摘要: The time evolution of the inhomogeneous curing process polystyrene emulsions is studied using a variant conventional photoacoustic (PA) technique. thermal effusivity, as function time, determined in order to monitor sintering styrene emulsion different steps manufacturing procedure. PA measurements effusivity show sigmoidal growth during process. parameterization these curves permits determination characteristic and velocity A decreasing an increasing for final are observed. feasibility our approach its potentiality characterization other discussed.
