PERUBAHAN SIFAT FISIK DAN STABILITAS DIMENSI KAYU AKIBAT PENGAWETAN MENGGUNAKAN IMPREGNASI KARBONDIOKSIDA
Abstract: The effect of
preservative treatment using carbon dioxide as a carrier solvent on wood
physical properties and dimensional stability had been observed on three
commercial wood species (Agathis sp., Palaquium sp., and Heritiera sp.). For
the purpose of the study, wood samples measuring 1,5 (R) x 1,5 (T) x 15 (L) cm
were prepared. Treatment was conducted at elevated temperature (50C - 350C) and
increased pressure (60 - 80 kgf/cm2) on one occasion with five replicates using
two specimens of each wood species for each treatment. The final treatment
condition was maintained for three different periods (10, 20, 30 minutes).
Results indicated that the physical properties and dimensional stability of the
preserved wood were not significantly affected by the application of CO2
impregnation as carrier solvent.
