鍍鋅板螺旋風管制作加工工藝特點及優勢

Characteristics and advantages of manufacturing and processing technology for galvanized sheet spiral air ducts

（1）外觀質量高。成形后的風管內壁潤滑，外壁流利；

(1) High appearance quality. The inner wall of the formed air duct is lubricated, and the outer wall is smooth;

（2）風管強度大。由于外壁咬口構成的螺旋線棱筋平均散布，起到一個平均增強筋的效果，其單元強度大于通俗咬口式風管；

(2) The strength of the air duct is high. Due to the evenly distributed spiral ribs formed by the bite on the outer wall, they have an average reinforcing effect, and their unit strength is greater than that of the common bite style air duct;

（3）風管密封功能優越。由于是機械加工，能削減報酬操作掉誤，確保風管緊密，漏風量遠小于現行標準規則值；

(3) The sealing function of the air duct is superior. Due to its mechanical processing, it can reduce the cost of compensation and ensure that the air ducts are tight, and the air leakage rate is much lower than the current standard rules;

（4）資料用量削減。因為螺旋式風管單元強度大于通俗風管，故同類規格風管所用的卷材厚度可以減小一個型號，且風管節長比通俗咬口式風管大，相同長度的風管節口數目分明削減，加之采用無法蘭銜接，可節流很多原資料；

(4) Reduce data usage. Because the strength of the spiral type air duct unit is greater than that of the ordinary air duct, the thickness of the coil used for similar specifications of air ducts can be reduced by one model, and the length of the air duct section is larger than that of the ordinary bite type air duct. The number of air duct sections of the same length is significantly reduced, and the use of flange free connections can save a lot of raw materials;

（5）加工速度快、精度高。由于是機械流水線加工，可不受功課手技能程度制約，對進步風管加工質量非常有益。

(5) Fast processing speed and high precision. As it is a mechanical assembly line processing, it is not limited by the skill level of the workers, which is very beneficial for improving the quality of air duct processing.

什么是通風管道及其產品特點淺析？

What is ventilation duct and its product characteristics?

1、通風管道防火性能好：當前普遍存在的問題是成品通風道燃燒性能和耐火限未經家有關部門檢測，且部分通風道材料的燃燒性能、管壁厚度不符合要求。

1. Good fire resistance performance of ventilation ducts: The current common problem is that the combustion performance and fire resistance limit of finished ventilation ducts have not been tested by relevant departments at home, and the combustion performance and wall thickness of some ventilation duct materials do not meet the requirements.

2、造價低：通風管道與傳統磚砌通風道比，能節約工程造價40%左右；

2. Low cost: Compared to traditional brick ventilation ducts, ventilation ducts can save about 40% of project cost;

3、輕質高強：與傳統磚砌通風道比，菱鎂通風道自重輕、強度高，能大幅度降低建筑物的承受荷載；

3. Lightweight and High Strength: Compared with traditional brick ventilation ducts, magnesite ventilation ducts have a lighter weight and higher strength, which can significantly reduce the load-bearing capacity of buildings;

4、設計靈活：通風管道可根據預留洞的大小，隨時調整管道的規格尺寸；

4. Flexible design: The ventilation duct can be adjusted in size according to the reserved hole size at any time;

5、設計獨特：通風管道的開口上安裝了煙氣止回閥和防火隔離門，可以有效防止串味和串火；

5. Unique design: The opening of the ventilation duct is equipped with a smoke check valve and a fire isolation door, which can effectively prevent odor and fire;

6、通風管道施工簡單，增加了室內空間，密閉性好、不返煙、不返臭，能大幅度改善室內環境。

6. The construction of ventilation ducts is simple, increasing indoor space, with good sealing, no smoke or odor return, and can greatly improve the indoor environment.
