Description

Technical Field

[0001] The utility model relates to the technical field of screw extruders, in particular to a barrel structure of a screw extruder. Background Art

[0002] The screw extruder is one of the most important equipment for the melt molding of polymer plastic materials. It uses external power transmission and heat transfer of external heating elements to carry out solid conveying, compaction, melting, shearing, mixing and extrusion molding of plastics. The extrusion process of traditional screw extruders is achieved by external heating of the barrel, friction between solid materials and the barrel, screw and shear force of the melt. "Friction coefficient" and "friction force", "viscosity" and "shear stress" are the main factors affecting the working performance of traditional screw extruders. Since the factors affecting "friction" and "viscosity" are very complex, the extrusion process of traditional screw extruders is an unstable state and difficult to control, which is particularly prominent for certain heat-sensitive plastics with poor thermal stability and high viscosity.
