厨房排烟管道对整个厨房排风系统的重要性不言而喻。那么，作为如此重要的部件，厨房排烟管道的材质应该如何选择呢？
The importance of kitchen smoke exhaust pipe to the whole kitchen exhaust system is self-evident. So, as such an important component, how to choose the material of kitchen smoke exhaust pipe?
目前厨房厨房排烟管道常用的材料有不锈钢板和镀锌钢板。镀锌钢通过在钢表面涂上一层金属锌来防止生锈。由于锌的化学活性比铁高，锌往往在铁之前氧化，从而保护铁层免受损坏。
At present, the commonly used materials of kitchen smoke exhaust pipes are stainless steel plate and galvanized steel plate. Galvanized steel prevents rust by coating the steel surface with a layer of metallic zinc. Because zinc has higher chemical activity than iron, zinc often oxidizes before iron, so as to protect the iron layer from damage.
不锈钢与铬形成合金，在其表面形成一层非常薄、强度高且非常稳定的富铬氧化膜。这种紧密附着的富铬氧化物保护了表面，可以有效地阻止氧原子的继续渗透和氧化，从而产生耐腐蚀性。应该说两者都具有良好的防锈性。
Stainless steel is alloyed with chromium to form a very thin, high-strength and stable chromium rich oxide film on its surface. This closely attached chromium rich oxide protects the surface and can effectively prevent the continuous penetration and oxidation of oxygen atoms, resulting in corrosion resistance. It should be said that both have good rust resistance.
但是，相比之下，还是建议大家选择不锈钢板，为什么呢？它从烟灰的成分开始。油烟的成分非常复杂，与燃料种类、食用油种类、配料、烹调时间、烹调温度、烹调方法等诸多因素有关。
However, in contrast, it is recommended that you choose stainless steel plate. Why? It starts with the composition of soot. 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。有的产品会与水结合形成亚硝酸、硝酸、碳酸等腐蚀性物质，在通过厨房排烟管道时必然会对厨房排烟管道造成腐蚀。因此，厨房排烟管道的材质除了防锈外，还应具有一定的抗弱酸能力。
Different kinds of edible oils have a variety of pyrolysis products 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 cause corrosion to the kitchen smoke exhaust pipe when passing through the kitchen smoke exhaust pipe. Therefore, in addition to rust prevention, the material of kitchen smoke exhaust pipe should also have a certain ability to resist weak acid.
在这方面，不锈钢比镀锌钢强。
济南厨房排烟厂家在此以304不锈钢为例，也就是18/8不锈钢。其标准成分为18%铬加8%镍。据介绍，这类钢在空气中的年腐蚀率一般小于0.01毫米。即使在厨房油烟较多的环境中，年腐蚀率也往往小于0.02毫米，可见其耐腐蚀性。此外，不锈钢板还具有良好的隔热性和耐热性。
In this regard, stainless steel is stronger than galvanized steel. Jinan kitchen smoke exhaust manufacturer here takes 304 stainless steel as an example, that is, 18 / 8 stainless steel. Its standard composition is 18% chromium and 8% nickel. It is reported that the annual corrosion rate of this kind of steel in the air is generally less than 0.01 mm. Even in the environment with more oil fume in the kitchen, the annual corrosion rate is often less than 0.02 mm, which shows its corrosion resistance. In addition, the stainless steel plate also has good heat insulation and heat resistance.
Now, do you know what materials should be used for the smoke exhaust pipe of Jinan kitchen? The price of different materials is also different. It depends on your actual situation to choose the right one. For more information, please visit www.1nightescorts.com Com follow the consultation.
