1、 Preparation before operation

1. Equipment inspection
   • Check whether all components of the homogenizer (such as homogenizer head, sealing ring, pipeline) are intact, without wear or cracks.
   • Confirm that the power and grounding wires are connected correctly to avoid the risk of electrical leakage.
   • Check if the cooling system (if necessary) is working properly to prevent equipment overheating.
2. Material adaptability
   • Select the appropriate homogenizer head and material (such as stainless steel, ceramic) based on the properties of the material (such as viscosity, temperature, corrosiveness).
   • Avoid handling materials containing large particles or hard impurities to prevent clogging or damage to the homogenization head.
3. Environmental Requirements
   • Ensure good ventilation in the laboratory to avoid the accumulation of flammable and explosive gases or dust.
   • The operating table should be stable and kept away from vibration sources to prevent equipment from tipping over.

2、 Precautions during operation

1. Parameter Settings
   • speed controlAdjust the speed according to the characteristics of the material to avoid overheating or material splashing caused by excessive speed.
   • stress regulationGradually increase the pressure to avoid damage to seals or homogenization heads caused by sudden high-pressure impact.
   • Temperature managementFor thermosensitive materials, it is necessary to control the homogenization temperature (such as through cooling jackets or ice baths).
2. Uniform feeding
   • Slowly add the material to avoid blockage or uneven homogenization caused by excessive one-time use.
   • For high viscosity materials, they can be preheated or diluted to reduce processing difficulty.
3. real-time monitoring
   • Observe the operating status of the equipment (such as noise, vibration, temperature), and immediately shut down for inspection in case of abnormalities.
   • Avoid prolonged continuous operation and regularly shut down for cooling (especially when dealing with high viscosity or hard materials).

3、 Security protection

1. personal protection
   • Wear protective goggles, gloves, and lab coats to prevent materials from splashing or coming into contact with the skin.
   • Avoid touching rotating parts (such as homogenizer heads and drive shafts) directly with your hands.
2. Emergency handling
   • Familiarize yourself with the location of the emergency stop button and immediately turn off the power in case of abnormal noise or leakage.
   • When the homogenizer head is stuck, do not forcefully start it. It needs to be disassembled and cleaned before use.
3. Fire and explosion prevention
   • When handling flammable materials, ensure that the equipment is well grounded and kept away from sources of fire.
   • Use an explosion-proof homogenizer (if dealing with volatile organic solvents).

4、 Cleaning and maintenance

1. Timely cleaning
   • Immediately disassemble the homogenization head, pipes, and other components after each use, and rinse them clean with clean water or appropriate solvents.
   • Prevent residual materials from drying and solidifying, which may cause difficulties or cross contamination in the next use.
2. regular maintenance
   • Check vulnerable parts such as sealing rings and bearings, and replace worn parts in a timely manner.
   • Lubricate transmission components (such as gearboxes) to ensure smooth operation.
3. Storage requirements
   • Clean and store in a dry environment to avoid rusting or corrosion caused by damp conditions.
   • When not in use for a long time, power on regularly to prevent components from getting stuck.

5、 Special scenario precautions

1. High-pressure homogenizer
   • Confirm the accuracy of the pressure gauge calibration before operation to avoid overpressure operation.
   • When releasing pressure, slowly open the valve to prevent material splashing.
2. ultrasonic homogenizer
   • Control the ultrasound power and time to avoid material denaturation caused by excessive processing.
   • Ensure that the probe is immersed in the material to prevent cavitation effects from damaging the probe.
3. Low temperature homogenization
   • When using low-temperature coolant, avoid direct contact with the skin to prevent frostbite.
   • Regularly check the sealing of the cooling system to prevent leaks.
