INFLUENCE OF CLIMATIC AGING ON OPERATING PROPERTIES OF FIBERBOARD

Abstract

Statement of the problem. The objective of the study is to reveal the influence of climatic factors (heat aging, UV irradiation, humidity) on the performance of fiberboard. Results. The results of experimental studies of the operational properties of fiberboard exposed to moisture, heat aging, and UV radiation are presented. The research results are based on the main provisions of the thermal fluctuation theory. Conclusions. The set of studies carried out sufficiently demonstrates the effect of climatic aging on the performance properties of fiberboard. During research, it was revealed that climatic aging has a detrimental effect on fiberboard, namely, the bonds between the filler particles are broken, because of which there is a complex decrease in the strength and resistance of the material to other climatic influences.
