Assessment of four Sarawak reforestation species for manufacture of particleboard

Nigel P.T.Lim, . and Pek Y.K., . (2004) Assessment of four Sarawak reforestation species for manufacture of particleboard. [Proceedings Paper]

Four reforestation species namely Acacia mangium Sentang Azadirachta excelsa Rubberwood Hevea brasiliensis and Engkabang jantong Shorea macrophylla were evaluated in terms of suitability for particleboard production. The mean wood densitiesof these species were 441kg/m3 510kg/m3 and 330kg/m3 oven-dried basis respectively. Single-layer and three-layer particleboards of target densities 600. 700 and 800kg/m3 were produced using urea formaldehyde resin as binder. The strength properties and dimensional stability of these boards were determined and assessed for their relative compliance to Japanese Industrial Standard JIS A 5908-1994. These board properties were also compared with that of commercial particleboards. Blow-out problems were encountered for Enkabang jantong and Sentang at targeted board densities of 700kg/m3 and 800kg/m3 respectively.Most of the board fabricated met the minimum strength requirements for Type 13 of JIS except of Rubberwood and Sentang at 600kg/m3 board density. In terms of dimensional stability the thickness swelling values of these species were all below the maximum allowable limit of 12. Amongst the four species Acacia mangium boards processed the best strength properties and lowest thickness swelling. All the four reforestation species were assessed as potentially suitable raw material for particleboard production.

Abstract

Four reforestation species namely Acacia mangium Sentang Azadirachta excelsa Rubberwood Hevea brasiliensis and Engkabang jantong Shorea macrophylla were evaluated in terms of suitability for particleboard production. The mean wood densitiesof these species were 441kg/m3 510kg/m3 and 330kg/m3 oven-dried basis respectively. Single-layer and three-layer particleboards of target densities 600. 700 and 800kg/m3 were produced using urea formaldehyde resin as binder. The strength properties and dimensional stability of these boards were determined and assessed for their relative compliance to Japanese Industrial Standard JIS A 5908-1994. These board properties were also compared with that of commercial particleboards. Blow-out problems were encountered for Enkabang jantong and Sentang at targeted board densities of 700kg/m3 and 800kg/m3 respectively.Most of the board fabricated met the minimum strength requirements for Type 13 of JIS except of Rubberwood and Sentang at 600kg/m3 board density. In terms of dimensional stability the thickness swelling values of these species were all below the maximum allowable limit of 12. Amongst the four species Acacia mangium boards processed the best strength properties and lowest thickness swelling. All the four reforestation species were assessed as potentially suitable raw material for particleboard production.
