查询词典 polymer

In terms of continuum mechanics and nonequilibrium irreversible thermodynamics theories, compressible Leonov constitutive model is derived to describe large recoverable elastic strain development in non-isothermal flow of compressible viscoelastic melts. It is tempting to specify the model and then compare it to basic rheological tests in the hope that such a model will yield a good description of the nonlinear viscoelasticity of polymer melts.

注射成型是聚合物的主要成型加工方法之一，成型过程中聚合物要经历熔体流动和固化等非等温、非平衡过程，由于聚合物的粘弹性，流动过程中建立的剪切应力、法向应力和大弹性形变在固化过程中不能完全松弛，在制品中形成残余应力和取向，对制品的机械和光学性能有着重要影响。
