CHANGES OF THE MECHANICAL PROPERTIES
IN POLYOXYMETHYLENE – POM RECYCLING PROCESS
|
| |
|
Summary :
|
|
THE REGION OF JOINVILLE AT SANTA CATARINA STATE OF BRAZIL AND ITS NEIGHBOURHOOD IS A LARGE AND IMPORTANT AREA OF PLASTIC PROCESSING, MOSTLY INJECTION. IN THIS FABRICATION PROCESS THERE ARE MATERIAL EXCESS DUE TO THE INJECTION CHANNELS AND DEFECTIVE PRODUCTS. SOME PART OF THESE MATERIAL EXCESS ARE THROWN AWAY BY THE INDUSTRY DUE TO THE POSSIBLE CHANGES IN THEIR MECHANICAL PROPERTIES. IN ORDER TO INVESTIGATE THE POSSIBILITY OF RECYCLING THESE MATERIALS IT IS NECESSARY TO DO A MORE DETAILED STUDY TO EVALUATE THEIR MECHANICAL PROPERTIES.
IN THE PRESENT WORK, THE MATERIAL USED WAS THE POLYOXYMETHYLENE - (POM), BECAUSE IT IS AN ENGINEERING PLASTIC WITH GREAT USE IN THE INDUSTRIES OF THE REGION.
THE AIM OF THE PRESENT WORK IS ANALYSE THE CHANGES IN THE MECHANICAL PROPERTIES BEHAVIOUR OF THE POM. TO DO THAT, THIS PLASTIC HAS BEEN INJECTED AND GROUND AFTERWARDS (THIS CONSIST OF ONE CYCLE OPERATION). IN THIS INVESTIGATION, TEN CYCLES OF INJECTION AND GRINDING HAVE BEEN DONE.
KEYWORDS: INJECTION , RECYCLING, POM, MECHANICAL PROPERTIES.
