Then there's code number 3, PVC, which is made of a polymer called " polyvinyl chloride" .

然后是代码 3，聚氯乙烯。它是由一种叫聚氯乙烯的聚合物组成的。

But while that makes cellular PVC more lightweight, it just isn't like wood.

但是，虽然这使得蜂窝聚氯乙烯更轻，但它不像头。

All right, what if we use this two-inch PVC to reinforce the center cross-support?

好的，如果我们用这两英尺的聚氯乙烯来改造中心支撑结构怎样？

And polychloroethene is more commonly called polyvinyl chloride, or PVC.

聚氯乙烯通常称聚氯乙烯或 PVC。

One material that's gained traction as a wood alternative is something that's used as trims for houses called cellular PVC.

一种代品获得牵引力的料是一种叫做蜂窝聚氯乙烯的房屋装饰料。

They also include a lot of plastic foams, such as polyvinyl chloride and polyethylene.

它们还包括很多塑料泡沫，例如聚氯乙烯和聚乙烯。

But some, such as polyvinyl chloride, are known to cause cancer.

但有些料， 例如聚氯乙烯， 已知会致癌。

Soon after came polyvinyl chloride, or vinyl, which was flexible yet hardy.

不久之后出现了聚氯乙烯或乙烯基，它既柔韧又坚固。

Well you get polychloroethene, kinda, that's not what we call it.

好吧，你得到聚氯乙烯， 有点，那不是我们所说的。

It features a custom sensing system called 'HuggieChest' which incorporates two inflated chambers of polyvinyl chloride to imitate a soft chest.

它的特点是一个名“HuggieChest”的定制传感系统，该系统包含两个聚氯乙烯膨胀腔室，以模仿柔软的胸部。

When dropped into a river (usually by helicopter), PLUG's pumps switch on automatically and begin forcing water into the balloon through a valve.

它是由聚酯纤维和聚氯乙烯制的圆柱形气球，并安装了发动机带动的水泵。把这个装置投入河中（一般使用直升机），水泵就自动开始工，通过一个阀门把河水注入气球。

Then, there was planned to be a trampoline with a poly-like PVC pipe, but that would just become bird perches and then you'd have to deal with bad water quality.

然后，计划建造一个带有聚氯乙烯管的蹦床，但那只会成鸟的栖息地， 然后你就必须应对糟糕的水质。

These are combined in a chemical reaction to create ethylene dichloride, which is turned into a gas, and then, through a process called " polymerization" , it becomes a fine, white powder called polyvinyl chloride, or PVC.

它们在化学反应中结合，生成二氯乙烯，变成气体，然后，通过一个叫做“聚合”的过程，变成一种白色的细粉末，叫做聚氯乙烯，简称PVC。
