摘　　要：依据两相流理论,对盘式热分散机胶粘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粘物在热分散过程中的受力状况.研究结果表明:在浆料流动过程中,由于流相对固相的阻力以及固相在流动中的加速度力的作用,使粘附在纤维上的胶粘物从纤维上剥离,并分散成细小颗粒.Based on the theory of two-phase flow, the disk thermal dispering mechanism and influence to stickies was analyzed in this paper. The force between fibers and stickles was focused on when the disk was working. The results showed that stickles were peeled from fibers and dispersed into small particles during the flowing procedure of the pulp, which can be contributed to the force applied on liquid phase by the solid phase and the acceleration force produced by the flowing solid phase.
