盡管現(xiàn)在核心仍然是白鐵皮這一類的風管，但由于這種風管環(huán)境保護、壽限、防水、隔音降噪、載重等諸多方面的原因，在工程施工和維護方面存在許多缺點。這種情況導致了大型需要一種新的商品來改善這一難題，新型的不銹鋼風管展現(xiàn)出來，恰巧習慣了大型的需求，在根據(jù)許多工程項目應用及實踐經(jīng)驗后，逐漸由投資人房地產(chǎn)商承擔。

Although the core is still the air duct such as white iron sheet, there are many shortcomings in project construction and maintenance due to many reasons such as environmental protection, life limit, waterproof, sound insulation and noise reduction, load and so on. This situation leads to the need for a new commodity in large shopping malls to improve this problem. The new stainless steel air duct is displayed, which happens to be used to the needs of large shopping malls. After many engineering project applications and practical experience, it is gradually borne by investors and real estate developers.

在大型的風管上，根據(jù)材質(zhì)一般分為三類：熱鍍鋅不銹鋼風管、不銹鋼板不銹鋼風管及復合不銹鋼風管。它們中不銹鋼風管質(zhì)量好，適用范圍廣，但較高。

In large air duct shopping malls, they are generally divided into three categories according to the material: hot-dip galvanized stainless steel air duct, stainless steel plate stainless steel air duct and composite stainless steel air duct. Among them, stainless steel air ducts have good quality and wide application range, but the price is high.

現(xiàn)在大型中常用的不銹鋼風管都是鍍鋅鋼板。鍍鋅板不銹鋼風管，基礎(chǔ)是不銹鋼板不銹鋼風管的特點，但相對性要是不銹鋼管的三分之二甚更低。復合式不銹鋼風管一般應用于外界環(huán)境較一般、風管要求較低的場所。

Now the stainless steel air ducts commonly used in large shopping malls are galvanized steel. Galvanized stainless steel air duct is based on the characteristics of stainless steel air duct, but the price relativity is two-thirds or even lower than that of stainless steel pipe. Composite stainless steel air duct is generally used in places with general external environment and low air duct requirements.

因為白鐵皮在各種自然環(huán)境中很容易發(fā)生化學變化，導致浸蝕、銹蝕。山東的通風管道和鋅在干燥空氣中幾乎不產(chǎn)生變化。鋅的表面層在濕冷的空氣中形成了堿式碳酸鋅薄膜。不銹鋼管的關(guān)鍵是在風管白鐵表面鑲上一層鋅，對白鐵外殼起到了實際維護作用。鋅鍍層經(jīng)過不銹鋼鈍化、涂色或涂覆等處理，可顯著提高涂層的防護能力和裝飾藝術(shù)。

Because the white iron sheet is prone to chemical changes in various natural environments, resulting in corrosion and corrosion. Ventilation ducts and zinc in Shandong hardly change in dry air. The surface layer of zinc forms a basic zinc carbonate film in wet and cold air. The key of stainless steel pipe is to inlay a layer of zinc on the white iron surface of air pipe, which plays a practical role in maintaining the white iron shell. After passivation, coloring or coating of stainless steel, the protective ability and decorative art of zinc coating can be significantly improved.

(1)通風管道輸送氣體無噪音，或兼有消音作用

(1) The gas conveyed by the ventilation pipe has no noise or has silencing effect

(2)通風管道在耐壓允許標準下，風管內(nèi)氣體不易外泄，或氣管外氣不易內(nèi)侵入

(2) Under the allowable pressure resistance standard of ventilation pipe, the gas in the air pipe is not easy to leak out, or the gas outside the gas pipe is not easy to invade

(3)通風管道應用期限短維修簡便。

(3) The ventilation pipe has short application life and easy maintenance.
