Technical aspects of Coconut stem utilization
Technical aspects of Coconut stem utilization
Wulf Killmann
ABSTRACT
When processing the stem of the coconut palm (Cocos nucifera L), various aspects have to be taken into consideration in order to achieve satisfactory results. Sawing and handling: remove stems from the plantation immediately after felling and convert them quickly - use tungsten carbide or stellited saw blades - apply large bites as recommended for hardwood - maintain saw properly - dip the timber in fungicide after sawing - segregate and stack the sawn timber in accordance with at least two, preferably three density classes - Seasoning: air season the timber properly stacked (in airy place under cover, off the ground, with fillets between) - air dry timber down to 30% before kiln drying it do not dry batches of mixed densities. Preservation: all timber In exterior use and/ or with ground contact
should be (preferably pressure) treated for pressure treatments, the material should be dried below fiber saturation point logs for power poles have to debarked and then dried under shelter at least 4months before treatment. Utilization: choose carefully timber of right
density for the product envisaged.
