Performance Analysis of Twin Screw Extrusion Pelletizer

It can be applied to the concentration, oxygen removal, dehydration, extrusion, drying, extraction of monomers and solvents of polymers such as plastics, rubber and synthetic fibers. The co-rotating parallel twin-screw extruder is also suitable for the processing of various resin powders, corner wastes, gate runner materials, old films and broken wires, and has good working performance.

The twin-screw extrusion granulator can be widely used in pre-plasticizing and compounding processes, such as mixing plasticizers, stabilizers, foaming agents, pigments and cross-linking agents well to provide raw materials for granulation and calendering processes. At the same time, glass fiber can be added to improve the strength and stiffness of plastics, calcium carbonate and talc can be added to increase the rigidity of the product, asbestos and mica can be added to improve heat resistance, carbon black can be added to improve the thermal conductivity of the product, aluminum hydroxide, Slag expansion and waste cotton yarn can improve plastic properties, save oil resources and eliminate hazards. If polypropylene and polyethylene are blended in the machine, a polymer material with good comprehensive properties can be obtained.

On the twin-screw extruder, it can not only complete the plasticization molding process, but also complete or partially complete the polymer polymerization reaction. For example, a two-stage zsK co-rotating twin-screw extruder can mix caprolactam with catalysts, accelerators, etc. for polymerization, and obtain polycaprolactam (nylon 6) with a molecular weight of 70,000 to 100,000 through the exhaust process. Material. Solvent plants have succeeded in preparing POM on a two-stage zSK twin-screw extruder.
