Abstract

A study on the treatability of eleven wood species was carried out using hot and cold soaking  treatment  methods  with Koppers Formula  7 as preservative. Specimens measuring 50 cm x 5 cm x 5 cm were soaked  in five  and ten percent preservative  solution for  a duration  of one, two, and three hours and then allowed to cool while the timber is still soaked in the liquid.  The penetration  and retention  were recorded. From this study  the following   conclusions  could  be drawn:The treatment schedule and concentration  of solution  have a highly significant  effect  on the preservative  penetration  and retention. Much higher retention  was shown  when longer hot soaking  and higher concentration  were employed.

Abstract

Impregnation    under  pressure  is  the  most  effective  way  of  applying  preservative   to  timbers,   but  not  all species can be treated  effectively  using  the  method.   Air-dried  timbers  of  5 cm  x  5 cm x  100 cm in dimension   were impregnated   with preservative   used  for  constructional   purposes.   Part of  wood  samples  was presteamed.   Prior to  the preservative   treatment both  groups  were reconditioned    to  the same  moisture  content   as the  reference   material  (air dried).Retention  and  penetration   figures  have  increased as presteaming   was applied.   The  result revealed  that  two  timbers preserved   met   the  standard   requirement.    The  preservation   schedule  proposed   for  the  timbers  is presented   in this paper.

Abstract

Fifteen  wood species from  Irian  Jaya  with sample  test pieces  measuring  5 x 5 x  60 cm,  and  water content  from 20. 0-21.4 percent, were subjected  to cold soaking  treatment,  using 5 and 10 percent  concentration  of BFCA  preservative,  for  three, five  and seven  days. Taking into account  the penetration  and retention  requirement for  wood use condition  under roof and outdoor,  without ground contact,  the result indicates that matoa  wood could not be treated  with the schedule proposed  in this paper.  The other fourteen   wood species could be treated with any of the treatment schedule (Table 4). However,  two species (honggimako  and senai) meet only the requirement for  use under roof  without ground  contact.

Abstract

The  paper  deals  with  an experiment    of  alternating  pressure  method   on  three  wood  species  with  borax.    The  green wood  samples  were  impregnated   with  three percent   borax  solution.   The  results  of  experiment    are as follows  :1.  Wood species  and  treatment   schedule  show  non  significant    effect   on  boron  penetration     and  retention.2.  In  general  the  impregnation  of   the  green  wood  results  in  variable  treatment   and  limited  penetration   and  retention.3.  Retention  and  penetration    showed   better   figures  when  only   modifying    the  treating  cycle   rather  than  using  a  pretreatment.
