[0002] Plastic modified particles are general-purpose resins produced in large quantities by petrochemical enterprises through physical, chemical and mechanical methods to improve or increase their functions, so that they can be used under special environmental conditions in terms of electricity, magnetism, light, heat, aging resistance, flame retardancy and mechanical properties. Modified plastic particles are a field of the plastics industry with a wide range of applications, high technological content and the ability to create huge economic benefits. They are widely used and the preparation process requires the use of mixing equipment to mix raw materials and additives.

[0003] The existing mixing equipment for preparing modified particles has the following disadvantages when in use: the existing stirring equipment for preparing modified particles generally adopts a traditional stirring blade structure.

For this reason, we propose a corrosion-resistant modified particle preparation mixing stirring paddle. Utility Model Content
