Resolving material and processing issues is essential to improving formulations and attaining accurate color matching in blending. Two transparent polycarbonate resins made up the blend: PC1, which made up 33% of the mixture with a Melt Flow Index (MFI) of 25 g/min, and PC2, which made up 67% of the mixture with an MFI of 65 g/min. This study employed data mining and a well-structured experiment using Design of Experiment (DoE) software-8 to investigate the effects of various processing temperatures on identical material formulations. The primary objective was to understand the influence of the operating conditions on the viscosity of a red letdown pigment made of polycarbonate, both with additive (WA) and without additive (WOA). The study analyzed the effects of processing parameters and rheological properties using a co-rotating twin-screw extruder. Rheology, Fourier-Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscopy (SEM) were employed to compare results and evaluate their impact on minimizing color discrepancies and improving Single-Pass Color Uniformity.
解决材料和加工问题对于改进配方以及在混合过程中实现精确的颜色匹配至关重要。该混合物由两种透明聚碳酸酯树脂组成：PC1，占混合物的33%，熔体流动指数（MFI）为25 g/min；PC2，占混合物的67%，MFI为65 g/min。本研究采用数据挖掘和使用实验设计（DoE）软件 - 8进行的结构良好的实验，以研究各种加工温度对相同材料配方的影响。主要目的是了解操作条件对由聚碳酸酯制成的红色稀释颜料粘度的影响，包括添加添加剂（WA）和不添加添加剂（WOA）的情况。该研究使用同向旋转双螺杆挤出机分析了加工参数和流变性能的影响。采用流变学、傅里叶变换红外光谱（FTIR）和扫描电子显微镜（SEM）来比较结果，并评估它们对最小化颜色差异和改善单通道颜色均匀性的影响。
