Ignition Properties of Thermally Thin Materials in the Cone Calorimeter: A Critical Mass Flux Model

Abstract

We describe a mathematical model to evaluate flammability parameters of thermally thin thermoplastics in radiative ignition experiments. The concept of a critical mass flux from the solid phase into the flame is used as the criticality condition. Kinetic parameter values are chosen by relating the Arrhenius parameters to the `characteristic temperature' that is measured in Thermogravimetric experiments. The specific application of our model we have in mind is piloted ignition in the cone calorimeter.

Keywords: cone calorimeter, flammability properties, thermogravimetry, thermoplastics .

Polymer Ignition

Abstract

We describe a mathematical model to evaluate the critical heat flux required to ignite thermoplastics in radiative ignition experiments. The concept of a critical mass flux from the solid phase into the gas phase is used as the criticality condition. Using this criterion, the solid temperature corresponding to the critical heat flux is related to the `characteristic temperature' determined in thermogravimetric experiments. We investigate the dependence of the critical heat flux and critical surface temperature on the value taken fro the critical mass flux. The specific application we have in mind is piloted ignition in the cone calorimeter.

Thermoplastics - The Effectiveness of Inert Additives in Reducing Flammability

Abstract

We describe a mathematical model to evaluate the retardancy effect of inert additives on the flammability parameters of thermally thin thermoplastics in radiative ignition experiments. The concept of a critical mass flux from the solid phase into the flame is used as the criticality condition for defining ignition. Kinetic parameter values are chosen by relating the Arrhenius parameters to the `characteristic temperature' measured in thermogravimetric experiments. The specific application that we have in mind for our model is piloted ignition in the cone calorimeter.
