MOOC - Rubber Technologist - Basic Level
Mixing Technology
This unit will elaborate on mixing technology for rubber compounds. Dispersion and distribution of fillers is no sinecure and is highly relevant for high performance applications. General mixing methodology and more in-detail mixing procedures and phenomena are treated.
Mixing of Silica & Silane compounds:
This element elaborates on special mixing approach required for Silica&Silane compounding, which takes several steps as Silica is hard to disperse due to the polar surface and should react with silane during mixing.
RUBTECHB.U4.E3.PC1
The student knows the general production procedure for Silica+Silane compounds, Silica/Silane coupling during mixing and Silane/Polymer coupling during vulcanization, and general mixing procedure for optimal processing
RUBTECHB.U4.E3.PC2
The student is aware of flocculation, thus degrading dispersion quality, during storage of ready-mixed compounds
RUBTECHB.U4.E3.PC3
The student has a basic understanding of Silica-Silane compound mixing and typical approaches to improve incorporation and reacivity of Silica and Silane
RUBTECHB.U4.E3.PC4
The student is able to explain the optimum dump temperature range by the Mooney viscosity vs. dump temperature graph for mixing
RUBTECHB.U4.E3.PC5
The student has a basic understanding of polymers extended with functional side groups on the backbone
