Can a single shear dispersion emulsifier handle materials of different viscosities, and what is its typical viscosity range?
Most standard shear dispersion emulsifiers can accommodate a wide viscosity range, from 100 mPa·s (low-viscosity serums and drinks) to 100,000 mPa·s (high-viscosity mascara, toothpaste, and ointments). This adaptability is enabled by two key design features:
Dual stirring configuration: For high-viscosity materials (60,000–100,000 mPa·s, such as night creams), the frame-type wall-scraping stirrer provides high torque to prevent material stagnation and ensure 360° mixing without dead zones. For low-viscosity materials (100–1,000 mPa·s, such as lotions), the high-speed dispersion disk accelerates phase fusion and particle dispersion to improve efficiency.
Variable frequency motor: The motor allows for stepless speed adjustment. For high-viscosity materials, it operates at low speeds (500–1,000 rpm) to avoid overloading the equipment, while for low-viscosity materials, it runs at high speeds (8,000–12,000 rpm) to maximize shearing intensity and particle refinement.
It should be noted that for ultra-high-viscosity materials (exceeding 100,000 mPa·s, such as solid adhesives), customized models with reinforced motors and heavy-duty stirring systems are required, as standard units lack sufficient torque for effective processing.
