Modifying of Particle Boards from Rice Husk and Pinus Merkusii Sawdust and Using Soybean Waste Waters Based Adhesive.

Abstract

Research of modifying particle board has been prepared by mixing of pinus merkusii sawdust and rice husk, where used of adhesive base on Boiled Soybean Water (BSW) has been done. The research utilize the rise husk and sawdust pines mixed, and used of a renewable and environmental adhesive to replace the toxic and carcinogenic one. The testing of adhesive included are; colour, pH, solid contain, gelatination time, density and viscosity. Result showed yellowish colour, 10 of pH, 44.70 % of solid contained, 56.29 minutes of gelatination time, and 1.1656 g/cm3 and 182.4387 cP of viscocity respectively. While the particle boards testing include are density, moisture, immersion, thickness, Modulus of Rapture (MOR) and Modulus of Elasticity (MOE). The particle board best ratio it was 1:4 (Rice husk: pinus merkusii sawdust). Result of each parameter are, 0.7735 g/cm3 of density, 5.79 % of moisture, however the immersion for 2 hours is 26.90 % and immersion for 24 hours is 39.77 %, 101.1592 kg/cm2 of MOR and 18,248.3063 kg/cm2of MOE.
