What Is The Main Function Of Twin-screw Extruder?

The parallel twin-screw extruder is used for filling, blending, modifying, strengthening of rubber, plastic and engineering resin, deoscillating of chlorinated polypropylene and absorbent resin. Extrusion of degradable masterbatch, polyamide polycondensation and polyurethane polycondensation reaction; Carbon powder, magnetic powder granulation, cable insulation material, sheath material, low smoke and low halogen flame retardant PVC cable material and various silane crosslinking materials preparation.

The conical twin-screw extruder has the characteristics of uniform plasticizing mixing, high yield, stable quality, wide range of adaptation, long service life and direct molding of PVC powder. With the corresponding molding head mold and auxiliary machine, all kinds of thermoplastics, especially hard polyoxyethylene powder, can be directly extruded into plastic products such as tubes, plates, sheets, rods, films and profiles, and can also complete the modification of various plastics and powder granulation process. ZHJX series conical twin-screw extruder has stable performance, which can make melt plasticize well at low temperature. The extruder is simply equipped with cast aluminum heater, which has high thermal efficiency, fast and uniform heating, and is equipped with cooling fan. Specially designed transmission part, driven by a new type of inverter motor or DC motor, smooth operation, large transmission torque, high efficiency. Through the imported inverter or DC governor can achieve stepless smooth speed regulation, high precision, energy saving. Intelligent double display digital temperature controller, high control accuracy, small temperature fluctuation, overload protection and fault alarm, screw core oil circulation constant temperature, simple oil cooling and other functions, and equipped with vacuum exhaust pipe device and quantitative feeding device.

Its main functions include:

1. Filling and blending: It can effectively mix the filler and other components evenly into the base material.

2. Modification: Through the heating and shearing of the material, change the physical and chemical properties of the material, such as improving the melt strength and fluidity of the material.

3. Reinforcement: Add reinforcement materials (such as glass fiber) to the plastic to improve its mechanical properties.

4. Molding and mixing: Through the extrusion molding process, the material is processed into various shapes and sizes, while mixing to ensure material uniformity.

5. Devolatilization and exhaust: can remove volatile components and gases in the material, improve the purity of the material.

6. Reactive extrusion: In some cases, twin-screw extruders can also be used as reactors for polymerization or other chemical reactions.

These functions make twin-screw extruders widely used in plastics, rubber process plastics, composite materials and other fields.
