摘要

Using the capillary rheometer to study the effect of shear rate, shear stress and temperature of Japanese and domestic PPS resin(fiber grade) on the apparent viscosity, index of non-Newtonian and viscous flow activation energy. The results show that with the increase of shear rate and temperature, compared to the domestic sample, Japanese sample has higher apparent viscosity, smaller non-Newtonian index(n), lower viscous flow activation energy, and smaller sensitivity to temperature. The Japanese specimens are suitable for processing and forming under high shear rate and spinning speed, but the domestic specimens are suitable for processing and froming under low shear rate and spinning speed.
