摘　　要：依据两相流理论,对盘式热分散机胶黏物分散作用的机理进行了研究。重点分析了盘式热分散机工作时纤维与胶黏物在热分散过程中的受力状况。结果表明,在浆料流动过程中,由于液相对固相的阻力以及固相在流动中的加速度力的作用,使黏附在纤维上的胶黏物从纤维上剥离,并分散成细小颗粒。Based on the theory of two-phase flow,the dispersion mechanism of disk dispersers was investigated. The study focused on the analysis of stressing states of the fiber and stickies when the disk disperser was in operation. The result showed that stickies are peeled from fibers and then dispersed into small particles. Due to the resistance applied to fluid by the solid phase and the acceleration force produced by the flowing solid phase.
