Abstract

A full cell treatment of four wood species with 5 and 7 percent copper-chrome-arcenic solution  was conducted using small samples  of 18-25 cm in diametre and 30 cm long. The cross cut-ends of the samples were coated to prevent penetration of the preservative  through  these parts. The preservation  process were held for 2 and 4 hours at a pressure  of 8 and 10 atmosphere.                                                                 The result of the test revealed that four wood species (keluntum, medang, manggung   and  puspa) are recommended for  power poles servation. The treatment shchedule  proposed  for four wood  species  is presented in this paper.

Abstract

The result of cold soaking treatment of ten wood species is reported  in this paper.  Five wood  species are recommended  for housing (agatis, balsa, damar kaca, karet  and  kemayau), whereas  the  other  five  species  (begontoi, belangeran, kenari I, kenari  II and  mahoni) could  not  meet  the  spesification. Solution concentration of Koppers  Formula  7 preservative  used  was 10  percent  with  soaking period  of one, three and five days. The treatment  shchedule  proposed  for five  wood species  is also presented in this  paper.

Abstract

Five wood species Shorea hopeifolia Sym; Palaquium ferox H.J.L.; Dillenia eximia Miq; Hopea sangal Kortn.; Tristania maingayi Duthie treated with copper-chrome-arsenic (CCA) preservative, were studied using the full cel process. The treatments comprising concentration, pressure, and pressure period, and the responses are penetration and the retention of preservative.
