注塑工艺对通用膜料DFDA-7042产品力学性能的影响

Influence of Injection Molding Process on Mechanical Properties of Universal Membrane Material DFDA-7042

采用注塑成型方法制备了通用膜料DFDA-7042试样,研究了注塑条件对试样力学性能的影响,并对加工条件进行了优选.结果表明,适宜的注射压力在3 ～5 MPa之间,保压压力在3～4.5 MPa之间,保压时间设定在20 s,冷却时间设定在30～45 s之间,注射速率设定在100～ 120 mm/s.

General membrane material DFDA-7042 was prepared by injection molding process,and the effect of injection molding process on the mechanical properties of sample was studied.The processing conditions were preferred.The results showed that：the appropriate injection pressure was between 3 ～5 MPa,holding pressure was between 3 ～4.5 MPa,holding time was set to 20 s,cooling time was between 30 ～45 s,and injection speed was between 100 ～ 120 mm/s.
