Effects of carbonization treatment on flame retardance and somke suppression of reconstituted bamboo.

Effects of carbonization treatment on flame retardance and somke suppression of reconstituted bamboo were investigated by cone calorimeter, oxygen index meter and smoke density meter. Results show that: carbonization treatment could decrease heat release rate (HRR) and mass loss rate (MLR) of reconstituted bam- boo, decrease total heat release (THR), increase oxygen index (L()l), and delay time to ignition (TT1). the peak of HRR (pkHRR) decreased by 36.6%, the time of reaching pkHRR was delayed by 450 s, TT1 increased by 5 times, L()l increased by 49.3 %, the peak of mass loss rate (pkMLR) decreased by 21.8%, and the time of reaching pkMLR was delayed by 505 s; carbonization treatment significantly decreased smoke produce rate (SPR), total smoke rate (TSR), smoke density rate (SDR), carbon monoxide release rate (COP) and carbon dioxide release rate(CO₂P) of the reconstituted bamboo. SDR of reconstituted bamboo decreased by 35.9%, time of reaching the maximum COP and CO₂P was delayed by about 600 s. Carbonization treatment had obvious effects on flame retardant and smoke suppression reconstituted bamboo. [ABSTRACT FROM AUTHOR]
