The main purpose of the lab twin screw extruder.
1. By blending plastics of different varieties and brands into homogeneous plastics alloys or blends, the polymer materials with new comprehensive properties are obtained.
2. Adding various inorganic fillers into plastics, such as calcium carbonate and talc powder, can greatly reduce the cost of raw materials and improve their physical and mechanical properties.
3. Mixing plastics with various additives, such as stabilizers, flame retardants, colorants and high concentration masterbatches, can obtain highly dispersed mixing effect.
4. Reinforcing materials such as glass fiber and carbon fiber are added to plastics to improve the physical and mechanical properties of plastics.
5. polymer homogeneous granulation, such as eliminating fish eyes and improving transparency.
6. Exhaust gas, devolatilization, that is, removing the residual monomer, solvent, water, oligomer and other volatile components in the polymer while plasticizing and mixing.
7. By optimizing the screw assembly, the machine can also be used in the mixing and granulating of various powder materials and thermosetting plastics, as well as the reactive extrusion of polymers and other special fields.
