其實油煙機的管道大致可以分為兩種，一種是金屬管道另一種是塑料管道。金屬管道大多數是鋁箔材質的，塑料管道分為兩種，PP管（聚丙烯）和PVC管（聚氯乙烯）；那這三種材料之間都有什么區別
In fact, the pipes of the range hood can be roughly divided into two types, one is metal pipes and the other is plastic pipes. Most metal pipes are made of aluminum foil, and plastic pipes are divided into two types, PP pipes (polypropylene) and PVC pipes (polyvinyl chloride); What are the differences between these three materials
鋁箔管。鋁箔管的氣密性強，更加結實耐用。不會散發出有毒的氣味，對人的健康沒有危害，而且它不透明油漬再多外面也看不見，受熱性也比塑料管好很多，但是要稍高一點，所以一些廠家配備的鋁箔管都比較短。安裝時，可能會出現長度不夠的問題。
Aluminum foil tube. The aluminum foil tube has strong air tightness and is more durable. It does not emit toxic odor and does no harm to human health. It is also invisible even if it has many opaque oil stains. Its heat resistance is much better than that of plastic tubes, but the price is slightly higher, so some manufacturers have short aluminum foil tubes. During installation, the length may not be enough.
管（聚丙烯）。耐腐蝕，用于油煙機的排煙管是較為合適的。可回收，較為而且可以做硬管也可以做軟管，連接和拆卸都十分方便，安裝較為簡單。不結垢，清理起來也更為方便
Pipe (polypropylene). Corrosion resistant, non-toxic smoke exhaust pipe for range hood is more appropriate. It is recyclable, environmentally friendly, and can be used as hard pipe or hose. It is very convenient to connect and disassemble, and it is relatively simple to install. No scaling, more convenient for cleaning
管（聚氯乙烯）。相較于前兩種管道來說，它有一定的毒害性，受熱能力也差一點。不過用作廚房的排煙是沒有太大問題的。這種管件在廚房排氣管中運用的不多，但是如果煙道比較長的話可以考慮接PVC硬管，因為普通的軟管容易脫落，到時候煙排不出去就麻煩了。
Pipe (PVC). Compared with the first two kinds of pipes, it has certain toxicity and poor heating capacity. However, there is no big problem when it is used as smoke exhaust in the kitchen. This kind of pipe fitting is seldom used in the kitchen exhaust pipe, but if the flue is relatively long, you can consider connecting the PVC hard pipe, because the ordinary hose is easy to fall off, and it will be troublesome if the smoke cannot be discharged.
不過并不是選擇好排煙管事情就算完結了，在安裝過程中，還要注意到這三點。
However, it is not a matter of choosing a good smoke exhaust pipe that the matter is over. In the installation process, we should pay attention to these three points.
煙道不要設置的過長，不然安裝麻煩，排煙也不方便。
The flue shall not be set too long, or it will be inconvenient to install and smoke exhaust.
轉彎處盡量保持圓滑，彎度盡量放大，能不轉彎的地方就不要轉彎。
Keep the turning as smooth as possible, enlarge the bending as much as possible, and don't turn where you can.
接口處要保證緊密嚴實，防止油煙溢出，影響效果
The interface shall be tight and tight to prevent lampblack from overflowing and affecting the effect
安裝排煙管是只有做好這3點，油煙機才能達到理想的排煙效果，而且上面這三種不同材質的管道各有優缺點，正常情況下用聚丙烯管就可以了，想要美觀一點就選擇話鋁箔管，煙道過長就選用PVC硬管，可以根據家里的具體情況來自由選擇，實用性很強。
The installation of smoke exhaust pipe is the only way to achieve the ideal smoke exhaust effect of the range hood. In addition, the above three pipes of different materials have their own advantages and disadvantages. Under normal circumstances, polypropylene pipes can be used. If you want to look beautiful, aluminum foil pipes can be selected. If the flue is too long, PVC hard pipes can be selected freely according to the specific situation of the home, which is very practical.
