Abstract
The invention discloses a twin screw for controlling a flame-retardant polypropylene material to be decomposed in a machining process. The twin screw comprises a twin screw body which is meshed with a twin-screw extruder in the same direction, wherein according to a screw combination of the twin-screw body, a stretching block is arranged on a melting mixing section of the twin screw body with a general screw combination and/or a toothed wheel disk is arranged in front of a metering section. The stretching block is arranged on a melting section of the twin-screw body, so that the distribution and dispersing capacity of the screw is improved, the shearing action of a meshing block is reduced, and the problem of uncontrollable degradation of a degradable material in the machining process is solved; the toothed disk is arranged beside a vacuum opening, so that the material dispersing capacity of the screw is further improved. The screw can be used for reproducing and machining waste plastic; materials are forced by the stretching block to move backwards, so that local shear is reduced; disconnection of molecular chains in a secondary machining process of the waste plastic is reduced. The retention time of waste plastic melt in the screw is prolonged by virtue of the toothed wheel disk, so that the materials are repeatedly mixed in the screw.
