铜和塑料复合物及铜和塑料混合物分离：如电子线路板覆铜铜箔的回收，废旧铜线铜和塑料的回收。
Copper and plastic compounds and mixtures of copper and plastic separation: such as electronic circuit board copper foil recycling, waste plastic recycling copper and copper wire.
注射工艺过程就是从给料斗送进粉状或粒状的塑料混合物，经过定量区和熔化区，然后将其注射到模具型腔中。
The process consists of feeding a plastic compound in powdered or granular form from a hopper through metering and melting stages and then injecting it into a mold.
总的来说，混合废旧塑料制备的复合材料的力学性能要低于纯塑料混合物制备的复合材料，尤其是拉伸断裂伸长率。
In General, the mechanical properties of composites made from recycled plastic blends were inferior to those made from virgin plastic blends, especially in elongation break.
