Rock characterization instrument polyester polymerization reactor
✓
Accurate temperature control, efficient aggregation, and assistance in the research and development of new materials
The rock instrument polyester polymerization reactor is an experimental device designed specifically for the research and development of polymer materials. It is suitable for key process stages such as esterification (ester exchange), condensation, and vacuum devolatilization, and is compatible with various polyester systems such as PET, PBT, PLA, LCP, etc. The device adopts a modular design and supports different volume configurations of 0.5L~50L, meeting the full process requirements from basic research to pilot scale. It is widely used in innovative research and development in the fields of biobased polyester, degradable materials, copolymerization modification, catalyst screening, etc.
1、 Core advantages
High precision temperature control system
Adopting external circulation oil bath heating (RT~300 ℃), dual PID control, main control material temperature, auxiliary control inlet and outlet oil temperature difference, with an accuracy of ± 0.5 ℃, to avoid local overheating.
• Program temperature control function, supports multiple temperature curve settings, adapts to complex reaction conditions.
Multi stage vacuum system
Equipped with low pumping speed and high pumping speed dual vacuum pumps, the initial slow pumping avoids boiling, and the later high vacuum can reach below 50Pa (with material), ensuring efficient polymerization reaction.
The vacuum degree can be adjusted and controlled to meet the needs of different polymerization stages.
High viscosity material mixing system
316L stainless steel material, high temperature resistance, corrosion resistance, suitable for strong acid, strong alkali and high viscosity systems.
Anchor/frame+screw belt combination mixing, paired with a high torque motor, ensures uniform mixing of high viscosity materials (such as PLA, LCP).
Intelligent Control and Security Protection
PLC+touch screen control, real-time display of temperature, pressure, speed, current and other parameters, supporting data curve export (Excel format).
Multiple safety interlocks: automatic cut-off of heating for overpressure/overtemperature, dual monitoring of mechanical pressure gauge and sensor, and pressure relief protection of safety valve.
• Support remote monitoring (MODBUS communication) for laboratory management and data traceability.
Modular and flexible configuration
An optional online feeding system (dual valve constant pressure feeding tank) can be used to achieve continuous feeding in positive/negative pressure environments, avoiding system disturbance.
The esterification system consists of a distillation column, condenser, and receiving tank, supporting positive/negative pressure esterification reactions.
The jacket type discharge valve ensures safe discharge and can clean the reaction kettle in a closed manner.
