The Effect of Weight Content or Density on the Burning Behavior of Some Cellulosic Specimens

The effect of different densities of various cellulosic specimens on their burning behavior has been of interest in this investigation. By using a vertical flammability tester, burning times of different unfinished cellulosic samples, such as white paper, straw paper, and cardboard, have been chosen and their flammability characteristics have been determined. The obtained figures for the consumed identical samples show that, by increasing their densities, their burning time and temperature of burning have been increased. However a decrease in the burning rate could rationally be attributed. Furthermore a decrease in the burning temperature proved a reasonable synonymy toward the decrease in the burning rate. In addition to this, burning rate is antithetical toward the density of the consumed specimens. A thermogravimetric analysis of a selected cellulosic material fortified our hypothesis; i.e., the thermal decomposition temperature differs from the burning temperature, whereas the latter temperature is merely dependent on the weight content or density of the samples.
