Abstract

This study has been carried out in order to be determined retention performance of boron compounds (Borax + Boric acid - wt:wt 50:50 %) and rosin (colophony) mixture used as impregnation material in wood materials. With this aim, test specimens which is made of Oriental Beech (Fagus orientalis Lipsky), Yellow Pine (Pinus sylvestris Lipsky) and Sessile Oak (Quercus petraea Liebl.) and prepared according to TS EN 212 have been impregnated with rosin and boron compounds mixtures that were produced according to the TS EN 212, with immersion method (ASTM D 1413). Impregnated test specimens were tested according to TS 345 and TS 6193 EN 84. Retention amounts after leaching processes of test specimens treated with solution boron compounds and rosin mixture were affected positively in Pine up to 243%, in oak up to 224% and beech up to 220% according to the retention amount after impregnation. Additionally, leaching ratios of test specimens were decreased in pine up to 45%, in oak up to 58% and beech up to 32% using this mixture according to the samples that were impregnated with boron compounds. Impregnation material did not affect of color, texture and brightness of experiment specimens in 3 different kind of woods too, any residue has not been observed on test specimens. Rosin and Boron compounds mixture can be preferred in forest industry for increasing leaching resistance in impregnation with boron.
