What key factors should be considered when selecting a solid-liquid emulsifier?
A: When selecting a solid-liquid emulsifier, the following key factors need to be considered to ensure matching with production needs: ① Solid particle characteristics: Initial particle size, hardness, agglomeration tendency, and solubility—these determine the required shear force and rotor/stator structure. ② Liquid medium properties: Viscosity, density, and compatibility with solids—high-viscosity liquids require more powerful motors to ensure sufficient turbulence. ③ Production requirements: Batch volume (laboratory-scale: 5-50L, industrial-scale: 100-5000L), required particle size after dispersion (e.g., 5 μm for cosmetics, 20 μm for food), and production efficiency. ④ Process requirements: Whether vacuum deaeration (to avoid air bubbles), temperature control (to protect heat-sensitive materials), or online cleaning (CIP) is needed. ⑤ Material compatibility: The contact parts of the equipment (tank body, rotor, stator) should be made of materials suitable for the industry, such as 316L stainless steel for food and pharmaceuticals, and wear-resistant alloys for chemical materials. ⑥ Operational stability: Equipment noise, vibration, and maintenance difficulty should be considered for long-term production.
