Abstract

The result of laboratory tests on the properties of wood-woo/boards made from 17 wood species obtained from lrian Jaya are reported in this paper. The test comprised board density, moisture content, thickness reduction due to compression and bending strength.The study reveals that the average yield of wood-wool is 312 kg per cubic meter of log input.  The physical and mechanical properties of wood-wool boards from  five  wood species mineralized with CaCl2 solution or  Ca(OH)2 suspension are in compliance with the DIN 1101 standard.

Abstract

The  results  of  a  study on  the properties   of  wood-wool  board  made  from  tapped  and  untapped  pine   (Pinus  merkusii Jungh  et de Vriese)  is reported  in this paper.  The  wood  is obtained  from West Java.The result shows  that  hydration   temperature   of tapped  tree  is 36oC,  and untapped   pine  is  43°C. Based on this data, wood  from   tapped  pine  tree can be classified as medium  and that from  untapped  pine  as good  for wood-wool   board material. In general  the  wood-wool  board properties of  both  wood  sources  meet DIN standard.  The effect  of  tapping,  cement proportion, kind  of catalyst,  and interaction  between  cement  proportion  and kind  of catalyst  on the mechanical  properties of wood-wool board are significant.  Tapped pine  is better  than untapped  pine  as raw material for wood-wool board.

Abstract

The report  deals  with  laboratory  tests  on  the properties   of cement board  made  from   coconut husk bonded  with  Portland  cement. The test  includes  board  density,   moisture   content.   thickness reduction due to  and bending strength.The  result reveals that the physical   and  mechanical  properties   of  cement  board  made   with  Ca(OH)2 and K2SO4) Al2 (S04)3 mineralizing fluid produces  better  quality  board  compared with that using CaCl2. The physical  and mechanical  properties   of cement boards  with  Ca(OH)2 and  (K2SO4) Al2  (S04)3   conform   to  the  DIN 1101 standard. The bending  strength  of cement  board  made with CaCl2 does not conform  to the DIN 1101 standard.

Abstract

This report  deals with the  laboratory  tests  on  the  properties of  particle board made  from  coconut  wood  and from  coconut wood with  hardwood bonded by urea formaldehyde. The  tests include board density, moisture  content, water absorption, thickness swelling and bending  strength.The  result  reveals that physical and  mechanical  properties of  particle boards  made  from  coconut wood  conform with FAO Standard.  The  properties  of  particle boards  made  from   coconut  wood mixture  with  hardwood in  the proportion of  1 : 1 which conform the  FAO  Standard are limited to density and water absorption.

Abstract

The  experiment  result  of  using  sago  waste  for particleboard   is reported  in this paper.   The experiment  covers  the process   of   making   particleboard    with   several  raw  material  compositions    and   testing   their  physical   and  mechanical properties.   The  particleboard   is bonded   with  urea formaldehyde    resin with  the dimension   of  30 cm x  30 cm  x  1,5 cm,The  results  indicate  that  most  of  the physical  properties  of particleboard   meet  Indonesian  or FAO standards,  while many   of  mechanical  properties   do  not  meet  those  standards.  Veneer   lamination   improves  the  bending  strength  and  the addition   of  sago  bark  do  not  improve  physical   and  mechanical  properties   of  particleboard.
