不锈钢风管的洁净要求!
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.

不锈钢风管别是一些小企业、手工作坊式的企业,这样的企业生存力不会长久。因为坚信一个企业要发展,是与其的企业文化和品牌战略的发展离不开的。虽然目前主导的仍是铁皮这一类的风管,但由于这些风管环保、寿命、防潮、隔音、承重等各方面原因,在施工和维护上存在许多的缺陷。这就导致了市场需要一种新的产品来改善这一难题,新型不锈钢风管的出现,正好适应了市场的需求,在通过大量工程应用及实践证明后,逐渐的被投资方开发商所接受。
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.
 
不锈钢风管市场上按材质一般分为三类:镀锌不锈钢风管、不锈钢不锈钢风管以及复合不锈钢风管。其中,不锈钢风管质量较好,适用性强,但价格高。目前市场上较广的不锈钢风管是镀锌板的。镀锌板不锈钢风管,基本是不锈钢不锈钢风管的特性,但是价格相对只有不锈钢风管的三分之二甚至更低。复合不锈钢风管一般应用在外界环境较为普通,对风管要求不太高的场所。由于铁皮容易在各种环境下发生化学反应,造成腐蚀、生锈。而锌在干燥的空气中几乎不发生变化。在潮湿的空气中,锌表面会生成致密的碱式碳酸锌膜。不锈钢风管主要是在风管铁皮上镀上一层锌,对铁皮起到保护的作用。锌镀层经钝化处理、染色或涂覆护光剂后,能显著提高其防护性和装饰性。
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。
不锈钢风管耐久性差氯化镁和氧化镁克分子量配比是有科学依据的,是要根据氧化镁的活性镁含量的测定来确定氯化镁的用量。但是不合格产品生产企业不知道氧化镁活性含镁量的测定,更不知道摩尔比的合理值。只知道氧化镁加卤水,固化后成风管。其风管剩余氯离子含量大,遇上潮湿的空气环境易返卤,软化系数低,使用寿命短。
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。
