Embodiment 1
[0025] A kind of recyclable furan resin impregnation process of the present invention comprises the following steps:
[0026] (1) Dust removal and drying: the graphite electrode is subjected to dust removal treatment to remove impurities and dust, and dried to an anhydrous state;
[0027] (2) Vacuuming: Put the dedusted and dried graphite electrode into the impregnation container to vacuumize to 0.08Mpa and keep it for 2 hours;
[0028] (3) First impregnation: Add furan resin into the impregnation container, vacuumize to 0.6Mpa, and keep it for 2 hours;
[0029] (4) Drain: Drain the resin attached to the graphite electrode to remove the resin tumor on the electrode surface;
[0030] (5) Solidification and cooling: solidify the graphite electrode at 160°C for 1 hour, and cool to room temperature;
[0031] (6) Vacuuming: Put the graphite electrode into the impregnation container again to vacuumize to 0.08Mpa and keep it for 2 hours;
[0032] (7) The second impregnation: ad...
