| 中文摘要: |
| 从塑料和聚合物的特性、塑料焊接方法分类、焊接的基本步骤、焊接特点方面介绍了塑料和聚合物的超声焊接。一般认为，超声焊接的研究内容主要是研究与超声有关的焊接声参数方面的问题。其实，在国外更多地是从材料方面研究焊件在焊接过程中物理性能的变化，对此做了较详尽的介绍。超声波在热塑性粘弹性介质中传播相对于金属介质来说有较大耗损，文中也介绍了测定粘弹性介质复杨氏模量的基本方法。 |
| 英文摘要: |
| The characteristics of plastics and polymers, the classification method of plastics welding, the fundamental steps and the characteristics of ultrasonic welding for plastics and polymers are introduced in this paper. It is generally considered that ultrasonic welding is mainly focused on the relevant ultrasonic parameters. Actually, changes of welded parts in physical properties during the welding process have been more concerned in some developed countries, so a more detailed introduction is made in this paper. There is more consumption of ultrasonic propagation in thermoplastic viscoelastic materials than in metal ones, therefore a brief introduction for the determination of the basic methods of complex young's modulus of viscoelastic materials is also given. |
