What is a chemical emulsifier, and how does it work in chemical processes?

2026-01-16

What is a chemical emulsifier, and how does it work in chemical processes?

 
A chemical emulsifier is a specialized device that achieves phase fusion, particle refinement, and emulsion stabilization by generating intense shear, cavitation, and turbulent forces. Unlike emulsifiers for food or cosmetics, it is constructed to resist chemical corrosion, mechanical wear, and hazardous operating conditions.
 
Its core working mechanism adapts to the unique properties of chemical materials, involving three key stages:
 
  • Shearing: A high-speed rotating rotor (typically 3,000–20,000 rpm) draws materials into the narrow gap (0.1–0.5 mm) between the rotor and fixed stator. The significant velocity difference between the rotating rotor and stationary stator generates strong shear forces, breaking down large droplets, particles, or aggregates into micro-sized units (1–50 μm) to facilitate phase mixing.
  • Cavitation: Rapid pressure fluctuations in the shear gap create micro-bubbles in liquid materials. These bubbles implode instantly, releasing enormous localized energy to disrupt tight particle clusters and promote deep fusion between immiscible phases—critical for processing high-viscosity chemical mixtures like resins, greases, and adhesive formulations.
  • Dispersion: Turbulent flow generated by the shear head circulates materials continuously within the chamber, preventing re-agglomeration of dispersed particles and ensuring uniform distribution of phases. This stability is essential for maintaining consistent performance of chemical products (e.g., coating uniformity, adhesive bond strength, pesticide efficacy).
