Abstract

The penetration of wood preservative of ten wood species from Lampung was studied. The obaervation was conduct- ed afier the timber had  been preserved by diffusion method. The BFCA 30% and wood •mples  of 6 cm by 10 cm by 200 cm were used in this experiment.The  results showed that wood .species  haB  significant effect  on penetration,  whi'le duration of  di/fusion storage period haB  the mme  effect  only on keruing, damar a8Clm,  balam and cengal banglai.Eight weeks of storage was better than 4  weeks on those timber,.  but not for the other species. According to IUFRO clasBifieation,pulai. kayu tabu and bintangur can be clasBifiedas permeable, while the others were classified aB  moderate

Abstract

Wood Samples of five species measuring 3 cm x 3cm x 3cm (200 samples for each species) were treated with cold soaking treatment using Wolmanil CB and Diffusol CB preservatives for 1, 3, 5, 7, and 9 days at the concentrations of 2, 4, 6, and 8 percent,The test result of experiment, after taking both retention and penetration requirements into concideration for wood used under roof, and in the open air both without ground contact, showed that only two species, perupuk and keruing daun lebar, could be satisfactorily treated with Wolmanil CB under the experimental conditions, while other three species, damar kunyil, lanan and dungun, haven 't been meet the standar. Diffusol CB preservative showed a good result only on one species, i. e. perupuk.Keruing daun lebar for under roof and in the open air usage both without ground contact can be consecutively soaked for 7 days in Wolmanit CB solution of 6 and 8 percent, while perupuk, only for under roof without ground contact, for 9 days in 8 percent solution. Perupuk used under roof and in the open air without ground contact could be soaked for 7 days in Diffusol CB solution of 4 and 6 percent.

Abstract

Wood samples  of three species measuring .3 cm x  3 cm x 3 cm (150 samples for each species) were treated with cold soaking treatment using borax and boric acid preservatives for 1,3,5,  7, and 9 days at the concentrations of 2,3, and 5 percent.The test result of experiment, after taking both retention and penetration  requirements into consideration for wood used under roof without ground contact showed that only  two species,  damar kunyit and pulai, could be satisfactorily treated with Boric Acid under the experimental  conditions,   while other species,  benuang,  couldn't  meet the standard.  Borax preservative  showed  a good result only on one species.  i.e.  pulai.For under roof usage without ground contact, pulai can be consecutively soaked for 9 and 7 days in boric acid solution of 3 and 5 percent, while in borax, for 5 and 3 days soaking  time are 3 and 5 percent. Damar kunyit used under roof without ground contact could be soaked for 7 days in boric acid solution of 5 percent.

Abstract

Five air dried timber species measured 2.5 x 5 x 10 cm was brushed by preservative in one of the broader side for four,  seven and ten times which similar with 1.25 g, 1.75  g and 2.25 g preservative.   The preservative  used  were Xylamon 5. 61  OC and  Cuprinol  118 L,  with the replication per  treatment were ten.  Two weeks after treatment preservative penetration  in all samples was measured.The  results  showed   that  the  preservative  penetration  of  all  treatment  did  not  mee trequirements for  timber housing. Additional brushing may be could improve penetration  and meet the standard but it will be costly. The cost offour,  seven and ten times brushing if appliedin door frame  are Rp  245,530,-  Rp.  343,742,-  and Rp.  44J,953,-  per  m3  with the price  of preservative Rp. 13,500,- per liter.Key words:  brushing,  Xylamon, Cuprinol, penetration

Abstract

Investigation about the cold-soaking treatment has been conducted on five wood species (i.e. keruing, nyatoh, melur, pulai and meranti merah) for housing purposes. The penetrating preservative for this case was CCB (copper-chrome-boron) chemicals. Before being treated. the wood specimens measuring 3 - 5 cm (in length) by 3 - 5 cm (in width) were prepared from each of the five species. Such specimens could not be treated by implementing the conventionally prescribed treating schedule. because the measurement of preservative retention at such schedule should follow the revised standard/schedule which differed from the conventional one. Hence, in cold-soaking treatment using CCB preservative, the specimens of wood species for such purpose had to be modified in their sizes/shapes.Three different sizes/shapes were prepared, i.e. beam, truss, and rafters; and then were allowed to reach their air-dry moisture contents. Afterwards. they underwent cold-soaking treatment using CCB preservative in two different concentrations (i.e. 5 percent and 10 percent). Meanwhile. the soaking durations implemented for each concentration were consecutively 3,5 and 7 days.The results revealed that all the wood species in all three sizes/shapes (i.e. beam. truss. and rafters)could be treated using the revised schedule. Except for meranti in truss and rafter. Related as such. the revised treating schedule for these five species has been appropriately devised.

Abstract

Three  Wood species,  i.e.  tusam  (Pinus  merkusii  Junh.  et De Vr.), karet  (Hevea brasiliensis Muell. Arg.) and jeungjing paraserianthes falcataria (L.)  Nielsen)   were  treated  with  two  bor preservatives  using cold soaking   method.  The  two preservatives  used  were  borax at  5  %  level  and  the  mixture  of  borax  and  boric acid  at  10  %  level.   The soaking periods  were  1,  3,  5 and 7 days. Forty  samples  of  the  size 5  x 5  x 50  cm  were  used for  each species  and  each treatment  in  thisn experiment.   The avemge moisture  content of the samples for each species  were 29 .9 %, 31. 9%  and 30.3% respectively.The results  showed   that  two species,  i.e. tusam  and karet  achieved  the  minimum standard on preservative  retention and pentatiue.   The  required  minimum retention for  borex  preservative  is 8. 7 kg/m3, whereas  for  the mixture of borax  and boric acid is 8.4 kg/m3.  The required  minimum penetration for both preservatives is 10 mm.The .study  recommended   that  tusam  should be treated in 5 days  using borax preservative  or  1  day  using the  mixture of   borax  and  boric,  both  with  cold  soaking  method.  The  treatment for  karet  was  recommended   to use the  mixture of borax  and  boric  acid  within 3 days.

Abstract

Moulding products made of two wood species in the form of coves were treated with BFCA preservative by cold soaking. The length of the test pieces were 30 cm. The duration of cold soaking treatment were 2, 4, 6 and 8 days, with preservative concentrations of 5 and 10 percent. The test results, after taking both retention and penetration requirements into consideration for wood uses under roof and in the open air without ground contact, showed that both wood species could be satisfactorily treated under experimental conditions. The treatment schedules proposed for both species are also presented in this paper. The average swelling of those species after treatment comparing to dimension are relatively small, therefore could be avaidable and has no affect on their use.

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.
