AI Technical Summary
Existing premixing devices for modified plastic raw materials have low mixing efficiency and are difficult to achieve uniform mixing. High-viscosity raw materials tend to adhere to the inner wall, resulting in uneven mixing and affecting the quality of modified plastics.
The design combines a hybrid structure and a dispersion structure. The hybrid structure uses multi-layer dynamic mixing and low-speed premixing, while the dispersion structure uses ultrasonic high-frequency vibration to disperse the material. Combined with an anti-stick coating, it peels off adhering raw materials, breaks up agglomerates, and reduces interfacial resistance.
It improves mixing efficiency, achieves uniform distribution of components with different densities, reduces wall adhesion, and enhances the quality stability of modified plastics.
