Surface Electrochemical Study on the Fixation Properties of New Water-borne Preservatives in Red Pine

새로운 수용성(水溶性) 방부방충제(防腐防蟲劑)의 재중(材中) 정착성(定着性)에 관한 계면전기화학적(界面電氣化學的) 특성(特性)

In order to investigate the extent of fixation of new water-borne preservatives in blocks of pinus densiflora sapwoods the streaming potential through the column with preservative treated wood was measured at various conditions. The rates of leachability of ingredients in the treated wood were estimated by the measurement of electric conductivity of the solution with the leached components. The solution was also analyzed by Atomic absorption spectrophotometer (AA). As a results, the experimental data indicated that the fixation of CCB, CCFZ and ACQ in wood were relatively unstable. The fixation rates of CCB, CCFZ were improved by increasing heat and drying time. The amounts of the leached ingredients were apparently higher in CCB and CCFZ than in CCA, while the rate of leaching of ACQ was not changed at various drying temperature.
