IMPELLER FOR STIRRING WITH IMPROVED MIXING EFFICIENCY AND DISPERSIBILITY

摘要

PURPOSE: A stirring impeller improving mixing efficiency and dispersibility is provided to prevent gelation corresponding to wide range mixing condition, thereby improving physical properties like a mixing property, etc and being effective for equalizing the molecule size of compound materials. CONSTITUTION: A stirring impeller comprises: a central axis (30) which is a center of rotation during stirring; and multiple first blades (10) which are adhered to the exterior of the central axis and protruded to a radius direction outer side. The multiple first blades comprise one or more end grooves which are formed in a radius direction outer side end and one or more first body grooves (12) which are separated from the groove. Each first blade is folded toward a plumb upper direction about a virtual slash (L) which is extended to a direction which is estranged from the central axis.
