摘要

为研究切向速度对微粒材料系统沉积的影响，特别是对乳胶微粒的影响，测试了流体加热纺丝盘设备（SDA）的适用性。首先，以微型玻璃珠为模型系统对 SDA 进行了颗粒堵塞研究，然后，以醋酸乙烯酯/Versa 10 共聚物为真实材料系统进行了第一轮测试。实验持续了 1 小时，切向速度达到 0.3 m s-1。污垢过程的特征是局部污垢层厚度和计算得出的局部质量污垢阻力。观察到污垢阻力沿旋转盘半径的下降与切向速度成函数关系。

Applicability of a Spinning Disk Apparatus for the Investigation of Particulate Fouling

The applicability of a fluidically heated spinning disk apparatus (SDA) was tested for investigating the influence of the tangential velocity on the deposition of particulate material systems, in particular on latex particles. First, the SDA was characterized for particle fouling investigations with micro glass beads as a model system, then, a first series of tests was carried out with a real material system, a vinyl acetate/Versa 10 copolymer. Experiments were performed for a duration of 1 h and a tangential velocity up to 0.3 m s⁻¹. The fouling process was characterized by the local fouling layer thickness and the calculated local mass-based fouling resistance. A decrease in fouling resistance along the radius of the rotating disk as a function of the tangential velocity was observed.
