The influence of drilling patterns on the distribution of toxicants from Polesaver Rods in hardwood poles
1994 - IRG/WP 94-30051
Polesaver Rods are solid rods of wood preservative that are used as a groundline maintenance treatment to control biodeterioration in hardwood transmission poles in Australia. The rods are inserted in holes that are drilled in a prescribed manner to distribute the toxicants into the critical groundline region of the poles. To determine the influence of drilling patterns on the distribution of toxi...

A comparison of the diffusion of boron from two types of solid preservative rods into the heartwood of 3 Eucalypt pole species
2000 - IRG/WP 00-30227
The ability of boron to diffuse from polyborate and boron/fluoride rods through the heartwood of three eucalypt pole species (blackbutt, red ironbark and spotted gum) was examined. The aim was simply to determine the effects of rod type, wood species and time on the longitudinal diffusion of boron in eucalypt heartwood. Rapid diffusion of boron from polyborate or boron/fluoride preservative rods o...

Treatment of wood with boron esters
1995 - IRG/WP 95-30087
The treatment of wood and wood products with boron esters is reviewed. The physical and chemical characteristics of boron esters affecting the treatability of wood are discussed, in particular thermal decomposition and rates of hydrolysis. The uses and methods applying boron esters as wood preservatives include: (i) Solutions of boron esters for remedial and diffusible treatment of wood; (ii) soli...

Repairing of wooden elements by beta-method using carbon, steel or beech rods
2010 - IRG/WP 10-40488
Presented paper is focused on repairing of wooden elements by Beta joints reinforced with carbon, steel or beech rods, and on comparing the efficiency of these joints with traditional carpentry joints. In model laboratory experiments have been determined the bending strength (fm) and the modulus of elasticity (E) of control or original elements (fm-Control; Eo) from Norway spruce (Picea abies Kars...

Borate Redistribution in Glulam in an Above Ground Field Test
2014 - IRG/WP 14-30652
Researchers have refocused on the use of boratesin the wood protection industry in the last two decades due to their broad spectrum effectiveness against fungi and insects, and favourable environmental characteristics. This study was designed to determine borate distribution in a limited number of samples from a large field test of composites protected by a combination of coating and borate treatm...
