隨著時間的推移，人們對通風(fēng)管道的清洗要求和對設(shè)備材料的節(jié)約要求也逐漸提高;隨著技術(shù)的進步，人們對暖通空調(diào)工程質(zhì)量的要求也相應(yīng)提高?，F(xiàn)有的不銹鋼風(fēng)管和螺旋風(fēng)管被廣泛應(yīng)用于滿足通風(fēng)、空調(diào)和除塵的功能要求。
With the passage of time, people's requirements for cleaning of ventilation pipes and saving of equipment and materials are gradually improved; with the progress of technology, people's requirements for the quality of HVAC engineering are also correspondingly improved. The existing stainless steel air duct and spiral air duct are widely used to meet the functional requirements of ventilation, air conditioning and dust removal.
這就要求在現(xiàn)有技術(shù)不斷進步的同時，采用更多的節(jié)材、健康、可持續(xù)的發(fā)展戰(zhàn)略進行設(shè)備的設(shè)計、開發(fā)和制造。目前，空調(diào)通風(fēng)工程中金屬風(fēng)管的主要形式有:圓形風(fēng)管、不銹鋼風(fēng)管。圓管強度消耗小，但加工工藝復(fù)雜，占用空間大。不銹鋼風(fēng)管易于布置，易于加工，所以使用比較普遍。也有機械制作的由鋼帶螺旋纏繞而成的系統(tǒng)，圓形、長方形，為了節(jié)省空間，大量的不銹鋼風(fēng)管做成扁平狀。
This requires more material saving, healthy and sustainable development strategies to design, develop and manufacture the equipment while the existing technology is constantly improving. At present, the main forms of metal air duct in air conditioning and ventilation engineering are: round air duct and stainless steel air duct. The strength consumption of the pipe is small, but the processing technology is complex and takes up a lot of space. Stainless steel air duct is easy to arrange and process, so it is widely used. There are also mechanical systems made of spiral wound steel strips, circular and rectangular. In order to save space, a large number of stainless steel air ducts are made into flat shapes.
通風(fēng)管道的生產(chǎn)加工，特別是對一些小型企業(yè)、手工工坊型企業(yè)來說，這樣的企業(yè)生存不了多久。因為企業(yè)認為企業(yè)的發(fā)展離不開企業(yè)文化和戰(zhàn)略。雖然目前占主導(dǎo)地位的仍是鐵皮這種風(fēng)管，但由于這些風(fēng)管環(huán)保、壽命、防潮、隔音、承重等方面的原因，在施工和維護中存在許多缺陷。這導(dǎo)致了市場需要一款新產(chǎn)品來改善這一問題，新型不銹鋼風(fēng)管的出現(xiàn)，正好適應(yīng)了市場的需求，通過大量的工程應(yīng)用和實踐，逐漸被投資開發(fā)商所接受。
The production and processing of ventilation pipes, especially for some small enterprises and manual workshop enterprises, such enterprises will not survive for long. Because enterprises think that the development of enterprises can not be separated from corporate culture and brand strategy. Although the iron sheet air duct is still dominant at present, there are many defects in construction and maintenance due to the environmental protection, service life, moisture-proof, sound insulation, load-bearing and other reasons of these air ducts. This leads to the market need for a new product to improve this problem, the emergence of new stainless steel air duct, just to meet the market demand, through a large number of engineering applications and practices, gradually accepted by the investment developers.
風(fēng)管市場按材質(zhì)一般分為三類:鍍鋅不銹鋼風(fēng)管、不銹鋼風(fēng)管和復(fù)合不銹鋼風(fēng)管。其中，不銹鋼風(fēng)管質(zhì)量較好，適用性強，但價格較高。目前，市場上比較廣泛的是鍍鋅不銹鋼風(fēng)管。鍍鋅不銹鋼風(fēng)管，基本上是不銹鋼風(fēng)管的特點，但價格相對只有不銹鋼風(fēng)管的三分之二甚至更低。復(fù)合不銹鋼風(fēng)管一般多用于外部環(huán)境比較常見，對風(fēng)管要求不太高。由于鐵板在各種環(huán)境中容易產(chǎn)生化學(xué)反應(yīng)，引起腐蝕、生銹。另一方面，鋅在干燥的空氣中變化不大。在潮濕的空氣中，鋅表面會形成一層致密的堿性碳酸鋅膜。不銹鋼風(fēng)管主要是在風(fēng)管鐵板上涂一層鋅，以保護鐵板。鍍鋅層經(jīng)鈍化、染色或涂上防護光劑后，可顯著提高其防護性和裝飾性。
The air duct market is generally divided into three categories by material: galvanized stainless steel air duct, stainless steel air duct and composite stainless steel air duct. Among them, the quality of stainless steel air duct is good, applicability is strong, but the price is high. At present, galvanized stainless steel air ducts are widely used in the market. Galvanized stainless steel air duct is basically the characteristics of stainless steel air duct, but the price is only two-thirds or even lower than that of stainless steel air duct. The composite stainless steel air duct is usually used in the external environment, so the requirement of air duct is not very high. Because the iron plate is easy to produce chemical reaction in various environments, causing corrosion and rust. Zinc, on the other hand, does not change much in dry air. In humid air, a dense alkaline zinc carbonate film is formed on the surface of zinc. The stainless steel air duct is mainly coated with a layer of zinc on the iron plate of the air duct to protect the iron plate. After passivation, dyeing or coating with protective light agent, the protective and decorative properties of zinc coating can be significantly improved.
通風(fēng)管道耐久性差氯化鎂與氧化鎂克分子量比的依據(jù)是科學(xué)依據(jù)，是確定活性鎂含量的氧化鎂氯化鎂的用量。但是，生產(chǎn)不合格產(chǎn)品的廠家不知道氧化鎂活度的測定方法和合理的摩爾比值。只知道氧化鎂加鹵水，固化成管后。風(fēng)管殘余氯離子含量大，在潮濕空氣環(huán)境中容易返鹵，軟化系數(shù)低，使用壽命短。
The basis of the ratio of MgCl 2 to MgO is scientific basis, which is to determine the amount of MgCl 2 with active MgO content. However, the manufacturers of unqualified products do not know the determination method of MgO activity and the reasonable molar ratio. Only magnesium oxide with brine, solidified into a tube. The residual chloride ion content of air duct is large, and it is easy to return brine in humid air environment, with low softening coefficient and short service life.
