Graphitization Purification Furnace（Vgcf Purification）

Product Introduction：

Vertical structure, top-loading type, it is convenient for temperature measurement and aiming. Cylindrical furnace has higher heating efficiency. Carbon nanotubes grown by CVD with nano-catalyst particles need to remove the catalyst particles to obtain high-purity carbon nanotubes in practical applications. The high-temperature method is used to purify the growth, which can reduce the catalyst content in the carbon nanotubes to less than 5ppm. And obtain a higher degree of graphitization.

● Features：

● Continuously working temperature is 2850℃;

● Vertical Top Loading with single chamber or multi chambers design for high production capacity. The shell and door are water-cooled jacketed. Both outer and inner layer of the furnace shell and door is made of SUS304 stainless steel.

● The unique induction coil adopts 5 times of insulation treatment, which completely solves the application problem of induction coil or high-temperature insulation, and ensures that the coil can maintain good insulation performance under the conditions of corundum aging and cracking, which can effectively prevent the coil from ignition and current leakage. And other phenomena.

● High vacuum pneumatic valves equipped with position indicator in order to automatic control of the vacuum and gas supply system.

● Over-temperature, over-pressure, gas status, water lack and power failure alarms and automatic mechanical interlock for over-pressure protection.

● High precision smart temperature controller which can store 20 programs with total 400 segments.

● International famous brand high accuracy pyrometer with temperature measuring range of 1000~3200°C or 600~3100°C. The accuracy of temperature measurement is 0.2~0.75%.

● Fully automatic PLC monitoring system.

● Remote operation, failure diagnosis and software upgrading.

● High automatic equipment, all the on/off switch components and all the running parameters are stored with the digital format in the PLC date base, there have communication interface for the convenience of customer intervene.

Optional Features:

● High Vacuum System: Vacuum and high vacuum operation of these furnaces is only possible up to 2200°C.

● Gas Purification System

● Closed Loop Cooling Water System
