管道風機在很多行業(yè)有著廣泛的應用，通風管道應用廣泛的原因跟他的特點是分不開的螺旋廠房通風管道市場上按材質一般分為三類：鍍鋅螺旋風管、不銹鋼螺旋風管以及復合螺旋風管。其中，不銹鋼風管質量，適用性強，但價格高。目前市場通廣的螺旋風管是鍍鋅板的。鍍鋅板螺旋風管，基本是不銹鋼螺旋風管的特性，但是價格相對只有不銹鋼風管的三分之二甚至更低。復合螺旋風管一般應用在外界環(huán)境較為普通，對風管要求不太高的場所。由于鐵皮容易在各種環(huán)境下發(fā)生化學反應，造成腐蝕、生銹。而鋅在干燥的空氣中幾乎不發(fā)生變化。在潮濕的空氣中，鋅表面會生成致密的堿式碳酸鋅膜。螺旋風管主要是在風管鐵皮上鍍上一層鋅，對鐵皮起到保護的作用。鋅鍍層經鈍化處理、染色或涂覆護光劑后，能顯著提高其防護性和裝飾性。

Pipeline fans are widely used in many industries, and the reason for the widespread use of ventilation ducts is closely related to their characteristics. In the spiral factory ventilation duct market, they are generally divided into three categories based on material: galvanized spiral duct, stainless steel spiral duct, and composite spiral duct. Among them, stainless steel air ducts are of high quality and applicability, but their prices are high. At present, the widely circulated spiral air duct in the market is made of galvanized sheet. Galvanized sheet spiral air duct is basically a characteristic of stainless steel spiral air duct, but its price is relatively only two-thirds or even lower than that of stainless steel air duct. Composite spiral air ducts are generally used in places with ordinary external environments and low requirements for air ducts. Due to the susceptibility of iron sheet to chemical reactions in various environments, it can cause corrosion and rusting. And zinc hardly changes in dry air. In humid air, dense basic Zinc carbonate film will be formed on the surface of zinc. The spiral air duct is mainly coated with a layer of zinc on the iron sheet of the air duct, which plays a protective role on the iron sheet. The zinc coating can significantly improve its protective and decorative properties after passivation treatment, dyeing, or coating with protective agents.

通風管道不銹鋼風管特點介紹：

Introduction to the characteristics of stainless steel air ducts in ventilation ducts:

1、外形美觀、內壁光滑、阻力小、氣密性好、承壓強度高，能適合非常復雜的排氣工程

1. Beautiful appearance, smooth inner wall, low resistance, good airtightness, high compressive strength, suitable for very complex exhaust engineering

2、可排除可燃及不可燃之化學腐蝕氣體，而不需要另外裝置灑水滅火設備。

2. It can eliminate flammable and non combustible chemical corrosive gases without the need for additional sprinkler fire extinguishing equipment.

3、由不銹鋼制成，材質堅固，易保持完整性。。

3. Made of stainless steel, the material is sturdy and easy to maintain integrity..

目前市場通廣的螺旋風管是鍍鋅板的螺旋廠房通風管道螺旋咬縫薄壁管，早是瑞士發(fā)明的螺旋風管，螺旋風管應用于西方國家的軍工業(yè)，如軍艦、輪船排（送）風系統(tǒng)，后來用于火車、地鐵、礦山等民用設施。螺旋廠房通風管道在一些外資、合資企業(yè)中率先使用。、由于螺旋風管有骨（螺旋形咬縫）可提高強度30%，故可選用較薄的材料，比如0.8毫米的厚度可改為0.6毫米，另外在同樣截面積的情況下，采用螺旋風管可節(jié)省材料20%。由于鐵皮容易在各種環(huán)境下發(fā)生化學反應，造成腐蝕、生銹。而鋅在干燥的空氣中幾乎不發(fā)生變化。在潮濕的空氣中，鋅表面會生成致密的堿式碳酸鋅膜。螺旋風管主要是在風管鐵皮上鍍上一層鋅，對鐵皮起到保護的作用。鋅鍍層經鈍化處理、染色或涂覆護光劑后，能顯著提高其防護性和裝飾性。。

At present, the widely circulated spiral air duct in the market is a galvanized sheet spiral factory ventilation duct with spiral seam thin-walled pipes, which was invented by Switzerland. Spiral air ducts were first applied to military industries in Western countries, such as warships and ship exhaust (supply) air systems, and later used in civilian facilities such as trains, subways, and mines. Spiral factory ventilation ducts were first used in some foreign and joint venture enterprises Due to the fact that the spiral duct has a bone (spiral seam) that can increase its strength by 30%, thinner materials can be selected, such as a thickness of 0.8 millimeters that can be changed to 0.6 millimeters. In addition, using spiral ducts can save 20% of the material under the same cross-sectional area. Due to the susceptibility of iron sheet to chemical reactions in various environments, it can cause corrosion and rusting. And zinc hardly changes in dry air. In humid air, dense basic Zinc carbonate film will be formed on the surface of zinc. The spiral air duct is mainly coated with a layer of zinc on the iron sheet of the air duct, which plays a protective role on the iron sheet. The zinc coating can significantly improve its protective and decorative properties after passivation treatment, dyeing, or coating with protective agents..
