随着时间的推移，人们对清洗通风管道、节省设备和材料的要求逐渐提高;随着科技的进步，人们对暖通空调工程质量的要求也越来越高。许多现有的不锈钢风管和螺旋圆形风管用于满足通风、空调和除尘输送的功能要求。
With the passage of time, people's requirements for cleaning ventilation pipes and saving equipment and materials have gradually increased; With the progress of science and technology, people have higher and higher requirements for the quality of HVAC engineering. Many existing stainless steel air ducts and spiral circular air ducts are used to meet the functional requirements of ventilation, air conditioning and dust removal transportation.

这就需要在现有技术上不断进步，在装备规划、开发和制造方面采取更加经济、健康和可持续的发展战略。目前空调通风工程中使用的金属风管主要有圆形风管和不锈钢风管。圆形风管强度高，耗材少，但加工工艺杂乱，占用空间大；不锈钢风管易于组织和加工，应用广泛。也有用机器制造的。螺旋形状由钢带、圆带和矩形带制成。为了节省空间，很多不锈钢风管都是用扁圆做成的。
This requires continuous progress in existing technology and a more economic, healthy and sustainable development strategy in equipment planning, development and manufacturing. At present, the metal air ducts used in air conditioning and ventilation projects mainly include circular air ducts and stainless steel air ducts. The circular air duct has high strength and less consumables, but the processing technology is messy and takes up a large space; Stainless steel air duct is easy to organize and process and is widely used. It can also be made by machines. The spiral shape is made of steel strip, round belt and rectangular belt. In order to save space, many stainless steel air ducts are made of flat circles.
通风管道制造加工，尤其是一些小企业、手工作坊式企业，这些企业是撑不下去的。因为我们相信一个企业的发展离不开企业文化和战略的发展。主风道虽然仍采用铁板制作，但由于、使用寿命、防潮、隔音、承重等原因，在施工和防护方面存在诸多缺陷。这导致市场需要新产品来改掉这个问题。新型不锈钢风管的出现刚刚适应了购物广场的需求。经过多次应用和工程实践，投资者逐渐接受。
Ventilation duct manufacturing and processing, especially some small enterprises and manual workshop enterprises, these enterprises can not sustain. Because we believe that the development of an enterprise is inseparable from the development of corporate culture and brand strategy. Although the main air duct is still made of iron plate, there are many defects in construction and protection due to environmental protection, service life, moisture-proof, sound insulation, load-bearing and other reasons. This leads to the need for new products to overcome this problem. The emergence of new stainless steel air ducts has just adapted to the needs of shopping malls. After many applications and engineering practice, investors gradually accept it.
风管一般分为三类：镀锌不锈钢风管、不锈钢风管、复合不锈钢风管。同时，不锈钢风管质量好，适用性强，但昂贵。目前，使用广泛的不锈钢风管是镀锌钢管。镀锌不锈钢风管基本上是不锈钢风管的特点，但其比不锈钢风管低三分之二甚更低。不锈钢复合风管一般用于外部环境比较一般，对风管要求不太高的地方。由于铁皮简单，在各种环境中都会发生化学反应，导致腐蚀和生锈。然而，锌在干燥空气中几乎不变化。在潮湿空气中，锌表面会形成良好的碱性碳酸锌膜。不锈钢风管主要是在风管的铁皮上涂上一层锌，起到保护铁皮的作用。一旦镀锌层钝化、染色或涂上光刻胶，其保护和装饰性能就会得到显着改变。
Air ducts in shopping malls are generally divided into three categories: galvanized stainless steel air ducts, stainless steel air ducts and composite stainless steel air ducts. At the same time, the stainless steel air duct has good quality and strong applicability, but the price is expensive. At present, the widely used stainless steel air duct in shopping malls is galvanized steel pipe. Galvanized stainless steel air duct is basically the characteristic of stainless steel air duct, but its price is two-thirds or even lower than that of stainless steel air duct. Stainless steel composite air duct is generally used in places with general external environment and low requirements for air duct. Because the iron sheet is simple, chemical reactions will occur in various environments, resulting in corrosion and rust. However, zinc hardly changes in dry air. In humid air, a good alkaline zinc carbonate film will be formed on the zinc surface. Stainless steel air duct is mainly coated with a layer of zinc on the iron sheet of the air duct to protect the iron sheet. Once the zinc coating is passivated, dyed or coated with photoresist, its protective and decorative properties will be significantly changed.
通风管道的耐用性较差。氯化镁与氧化镁的摩尔比是有科学依据的。氯化镁含量应根据氧化镁中镁含量的测定来确定。然而，不合格产品的制造商并不知道氧化镁的镁含量的测定，更不用说合理的摩尔比值。只知道氧化镁和盐水会在气管中凝固。风管残留氯离子含量高，在潮湿空气环境中易返卤，使用寿命短。
The durability of ventilation ducts is poor. The molar ratio of magnesium chloride to magnesium oxide has a scientific basis. The content of magnesium chloride shall be determined according to the determination of magnesium content in magnesium oxide. However, manufacturers of unqualified products do not know the determination of magnesium content of magnesium oxide, let alone a reasonable molar ratio. All I know is that magnesium oxide and salt water solidify in the trachea. The residual chloride ion content of air duct is high, which is easy to return halogen in humid air environment and has short service life.
