MODIFICATION OF WOOD WITH ENVIRONMENTALLY CLEAN MATERIALS

Abstract

The publications of Ukrainian and foreign researchers on this issue in recent years have been analyzed in detail. The purpose ofresearch is to analyze environmentally friendly materials of the oil type (linen, tung, tar, mineral, etc.) as a safe way of reliablemodification of wood. An analysis of wood modification with natural, environmentally friendly materials was carried out. The process of modification (chemical, physical or biological) of wood involves improving the quality of the material due to the improvement of a number of properties - resistance to decay, changes in geometric dimensions, exposure to atmospheric influences, improvement of mechanical properties, etc. The physical method of improving the quality of wood by the method of impregnation has been studied. It has been established that solutions based on oils and resins are used to impregnate wood with the addition of components that accelerate their polycondensation and contribute to changing properties. The impact of different types of natural oils (wood, teak, tar, linseed, tung oil) was analyzed, their positive and negative properties were takeninto account. The advantages of natural oils are their natural origin and environmental friendliness. In addition, the properties of mineral oils, which are produced from oil through long-term multi-stage purification, have been determined. In the future, it is necessary to conduct experimental and theoretical studies of wood modified with natural materials in various ways. To propose the main progressive methods of modifying wood with natural, environmentally friendly materials. In the future, establish the main mechanical properties of the obtained materials under the influence of various aggressive environments, in particular strength and deformation indicators, including the initial modulus of elasticity. Also offer a theoretical rationale for the future results.
