" You have thermosets in cars. You have thermosets in buildings" .

“汽车中有热固性。 建筑物中有热固性” 。

Some other polymers like polyurethane or Bakelite are thermoset.

其他一些聚合物如聚氨酯或电木是热固性。

So far, though, there's no way to recycle what's known as thermoset plastics.

不过，到目前为止， 还没有办法回收所谓热固性塑。

" Most of the plastic components in an aircraft are thermoset materials, " says Ica Manas-Zloczower.

“飞中大部塑部件都是热固性， ” Ica Manas-Zloczower 说。

Polyethylene can actually be converted into a thermoset polymer by introducing cross-links, basically molecular bridges between those polymer chains.

聚乙烯实际上可以通过引入交联转化为热固性聚合物，基本上是这些聚合物链之子桥。

A similar approach can work for other types of thermoset plastics, too, Manas-Zloczower says.

Manas-Zloczower 说， 类似方法也适用于其他类型热固性塑。

" The idea to convert existing thermosets into vitrimers is very appealing, " says Tanja Junkers.

“将现有热固性转化为 vitrimers 想法非常有吸引力， ” Tanja Junkers 说。

Some vitrimer plastics might even perform better than the original thermosets for some uses.

对于某些用途， 一些 vitrimer 塑甚至可能比原来热固性塑表现得更好。

The team combined bits of one type of thermoset plastic with a tiny amount of a zinc-based compound.

该团队将一种热固性塑碎片与少量锌基化合物结合在一起。

Last year, Manas-Zloczower and Liang Yue, also at Case Western, were part of a team that developed a process to convert thermoset plastics into such vitrimers.

去年，同样在 Case Western Manas-Zloczower 和 Liang Yue 所在团队开发了一种将热固性塑转化为此类 vitrimer 工艺。

The very properties that make thermoset plastics so useful, in that they keep their shape and integrity under extreme conditions, mean that they can't be broken down and rebuilt by the vast majority of recycling plants.

热固性塑之所以如此有用是因为它们在极端条件下还可以完整保持原状，这也意味着绝大多数回收厂无法解和重塑它们。
