Resumen
THIS PAPER REPORTS ON THE PROPERTIES OF PINUS RADIATA WOOD IMPREGNATED WITH AN ORGANIC PHASE CHANGE MATERIAL (O-PCM). THE TESTS ARE AIMED AT CHARACTERIZING THE KINETICS OF IMPREGNATION (RATES, FLOWS, AND FRONTS) AND THE THERMOPHYSICAL PROPERTIES (THERMAL CONDUCTIVITY AND SPECIFIC HEAT). IN PARTICULAR, A PARAFFIN TYPE O-PCM (OCTADECANE) IS USED TO IMPREGNATE DRY RADIATA PINE WOOD IN THE TANGENTIAL FLOW DIRECTION AT FOUR MANOMETRIC PRESSURES (0, 1, 2, AND 3 BAR) AND CONSTANT TEMPERATURE OF 50 °C. THE WOOD IS SAPWOOD FROM 12-YEAR OLD P. RADIATA GROWING IN THE BÍO-BÍO REGION AND DIMENSIONED ACCORDING TO CHILEAN STANDARD FOR TREATED WOOD SAMPLE EXTRACTION. THE RESULTS SHOW THAT IT IS VIABLE TO IMPREGNATE P. RADIATA WOOD WITH O-PCM TO IMPROVE ITS THERMOPHYSICAL PROPERTIES WITH THE PURPOSE OF PASSIVE CONDITIONING.
