Technological scheme of wood resources utilization model development

Abstract

In the present work the justification of the urgency of solving the issue of environmental friendliness of materials produced from wood resources is given. The analysis of the production technology of semifinished wood-fiber products is carried out at the current stage of development of the board industry. The estimation of board formation properties of the wood fiber mass produced in disk blade grinding machines is given, and the inefficiency of the used equipment is substantiated. The expediency of using the equipment with cavitation effect as the second grinding stage in the production of wood pulp was substantiated. As a result, the purpose of the present work was the development of the technology for the production of the semifinished wood fiber product with the use of a rotor-pulsation apparatus as the second stage of the wood pulp mill. To achieve the goal, an analysis of modern technologies used in the production of fiberboard was carried out. The model of technological scheme of production of wood fiberboards by wet method in the environment of AnyLogic program package was developed. Based on the technological scheme developed, a dynamic model of the fiberboard production process was built using a rotor-pulsation apparatus in the second stage of wood pulp milling. In the course of research, statistical analysis methods and simulation modelling of technological processes were applied. The results obtained can find application in the production of fiberboard, as well as in the improvement of technological processes at the enterprises of the forest complex.
