高分子材质薄膜测试，eds能谱分析

挤出成型是当今工业中主要的塑料成型工艺。 通过使一个熔融的聚

合物通过合适的模具的孔而形成连续形状的过程（需要的形状工具）。

它可以比作挤牙膏管， 因为它产生一个长， 通常窄， 连续的对象。 成

型产品在吹风空气或水浴中冷却， 并在移动带上变硬。 棒， 管， 管，

片和薄膜（如食品包装） 挤压， 然后盘绕或切割到所需的长度。

现在主要用于工业是塑料成型的技术挤压成型工艺。

In the forming process, the polymer is forced to melt into a

continuous shape plastic through an appropriate mold hole (the

required shape of the tool) . It' s like squeezing toothpaste,

because it can provide a long, usually narrow, continuous

object. The products formed are cooled by air blowing in the

conveyor belt or cooled in the water bath. Bar, hose, tube,

sheet and film (such as food packaging) extrusion, and then curl

or shear extrusion to the required length.
