PROCESS FOR WASHING POWDERY AND/OR GRANULAR RESINS AND A WASHING DEVICE THEREFOR

摘要

WASHING PROCESS FOR POWDERY AND/OR GRANULAR RESIN AND WASHING DEVICE FOR USE IN THE WASHING PROCESS A process for washing a powdery and/or granular resin involves bringing the powdery and/or granular resin into contact with a washing liquid in a counterflow fashion in a tubular body with a plurality of static mixing elements disposed continuously in series, thereby removing impurities adhering to the powdery and/or granular resin and producing the powdery and/or granular resin with a less content of impurities. A washing device for use with the washing process contains an tubular body in which the static mixing elements are disposed continuously in series, and this construction is simpler than conventional ones and does not require a stirring power and mechanism to remove the impurities from the powdery and/or granular resin.
