Effect of dehydration of gypsum board used in multilayered fire resistant structure
Santrauka
This article analyses influence of gypsum board’s dehydration effect on thermal behaviour of multilayered mechanical structure (fire door). The surfaces of mechanical structure were heated in furnace for specified periods of time of 60 min. Results are presented as temperature-time plots. The experimental results were verified numerically. The data obtained allows to calculate convection coefficient of gypsum board fitted in multilayered structure.
