Evaluation of the aging wood from historical buildings as compared with the accelerated aging wood and cellulose -Analysis of color properties-
نویسندگان
چکیده
Color changes of wood during natural aging and during heat treatment were elucidated to determine whether they could be explained as the result of a mild thermal oxidation process at ambient temperatures. The results of kinetic analysis employing the time-temperature superposition method showed that the color changes during natural aging were mainly the result of an oxidation process. Color changes of heat-treated cellulose were also compared with that of wood and indicated that cellulose is responsible for the color changes of wood during natural aging and during heat treatment.

The color properties of aging wood samples from historical buildings have been compared with those of recent wood samples that were heat treated at temperatures ranging from 90 to 180°C. The results of kinetic analysis obtained by the time-temperature superposition method showed that the color change during natural aging was mainly due to a slow and mild oxidation process. In other words, heat ...

The synthetic polymers are widely used as adhesives, consolidants and protective coatings in the conservation of historic relics. Although, compared to the natural polymers and adhesives, these materials present a better resistance against the microorganisms, most synthetic polymers remain appropriate sources of Carbon and energy for the growth of microorganism; in addition, the relics consolid...

This paper describes the aging behavior of the oil impregnated repulped cellulose and compares it with the aging behavior of the oil impregnated standard cellulose. In order to evaluate the reliability of using repulped cellulose in transformers, the accelerated aging process was applied to both types of cellulose by increasing the temperature to 150 °C and their aging behavior was studied and ...

Characterization of structural woods in historical buildings has a great importance in technological study of applied details. Herein, seven historical buildings located in Alborz, Isfahan and eastern Azerbaijan provinces related to Safavid and Qajar periods have been assessed. Samplings were done from structural woods of the buildings. Samples were prepared, sectioned and evaluated by transiti...
