CONTINUOUS COALESCENCE PROCESSES

摘要

PROBLEM TO BE SOLVED: To provide processes for continuously coalescing particles from an aggregated particle slurry.SOLUTION: The aggregated particle slurry is heated, and then coalesced by raising the pH. The coalesced particles are homogenized and exit as a coalesced particle slurry. A multi-screw extruder is used for the coalescing. These processes are useful for providing coalesced particles such as toner compositions.
