Overview
Roland Graphite E+20 Composite Hard Felt Graphite Ark is made of high-quality PAN based graphite felt selected by Hongnaide. It is bonded, cured, formed, and high-temperature graphitized through special processes. Carbon cloth can be attached to the surface according to customer requirements Charcoal paper or a combination of both can prevent fuzzing, resist airflow erosion, and increase strength.
Product Details
Roland Graphite E+20 Composite Hard Felt Graphite Ark
1. Graphite heater: As one of the core components of a vacuum furnace, the graphite heater utilizes the principle of graphite resistance heating to convert electrical energy into thermal energy, which is used to heat the materials inside the furnace. It has the advantages of fast heating speed, uniform temperature, energy saving and environmental protection.
2. Ink boat: a component used to carry materials, shaped like a ship, hence called a boat. The graphite boat has the characteristics of high temperature resistance, corrosion resistance, and high strength, and can withstand high temperatures and high pressure.
3. Other graphite accessories: In addition to the two main accessories mentioned above, vacuum furnaces also commonly use graphite insulated carbon felt, graphite heating rods, graphite furnace guide rails, graphite nozzles, graphite conductive rods, graphite connectors, graphite columns, graphite furnace seats, graphite screws, graphite nuts, graphite beams and other graphite products. These accessories play different roles in vacuum furnaces, such as insulation, conductivity, connection, etc.
1. Heating element: Graphite heating elements in vacuum furnaces are widely used in high-temperature processing and heat treatment processes. They can withstand high temperature environments and quickly and uniformly conduct heat to bring the sample to the desired temperature.
2. Thermal insulation cover: Graphite thermal insulation cover is used for thermal insulation in vacuum furnaces, which can effectively reduce heat loss, maintain stable furnace temperature, improve furnace energy efficiency, and reduce energy consumption. Hongnaide Carbon
3. Carrying and handling samples: Graphite boats and other accessories are used as containers for carrying and handling samples in vacuum furnaces. They have excellent high temperature resistance and chemical stability, and can withstand heat treatment conditions.
1. Chemical stability and corrosion resistance: Vacuum furnace graphite parts have good chemical stability at room temperature and are not corroded by any strong acids, alkalis, or organic solvents. This makes graphite components have a long lifespan and low wear and tear during use.
2. Antioxidant and reducing effects: When graphite parts are heated, negative oxygen ions are generated, which activate surrounding objects, maintain human health, effectively prevent aging, and make the skin shiny and elastic. At the same time, this characteristic also helps to protect the performance of graphite parts at high temperatures. Hongnide graphite
3. Energy saving, hygienic, non radioactive, high temperature resistant: Graphite is stable at high temperatures, non-toxic and harmless, so it is widely used in high-temperature equipment such as vacuum furnaces. Its high temperature resistance enables graphite fittings to maintain stable performance in the working environment.
In summary, graphite accessories for vacuum furnaces play a crucial role in their operation. They not only have multiple types and functions, but also excellent performance and characteristics, which can meet the working requirements of vacuum furnaces in high temperature and high pressure environments.
