| Title of the article | Study of operational properties of cement-shaving boards based on thermally modified wood materials |
| Abstract. | The problem of the quality use of the wood and wood waste becomes more relevant both in Russia and in the world at the present time. Therefore, the development of resource-saving technologies for modifying of the properties of wood for the purpose of its further use in composite materials is an important task. Conducted research and the developed methods of thermomodification of wood for the possibility of its further use in composite materials with enhanced performance characteristics are presented in this work. The feasibility of using this type of processing in the manufacture of wood-cement composites to improve their operational characteristics is proved by results of researches of the influence of high temperature processing of wood raw material without access of oxygen: it is established that the preliminary high temperature treatment reduces significantly the content of «cement poisons» in the wood, the hygroscopicity and the development of swelling pressure and, consequently, allows you to create a composite material that is resistant to operation in conditions of high humidity. Thermal effect in the temperature range 483К raises significantly the operational characteristics of cement-shaving boards, while increasing its resistance. |
