For the special application field of twin-screw extruder, the Key Laboratory of China domestic university ordered a set of two-stage high-torque twin-screw extruders from us. It is used for the reaction extrusion and devolatilization of high-temperature nylon materials, and at the same time has the process of blending high-temperature nylon + glass fiber/carbon fiber (GF/CF). Recently, the machine started successfully one-time in the laboratory, and passed the acceptance of the expert group.
The system is composed of 2 sets of CHT35D high-torque lab twin-screw extruders, with a torque class of 15.
The first-stage L/D is 88:1, max screw speed is 150 rpm, used for reaction and devolatilization, and is equipped with 2 sets of dynamic side exhaust devices.
The second-stage L/D is 48:1, max screw speed is 900rpm, used for revolatilization exhaust. At the same time, it is equipped with a high-speed side feeder, used for adding GF/CF according to the process needs.
The whole unit is controlled by Siemens PLC+Siemens touch screen, and is equipped with an industrial computer to achieve remote control in real time– remote monitoring, information storage and remote operation.
