Screw configuration in the melt-plasticizing section

PARALLEL TWIN-SCREW EXTRUDER


The optimum screw local configuration for melt plasticizing a given polymer depends on the material's specific heat, melting point, melt viscosity, and particle size of the polymer in the solid state. The goal of the local screw configuration design for melting and plasticizing is to melt the material uniformly and quickly at the set temperature without inputting too much energy to the material.



There are two heat sources to melt the material, one is the external heat provided by the barrel heater, the other is the shear heat introduced by the screw, the latter is the main one. In order to introduce shear heat, kneading blocks, reverse screw elements, and reverse internal mixer rotor non-standard screw elements should be set in the melting and plasticizing section, and these elements should be placed at the predetermined axial position of the screw and its upstream forward thread Components are effectively combined.



The standard for evaluating the quality of the local screw configuration used in the melting and plasticizing section should be that it can convert mechanical shear energy into heat energy, so that the material can be melted fastest and most thoroughly without increasing the temperature of the material, that is, Energy utilization is the most reasonable.
