PENGARUH PELAPISAN AKRILIK TERHADAP KUALITAS PAPAN PARTIKEL DARI LIMBAH BATANG KELAPA SAWIT
ABSTRACT: To reduce the waste of oil palm trunks can be done by
changing oil palm trunks into particle board. One way to improve the quality of
particle board is by doing coating treatment of acrylic. This study evaluated
the best acrylic level in improving the quality of oil palm trunk particle
board with isocyanate as the adhesive. Boards were made with size 25 cm x 25 cm x 1 cm with a target density of
0.7 g/cm3, felts temperature 160ยบ and pressure 25 kg/cm2 for 3 minutes.
Physical and mechanical properties were compared with SNI 03-2105-2006. The
treatment variations were acrylic levels (0%, 5%, 10%, and 15%) with 3
repetitions. Results showed that the values of the density, moisture content,
water absorption, thickness swelling, modulus of rupture, modulus of elasticity
and internal bond were respectively 0,46-0,60 g/cm3, 10,52-11,01%, 5,32-55.35%,
2,37-6,40%, 26,45-60,87 kg/cm2, 2619,15-5092,82 kg/cm2 and 2,28-4,61 kg/cm2.
All result values of physical properties testing except value of the moisture
content achieved the standards of SNI 03-2105-2006. Instead, all result values
of mechanical properties testing did not achieve the standards of SNI
03-2105-2006. The results showed that the particle boards with acrylic coating
treatment has better quality than the particle boards without the acrylic
coating treatment for the entire physical properties testing in addition to
moisture content. Best acrylic level for the coating treatment of oil palm
trunk particle board is 15%.
