Abstract
AbstractThe article is devoted to the actual problem of using industrial waste in order to obtain composite materials based on special chips with the addition of shavings-waste. The involvement in the processing of unused woodworking waste in full contributes to both expanding the raw material base for the production of composite materials and improving the environmental situation by reducing the negative impact on the environment. An analysis of domestic and foreign experience indicates the effectiveness of the use of cellulose-containing waste in the production of various composite materials. The article presents the results of studies aimed at testing the hypothesis about the possibility of using soft wood waste in the outer layers of board materials obtained using particle board technology. The experimental studies were based on a complete factorial plan, the results of which revealed the main regularities of the process of composite structure formation and obtained mathematical models of its strength properties in the form of regression equations. It has been established that with a specific pressing time of 0.25 min/mm, a temperature of 190 °C and the addition of waste shavings to the outer layers of board materials from 3 to 7% by weight, a material with a tensile strength perpendicular to the board of at least 0.35 MPa will be obtained and strength in static bending not less than 18.2 MPa. The results obtained can be recommended for use in the production of board materials with the required strength properties.KeywordsMachine shavingsParticle boardsStrengthStatic bendingStretchingRegression models
