Ventilation duct is a municipal infrastructure for air circulation and reducing the concentration of harmful gases, which is widely used in catering, hotels, industry and agriculture and other industries. In life, we can see ventilation ducts everywhere, and the importance of ventilation ducts is self-evident. Due to the high production cost of ventilation pipes, people pay more and more attention to the maintenance of pipes

冷熱絕緣

Cold and hot insulation

冬季(保溫):防止管道內(nèi)空氣的熱量流失;

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

輸送余熱蒸汽或高溫氣體時(shí)，熱量會(huì)散發(fā)到空間中，室內(nèi)溫度會(huì)升高;

When transporting waste heat steam or high-temperature gas, heat will be emitted into the space, and the indoor temperature will rise;

防止接觸風(fēng)管時(shí)燙傷;

Prevent scalding when contacting the air duct;

夏天(保冷):因?yàn)檫\(yùn)輸天然氣的溫度低于周圍環(huán)境的溫度,冷凝可能發(fā)生在管道的外壁,這將增加冷卻損失的空調(diào)系統(tǒng)的風(fēng)道,冷凝液滴會(huì)污染天花板和墻上,所以要做好冷保溫處理。

Summer (cold insulation): because the temperature of natural gas transported is lower than that of the surrounding environment, condensation may occur on the outer wall of the pipeline, which will increase the cooling loss of the air duct of the air conditioning system, and condensate droplets will pollute the ceiling and wall, so cold insulation treatment should be done well.

另外，風(fēng)管輸送氣體時(shí)，對(duì)風(fēng)管進(jìn)行除銹，刷防銹漆，對(duì)含塵氣體噴涂防損保護(hù)層。當(dāng)環(huán)境空氣濕度較大時(shí)，風(fēng)管外壁應(yīng)進(jìn)行防腐、防銹處理。只有防腐保溫(冷保溫)才能減少后期使用過(guò)程中的腐蝕現(xiàn)象。

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

如何防止腐蝕?

How to prevent corrosion?

俗話說(shuō)“三層內(nèi)三層外”，其實(shí)這不是開(kāi)玩笑!

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

噴涂防腐工藝真的需要面漆6次才能達(dá)到防腐!

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

綜上所述，只有進(jìn)行防腐、保溫、冷保溫，才能在以后的使用過(guò)程中減少腐蝕現(xiàn)象。

To sum up, only by carrying out anti-corrosion, thermal insulation and cold insulation can we reduce corrosion in the later use process.
