The Effect of Particle Size and Adhesive Content on Physical and Mechanical Properties of Particle Board from Palm Oil Stem Waste with Formaldehyde Urea Adhesive
Exploring the Potential of Oil Palm Stem Waste: The Effect of Particle Size and Adhesive Levels on the Properties of Particle Board
Palm oil stem waste, a residual material that has been considered as a waste product, has been found to store great potential to be processed into added value products. One of the uses is as raw material for making particle boards, an alternative to an environmentally friendly solid wood. This study investigated the effect of particle size and urea formaldehyde adhesive level on the physical and mechanical properties of particle board from oil palm stem waste.
Background and Significance
The use of oil palm stem waste as a raw material for making particle boards is a promising alternative to traditional solid wood. Particle boards are made from wood particles that are pressed together with adhesives to form a solid board. The use of oil palm stem waste as a raw material can help reduce waste and support the principles of circular economy. However, the physical and mechanical properties of particle boards made from oil palm stem waste are not well understood, and more research is needed to develop this technology.
Research Methodology
This research was conducted using a factorial experimental design. Three particle sizes (20 mesh, 35 mesh, and 50 mesh) were combined with three formaldehyde urea adhesive levels (8%, 10%, and 12%). The particle board was formed with a pressure of 25 kgf/cm² at 130 ° C for 10 minutes, producing a board with a size of 25 x 25 x 1 cm³ and a density of 0.7 gr/cm³.
Results and Discussion
The results showed that the combination of particle size and adhesive levels had a significant effect on the physical and mechanical properties of the particle board. The density of the particle board ranged from 0.52 to 0.59 gr/cm³, water content ranged from 9.33% to 10.43%, water absorption ranged from 0.73% to 1.26%, thick swelling ranged from 0.48% to 18.93%, bond strength ranging from 0.87 to 3.22 kg/cm², the modulus of rupture (MOR) ranged from 23.84 to 81.86 kg/cm², and the modulus of elasticity (MOE) ranged from 2882.25 to 9221.32 kg/cm².
The results of this study indicate that the density and moisture content of the particle board meets SNI 03-2105-2006 standards. Thick swelling and bond strength also meet the standards. However, the modulus of rupture (MOR) and the modulus of elasticity (MOE) have not met the standards.
This study shows that the interaction between particle size and adhesive levels is very significant to the strength of the deep bond, MOR, and MOE particle board. The particle size significantly affects thick swelling, deep bond strength, MOR, and MOE. Adhesive levels significantly affect the water content, thick swelling, deep bond strength, MOR, and MOE.
Optimal Conditions
Optimal conditions are achieved at 8% adhesive level and 35 mesh particle size. This condition produces a particle board with relatively good physical and mechanical properties, although it has not fully met SNI standards.
Conclusion and Recommendations
The results of this study open up great opportunities to develop the technology of making particle boards from oil palm stem waste. The development of this technology needs to be focused on efforts to improve MOR and MOE, so that the particle board produced can meet the standards and be able to compete with particle boards made of solid wood. The use of oil palm stem waste as raw material for making particle boards also opens opportunities to reduce waste and support the principles of circular economy.
Future Research Directions
Future research directions include:
Improving the MOR and MOE of particle boards made from oil palm stem waste
Developing new adhesives that can improve the physical and mechanical properties of particle boards
Investigating the effect of other variables, such as temperature and pressure, on the physical and mechanical properties of particle boards
Developing new technologies for making particle boards from oil palm stem waste
Limitations of the Study
This study has several limitations, including:
The use of a small sample size
The use of a limited number of particle sizes and adhesive levels
The lack of control over other variables, such as temperature and pressure
Recommendations for Future Research
Future research should aim to address these limitations and provide a more comprehensive understanding of the physical and mechanical properties of particle boards made from oil palm stem waste.
