Challenges in making plywood from oil palm trunk

Anis Mokhtar, . and Kamarudin Hassan, . and Ismadi Ismail, . and Choo Y.M., . and Mohd. Basri Wahid, . (2006) Challenges in making plywood from oil palm trunk. [Proceedings Paper]

Oil palm trunk has its own characteristics as compare to tropical wood. The process of making plywood from oil palm trunks need some adjustment during the primary processing to achieve maximum recovery of the materials. Two types of peelers were used to peel the trunk and the resulting veneers were than layered with grain direction perpendicular to each other for the production of plywood. Veneer drying was controlled under the optimum temperature until the veneers reached maximum moisture content of about 3. The temperature applied ranges between 130-150C and the drying time was about one hour. Two types of binders were used with different formulations for indoor and outdoor purposes. After gluing the veneers were subjected to cold pressing in order to straighten the veneers and to transfer the resin to adjacent veneer members. The resulting plywood with different thickness was then subjected to hot pressing at varying temperature 105-110C pressure 40-135 kg/cm2 and time 30 sec - 10 min. The oil palm trunk plywood was subjected to physical and mechanical testing and the results shows that oil palm trunk plywood meets the strength requirements as stipulated in the Japanese Standard JAS 233:2003.

Abstract

Oil palm trunk has its own characteristics as compare to tropical wood. The process of making plywood from oil palm trunks need some adjustment during the primary processing to achieve maximum recovery of the materials. Two types of peelers were used to peel the trunk and the resulting veneers were than layered with grain direction perpendicular to each other for the production of plywood. Veneer drying was controlled under the optimum temperature until the veneers reached maximum moisture content of about 3. The temperature applied ranges between 130-150C and the drying time was about one hour. Two types of binders were used with different formulations for indoor and outdoor purposes. After gluing the veneers were subjected to cold pressing in order to straighten the veneers and to transfer the resin to adjacent veneer members. The resulting plywood with different thickness was then subjected to hot pressing at varying temperature 105-110C pressure 40-135 kg/cm2 and time 30 sec - 10 min. The oil palm trunk plywood was subjected to physical and mechanical testing and the results shows that oil palm trunk plywood meets the strength requirements as stipulated in the Japanese Standard JAS 233:2003.
