PENINGKATAN KUALITAS PAPAN KOMPOSIT LIMBAH BATANG KELAPA SAWIT (ELAEIS GUINEENSIS JACQ.) DENGAN BERBAGAI WATER REPELLENT
ABSTRACT: Ever-increasing
demand for wood and forest potential of shrinking demand the use of wood in an
efficient and prudent, for example by utilizing waste oil palm trunks which
have not been optimally utilized a high-quality products for the future. The
purpose of this study was to test the stability and strength of composite
boards from waste oil palm trunks with a ratio of water-resistant coating
acrylic of various brands. The hypothesis of this study is the differences
between different brands of acrylic that affect the physical properties and
mechanical properties of composite boards from oil palm trunk waste. There are
three treatments in this study, which refers to the first treatment of the
outer coating of the composite board with a water repellent Aquaproof brand,
treatment of both the outer coating with MultiGuard composite board, and the
third with a Waterproof coating. Testing of physical properties and mechanical
properties refer to JIS A 5908-2003. The results showed that physical
properties of the density has reached the target density with a value of 0.8
gr/cm3, where the density range of 0.78 - 0.82 gr/cm3, water content ranged
from 8:23 to 9:11%, water absorption ranged from 8.69 - 10.86%, the development
of thick for 2 hours ranged between 3.1 - 4.92% and thickness development
during the 24 hours range from 11:34 to 15:53%. Meanwhile, for the results of
testing the mechanical properties of obtained results of an internal bond 8:19
- 10.81 kg/cm2, a strong grasp of the screw 56.29 - 59.55 kgf, MOE 21124.08 -
31852.83 kg/cm2 and MOR reached 279.62 - 378.36 kg/cm2.
