What are the operational precautions for chemical emulsifiers?

What are the operational precautions for chemical emulsifiers?

 
Safe operation is critical for handling hazardous chemicals, preventing equipment failure, and ensuring product consistency. Key precautions include:
 
  • Pre-Operation Checks: Inspect contact parts for corrosion, wear, or deformation; confirm explosion-proof components (motors, switches, wiring) are intact and functional; check ventilation systems for flammable or toxic fume removal; verify seals and gaskets for leaks.
  • Material Feeding: Avoid dry running—always add liquid materials to the chamber before starting the shear head. For solid-liquid mixing, add liquids first, then gradually add solids to prevent particle agglomeration and shear head blockage. For reactive chemicals, control feeding rate to avoid exothermic runaways or pressure spikes.
  • Process Monitoring: Continuously monitor temperature, pressure, and shear speed—high-speed shear generates frictional heat, which may trigger decomposition of heat-sensitive chemicals (e.g., peroxides, unstable intermediates). Use jacketed chambers for temperature control (cooling or heating) as needed.
  • Personal Protection: Operators must wear chemical-resistant PPE (gloves, goggles, face shields, protective clothing) to avoid exposure to corrosive, toxic, or irritating materials. For flammable materials, ensure the workspace is well-ventilated and equipped with gas detection systems.
  • Post-Operation Cleaning: Clean the equipment immediately after use with compatible solvents (avoid chemical reactions with residual materials). For corrosive residues, neutralize before cleaning. Ensure thorough drying to prevent internal corrosion or biofilm formation (for water-soluble materials).
