Parallel twin-screw extruders are widely used in the filling, blending, modification, reinforcement of rubber and plastic and engineering resins, and the devolatilization of chlorinated polypropylene and superabsorbent resins; Extrusion of degradable masterbatch, polyamide polycondensation and polyurethane addition reaction; Granulation of carbon powder and magnetic powder, preparation of insulating materials, sheathing materials for cables, low smoke and low halogen flame retardant PVC cable materials and various silane crosslinkers, etc. Small models are mainly used for scientific research and teaching.
Application scope of parallel twin-screw extruder:
Parallel twin-screw extruders are widely used in the filling, blending, modification, reinforcement of rubber and plastic and engineering resins, and the devolatilization of chlorinated polypropylene and superabsorbent resins; Extrusion of degradable masterbatch, polyamide polycondensation and polyurethane addition reaction; Granulation of carbon powder and magnetic powder, preparation of insulating materials, sheathing materials for cables, low smoke and low halogen flame retardant PVC cable materials and various silane crosslinkers, etc. Small models are mainly used for scientific research and teaching.
Product features:
Parallel co-rotating twin screw extrusion system:
The screw and barrel adopt the "building block" structure, which has good interchangeability and can be used in any combination according to the different material processing technology; The cylinder is made of nitrided steel and bimetallic material, which is wear-resistant, corrosion-resistant and extends its service life; The thread element is made of nitrided steel and high-speed tool steel. The curve is designed with computer aided design and unique processing technology, thus ensuring the normal tooth surface clearance of the thread working section and good self-cleaning; The specially designed connection mode and transmission device enhance the strength of threaded elements and mandrels. The above measures achieve the objectives of uniform material dispersion, good mixing and plasticizing effect, short material retention time and high conveying efficiency.
Deceleration system:
The special reduction gearbox for plastic machinery is adopted. [1] The transmission parts are made of high quality and ultra-high alloy carburized carbon steel, combined with carburizing, quenching and gear grinding processes. The key parts are added with surface strengthening treatment. The tooth surface strength is HRC54-62, the core hardness is HRC30-40, and the gear is grade 6. The system has the characteristics of high speed, high torque, low noise, etc.
Feeding system: the quantitative feeding system with twin-screw and agitator is adopted, and the feeding is uniform and accurate, and there is no rack phenomenon.
Electric control system: imported electrical components are used, the control panel is human-machine interface, and all parts of the equipment are controlled by "module" type (which can also be configured according to user requirements). The multi-function module has a clear structure, and has a safety interlock device (such as lubrication pressure loss protection, head pressure protection, overcurrent protection, etc.), which truly reflects the operation status of the equipment, with accurate control, high sensitivity, and easy operation.
Heating system: cast aluminum, cast copper, ceramic resistance heating device is adopted, which is uniform in heating, fast in temperature rise and high in temperature control accuracy.
