Properties of wood-wool board manufactured from 19 wood species from central Sulawesi.
The results are reported of laboratory tests on the properties of wood wool boards made using CaCl2 and Ca(OH)2 as catalysts. Data tabulated include: log and wood wool board dimensions; specific gravity, m.c. and wood wool output of logs; and board m.c., density, thickness reduction due to compression, and bending strength. Av. output of wood wool was 238 kg/m3 of log input. Four species (mangga hutan, Mangifera foetida; kirontasi, Ailanthus malabarica [A. triphysa]; eboni, Diospyros macrophylla; and mangga, Mangifera minor) required presoaking. The physical and mechanical properties of boards from 7 species (bugis, Koordersiodendron pinnatum; bayur, Pterospermum celebicum; enei, Haplolobus celebicus; nyatoh I, Palaquium obtusifolium; nyatoh II, Palaquium obovatum; bintangur, Calophyllum soulatri [C. soulattri]; and eboni), mineralized with CaCl2 or Ca(OH)2, met the DIN 1101 standard. The other 9 species tested were: buniyaga, Drypetes longifolia; palapi, Tarrietia [Heritiera] javanica; kedondong, Spondias cytherea; dahu I, Dracontomelon mangiferum; dahu II, Dracontomelon dao; benuang, Octomeles sumatrana; durian, Durio zibethinus; meranti, Shorea koordersii; and kalaka, Parinari corymbosa.
