STUDY OF PHYSICAL PROPERTIES MECHANICAL PROPERTIES AND THE DEVELOPMENT OF PARTICLEBOARD FROM DURIAN PEEL USING A COMPRESSION MOLDING PROCESS

Abstract

This research is the process study of producing particleboard from durian peel using the compression molding process. These studies are the physical and mechanical properties of particleboard from durian peel. The results found that the flexural test and the tensile test of furniture material sheets from durian peels at a ratio of durian pulp to glue water were 1:0.2, 1:0.4, 1:0.6, 1:0.8, 1:1, and 1:1.5, respectively. A specimen with dimensions of width 50 x length 200 x thickness 10 millimeters was tested with a machine. The universal testing machine of six samples in each ratio. It shows that the mechanical strength values increased when the ratio of water mixed with glue increased. The durian pulp has a better adhesion. This results are in a higher density as the ratio increases and at the ratio of 1:1.5, it has the highest strength and an average flexural strength of 5.74 MPa but it has not yet passed the criteria set by TISI 876-2004 with a flexural strength of not less than 14 MPa for plywood sheets with a thickness exceeding 6.0-13.0 millimeters. It has an average tensile strength value perpendicular to the surface of 0.49 MPa, which passes the criteria set by TISI standard, with the tensile strength value perpendicular to the surface not less MPa. than 0.40 for plywood with a thickness of more than 6.0-13.0 millimeters. For the testing of the burning rate of particleboard made from durian peels, it was found that the burning rate decreased when the ratio of water mixed with glue increased due to the increasing density of the workpiece at a ratio of 1:1.5 and it can stop the combustion by itself.
