The use of modified wood in the construction of wastewater treatment plants in coal mines of Kuzbass

Abstract

PurposeThe purpose of the study is to show an improvement in resistance (permeability) and durability (residual strength) of modified wood compared to natural wood.Design/methodology/approachA relevance way to increase the durability and resistance of wood is processing with polymers. Novosibirsk State Technical University, Novosibirsk State University of Architecture and Civil Engineering (Sibstrin) and the Norilsk State Industrial Institute researched the resistance of elements of mine treatment plants made of wood modified with synthetic polymers. The study was carried out according to V.A. Kucherenko. Modification of such species as birch and pine can significantly increase wood resources by extending its service life and improving its physical and mechanical properties. Latex-organosilicon modifier was used as a modifier.FindingsLatex clogs the capillaries of wood, preventing the penetration of aggressive solutions into it, and potassium methyl silicate interacts with hydrophilic OH groups, increasing the water-repellent properties of the surface of cells and wood capillaries.Originality/valueThe results of long-term and predictive tests of modified wood in aggressive environments of treatment facilities are presented. As a result, diffusion of aggressive media into the wood becomes more difficult and its resistance and durability increase.
