A microreactor is a laboratory research equipment mainly used for microchemical reactions, material preparation, and catalyst screening. It achieves effective synthesis and testing by accurately controlling reaction conditions.
The microreactor achieves effective reaction control through microfluidic technology and static sealing design, and its core principles include three aspects:
Mass and heat transfer optimization: Adopting microchannel design to increase the contact area of reactants, coupled with embedded heating modules (such as ceramic heating plates) to achieve second level temperature rise and avoid local overheating.
Static sealing magnetic drive: The internal and external magnetic rings are coupled to drive the agitator to rotate, without the need for mechanical shaft seals, solving the leakage problem in high-pressure reactions, and supporting stepless speed regulation from 0-1200r/min.
core functionality
Chemical reaction control: supports chemical processes such as catalytic hydrogenation and polymerization, with adjustable temperature (± 0.5 ℃ accuracy), pressure (0-20MPa), and stirring speed (0-1200r/min) to ensure accurate reaction conditions.
Material preparation: Used for the synthesis of nanomaterials, polymer materials, and photocatalytic materials, obtaining materials with specific properties by adjusting reaction parameters such as temperature and time.
Catalyst evaluation: Testing catalyst activity and selectivity, screening high-performance catalysts to optimize reaction efficiency.
The maintenance of microreactors should focus on the transmission system, sealing devices, safety devices, and daily cleaning and maintenance. The specific points are as follows:
Transmission system maintenance
Regularly check the oil level and quality of the gearbox to ensure that the oil level is normal and there are no leaks. Listen to the sound of the reducer, motor and other components running normally, and the temperature should be controlled within the range of 40-60 ℃. If abnormal noise or high temperature is found, timely maintenance is required.
Sealing device inspection
Focus on checking whether the connection between the mixing shaft and the round nut is loose, ensuring good sealing and no leakage. Regularly lubricate the packing box and mechanical seal components to prevent wear caused by dry abrasion.
Safety device verification
Verify the accuracy of safety devices such as safety valves and pressure gauges every month to ensure the correct installation of explosion-proof membranes and pressure gauge pipelines. After each use, it is necessary to check whether the kettle body is deformed or cracked, and whether the insulation layer has fallen off.
