隨著時(shí)間的推移，人們對(duì)通風(fēng)管道清洗的要求和對(duì)設(shè)備、材料的節(jié)約要求也在逐漸提高;隨著技術(shù)的進(jìn)步，人們對(duì)暖通工程質(zhì)量的要求也隨之提高。現(xiàn)有的許多不銹鋼風(fēng)管和螺旋圓風(fēng)管用于滿足通風(fēng)、空調(diào)和除塵輸送的功能要求。
With the passage of time, people's requirements for ventilation duct cleaning and the saving of equipment and materials are also gradually improving; With the progress of technology, people's requirements for the quality of HVAC engineering have also increased. Many existing stainless steel air ducts and spiral round air ducts are used to meet the functional requirements of ventilation, air conditioning and dust removal transportation.
這就需要在現(xiàn)有技術(shù)上不斷進(jìn)步，在設(shè)備規(guī)劃、開(kāi)發(fā)和制造方面采用更節(jié)約材料、更健康和更可持續(xù)的發(fā)展戰(zhàn)略。目前用于空調(diào)通風(fēng)工程的金屬風(fēng)道主要有圓形風(fēng)道和不銹鋼風(fēng)道。圓形風(fēng)管強(qiáng)度高，耗材少，但加工工藝較亂，占用空間大;不銹鋼風(fēng)道，便于布置和加工，應(yīng)用廣泛。也有機(jī)械生產(chǎn)的，螺旋形由鋼帶繞制而成，有圓形、長(zhǎng)方形，為了節(jié)省空間，許多不銹鋼風(fēng)管用平圓制成。
This requires continuous progress in existing technology and the adoption of more material-saving, healthier and more sustainable development strategies 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 lot of space; Stainless steel air duct, easy to arrange and process, is widely used. There are also mechanical ones. The spiral shape is made of steel strip. There are circular and rectangular shapes. In order to save space, many stainless steel air ducts are made of flat circles.
通風(fēng)管道的制造和加工，特別是對(duì)于一些小型企業(yè)，手工車(chē)間式企業(yè)，這樣的企業(yè)不會(huì)長(zhǎng)久生存下去。因?yàn)槲覀冋J(rèn)為，一個(gè)企業(yè)的發(fā)展離不開(kāi)其企業(yè)文化和戰(zhàn)略的發(fā)展。雖然主風(fēng)道仍為鐵板，但由于環(huán)保、使用壽命、防潮、隔音、承重等原因，在施工和保護(hù)方面存在很多缺陷。這導(dǎo)致了市場(chǎng)對(duì)新產(chǎn)品的需求來(lái)改善這一問(wèn)題。新型不銹鋼風(fēng)管的出現(xiàn)正好適應(yīng)了商場(chǎng)的需求。經(jīng)過(guò)多次工程應(yīng)用和實(shí)踐，逐漸被投資者所接受。
The manufacturing and processing of ventilation pipes, especially for some small enterprises, manual workshop enterprises, such enterprises will not survive for a long time. Because we believe that the development of an enterprise is inseparable from the development of its 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 market demand for new products to improve this problem. The emergence of new stainless steel air ducts just meets the needs of shopping malls. After many engineering applications and practices, it is gradually accepted by investors.
商場(chǎng)風(fēng)管一般分為三類(lèi):鍍鋅不銹鋼風(fēng)管、不銹鋼不銹鋼風(fēng)管和復(fù)合不銹鋼風(fēng)管。同時(shí)，不銹鋼風(fēng)管質(zhì)量好，適用性強(qiáng)，但價(jià)格昂貴。目前商場(chǎng)中使用較為廣泛的不銹鋼風(fēng)管是鍍鋅鋼板風(fēng)管。鍍鋅不銹鋼風(fēng)管基本上是不銹鋼風(fēng)管的特點(diǎn)，但其價(jià)格卻比不銹鋼風(fēng)管低三分之二甚至更低。復(fù)合不銹鋼風(fēng)道一般用于外部環(huán)境比較一般，對(duì)風(fēng)道要求不太高的地方。由于鐵片是簡(jiǎn)單的，在各種環(huán)境中發(fā)生化學(xué)反應(yīng)，導(dǎo)致腐蝕和生銹。然而，鋅在干燥的空氣中幾乎不會(huì)發(fā)生變化。在潮濕的空氣中，鋅的表面會(huì)形成良好的堿性碳酸鋅膜。不銹鋼風(fēng)筒主要是在風(fēng)筒的鐵片上鍍一層鋅，以保護(hù)鐵片。鍍鋅層經(jīng)鈍化、染色或涂覆光保護(hù)劑后，其保護(hù)和裝飾性能均有明顯改善。
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 it is expensive. At present, galvanized steel air ducts are widely used in shopping malls. Galvanized stainless steel air duct is basically the feature of stainless steel air duct, but its price is two-thirds lower or even lower than that of stainless steel air duct. Composite stainless steel air duct is generally used in places where the external environment is relatively general and the requirements for air duct are not too high. Because the iron sheet is simple, chemical reactions 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 surface of zinc. Stainless steel air duct is mainly coated with zinc on the iron sheet of the air duct to protect the iron sheet. After passivation, dyeing or coating with light protective agent, the protective and decorative properties of zinc coating are significantly improved.
通風(fēng)管道耐久性差。氯化鎂和氧化鎂的摩爾比是有科學(xué)依據(jù)的。氯化鎂的含量應(yīng)根據(jù)氧化鎂中活性鎂含量的測(cè)定來(lái)確定。然而，不合格產(chǎn)品的生產(chǎn)廠家不知道氧化鎂活性鎂含量的測(cè)定，更不用說(shuō)合理的摩爾比值。只知道氧化鎂和鹽水，凝固成風(fēng)管。風(fēng)道余氯離子含量大，在濕空氣環(huán)境中容易返鹵水，軟化系數(shù)低，使用壽命短。
The durability of ventilation duct is poor. The molar ratio of magnesium chloride to magnesium oxide has scientific basis. The content of magnesium chloride should be determined according to the determination of active magnesium content in magnesium oxide. However, the manufacturers of unqualified products do not know the determination of magnesium oxide active magnesium content, let alone a reasonable molar ratio. Only magnesium oxide and salt water are known to solidify into air ducts. The residual chloride ion content in the air duct is large, and it is easy to return brine in the wet air environment, with low softening coefficient and short service life.
