油烟净化系统由风机、集烟罩、排烟管道和油烟净化器组成。消防排烟管道对整个厨房排烟系统的重要性是显而易见的。那么,作为如此重要的构件,消防排烟管道材料应该如何选择呢?
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?
目前厨房排烟管道常用的材料有不锈钢板和镀锌钢板。消防排烟管道镀锌钢板通过在钢板表面涂上一层金属锌来防锈。因为锌的化学性比铁高,锌往往比铁先氧化,从而保护铁层免受损坏。不锈钢与铬形成合金,并在其表面形成非常薄、牢固和精细稳定的富铬氧化膜。这种紧密附着的富铬氧化物保护了表面,可以防止氧原子继续氧化,从而获得耐腐蚀性。应该说两者都有很好的防锈能力。
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,建议你选择不锈钢板,那么为什么呢?这要从油烟的成分说起。油烟的成分非常复杂,与燃料种类、食用油种类、配料、烹饪时间、烹饪温度、烹饪方法等诸多因素有关。
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.
不同种类的食用油在高温下有200多种热解产物,包括烃类、醛类、酮类、醇类、烃类、脂肪酸类、芳香族化合物和杂环化合物等。有些产品会与水相结合形成亚硝酸、硝酸、碳酸等腐蚀性物质,经过排烟管道时不可避免地会对排烟管道造成腐蚀。因此,除了防锈外,排烟管道的材质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.
