Ismail Jusoh, . and Kamdem D . P ., . Penetration and retention of CCA in rubberwood (Hevea brasiliensis). pp. 77-84. ISSN 1394-2204
Abstract
Rubberwood is very popular for making furniture since rubberwood is relatively abundant sustainable and cheap. Currently more than 60 percent of the annual total rubberwood produced by rubber plantations is used as fuelwood. Rubberwood has the potential for both indoor and outdoor uses. For exterior applications preservative treatment is needed in order to extend its service life. Quarter-sawn rubberwood sample blocks measuring 35 x 35 x 125 mm were sealed with SCS 1200 GE silicon rubber adhesive sealant to permit preservative penetration in only one or two directions. Sets of blocks were pre-treated with stem prior to sealing. The treatability of rubberwood was evaluated by measuring CCA type C preservative penetration and retention after full-cell treatment. Longitudinal permeability was found to be greater than transverse permeability. In transverse direction variation in permeability was observed. The penetration and retention in the radial direction were about three times better than in the tangential direction. Longer pressure period increased penetration and retention of CCA type C in rubberwood. Complete penetration was achieved after 4 h of pressure treatment. Pre-treatment steaming improved the treatability of rubberwood regardless of the anatomical direction.
