The introduction of GEFC-GFE Graphite Felt Electrode



GEFC-GFE Graphite Felt Electrode 
CFF in vacuum or inert atmosphere after heat treatment above 2000 ℃, graphite felt, carbon compared with carbon fiber felt, more than 99%. The world in the late 1960s has been the supply of goods of the graphite felt. Graphite felt due to the selection of the original felt divided into PAN-based graphite felt and glue-based graphite felt two.
Process will be cut to the required size of PAN-based carbon fiber felt or viscose-based carbon fiber felt, roll into a tube-like into the container of graphite material, graphite container placed in the high-temperature furnace (high-temperature furnace for graphite tube furnace, IF protection, high-frequency induction furnace or other heating forms of high temperature furnace), vacuum or high purity inert gas, heated to 2200 ~ 2500 ℃ to 100 ~ 300 ° C / h heating rate, and then natural cooling to 100 ° C have .
PAN-based graphite felt Viscose-based graphite felt a strong big, strong antioxidant capacity, but poor flexibility, bulk density, good insulation properties. In addition to their high purity, with massive graphite and high temperature resistance, corrosion resistance, does not melt characteristics, as well as flexible, can be freely folded, cut and available graphite yarn stitching advantages. The main purpose of the graphite felt as a single crystal silicon smelting furnace insulation materials. High purity corrosive chemical reagents can be used as filter material in the chemical industry. Graphite felt in the non-oxidizing atmosphere under the conditions of temperature up to about 3000 ℃.
Brief Introduction: GEFC-GFE Graphite Felt Electrode is the top able circulation electrode able by graphitizing the specia PAN acquainted aloft 2500 ℃, and is about acclimated for vanadium redox array with GEFC-10N perfluorinated ion barter membrane.
