THE BREAKING DOWN AND AGGLOMERATING OF FILLERS IN POLYMER MELT - A PHYSICAL MODEL FOR MATHEMATICAL-DESCRIPTION

The filling and reinforcement of polymers represents an essential proc ess task in manufacturing technology. For this reason, in the course o f working in the filling ng substances, the distribution should also b e accompanied by a break down of agglomerates. A description of the di spersion process during manufacture is of great importance for the des ign of process zones in a production machine. In addition to the basic principles, a mathematical description of the dispersion of additives in a polymer melt will be presented. Here, because of the complexity of the dispersion process, the form of the model assumes simple physic al theorems for description of the problem. This procedure leads to a description employing mathematical relationships, with the help of whi ch the agglomerate size can be calculated in relation to material and process values.
