| Abstract: | The coating set is a device for applying the new and distinctive retarded adhesive material to prestressed concrete, through which the prestressed concrete strand is coated with retarded adhesive mortar in a polyethylene sheath successively. On the basis of analyzing the flowing and deforming characteristics of retarded adhesive mortar, the physical model of screw conveying is built. The retarded adhesive mortar's field of velocity and rate of flow in the screw is studied by using hydrodynamic kinedifferential equation with viscosity. It provides guidance and theoretical foundation for the set design and for the rational selection of running parameters. |
