The Pulverization and Its Dynamic Model of Waste Thermosetting Phenol-formaldehyde Resins

摘要

Pulverizing the waste thermosetting phenolformaldehyde resins by the self-developed machine which is used to recycle thermosetting plastics, studying the variable laws of fractions of different particle changing with the pulverization time, and establishing a pulverizing dynamic model by regression analysis. The results show that the particle distribution parameters b and m are not constants but the functions of pulverization time; the established equation of regression dynamic is high accurate which clearly describes the pulverization process.
