冲击混合是反应注射成型（RIM）工艺的独特特征，但混合头在很大程度上是通过试验和错误设计的。为了使撞击过程可视化，我们拍摄了高速照片。为了表征混合质量，我们遵循绝热温升的混合物，不同的雷诺数，混合头的几何形状和反应速率。这些结果进行检查的简化模型，其中包括流体力学和聚合方面的问题。
Impingement mixing is the unique feature of the reaction injection molding (RIM) process but mixheads are largely designed by trial and error. To visualize the impingement process we have taken high speed photographs. To characterize mixing quality we have followed adiabatic temperature rise of mixtures, varying Reynolds number, mixhead geometry and the reaction rate. These results are examined in terms of a simplified model which includes both fluid mechanical and polymerization aspects of the problem.
