Leaching Characteristics of Copper in Copper Treated Wood
2003 - IRG/WP 03-30316
The leaching characteristics of copper in copper treated bamboo and other wood species such as slash pine and poplar has been conducted in this paper according to AWPA M11-87 standard, the result indicates that:
--Copper fixation rate of salts from organic acids such as citrate and oxalate and malate is less than other non-organic acid formulations.
--Copper fixation rate of oven-dried bamboo sa...

Isolation and identification of stain fungi and mould fungi on bamboo wood in China
2009 - IRG/WP 09-10703
One hundred and seventeen isolations were isolated from 150 specimens of mildewed or stained bamboo wood and bamboo products from 9 locations in north, south and central China. The molecular (ribosomal DNA Internal Transcribed Spacer, rDNA-ITS) and morphological identification results showed these fungi could be categorized 2 phyla, 2 classes, 4 subclasses, 10 orders, 15 families, 22 genera, 56 sp...

Laboratory test of some formulations against stain and mould fungi isolated from bamboo wood
2009 - IRG/WP 09-30508
To screen the effective anti-mould formulations, fungicides such as carbendazim, tebuconazole, fludioxonil, difenoconazole, prochloraz, benomyl and 8-hydroxy-quinoline copper (copper oxine) were selected to conduct the laboratory test of fungicidal activity by method of inhibition zone against Botryodiplodia theobromae Pat., Fusarium sp., Alternaria tenuis Nees., Penicillium purpurogenum Stoll, Tr...

Physical and Mechanical Properties of Bamboo Oriented Strand Board Treated with Copper-based Preservatives
2009 - IRG/WP 09-40482
Oriented strand board (OSB) has been gradually accepted, used and developed in China. Bamboo is a renewable and potential non-wood fibre resource for making OSB. But the nature of bamboo makes its products including bamboo OSB (BOSB) more prone to decay and mold. Protection BOSB from biodegradation is the key both to efficiently using bamboo resource and to improving the durability of the final pr...

The invasion channels of damage fungi in bamboo lumber
2010 - IRG/WP 10-10712
The micro-agents on bamboo lumber damage are mould, stain, and decay fungi. This research is about invasion channels of bamboo lumber damage fungi by scanning electron microscope (SEM). The results showed that the conidia of mould were only accumulated on the surface of bamboo and no hyphae detected in bamboo vascular bundle, and hyphae of stain penetrated into bamboo and grew in metaxylem vessel...

Effect of 4 Preservatives on Physical, Mechanical and Mold-Resistant Properties of Bamboo Oriented Strand Boards
2010 - IRG/WP 10-40483
This study investigated the effects of 4 preservative systems on physical, mechanical and mold-resistant properties of bamboo oriented strand board (OSB) panels bonded with urea formaldehyde resin. Preservative A (Zinc Borate), B (IPBC), C (AAC+Borate) and D (carbendazim + prochloraz) were incorporated with strands during blending at three loading levels. The results showed that the mechanical and...

End Coating Masson Pine Grown in South China to Prevent the Development of Blue Stain
2007 - IRG/WP 07-30428
One end (randomly selected) of logs of mason pine (Pinus massoniana) were coated with a wax-type end coating called ANCHORSEAL® immediately after tree cutting. The logs were then stored in summer weather in Guangxi, China. During the storage, at week 1, 2, 3, 4, 6, 8 and 12, five logs of mason pine were sawn into lumber or veneer for the visual observation and measurement of blue stain at the coa...
