pp風(fēng)管在選材和連接時怎么做

How to make PP air duct in material selection and connection

pp風(fēng)管在選用和連接方面需要注意哪些方面呢？很多來進行這種材料的管道安裝的工程師們由于對這種新型的不太熟悉，所以有時候在選材和連接方面有時候會不知道該如何去做。

What should be paid attention to in the selection and connection of PP air duct? Many of the engineers who come to install this material are not familiar with this new type of pipe, so sometimes they don't know how to select materials and connect them.

其實在pp風(fēng)管道選用時候，要考慮這種安裝此類管道周圍的環(huán)境，要確定溫度是否在壹佰攝氏度以上，溫度越高，需要選擇的安全系數(shù)就要越高一些的，這樣能保證使用壽命，而對于溫度低于四十?dāng)z氏度的環(huán)境，要注意選擇抗壓能力比較***的，而且盡量選擇管壁比較均勻的才***。一般在連接方面我們常常用的就是熱風(fēng)焊連接以及熱熔對接連接，這兩種連接方式在連接的過程中，溫度一定要合適以及穩(wěn)定，而且焊接的時候要注意保持焊接表面清潔，避免摻雜很多雜質(zhì)而影響性能，***重要的是在控制溫度方面盡量選擇pp風(fēng)管道的熔融狀態(tài)，不要有燒焦的情況才***，在焊接的時候也要注意連接的兩個本體不要存在縫隙。

In fact, when selecting PP air duct, we should consider the surrounding environment of the installation of such duct, and determine whether the temperature is more than one hundred degrees Celsius. The higher the temperature is, the higher the safety factor to be selected will be, so as to ensure the service life. For the environment with the temperature lower than forty degrees Celsius, we should pay attention to the selection of the one with better compressive capacity, and try to choose the pipe wall ratio It's better to be more even. In general, we often use hot-air welding connection and hot-melt butt connection in connection. In the process of connection, the temperature must be appropriate and stable. In addition, when welding, we should pay attention to keep the welding surface clean and avoid the influence of many impurities on the performance. The most important thing is to try to choose the melting state of PP air pipe in terms of temperature control It's better to have scorching condition. When welding, it's also necessary to pay attention to that there is no gap between the two connected bodies.
