The Moisture Content Effect on Full Cell Process of Bamboo Preservation.
[Project Paper Report]
Abstract
The retention, penetration and also the distribution
of CCA preservative in three different conditions (fresh,
partially dry and dry) of bamboo of Gigantochloa
scortechinii were studied.
The study also were done in different portions
(bottom and top) and different part of culms (inner and
outer) of bamboo. Treating process applied was full cell
process with one, two and three hours pressure period.
The results indicated that Preservative retention were
affected by moisture content and portions of the bamboo,
while preservative penetration only affected by moisture
content. The lower the moisture content the higher the
retention and the deeper the penetration of preservative.
Preservative solution enter the culms, besides from the
axial directions also from inner to outer part of the
culms. It makes the preservative retention in the\inner
part of the culms were higher than in the outer part.
Preservative penetration and retention in fresh bamboo,
even though lower than dry and partially dry bamboo but
can reach Malaysian Standard (MS.360:1986) for interior
purposes. Moreover the dried bamboo, where the moisture
content is below 15 % and part i ally dried bamboo, where
the moisture content are between 40 to 50 % can reach
Malaysian Standard for both interior and exterior
purposes.
