The experimental results show that die pressure of PA6 and PA6/HDPE blends is reduced remarkably in the presence of ultrasonic wave during extrusion, but the melt temperature and mass flow rate of PA6/HDPE get increased.

- 在PA6/HDPE體系的超聲擠出過(guò)程中，超聲輻照所提供的能量場(chǎng)作用、高頻剪切振動(dòng)會(huì )導致共混物熔體口模溫度升高、口模壓力降低、擠出產(chǎn)量提高，因此，超聲輻照能有效改善共混體系的加工性能。
