Note. Ti is the ignition temperature; T1, T2, and T3 are the reaction peak temperatures of the first, second, and third peaks; Th is the burnout temperature; Rmax−1, Rmax−2, and Rmax−3 are reaction rates corresponding to T1, T2, and T3; Rmax is the maximum reaction rate; Rmean is the average combustion rate; C is flammability index; and S is the comprehensive combustion characteristic index.
