理，對含塵氣體可噴涂防損保護層。當周圍環(huán)境空氣濕度較大時，風道外壁需做防腐蝕、防銹處理。只有進行防腐保溫（保冷），才能在之后的使用過程中減少腐蝕的現(xiàn)象。

In addition, when the air duct is conveying gas, the air duct shall be derusted and painted with antirust paint, and the dust containing gas can be sprayed with a loss proof protective layer. When the ambient air humidity is high, the outer wall of air duct shall be treated with anti-corrosion and anti rust treatment. Only anticorrosion and heat preservation (cold insulation) can reduce the corrosion in the later use process.

如：在雨季施工的過程之中要控制環(huán)境的溫度，必須要使用溫度計進行檢測，如果空氣施工超標，那么在這種四氟噴涂材料之中應該加入催干劑，以防泛白的情況發(fā)生，這些都是在施工過程中需要注意問題，對人員的操作的一個風干的過程之中，一定要嚴格控制溫度以及濕度。

For example, in the process of construction in the rainy season, to control the temperature of the environment, a thermometer must be used for detection. If the air construction exceeds the standard, then a drier should be added to the tetrafluorocarbon spraying material to prevent the occurrence of whitening. These are problems to be noted in the construction process. In the process of air drying for the operation of professionals, it must be strictly controlled Temperature and humidity.

俗語常說“里三層外三層才”，其實這并不是一句玩笑話！

As the saying goes, "three layers inside and three layers outside are safe", in fact, this is not a joke!

噴涂防腐工藝的確需要面漆6次，才能真正做到防腐！

Spraying anti-corrosion process really needs 6 times of finish paint, in order to really achieve anti-corrosion!

綜上所述，只有進行防腐保溫保冷，才能在之后的使用過程中減少腐蝕的現(xiàn)象。

To sum up, only anticorrosion, heat preservation and cold insulation can reduce the corrosion in the later use process.
