Abstract

The environment-friendly abrasive materials of starch series has a wide range of application value such as deburring of plastic injection products, paint exfoliation and surface treatment of painted products and polishing, etc. In this study, an experiment of paint exfoliation was performed by using the environment-friendly abrasive materials made of cheap starch, and its performance was reviewed. By adjusting the grit size of abrasive materials, nozzle pressure, nozzle feed and number of nozzle repetition, paint could be exfoliated effectively. In this experiment, it was found that the most suitable condition was grit size 0.75~1.0 mm, nozzle pressure 0.4 MPa, nozzle feed 5 mm/min and number of processing repetition 2 times.
