Abstract
The present application relates to the technical field of processing of degradable materials, and in particular to a granulation processing method for a low-melt-index degradable material, and a shaped body prepared thereby. The granulation processing method for the degradable material provided by the present invention comprises: reducing the temperature of a screw rod for multiple times and increasing the rotating speed of the screw rod during an extrusion crystallization granulation process. The granulation processing method provided by the present invention is beneficial to improving the crystallization rate of the material during the granulation processing process, and reduces the influence caused by shear heat and relatively high processing temperature, thereby obtaining a granular material having a lower melt index.
