管道風(fēng)機在很多行業(yè)有著廣泛的應(yīng)用，通風(fēng)管道應(yīng)用廣泛的原因跟他的特點是分不開的螺旋廠房通風(fēng)管道市場上按材質(zhì)一般分為三類：鍍鋅螺旋風(fēng)管、不銹鋼螺旋風(fēng)管以及復(fù)合螺旋風(fēng)管。其中，不銹鋼風(fēng)管質(zhì)量，適用性強，但高。目前市場通廣的螺旋風(fēng)管是鍍鋅板的。鍍鋅板螺旋風(fēng)管，基本是不銹鋼螺旋風(fēng)管的特性，但是相對只有不銹鋼風(fēng)管的三分之二甚更低。復(fù)合螺旋風(fēng)管一般應(yīng)用在外界環(huán)境較為普通，對風(fēng)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(xué)反應(yīng)，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(fēng)管主要是在風(fēng)管鐵皮上鍍上一層鋅，對鐵皮起到保護的作用。鋅鍍層經(jīng)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(fēng)管道不銹鋼風(fēng)管特點介紹：

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

1、外形美觀、內(nèi)壁光滑、阻力小、氣密性好、承壓強度高，能適合非常復(fù)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(xué)腐蝕氣體，而不需要另外裝置灑水滅火設(shè)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(zhì)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(fēng)管是鍍鋅板的螺旋廠房通風(fēng)管道螺旋咬縫薄壁管，早是瑞士發(fā)明的螺旋風(fēng)管，螺旋風(fēng)管應(yīng)用于西方的軍工業(yè)，如軍艦、輪船排（送）風(fēng)系統(tǒng)，后來用于火車、地鐵、礦山等民用設(shè)施。螺旋廠房通風(fēng)管道在一些外資、合資企業(yè)中率先使用。、由于螺旋風(fēng)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(fēng)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(xué)反應(yīng)，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(fēng)管主要是在風(fēng)管鐵皮上鍍上一層鋅，對鐵皮起到保護的作用。鋅鍍層經(jīng)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..
