Dielectric properties of Hevea latex at various moisture contents

Kaida Khalid, . and Jumiah Hassan, . and W. Mohammad Daud, . Dielectric properties of Hevea latex at various moisture contents. pp. 172-189. ISSN 0127-7065

The dielectric properties of Hevea latex at various moisture contents at selected frequencies between 2.45 GHz to 18.0 GHz and at the temperature of 26C is reported. Measurement of the dielectric properties was done by using open-ended coaxial line sensor and automated network analyser with an accuracy of the measurement 5 for dielectric constant and 3 for dielectric loss. The results of the measurement are compared with the values predicted by dielectric mixture equations recommended by Weiner Bruggeman and Kraszewski. The study suggests that the dielectric properties of Hevea latex are mainly due to the orientation of loosely bound water molecules.

Abstract

The dielectric properties of Hevea latex at various moisture contents at selected frequencies between 2.45 GHz to 18.0 GHz and at the temperature of 26C is reported. Measurement of the dielectric properties was done by using open-ended coaxial line sensor and automated network analyser with an accuracy of the measurement 5 for dielectric constant and 3 for dielectric loss. The results of the measurement are compared with the values predicted by dielectric mixture equations recommended by Weiner Bruggeman and Kraszewski. The study suggests that the dielectric properties of Hevea latex are mainly due to the orientation of loosely bound water molecules.
