The process of impregnation the barite chemical in the wood and its effects an some technological features

Inthisstudy, Larex deciduamill wood's barite and boroncomposites different concentration (1%, 3%, 5%) impregnating with respectto ASTM 1413-76 standards and thechanges on technological features ar eresearched. Total retention, retention percent, total-dry air specific bulk density, bendingrigidity, resilience, compressives trength, adhesions trength and other physical characteristicsare determined. According to the results of experiments, the seare obtained; The most total-dry air specific bulk density is 5% Barite+Ba (0,62 g/cm3), is obtained at dry air specific bulk density 5% Barite+Ba (0.65 g/cm3). In mechanical features; the most bendingrigidity is 1% Boric Acid (145 N/mm2), the most resilience is 1% Boric Acid (17243 N/mm2), the most compressives trength is 1% Boric Acid (80,49 N/mm2), the most adhesions trength is 1%Barite (12,13 N/mm2). With respect to wood - water relation based on hours, the least contraction in 6 hours at 1% Borax (Bx) is 7,13%;expansion value in 6 hours at 1%Borax is (6,17%).
