Problems solved by technology

[0002] At present, the traditional artificial graphite furan resin impregnation process in China is to use an impregnation kettle to soak the artificial graphite electrode in acid, vacuumize, impregnate, cool, and dry. The main disadvantage of the acid soaking step is that the graphite electrode is soaked in strong acid. The operation brought safety hazards, and caused the furan resin to be unusable after repeated soaking in acid, resulting in waste

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...

Abstract

The invention discloses a recyclable furan resin impregnation technology. The technology comprises dust removing and drying, vacuum pumping, impregnation, curing and cooling, vacuum pumping, impregnation, curing and cooling are performed repeatedly according to the technological steps, the vacuum pumping step refers to that a graphite electrode is subjected to vacuum pumping until the pressure is 0.08 Mpa and kept for 2 h, and during impregnation, the graphite electrode is subjected to vacuum pumping until the pressure is 0.6 Mpa and kept for 2 h; the curing step refers to that the graphite electrode is cured at the temperature of 160-180 DEG C for 1 h and then cooled to the normal temperature. According to the furan resin impregnation technology, an acid soaking technology is omitted, so that furan resin can be recycled, the production cost is reduced, and the enterprise benefit is increased.

Description

technical field [0001] The invention relates to the technical field of a graphite impregnation process, in particular to a recyclable furan resin impregnation process. Background technique [0002] At present, the traditional artificial graphite furan resin impregnation process in China is to use an impregnation kettle to soak the artificial graphite electrode in acid, vacuumize, impregnate, cool, and dry. The main disadvantage of the acid soaking step is that the graphite electrode is soaked in strong acid. The operation has brought potential safety hazards, and caused the furan resin to be unusable after repeated soaking in acid, thereby causing waste. Contents of the invention [0003] Purpose of the invention: The present invention aims at the deficiencies in the prior art and proposes a recyclable furan resin impregnation process. [0004] Technical solution: A recyclable furan resin impregnation process according to the present invention comprises the following step...
