廚房排煙管道對整個廚房排風系統的重要性不言而喻。那么，作為如此重要的部件，廚房排煙管道的材質應該如何選擇呢？

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?

目前廚房廚房排煙管道常用的材料有不銹鋼板和鍍鋅鋼板。鍍鋅鋼通過在鋼表面涂上一層金屬鋅來防止生銹。由于鋅的化學活性比鐵高，鋅往往在鐵之前氧化，從而保護鐵層免受損壞。

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.

不銹鋼與鉻形成合金，在其表面形成一層非常薄、強度高且非常穩定的富鉻氧化膜。這種緊密附著的富鉻氧化物保護了表面，可以有效地阻止氧原子的繼續滲透和氧化，從而產生耐腐蝕性。應該說兩者都具有良好的防銹性。

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，還是建議大家選擇不銹鋼板，為什么呢？它從煙灰的成分開始。油煙的成分非常復雜，與燃料種類、食用油種類、配料、烹調時間、烹調溫度、烹調方法等諸多因素有關。

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.

不同種類的食用油在高溫下有多種熱解產物，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。有的產品會與水結合形成亞硝酸、硝酸、碳酸等腐蝕性物質，在通過廚房排煙管道時必然會對廚房排煙管道造成腐蝕。因此，廚房排煙管道的材質除了防銹外，還應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.

在這方面，不銹鋼比鍍鋅鋼強。濟南廚房排煙廠家在此以304不銹鋼為例，也就是18/8不銹鋼。其標準成分為18%鉻加8%鎳。據介紹，這類鋼在空氣中的年腐蝕率一般小于0.01毫米。即使在廚房油煙較多的環境中，年腐蝕率也往往小于0.02毫米，可見其耐腐蝕性。此外，不銹鋼板還具有良好的隔熱性和耐熱性。

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.
