Pengaruh Panjang Partikel terhadap Kualitas Oriented Particle Board dari Bambu Tali (Gigantochloa apus Kurz.)

Abstract

RICKY HALOMOAN GEA. Effect of Particle Length Size on Oriented Particle Board Quality made from Tali Bamboo (Gigantochloa apus Kurz). Under supervised YUNUS AFFIFUDIN and APRI HERI ISWANTO. Some disadvantages of particle board lies in the stabilization of the low dimensions and strength. One of the factors that increase the stabilization of dimensions and strength were using orientation of perpendicular on board. The objective of this research was to analyze the physical properties and mechanical oriented particleboard (OPB) by particle length with using a mixture of urea formaldehyde (UF) and Isocyanate. Treatment of this research is particle size 3, 5, and 7 cm. Board made measuring 25x25 cm2 with a target thickness and density respectively by 1 cm and 0.75 gcm-3. OPB was manufactured in 3 layer with orientation of perpendicular in each layers. Layers ratio in face:core:back was 1:2:1. The amount of 12% UF and Isocyanate resin with 67% and 97% solid content each other for binding in manufacturing board. Mixing of particle and resin did with spraying of UF first, then to be continued with spraying of isocynate. The next step was hot pressing process in 1600C temperature as long 10 minutes and 30 kgcm-2 pressure. The results showed that parameter of physical properties for density did fulfill requirement of JIS A 5908-2003 and SNI 03-2105-2006. The results showed on parameter of mechanical properties for IB and MOR did fulfill requirement of JIS A 5908-2003 and SNI 03-2105-2006. Treatment of particle length. According to all the test parameter, 7 cm length size of particle were resulting of the best properties compared with 3 and 5 cm length size.
