Title:
MIXING METHOD AND MIXING SYSTEM FOR RUBBER COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2016/021398
Kind Code:
A1
Abstract:
A mixing method and a mixing system for a rubber composition are provided with which unevenness in the temperature of a rubber mixture that is reached at the point of time when a carbon incorporation process is completed is reduced, thereby stabilizing the rubber properties. In each of steps of a carbon incorporation process and steps of a homogeneously dispersing process, at the point of time when the integrated quantity (S) of electric power required for rotating the mixing rotor(s) (2) has reached a predetermined integrated quantity of electric power, this step shifts to a next one. In the carbon incorporation process, the ram pressure (Pr) and/or the number of revolutions (N) of the mixing rotor(s) (2) is subjected to PID control on the basis of the difference between the temperature-rising rate of the rubber mixture (R) and a predetermined value thereof, thereby regulating the temperature of the rubber mixture (R) that is reached at the time of process completion to a value within an acceptable range. In each step of the homogeneously dispersing process, the ram pressure (Pr) or the number of revolutions (N) of the mixing rotor(s) (2) is controlled so as to reduce the difference between a value based on successively detected data on a given subject to be controlled and a predetermined value thereof.
