廚房消防排煙管道應該用什么材質?

油煙凈化系統由風機、集煙罩、排煙管道和油煙凈化器組成。消防排煙管道對整個廚房排煙系統的重要性是顯而易見的。那么,作為如此重要的構件,消防排煙管道材料應該如何選擇呢?
The oil fume purification system is composed of fan, smoke collecting hood, smoke exhaust pipe and oil fume purifier. The importance of fire smoke exhaust pipe to the whole kitchen smoke exhaust system is obvious. So, as such an important component, how to choose the material of fire smoke exhaust pipe?
目前廚房排煙管道常用的材料有不銹鋼板和鍍鋅鋼板。消防排煙管道鍍鋅鋼板通過在鋼板表面涂上一層金屬鋅來防銹。因為鋅的化學性比鐵高,鋅往往比鐵先氧化,從而保護鐵層免受損壞。不銹鋼與鉻形成合金,并在其表面形成非常薄、牢固和精細穩定的富鉻氧化膜。這種緊密附著的富鉻氧化物保護了表面,可以防止氧原子繼續氧化,從而獲得耐腐蝕性。應該說兩者都有很好的防銹能力。
At present, the commonly used materials of kitchen smoke exhaust pipes are stainless steel plate and galvanized steel plate. A layer of zinc is coated on the surface of the smoke exhaust pipe through the galvanized steel plate. Because zinc is more chemical than iron, zinc often oxidizes before iron, so as to protect the iron layer from damage. Stainless steel is alloyed with chromium and forms a very thin, firm, fine and stable chromium rich oxide film on its surface. This closely attached chromium rich oxide protects the surface and can prevent the continuous oxidation of oxygen atoms, so as to obtain corrosion resistance. It should be said that both have good anti rust ability.
相比之下,建議你選擇不銹鋼板,那么為什么呢?這要從油煙的成分說起。油煙的成分非常復雜,與燃料種類、食用油種類、配料、烹飪時間、烹飪溫度、烹飪方法等諸多因素有關。
In contrast, I suggest you choose stainless steel plate, so why? This should start with the composition of oil fume. The composition of oil fume is very complex, which is related to many factors, such as fuel type, edible oil type, ingredients, cooking time, cooking temperature, cooking method and so on.
不同種類的食用油在高溫下有200多種熱解產物,包括烴類、醛類、酮類、醇類、烴類、脂肪酸類、芳香族化合物和雜環化合物等。有些產品會與水相結合形成亞硝酸、硝酸、碳酸等腐蝕性物質,經過排煙管道時不可避免地會對排煙管道造成腐蝕。因此,除了防銹外,排煙管道的材質也要有一定程度的耐弱酸性。
There are more than 200 pyrolysis products of different kinds of edible oil at high temperature, including hydrocarbons, aldehydes, ketones, alcohols, hydrocarbons, fatty acids, aromatic compounds and heterocyclic compounds. Some products will combine with water to form corrosive substances such as nitrite, nitric acid and carbonic acid, which will inevitably corrode the smoke exhaust pipe when passing through the smoke exhaust pipe. Therefore, in addition to rust prevention, the material of smoke exhaust pipe should also have a certain degree of weak acid resistance.
