INVESTIGASI TEKANAN OPTIMAL PADA PROSES PRESSURED SINTERING KOMPOSIT PLASTIK HDPE-KARET

ABSTRACT:  The  purpose  of  the  research  is  to  investigate  the  optimum compaction of pressured sintering process for HDPE-rubber composite. The  raw  materials  used  are  HDPE  plastic  waste  of  oil  bottle  and  unused  tire. These  materials  were  powdered  via  mechanical  grinding  manually.  The  plastic powder  size  of  -60  mesh  was  selected  to  be  roled  for  specimen.  Pressured sintering  process  for  producing  the  specimens  was  done    at  120oC    for  5 minutes. Parameter observed is the sintering pressure within range of 0,5 to 2 MPa  risen  0,5  MPa  incrementally.  Specimen  testing  involved  density,  bending strength  and  izot  impact  strength.  All  of  testing  was  conducted  on  ASTM standard testing. The result reveals that adding sintering pressured will increase density, flextural and impact strengths of about 14%, 52% and 17% respectively. The significant increasing properties occurs when the compaction reach to the optimum value, that is 1,5 MPa.
