A Study on Combustion Property of Cellulose Insulation according to Particle Size

The smouldering combustion of cellulose Insulation treated with boric acid - borax - aluminium sulfate as combustion retardants are examined by candle type combustibility tester. The flammability behavior of combustion process is LOI, Smouldering region, Smouldering, Flamming spread region and Flame spread region. In this experiment, Particle size of four examined LOI, L.Point, H.Point, at the biggest size show high LOI. The surface area is connected with thermal conduction. The phenomena of combustion transition are governed by quantity of combustible gas generation in heating zone of cellulose insulation.
