The application scope of parallel twin screw extruder
Parallel twin-screw extruder is widely used in rubber and engineering resin filling, blending, modification, enhancement and high absorbent resin, chlorinated polypropylene waved off; Biodegradable masterbatch, polycondensation of polyamide, polyurethane addition polymerization reaction extrusion; Carbon powder, magnetic powder granulation, cable insulation material, sheath material, low smoke low halogen flame retardant PVC cable and all kinds of silane crosslinking material preparation, etc. Small machine is mainly used in scientific research and teaching.
Product features
Direction parallel twin-screw extrusion system:
Screw, barrel structure of "building block", has a good interchangeability, according to the different of material processing technology, arbitrary combination; Shell USES steel nitride, double metal materials, wear resistance, corrosion resistance, prolong service life; Thread element selects nitride steel, high-speed steel, curve using computer aided design, with unique processing technology, thus ensuring the normal tooth surface of thread work clearance, and self-cleaning property; A specially designed connection mode, transmission enhances the thread element, core shaft strength, the above measures to realize the material dispersed evenly, mixing plasticizing effect is good, the material retention time is short, the purpose of high transmission efficiency.
Reduction system:
Plastic machinery dedicated reducer, transmission parts, respectively [1] is made of high quality, super alloy carburizing steel, carburizing, quenching, grinding process manufacturing, key-module increased the surface strengthening treatment, tooth surface strength HRC54-62, the core hardness HRC30-40, gear level 6, the system has characteristics such as high speed, high torque and low noise.
Feeding system:
Quantitative feeding system adopts double screw with stirrer, feeding uniform, accurate, do not produce material phenomena.
Electrical control system:
Imported electrical components, the control panel for the man-machine interface, equipment parts "module" type control (can also be configured according to user requirements), multi-function module structure is clear, with a safety interlock device (such as loss of pressure lubrication protection, head pressure protection, over-current protection, etc.), reflect the equipment running status, control accuracy, high sensitivity, easy to operate.
Heating system:
Using cast aluminum, cast copper, ceramic resistance heating device, uniform heating, heating up fast, temperature control precision is high.
Temperature control system:
Adopt dual channel temperature control table, responsive, temperature setting, convenient adjustment, high temperature control precision.
Cooling system:
Take the water cooling, oil cooling, wind cooling two forms, cooling rapidly, uniform, the effect is good.
The vacuum system:
Built-in vacuum system, vacuum degree can reach 0.09 Mpa), to ensure material plasticizing adequately, improve the quality of products.
Auxiliary machinery:
According to the different process requirements of users, can be equipped with cold brace dicing, drag chain traction dicing, air-cooled die eagerly, cut water ring eagerly wait for a variety of forms.
