Effect of Mixed Filler on Thermal Properties of Foodstuff Conveyor Belts Compound Using an Industrial Microwave Pre-Heating

Article Preview

Abstract:

This study presented the utilization of microwave power for heating of epoxidized natural rubber-50 compounding (ENR50c) with andwithout mixed filler in which the sulfur contents were 1.0, 1.5 and 2.0 parts per hundred parts of dried rubber by weight basis, respectively. The microwave power used was varied in a range of 340-1,700 W with a constant frequency of 2.45 GHz. The mixed filler significantly affected the relative dielectric constant, relative loss factor and loss tangent coefficient. The microwave power and time strongly influenced the temperature of the specimen. The longer time and higher microwave power resulted in higher temperature of the specimen. On the contrary, the thickness of specimen inversely affected the temperature of the specimen. The lower temperature was obtained from the thicker specimen.
