Parallel twin screw extruder utility rangeParallel twin-screw extruders are widely used in the filling, blending, modification, reinforcement, devolatilization of chlorinated polypropylene and super absorbent resin degradable master batch; polyamide polycondensation, extrusion by addition polymerization of polyurethane, granulation of carbon powder and magnetic powder, insulating and sheathing materials for cables, low smoke and low halogen flame retardant PVC cable materials and preparation of various Silane crosslinkers, etc. . Small models are mainly used for scientific research and teaching.
Parallel twin screw extruder characteristics:
Parallel twin screw extrusion system:
The screw and the cylinder adopt the structure of "Building Block" , which has good interchangeability and can be used in any combination according to the different material processing technology;
The cylinder body is made of nitrided steel and bimetallic material, which is wear-resistant, corrosion-resistant and can prolong its service life;
Nitrided steel and high-speed steel are used for screw thread elements, and the curve is made of computer-aided design steel, which ensures normal tooth surface clearance of screw thread working section and good self-cleaning The strength of the threaded element and the Mandrel is enhanced by the special designed connection and transmission,
The above measures realize the purposes of uniform material dispersion, good mixing and plasticizing effect, Short material retention time and high conveying efficiency.
Adopt special reduction box of plastic machinery, transmission parts adopt high-quality, super-high alloy carburizing steel, combined with carburizing, quenching, gear grinding process, key parts are made with surface strengthening treatment, tooth surface strength HRC54-62, core hardness HRC30-40, gear 6. The system has high speed, high torque, low noise advantages and so on.
Adopting twin screw with agitator quantitative feeding system, and the feeding process is uniform, accurate, without shelf phenomenon.
Electronic Control System:
IMPORTED ELECTRICAL COMPONENTS, control panel for man-machine interface, "module" type control for each part of the equipment can also be configured according to user requirements. Multi-functional module structure is clear, with safety interlock devices such as lubrication loss of pressure protection, head pressure protection, over-current protection, truly reflecting the equipment operation with provided accurate control, high sensitivity, easy operation.
Adopt cast aluminum, cast copper, ceramic resistance heating device, heating is uniform, fast and with high temperature control accuracy.
Temperature control system:
Double-channel temperature control speedometer realizs sensitive response, easy temperature setting, easy adjustment, high temperature control accuracy.
Adopting two methods from water cooling, fuel cooling or air cooling. And the cooling process is even, fast and efficient.
Built-in vacuum system, vacuum up to-0.09 MPA, which can ensure the full plasticization of materials and improve product quality.
According to the different process requirements of users, can choose cold pull bar pelleting, drag chain pelleting, air-cooled die surface hot, water ring hot, and other forms of pelleting.
