Pengaruh Post-Treatment Papan terhadap Stabilitas Dimensi dan Sifat Durabilitas Papan Partikel dari Bagase Sorghum

Abstract

SWESTY SRY DESIMA NADEAK. Post-Treatment Effect of Board to Dimensional Stability and Durability Properties of Particleboard Made From Sorghum Bagasse. Under supervised APRI HERI ISWANTO and TITO SUCIPTO. In general, the weakness of particleboard using of urea formaldehyde (UF) resin had a low dimensional stability. This reasearch will improve of that weakness by post-treatment technique used several water repellent materials. The objective of this research was to evaluated the post-treatment effect of board to dimensional stability and durability properties against to subterranean and dry termites. For each sample respectively was dyed into several water reppelent materials such as parafin, palm oil, silicon and waterproof for 3 minute. Furthermore, samples were oven dried at 50 0C temperature for 24 hours. The result showed that the density parameter was varied of 0,60 to 0,74 g/cm3. Board treated caused of increasing the density value. Water absorption and thickness swelling parameter of board were varied of 29,35% to 114,99% and 13,23 to 37,31 % respectively. Inspite of post-treatment resulting of improvement dimensional stability up to 65%, but the thickness swelling value did not fulfill standard. Furthermore, durability test showed that post-treatment able to improve of durability properties. For durability to subterranean termites attack resulted silicon treatment had the best durable to termites. Whereas for dry termites attack, waterproof treatment had the best durable
