The equipment has a high degree of automation. All switch components and all operating parameters of the equipment are stored in the PLC database in digital form, and communication interfaces can be reserved to facilitate customer connection.
The ultra-high temperature furnace body within 3000℃ can meet the carbonization and graphitization of graphene/polyimide composite films.
Using a digital display intelligent temperature control system, the temperature measurement and temperature control process is fully automatically completed with high precision. The system can heat up according to a given heating curve, and can store twenty different process heating curves with a total of 400 segments.
The interior of the furnace body and all pipes are all insulated and subjected to high-strength anti-corrosion treatment to adapt to the volatile deposition characteristics produced during thermal cracking during the carbonization and graphitization of the graphene/polyimide composite film.
Adopts internal circulation pure water cooling system; digital flow monitoring system; furnace conversion adopts high-performance medium frequency contactor; comprehensive PLC water, electricity and gas automatic control and protection system
The unique induction coil uses five times of insulation treatment to completely solve the problem of induction coils or applications that require high-temperature insulation. It ensures that the coil can still maintain good insulation performance even if the corundum ages and cracks, and can effectively prevent coil ignition, current leakage and other phenomena.
