Influence of impregnation time on the degree of wood-based materials fire protection
Journal Title: Annals of WULS, Forestry and Wood Technology; Zeszyty naukowe SGGW - Year 2016, Vol 94, Issue
Abstract
The aim of the work was the determination of fire protection degree of wood-based materials (OSB, plywood), impregnated with a model fire retardant depending on the time the saturation. Was used 15% solution of fire retardant consisting of a mixture of potassium and guanidine carbonate. Samples were vacuum impregnated for 20, 40 and 60 min, followed by 2 h at atmospheric pressure. Research on the protection effectiveness was carried out by "french method". Test time was 20 minutes and was recorded time of ignition. After the test, were indicated parameters such as: the mass loss, depth and the surface of the burned area. Time to ignition of protected plywood was reduced, in contrast to the OSB. While the results for: mass loss, depth and surface of burned area, both OSB and plywood, have significantly improved in comparison with the control samples series.
