| Résumé : |
The success of mixing in extrusion and the product homogeneity are often only assessed optically based on individual experience. A new characterization process now permits the color distribution to be assessed objectively using clear criteria. It allows the mixing quality of extrusion systems to be assessed for different polymers and process parameters. |
| Note de contenu : |
- Non-uniformly distributed color-particles or fillers
- Method for assessing the mixing quality
- Algorithm for evaluating the sample images
- Experiments with extruded plastics
- Summary : Evaluation based on objective criteria
- Fig. 1 : Diversity of color requires flexible production changeover : wire and cable insulation in several different product or color variations can be manufactured on a production line by the addition of masterbatches
- Fig. 2 : Reference images for classifying the extrudate homogeneity in nine classes
- Fig. 3 : Error distribution according to Floyd-Steinberg : distribution of the error in the binarization from pixel 1 to pixels 2 to 5
- Fig. 4 : Bayes weighting of the neighbors of an average pixel
- Fig. 5 : Number of same-colored neighboring points for the color white : distribution span and maximum
- Table 1 : Homogeneity analysis of selected thin sections |
