Slurries are used across various industries, with particle dispersion control being crucial for optimizing product properties. The kneading process, involving high particle concentration kneading followed by dilution, is known to enhance particle dispersion in the production of electrodes and paint. However, not all industries that optimize product characteristics through particle dispersion control in slurries adopt the kneading process. This study analyzes the impact of kneading conditions on slurry properties, using carbon slurries as a case study to elucidate its true effects. Our findings revealed that as the particle concentration increased during kneading, particles exhibited behaviors such as “dispersed,” “aggregated,” “dispersed and then aggregated,” and “unchanged.” Traditionally, kneading has been viewed as a method to promote particle dispersion. However, this study highlights the need for a renewed understanding of kneading effects, challenging the conventional perception of its role in affecting particle dispersion.

捏合过程中颗粒浓度对碳浆颗粒分散状态的影响


浆料用于各个行业，颗粒分散控制对于优化产品特性至关重要。众所周知，捏合过程包括高颗粒浓度的捏合，然后进行稀释，可以增强电极和油漆生产中的颗粒分散。然而，并非所有通过浆料中颗粒分散控制来优化产品特性的行业都采用捏合工艺。本研究分析了捏合条件对浆料性能的影响，以碳浆为案例研究来阐明其真实影响。我们的研究结果表明，随着捏合过程中颗粒浓度的增加，颗粒表现出 “分散”、“聚集”、“分散后聚集” 和 “不变” 等行为。传统上，捏合被视为一种促进颗粒分散的方法。然而，这项研究强调了重新理解捏合效应的必要性，挑战了对其在影响颗粒分散中的作用的传统看法。
