Graphite Rigid Felt Insulation Cylinders

Semicorex graphite rigid felt insulation cylinders are manufactured via a series of processes that involve forming soft felt into the cylindrical preforms, impregnating and curing it with resin and other binders, followed by carbonization and graphitization. The special combination of resin and carbon fiber graphite felt achieves a synergistic performance effect, making graphite rigid felt insulation cylinders effectively optimize the temperature uniformity in the thermal field and significantly improve the overall thermal utilization efficiency of the furnace system.

The advantages of Semicorex graphite rigid felt insulation cylinders

1.Reliable high-temperature resistance

Semicorex graphite rigid felt insulation cylinders exhibit reliable high-temperature resistance, resulting in long-term stable operation at temperatures over 2000°C. Without softening, deformation, or volatile emissions, graphite rigid felt insulation cylinders are able to maintain excellent structural integrity and performance stability during high-temperature conditions.

2.Exceptional thermal insulation performance

Carbon fiber rigid felt materials feature low thermal conductivity, which can effectively reduce heat loss. There are numerous micro-pores and voids within the material structure forming uniform heat conduction paths, resulting in consistent temperature distribution. Leveraging these superior material properties, Semicorex graphite rigid felt insulation cylinders can stably maintain furnace temperature and lower energy consumption, while also optimizing thermal field uniformity and mitigating product yield decline caused by non-uniform temperature gradients.  

3.Superior cleanliness performance

Semicorex graphite rigid felt insulation cylinders have ultra-low impurity content and excellent corrosion resistance. They can minimize the contamination of the furnace cavity caused by the release of chemical reactants and high-temperature volatiles. This ensures minimal contamination during harsh operating conditions such as high temperatures, vacuums, or inert gas atmospheres, which is crucial for delicate procedures like crystal growth that have strict cleanliness standards.

4.Lightweight and rigid structure

Featuring excellent mechanical strength, Semicorex graphite rigid felt insulation cylinders can withstand certain loads and serve directly in the insulation parts of equipment. Different from the conventional dense refractory materials, they feature low density and light weight. Their lightweight structure minimizes the overall load on the furnace support system, facilitates easy installation and disassembly, and greatly reduces maintenance and replacement costs.
