Rayon Graphite Felt

Rayon graphite felt material is a fibrous carbon of high carbon content. It retains its integrity at 3000°C heat treatment. It has low density, low thermal mass, fast heat dissipation, and high heat resistance. The material also contains minimum ash and sulfur impurities. It reduces gassing and shows excellent oxidation resistance.

 Rayon graphite felt advantages

The properties of rayon graphite felt are excellent: it is electrically conductive, thermally stable, and chemically stable. It is especially conductive electrically, which can be applied in electronics and communications. The material is resistant to extreme conditions like high temperatures and strong acids or alkalis.

Aplicación

Rayon graphite felt can be applied in many areas because of its properties. It is used as a high-temperature insulator in vacuum and inert gas furnaces. It also finds application in furnace insulation and parts. The graphite felt has many applications in the energy industries where it serves as a cathode for flow batteries and as reaction surfaces in electrochemical processes. For manufacturing applications, it serves as heat shields, sinks, and as thermal insulation from welds and solder spots. Also, it finds applications in glass blowing, ultra-light furnace wicks, car exhaust pipe liners,. Its versatility extends to battery technologies, pilas de combustible, and space for precise insulation and thermal management.

How to make rayon graphite felt?

The major steps involved in the preparation of rayon graphite felt include raw material selection, mixing, molding, heat treatment, and surface treatment. Artificial graphite is generally used as the raw material. Grafito particles of suitable sizes are obtained by crushing and screening. The particles are mixed together with additives like binders and plasticizers to give a uniform consistency. These mixtures are shaped, either by molding or extrusion. Heat treatment strengthens the bonding through sintering at high temperature, producing mechanically resistant graphite felt. Surface treatments enhance wettability and corrosion resistance by improving performance.

Carbon Felt VS Graphite Felt

They also differ in composition, properties, and uses. Carbon felt is made through the process of carbonization of fibers. Graphite felt undergoes graphitization, a process that raises its thermal and electrical conductivities. Carbon felt, however, is good to go-for medium temperatures, while graphite felt works amazingly at ultra-high temperatures. Graphite felt is costlier, with higher durability and efficiency in harsh environments.
