Abstract

PURPOSE:To realize the stabilization of quality, the enhancement of productivity and the conservation of energy, by mounting a means for measuring electrical characteristics and means for controlling kneading until the measured electrical characteristics of an elastomer reach predetermined electrical characteristics. CONSTITUTION:When a substance having dielectric constant higher than that of rubber such as metal oxide or silicate is added to an elastomer, the impedance and electrostatic capacity of the elastomer vary corresponding to the addition amount of mixed and dispersed state of said substance. Therefore, by knowing the electrical characteristics of the elastomer during a kneading process, the mixed and dispersed state of the conductive substance such as carbon black or a metal power or high dielectric constant substance such as metal oxide or silicate in the elastomer, that is, the kneading advance state can be confirmed. The means for measuring the electrical characteristics of the elastomer during the kneading process and the means for controlling the kneading process until the electrical characteristics of the elastomer measured by the measuring means reach predetermined electrical characteristics are mounted.
