Pengaruh Komposisi Perekat Urea Formaldehida dan Bahan Pengisi Styrofoam terhadap Kualitas Papan Partikel dari Limbah Batang Kelapa Sawit

Abstract

ZAINAL ABIDIN SYAH POLEM : The Influence of Composition Urea Formaldehyde Adhesives and padding Styrofoam Particle Board on the Quality of Waste Oil Palm Trunk. Supervised by TITO SUCIPTO and RUDI HARTONO. The waste oil palm trunks be redundant is a alternative basic commodity manufacture particleboards. The purpose of this study was to evaluate the physical and mechanical properties with the influence temperature and pressing time. Boards were made with size 25 cm x 25 cm x 1 cm with density of 0,75 gr/cm3 . Getting the best composition of adhesives and fillers. Particleboards using urea formaldehidyde adhesive, press 25kg/cm2 dan experiments were analyzed by non factorial with completely randomized design in 5 temperatures 130º, 130 and pressing times 10 min . Particleboard was tested for density, moisture content, water absorption, thickness swelling, modulus of rupture, compression strength parallel to the surface and internal bond. Result showed that pressing time and interaction temperature and pressing time have between the mixing rate urea formaldehyde and styrofoam significant influenced to the density. The combination of mixing optimal padding and adhesive by combination UF 90 : ST 10 density was 0,0627 g/cm3 moisture content was 7,45 %, water absorption was 91,03 %, thickness swelling was 9,99%, modulus of elasticity was 8660,58 kg/cm2 , modulus of rupture was 81,167 kg/cm2 and internal bond was 6,11 kg/cm2.
