Abstract
Wood is widely used in various industries. However, the inherent ability of natural wood to absorb water and other disadvantages require its modification with various compositions. In the work, the technology of impregnation of birch wood with processed vegetable oil, which remains after cooking, has been studied. Impregnated composition was introduced into pre-prepared wood using the “hot-cold baths” method and subsequent heat treatment of wood impregnated with used sunflower oil. The influence of the main quantitative parameters of the impregnation process on the performance of wood specimens have been made using the design of the experiment according to the Greek-Latin square pattern of the fourth order. The influence of the temperature of the impregnating oil, the time of impregnation, temperature and the duration of the heat treatment on the properties of modified wood has been studied. The properties of birch wood has been evaluated by its water absorption, as well as swelling of specimens in the radial and tangential directions. The regression equations have been obtained. They describe the influence of the main parameters of the impregnatio process with processed sunflower oil on the properties of modified wood. The best conditions for introducing processed sunflower oil into wood have been established. The proposed impregnating composition improves decorative properties of wood. It is odorless and environmentally friendly. It has been shown that treating birch wood with processed vegetable oil makes it possible to obtain modified wood with increased resistance to water
