Research on Crushing and Regeneration Mechanism of Thermosetting Plastic Based on Mechanical and Physical Method

Abstract

Abstract:

This paper puts forward the crushing and regeneration process of thermosetting plastic based on mechanical and physical methods. For the crushing process under a variety of mechanical forces, this paper conducted comprehensive analysis of crushing mechanics, fracture mechanism and the crushing effects. Through the experimental studies of thermosetting phenolic resin, it is proved that under appropriate rotational speed, time and temperature conditions, the physical characteristics and mesh crosslinking molecular structure of thermosetting plastic change due to mechanical and physical function,so that the thermosetting plastic restores crystallized ability to a certain extent. 

Key words: thermosetting plastic, fracture mechanism, crushing, regeneration
