通風管道受到市場的大力歡迎，不僅因為其自身功能的突出特點，也因為其低廉的非常適合推廣并普及，因而非常受到諸多廠家的歡迎。下面
濟南通風管道加工廠家為大家介紹就是通風管道質量判斷的四大標準，希望可以給大家一些幫助!
Ventilation duct is greatly welcomed by the market, not only because of its outstanding features, but also because its low price is very suitable for promotion and popularization, so it is very popular with many manufacturers. The following is the four standards for judging the quality of ventilation pipes introduced by Jinan ventilation pipe processing factory. I hope it can help you!
一、美觀：這屬于技術上的問題,需要通風管道的工程團隊加以設計,施工及完善。
1、 Aesthetics: This is a technical problem, which needs the design, construction and improvement of the ventilation pipe engineering team.
二、合理：客觀性的問題,只要能達到客戶的要求又不違反相關標準,都能說是合理的。
2、 Reasonable: the problem of objectivity can be said to be reasonable as long as it can meet the customer's requirements without violating the relevant standards.
三、材質：只要能達到工程要求,一切都不是問題,你可以用相當的物質來取代一種物質,比如說我們常見的通風工程中經常用到的帆布等。
3、 Material: as long as it can meet the engineering requirements, everything is not a problem. You can replace a substance with a comparable substance, such as canvas, which is often used in our common ventilation projects.
四、實用：這點應該是重要的一點,也是客戶們所追求的一點,只有達到了工程的效果,這樣客戶才能認可我們的產品。
4、 Practical: this should be an important point and also a point pursued by customers. Only when the engineering effect is achieved can customers recognize our products.
此外通風管道是中空的，一般都是用來通風的一種管材，一般都是圓形或者方形的，通風管道的加工對風管的要求也是非常的大，這樣也是為了操作人員的，所以在對通風管道加工安裝的時候一些問題是一定要注意的，比如：
In addition, the ventilation duct is hollow, which is generally a kind of pipe used for ventilation. It is generally round or square. The processing of the ventilation duct has great requirements on the air duct, which is also for the safety of operators. Therefore, some problems must be paid attention to during the processing and installation of the ventilation duct, such as:
通風管道加工的過程中應該盡量避免出現縱向接縫，但是一定不能出現橫向接縫。而且通風管道的咬口縫和四角的縫隙處，需要按照設計潔凈等級要求，然后還要采用密封膠將其堵嚴。另外通風管道板材的連接縫的密封面應該設在通風管道壁的正壓側。
Longitudinal joints shall be avoided as much as possible during the processing of ventilation pipes, but transverse joints must not occur. Moreover, the undercut joints and the four corners of the ventilation pipe shall be sealed with sealant according to the design cleanliness level requirements. In addition, the sealing surface of the connection joint of the ventilation duct plate should be set at the positive pressure side of the ventilation duct wall.
如果是彩色涂層鋼板通風管道的話，應該保持內壁是光滑的，而且通風管道加工的過程中，還不能將涂層損壞，若是出現損壞的部位，需要用環氧樹脂涂刷在表面即可。另外通風管道加工的過程中，還要做好防腐蝕措施，不能使用抽芯鉚釘，而且在通風管道零件裝配的時候，這些零件都要經過鍍鋅處理才行。
If it is a color coated steel plate ventilation pipe, the inner wall shall be kept smooth, and the coating shall not be damaged during the processing of the ventilation pipe. If the damaged part occurs, it needs to be painted on the surface with epoxy resin. In addition, anti-corrosion measures shall be taken during the processing of ventilation pipes, and blind rivets shall not be used. Moreover, during the assembly of ventilation pipe parts, these parts shall be galvanized.
What are the standards for judging the quality of ventilation ducts? The above has explained the problem from several aspects. Of course, you can take a careful look at the precautions. For more information, please visit our website http://m.pvcbox.cn Right.
