Specific Aspects of the Study of the Surface Properties of Plywood

Abstract:

Reducing the toxicity of plywood encourages the use of dry powder mixtures of polyester resin, as its dissolution in organic matter reduces environmental safety. The paper presents the results of studies of free surface energy and its components (polar and dispersed) for plywood, which is made on the basis of polyester resin. The sequences of polarity change and their ratio to the main component of wood after the formation of plywood board at high temperature, which are consistent with the structural and functional features of thermally modified wood. The resulting plywood is characterized by a reduced property of water absorption, because the free surface energy is reduced by 2.3 times and the polarity by 2 times, which is due to the thermal modification of the veneer. Thus, when applying a comprehensive approach to the study of wettability, polarity, interfacial tension, you can choose stable technologies for new wood products and expand its scope.
