(EN) COMPOSITIONS AND METHODS FOR PRESERVING WOOD PRODUCTS
(FR) COMPOSITIONS ET PROCEDES POUR LA PRESERVATION D'ARTICLES EN BOIS PAR IMPREGNATION D'ANTISEPTIQUE
Abstract
(EN)
Lumber, plywood and other wood products are preserved from attack by fungi, termites and wood-destroying insects as well as fire and flame by treatment with a novel zirconium borate-containing preservative composition. The preservative can be formed by combination of a source of boron such as boric acid and the water-soluble salts thereof with a water-soluble zirconium salt. The ZrO2:B2O3 weight ratio in the preservative composition is in the range of from about 0.75:1 to about 10:1.
(FR)
L'invention concerne un nouveau type de compositions d'imprégnation antiseptique à base de borate de zirconium pour préserver le bois d'oeuvre ou de placage et autres articles en bois contre les champignons, les termites et les insectes lignivores. On peut utiliser dans ce produit une combinaison à base de source de bor telle que l'acide borique, de sels hydrosolubles de cet acide et d'un sel de zirconium hydrosoluble. Le rapport de poids ZrO2:B2O3 de la composition considérée oscille entre 0,75:1 et 10:1 environ.
