Effect of different dispersion blade designs on processing parameters and properties of solvent borne coating

SHERAZ AHMED QURESHI

Abstract


The effect of different dispersion blade designs on processing parameters and different properties of solvent borne white paint was observed. Alkyd based solvent borne white paint sample was processed as a reference coating. Three paint samples were produced having same formulation by replacing different agitator dispersion blades with same diameters. It was found that dispersion blade designs affect loading time, dispersion time and total processing time. Different blades also have an impact on power consumption and processing temperature. Solvent borne paint whiteness and opacity is also affected by blade design. Effect on vortex formation and temperature during dispersion is also evident.
