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.
