The Effect Of Adhesive Content And Layer Ratio On The Quality Of Particleboard Sandwich
The Effect of Adhesive Content and Layer Ratio on the Quality of Particleboard Sandwich
Introduction
North Sumatra is renowned for its rich biodiversity, with numerous local plant species exhibiting great potential as raw materials for particleboard production. Two such species, incense wood and belangke bamboo, have been identified as promising alternatives for particleboard manufacturing. This study focuses on enhancing the strength of particleboard through modifications to Sandwich Particleboard (SPB), a board comprising a combination of two or more lignocellulose materials arranged in three layers: face layers (face), core, and back (back). The surface layer utilizes materials with high strength, while the core layer employs materials with lower strength.
Background
Particleboard sandwich is a type of engineered wood product that consists of a combination of two or more lignocellulose materials arranged in three layers. The surface layer is typically made from materials with high strength, while the core layer is made from materials with lower strength. The core layer is responsible for reducing the total weight of the product, while the surface layer provides resistance to loads and pressures. The quality of the final product is highly dependent on the right composition of each layer.
Methodology
In this study, particleboard sandwiches were tested with a target thickness and density of 1 cm and 0.75 g/cm³, respectively. The adhesive used was isocyanate with 5%, 7%, and 9% content variations, as well as layer ratios of 40/20/40 and 20/60/20. The board pressing was done using a hot pressing technique at 160 ° C with a time of 5 minutes and a pressure of 30 kgf/cm².
Results
The physical properties of particleboard sandwich, including density, water content, water absorption, and thickness development, ranged from 0.43-0.70 g/cm³, 6.75–13.11%, 46.3–96.9 %, and 6.19-13.89%, respectively. The mechanical properties, including modulus of elasticity, broken modulus, and internal bonds, each ranged from 7,179-142,858 kgf/cm², 12-655 kgf/cm², and 1,27-4.9 kgf/cm², respectively.
Discussion
The results of this study showed that the parameters tested met JIS A 5908-2003 standards, except for the F type board where some of the characteristics were still not in accordance with the standards. Based on the evaluation results, type A board was declared the best board in this study.
Additional Analysis and Explanation
The selection of raw materials and adhesive content plays a crucial role in making particleboard sandwich. The quality of the final product is highly dependent on the right composition, where each layer has its own role. A strong surface layer is responsible for providing resistance to loads and pressures, while lighter core layers function to reduce the total weight of the product.
Variation of adhesive levels also has a significant impact on the mechanical and physical properties of particleboard sandwich. At higher levels, the adhesion between particles will increase, which can produce better strength. However, too much adhesive can cause problems such as reducing water absorption and increasing water content, which can lead to long-term damage to boards.
The hot pressing process at the right temperature, adequate time, and appropriate pressure also contributes greatly to the final quality of the board. If this process is not done correctly, it can cause a decrease in mechanical properties, so that the board does not meet the established standards.
Conclusion
By paying attention to these factors, better development of particleboard sandwich can be done, utilizing local resources in North Sumatra. It also has the potential to open new opportunities in wood-based industries, which not only are economically profitable but also sustainable in terms of the environment. With further research and development of methods, the quality of particleboard sandwich can be increased, so that more applications in the industry can be found.
