Biological Resistance and Leaching Mechanism of Alder Camellias Prepared by Impregnation with Tanalith E and Celcure AC500

Due to the increase in the world population, the use of forest products has become widespread. However, meeting the increasing need for forest products without endangering the ecosystem will be the most important issue to be considered. In this respect, increasing the use of wood materials obtained from forests is among the subjects of interest of researchers. With this study, it is aimed to increase the useful life of the alder tree, which has a wide distribution area in our country, and to bring it to industrial areas. Alder (Alnus glutinosa) is abundant in the Black Sea region, but has no industrial value. Impregnated camellias obtained from Scots pine (Pinus sylvestris L.) wood, which is frequently used in industry, were used as reference product. Camellias prepared from alder and yellow pine impregnated with Tanalith E and Celcure AC 500 were exposed to the external environment. The biological strength of the samples (Coniophora puteana and Poria placenta) and washing mechanism were investigated. The rot test was carried out according to the EN 113 standard, the washing test was carried out according to the AWPA E11 standard. Washed water samples were subjected to copper analysis with ICP-MS device. According to the results obtained, the weight loss of the impregnated wood material in the rot test was much lower than the control groups. The lowest washing and copper rates were obtained from Scotch pine wood.
