An Integrative Simulation for Mixing Different Polycarbonate Grades with the Same Color: Experimental Analysis and Evaluations

The processing parameters’ impact such as temperature (Temp.), feed rate (F.R.), and speed (S.) at three distinct grades of the same color was explored in this study. To investigate effect characteristics on formulations, they were each adjusted to five different levels. For these grades, which all associated with color, an intermeshing twin-screw extruder (TSE) used. compounded materials molded into flat coupons then evaluated a spectrophotometer for their CIE (L*, a*, b*, dE*) values. A used determine plastic batch, measured numbers indicating tristimulus values (CIE L*a*b*). lightness axis, ranged from 0 (black) 100 (white), is known L*-axis (white). Redness-greenness yellowness-blueness represented by other two coordinates, a* respectively. difference deviation (Delta E*) target dimensionless, when dE* approached zero. However, most excellent favorable value occurred factors polycarbonate grade investigated. Using response service design (RSD) software Stat-Ease Design-Expert® (Minneapolis, MN, USA), historical data gathered evaluated. reduce dE*, impacts investigated parameters. whole could be simulated.
