Industrial Implementation of the Integrated Continuoius Mixing iCOM®
To achieve an optimal production process VMI Holland BV and Rhein Chemie Rheinau GmbH have developed the iCOM®-process . In this process the final mixing of the base compound together with the vulcanization system can be performed in a single production step. Additionally, the compound can be screened by using a gear pump strainer combination. The vulcanization system is added in form of a polymer bound additive package. Due to the pre-dispersion of the powdered additives and the immediate incorporation of the granules a homogeneous final compounds with a high quality is produced at reasonable output. The process safety is guaranteed by the inline quality process control Rhenowave® . Rhenowave® uses ultrasonic waves to measure the distribution of the crosslinking chemicals with zinc oxide as a marker substance. In addition Rhenowave® provides information on the amount and the dispersion of fillers in the compound.
Rhein Chemie Rheinau GmbH has set-up two extrusion lines for the production of bladder compounds using the integrated continuous mixing process iCOM®. The feasibility of the iCOM®-process at large scale is demonstrated using the inline process control Rhenowave®. In addition to that Rhenowave® can be used in many other applications to determine the quality of various rubber compounds.
