专注通风管道加工·排烟罩

At present, the four kinds of air ducts commonly used in kitchen smoke exhaust equipment are a selection problem for our use, because in many cases we can not make a correct judgment, which is also caused by our lack of understanding of it in terms of information, so today we will analyze the performance differences of four different air ducts in detail for you!

消音性能；

Silencing performance;

1、镀锌薄板风管：无消音功能，自身振动会产生声音，需加装消声器。

1. Galvanized sheet air duct: no silencing function, self vibration will produce sound, need to install muffler.

2、无机玻璃钢风管：无消音性能，隔音性能好于镀锌薄板风管，需加装消音器。

2. Inorganic glass fiber reinforced plastic duct: no noise attenuation performance, sound insulation performance is better than galvanized sheet duct, need to install muffler.

3、复合玻纤板风管：风管壁为多孔吸声材料，可省去专用消声器。

3. Composite fiberglass duct: the wall of the duct is made of porous sound-absorbing material, so special muffler can be omitted.

4、纤维织物风管：风管壁面为柔韧纤维织物，本身就是声音的不良导体和吸收体，自身不会发出声音，也能吸收设备噪音，而且随风管延长，效果更明显，可省去专用消声器。

4. Fiber fabric air duct: the wall of the air duct is made of flexible fiber fabric, which is the poor conductor and absorber of sound. It will not make sound, but also can absorb equipment noise. Moreover, with the extension of the air duct, the effect is more obvious, and the special muffler can be omitted.

防潮性能：

Moisture resistance:

1、镀锌薄钢板风管：易受潮湿腐蚀和锈蚀，在输送高含水率空气时更为严重。

1. Galvanized sheet steel duct: susceptible to Moisture Corrosion and corrosion, especially when conveying air with high moisture content.

2、无机玻璃钢风管：受原料配比的限制，其抗湿性能不稳定；

2. Inorganic glass fiber reinforced plastic air duct: limited by the proportion of raw materials, its moisture resistance is unstable;

3、复合玻纤板风管：不含易腐材料和零件，但由于它是一种多孔材料，应防止风管内部、端部和切口处长期浸水。

3. Composite fiberglass duct: it does not contain perishable materials and parts, but because it is a porous material, it is necessary to prevent the inside, end and incision of the duct from long-term immersion.

4、纤维织物风管：由于织物表面有冷气层，因此不会出现凝露，材料均为强疏水材料，不易受潮。尽管管子表面沾上了水，但由于管子表面有渗漏，所以干燥迅速。

4. Fiber fabric air duct: due to the cold air layer on the fabric surface, there will be no condensation, and the materials are strong hydrophobic materials, which are not easy to be affected by moisture. Although the surface of the pipe is stained with water, it dries rapidly due to leakage.

压缩强度：

Compressive strength:

1、镀锌薄钢板风管：强度较高，抗静压能力强，截面尺寸较大时，需要按规定进行加固。

1. Galvanized sheet steel duct: high strength, strong static pressure resistance, large section size, need to be reinforced according to the provisions.

2、无机玻璃钢风管：强度高，但比较脆弱，因其重量大，不易搬运，与风管碰撞容易发生酥裂和破裂。

2. Inorganic glass fiber reinforced plastic air duct: high strength, but relatively fragile, because of its heavy weight, not easy to handle, and air duct collision prone to crack and rupture.

3、复合玻纤板风管：可满足一般通风空调的承压要求，可承受1500Pa的风压。

3. Composite fiberglass duct: it can meet the pressure requirements of general ventilation and air conditioning, and can withstand the wind pressure of 1500pa.

4、纤维织物风道：弹性材料，但有良好的韧性。抗压力在2000Pa以上。

4. Fabric duct: elastic material, but with good toughness. The pressure resistance is above 2000 PA.

那么以上就是对于厨房排烟设备中通风管道的性能简述了，今天主要是从消音性、防潮性和压缩强度进行了分析，可以说已经是很丰富了，基本上我们能够想到和用到的特性都在上面了！

So the above is a brief description of the performance of the ventilation pipe in the kitchen smoke exhaust equipment. Today, it mainly analyzes the noise attenuation, moisture resistance and compression strength, which can be said to be very rich. Basically, the characteristics we can think of and use are all above!
