This equipment is a 1L polyester reactor experimental system, equipped with a jacketed polycondensation collection tank and a jacketed vacuum buffer tank. To enhance its applicability in other polyester research directions, it features an esterification pipeline system including an esterification fractionation column, condenser, and glass esterification collection tank. The reactor is designed with a working pressure of 1 MPa and a temperature rating of 310°C. It integrates multiple functions: pressure display, gas inlet/outlet ports, liquid/solid feeding ports, safety protection devices, temperature monitoring, and vacuum level display.
The system employs a high-torque magnetic coupling stirrer delivering 28 N·m torque output via a reducer and belt transmission. Oil bath heating ensures rapid temperature rise while maintaining uniform temperature distribution within the reactor. Equipped with a vacuum pump and vacuum gauge, it achieves precise vacuum control with an ultimate vacuum level of 3 Pa.
A 10.2-inch touchscreen interface with dedicated control software enables real-time monitoring and recording of reactor parameters (temperature, pressure, stirring status, vacuum level). Features include tiered pressure/temperature alarms, process data logging/transmission, historical trend statistics, and remote operation via PC or mobile app.
