Systematic review: Impact of processing parameters on dispersion of polycarbonate Composites, and pigment characterized by different techniques

Abstract

This paper provides a review on the impact of scanning microscopic methods to evaluate the influence of various processing parameters on the dispersion quality of the polycarbonate compound. Experimental data were compared with historical data records. The influences of parameters, pigment size distribution, and morphology on the pigment dispersion were also studied. The procedure consisted of dispersing the pigment using a co rotating twin extruder and then injection mold to produce colour chips; these were processed with three different parameters (temp, feed rate, and speed), at three different levels. The information on pigment dispersion were obtained using digital optical microscope (DOM), Scanning electron microscope (SEM), Particle size analyser (PSA), and Micro Ct Scanner (MCt)-image analysis. The optimum objective of this study is to evaluate pigment dispersion, by understanding the relation between the processing conditions, and the color difference output. This will help us in evaluation additional dispersion issues that have a bearing on color variations for different polycarbonate grades.
