随着时间的推移,人们对不锈钢风管的洁净要求和设备材料的节约要求也逐步提高。随着技术进步,人们对暖通空 调工程品质要求相应提高,现有的不锈钢风管及螺旋圆风管大量使用,满足了通风空调及除尘输送的功能要求。这就要求在现有的技术上进行不断的进步,采用更加节省材料,健康的可持续发展的策略进行设备的设计开发 与制造。目前空调通风工程上应用的金属风管形式主要有：圆形风管,不锈钢风管。圆形风管强度大耗材少,但加工工 艺复杂些,占用空间大；不锈钢风管易布置,容易加工,因而使用较为普遍。还有系机械化生产由钢带螺旋绕 制而成,有圆形、矩形,为节省空间,大量的不锈钢风管做成扁圆形。不锈钢风管厂家
With the passage of time, people's requirements for cleanliness of stainless steel air ducts and saving of equipment materials have gradually increased. With the development of technology, the quality requirement of HVAC project has been improved accordingly. The existing stainless steel air ducts and spiral round air ducts have been widely used to meet the functional requirements of ventilation, air conditioning and dust removal. This requires continuous progress in the existing technology, the use of more material-saving, healthy and sustainable development strategy for equipment design, development and manufacturing. At present, the main types of metal air ducts used in air conditioning and ventilation engineering are circular air ducts and stainless steel air ducts. Round air duct has high strength and less consumables, but its processing technology is complex and occupies large space. Stainless steel air duct is easy to arrange and process, so it is widely used. In addition, the mechanical production is made of steel strip spirally wound, with circular and rectangular, in order to save space, a large number of stainless steel air ducts are made into flat circular.

Stainless steel air ducts are small enterprises and manual workshop-like enterprises, so the viability of such enterprises will not last long. Because we firmly believe that the development of an enterprise is inseparable from the development of its corporate culture and brand strategy. Although the current dominant type of air duct is still iron sheet, there are many defects in construction and maintenance due to the environmental protection, life, moisture-proof, sound insulation, load-bearing and other reasons of these air ducts. This has led to the market need for a new product to improve this problem, the emergence of new stainless steel ducts, just in line with the market demand, after a large number of engineering applications and practical proof, gradually accepted by investors developers.
The stainless steel air duct market is generally divided into three categories according to the material: galvanized stainless steel air duct, stainless steel air duct and composite stainless steel air duct。 Among them, stainless steel air duct is of good quality and good applicability, but its price is high。 At present, galvanized sheet is widely used in stainless steel air ducts on the market。 Galvanized stainless steel ducts are basically stainless steel ducts, but the price is only two-thirds or even lower than that of stainless steel ducts。 Composite stainless steel ducts are generally used in places where the external environment is relatively common and the requirements for ducts are not very high。 Because iron sheet is easy to react in various environments, it causes corrosion and rust。 Zinc hardly changes in dry air。 In moist air, a dense alkaline zinc carbonate film is formed on the surface of zinc。 Stainless steel air duct is mainly coated with zinc on the iron sheet of the air duct, which plays a protective role on the iron sheet。 The protective and decorative properties of zinc coatings can be significantly improved by passivation, dyeing or coating with light protector。
The molecule weight ratio of magnesium chloride and magnesium oxide in stainless steel ducts with poor durability is based on scientific basis。 The amount of magnesium chloride should be determined according to the determination of active magnesium content of magnesium oxide。 But the manufacturer of unqualified products does not know the determination of active magnesium content of magnesium oxide, let alone the reasonable value of molar ratio。 Only know magnesium oxide plus brine, solidified air duct。 The residual chloride ion content of the air duct is large, and it is easy to return halogen in humid air environment, with low softening coefficient and short service life。
