What are the critical rules to pay attention during manufacturing masterbatch especially when working with inorganic nanoparticles? What should be considered in order to achieve the homogenously dispersion in the polymer matrix without destroying the screw and the polymer?
1. Use a high-shear mixing element in the extruder to ensure that the particles are evenly dispersed.
2. Use a low screw speed to reduce the risk of particle breakage.
3. Use a low temperature setting to prevent thermal degradation of the particles.
4. Use a low back pressure setting to reduce the risk of particle agglomeration.
5. Use a vacuum system to remove air from the extruder barrel and reduce the risk of particle oxidation.
6. Use a cooling system to reduce the risk of thermal degradation of the particles.
7. Use a filter system to remove any particles that may have been damaged during the extrusion process.
8. Use a pelletizing system to ensure that the particles are evenly distributed in the masterbatch.
