Visualization of inorganic element distribution in preservative treated wood by SEM-EDXA
2001 - IRG/WP 01-40208
SEM-EDXA was found to be an effective way of visualizing inorganic element distribution in wood as it was possible to examine some inorganic elements at the same time and map the concentration differences in color. Japanese cedar sapwoods were impregnated by vacuum treatment with CuAz or by pressure treatment with CCA preservatives and then distribution of Cu, Cr and As elements in wood were exami...

Anatomical Characteristics to the Distribution of Water-borne Copper Wood Preservatives in Wood
2004 - IRG/WP 04-40277
The objective of this study was to understand the micro-distribution of a copper-based preservative in wood in connection with anatomical morphology and to consider the fixation of copper in wood. Bulk specimens and semi-ultra thin sections (0.5µm) obtained from Japanese cedar were treated with a CuAz preservative solution. After fixation, SEM-EDXA was used to investigate the micro-distribution...

Tendency of the preservative use for impregnation industries in Japan
1998 - IRG/WP 98-50101-05
In Japan, since 1997, the acceptable limit of the arsenic in the waste water become to 0,1 mg/l and the additional regional severer restriction can be established. In this reason, Japanese wood preservation industries intend to use other than CCA, like DDAC, ACQ, Tanalith CuAz, copper-naphthate and zinc-naphthenate, as replacing from CCA. In Jan-June 1997, the share of CCA preservatives was less t...

Wood decay fungi from New Zealand ‘leaky’ buildings: PCR identification and laboratory decay tests of wood preservative-treated Pinus radiata (Part 1)
2007 - IRG/WP 07-10620
Fungi colonising Pinus radiata D. Don framing timber of ‘leaky’ New Zealand buildings were isolated to produce pure cultures. Mycelia from these cultures on agar media were collected to extract DNA. To identify the fungi to the species level, polymerase chain reaction (PCR) with primer pairs ITS1-F and ITS4 were performed followed by sequencing of the internal transcribed spacer (ITS) region. ...

Field trials results of preservative treated ground contact stake conducted in Korea
2014 - IRG/WP 14-30640
The field trials results from Korea preservative treated ground contact stake are reported. There was two site which was in southern area(Anmeon) and east area (Jungsun) of Korea. The CUAZ, CCA and CBHDO preservatives were use in this study. The sapwood of Japanese red pine stake was treated with these preservatives according to Korea standard method and then installed in 2003. Every year the insp...

Evaluation of Decay Resistance of Copper-based Preservatives Treated-Wood exposed to different field test sites in Korea
2022 - IRG/WP 22-20679
In Korea, preservative treated wood is required to have a stamp on the surface which contains information such as wood species, use categories, and the company that treated the wood. Such stamping is necessary to safely and appropriately use the treated wood. Since majority of treated wood is being used outdoor environment, the treated wood must have efficacy against wood decay fungi or termite. I...
