KUALITAS PAPAN PARTIKEL KENAF MENGGUNAKAN PEREKAT LIKUIDA DENGAN FORTIFIKASI MELAMIN FORMALDEHID
ABSTRACT: The qualities of
core kenaf particle boards were studied.
The boards were made of core kenaf particles and their liquids fortified
by melamine formaldehyde. Core kenaf liquids were prepared using 20 – 60 mesh
particles, phenol : formaldehyde ratio of 0,5, based on Masri (2005). SNI 06-4567-1998 and JIS A 5908-2003 were
used to grade the kenaf liquids and particle board. Factorial analysis 3 x 3 in Complete
Randomized Design was applied with 2 replications. Glue spread with 3 levels (10, 15 and 20% of
the oven dry weight kenaf particles) and fortification MF with 3 levels (15, 30
and 45% of the solid content of the kenaf liquids) were used. Kenaf particles were cold soaked prior
bonding. The condition of bonding
operation in making particle board were : pressure of 20 kgf/cm2 at 160ºC for
12 minutes.
The best result of particle board produced by 20% glue spread and 45% MF
fortification with the properties as follows : density of 0,7 g/cm3, moisture
content of 6,6%, water absorb ability of 55,6%, thickness swelling of 16,6%,
screw holding strength of 641,2 N, internal bond of 0,86 N/mm2, MOE of 2131,9
N/mm2, and MOR of 15,3 N/mm2.
Fortifications doesn’t significantly affect the quality of the particle
boards.
