Abstract

In this research, the FIXATION speed of 2% Celcure preservative (ACC) salt, under TEMPERATUREs of 17, 27 and 50°c, on intact and stained wood specimens of Beech was investigated. For this purpose, wood blocks of 5×5×7 cm dimension were prepared and saturated with 2% ACC using full-cell process. The specimens were placed in three incubators of the above-mentioned TEMPERATUREs. For measuring the percentage FIXATION through time, extracts of specimens were obtained, using hydraulic pressure of 69 Mpa. The pH of extractions was measured using DIPHENYL CARBAZID method and a SPECTROPHOTOMETER. Measurements were made continuously while the amount of 6-valency CHROMIUM present in the extract being compared with the amount of CHROMIUM concentration in the primary solution. The percentage FIXATION was then calculated. The results indicated that a decrease in 6-valency CHROMIUM is accompanied with an increase in pH, this being due to absorption of positive hydrogen ion by 6-valency CHROMIUM to be reduced to 3-valency CHROMIUM as well as ion-exhange of active components with wood during the primary phase of FIXATION. Time necessary for reaching complete FIXATION in intact and stained wood in the FIXATION TEMPERATURE conditions of 17, 27 and 50°c were 1075, 501 and 109 hours respectively. In general, it was shown that TEMPERATURE has an effective role in accelerating the FIXATION time, while in this process, intact and stained wood did not exhibit a significant statistical difference.
