The Effect Of Grain Size To Physico Mechanic Properties Of Particle Board Based On Rice Husk and Liquid Rubber Compound

Abstract

Particle board research produced from a number of grain size of Rice Husk and liquid rubber compound has been carried out. First particle board was produced by mixing rice husk with a number of grain size were 10-25 mesh; 25-50 mesh; 50-75 mesh and <75 mesh with liquid rubber compound as much as 45% to form a particle board with size of 5 x 10 x 7.5 cm in length, width and height and then dried. Then the particle board is pressed to get a thickness of 2.5 cm and then carried out the characterization of the MOR, MOE, screw pull resistance, water content and density. The results showed that the best rice husk particle size was obtained at 25-50 mesh grain size. At this grain size, the value of MOR, MOE, screw pull resistance, water content, and density of particle board were 9054,8 g/mm2; 15090 g/mm2; 69 g/mm2; 4,1% and 0,83 gr/cm3 respectively. The results of this study still do not meet the standards according to SNI 03-2105-2006
