The probable mechanism of action of boric acid and borates as wood preservatives
1990 - IRG/WP 1450
The tetrahydroxyborate ion [B(OH)4-] acts by complexation with poly-ols and probably attacks decay fungi through extracellular substrate sequestration; intracellular substrate sequestration; enzyme inhibition; and change in membrane function. Work was carried out to investigate this further and to try to explain certain phenomena observed in the area of boron preservation. The effect of Na borate ...

The effect of of sorbitol on the decay of boric acid treated Scots pine
1991 - IRG/WP 1509
The tetra-hydroxy borate ion is known to undergo complexation with polyols of biological importance and probably protects treated timber by this action. The inhibitory effect of boric acid upon fungal growth and dehydrogenases has been shown to be prevented by the addition of certain polyols. This work was extended, with a study of the effects of a polyol on the performance of boric acid in treate...

Liquefaction of woody waste: A novel approach in wood protection from CNSL based liquefied wood polyols
2017 - IRG/WP 17-30711
Liquefaction of lingo-cellulosic biomass is one of the thermo-chemical conversion processes for developing new materials, adhesives, preservatives and energy systems. The process also provides an opportunity to utilize waste wood such as saw-dust, woody wastes, branches and twigs for the development of value added products. Thus, this research paper deals with an investigation of antifungal and a...

Liquefied wood polyols: Ecofriendly bio-based preservative for sustainable protection of wood from Termite attack
2018 - IRG/WP 18-10916
The major problems encountered in both indoor and outdoor utilization of wood are biological decay due to termite. The modification of wood with liquefied wood polyols has been found to be effective against termite attack. The liquefaction of wood aims to utilize woody wastes which are being generated during primary and secondary processing of wood in wood based industry. One of promising approach...

Liquefied wood polyols: a bio-based preservative for protection of wood from fungal decay
2018 - IRG/WP 18-30725
The liquefaction of wood is one of promising approaches in utilization of woody waste which is generated during primary and secondary processing of wood and liquefied wood having various application including bio-based preservatives. The biological degradation of wood due to fungi is the major problem encountered in indoor and outdoor utilization of wood. In this study, woody waste recovered from ...

Novel approaches for improvement of dimensional, photo- and thermal stability of wood through liquefied wood polyols impregnation
2019 - IRG/WP 19-40884
The major problems encountered in both indoor and outdoor utilization of wood are due photo instability and dimensional instability. The modification of Melia dubia wood for ultraviolet resistance and dimensional stability with liquefied wood has been carried out through impregnation method under solvent free conditions. The level of impregnation in modified wood was estimated by weight perc...
