QUESTIONS TO REDUCE THE RISK OF FIRE FIBREBOARD

Abstract

The work represents the result of the analytical review of theoretical and experimental research in the area of reducing fire hazard of wooden boards. Despite the large number of studies in this field some of its aspects remain unaffected, in particular, the reduction of fire hazard wood fiberboards of wet production method. The bulk of research devoted to the reduction of fire risk of chipboards and hardboard dry method of production. Technological solutions, acceptable for these industries are not suitable for the production of fiberboard wet method because of the specific conditions (high humidity) the occurrence of most manufacturing operations. In spite of the strong opinion that the introduction of wood-fiber plate only mineral fillers is ineffective, in 2013, was patented a composition for the production of fibreboard with reduced fire hazard. The patent was based on the results of research conducted in the Siberian state technological University A. V. Antonov, etc., However, A. V. Antonov, in his doctoral thesis work does not raise issues related to the process of grinding wood chips and fibrous semi-finished product. It is known that the quality of wood-fiber mass has a great influence on the quality of the finished fibreboard. In turn, the quality of wood-fiber semi-finished product is determined by the parameters of the milling process. Thus, the main direction of further research to improve the technology of production of fiberboard with a reduced fire hazard, from our point of view, is to develop a fundamentally new headset for knife grinding machines.
