This paper used the TPS to measure the thermal conductivity of several different spray applied fire resistive materials between a temperature of 20-1000Ā°C. Mass loss and thermal strain were also investigated. These properties are crucial components of the material, and decide how effectively it will perform in the face of a fire. Temperature was found to have a significant impact on the thermal conductivity, mass loss and thermal strain. ...
An investigation was conducted to determine the thermal properties of different types of gypsum boards from the USA and Japan. The thermal conductivity and specific heat were determined at room temperature using the transient plane source technique. Measurements were first performed with the paper backing still on the boards, and then once the backing had been removed. Removing the paper resulted in a change in the specific heat, but the ...
This article studies the accuracy of using models to predict the mass loss of four polymers when they are exposed to fire like conditions. The researchers collected material property data; including density, thermal conductivity, reflectance and absorptance, heat capacity, and decomposition kinetics on each of the polymers. The TPS system is used to measure the initial thermal conductivity of the polymers. These measured values are put into predictive models for ...
Gypsum board is a building material that shrinks and cracks at high temperatures, which compromises the structural integrity of buildings during fires. Researchers in this study set out to determine the behavior of gypsum board when exposed to real fire conditions. A Thermal Constants Analyzer (TPS) measured the thermal conductivity of the gypsum board samples at and above room temperature using the transient plane source (TPS) technique. Results showed that ...
