Embodiment 1
[0031] An embodiment of the present invention provides a method for cleaning finished copper wire after oxidation, comprising the following steps:
[0032] (1) Wind the oxidized copper wire to be treated on the iron pan and put it in the furnace gall of the annealing furnace;
[0033] (2) Put industrial alcohol with a purity of 95% in a glass bottle with a capacity of 500ml, then place it in an annealing furnace, and vacuumize the furnace to minus 0.1MPa;
[0034] (3) Pass carbon dioxide into the furnace until the pressure in the furnace is 0.25MPa, and then heat it up,
[0035] Specifically, three heating points, upper, middle, and lower, are set in the annealing furnace to uniformly heat the furnace. Among them, the heating temperature of the upper phase is 420°C, the heating time is 80 minutes, and the holding time is 40 minutes; the heating temperature of the middle phase is 420°C, the heating time is 60min, and the holding time is 40min; the heating temperature of the lo...
Embodiment 2
[0039] An embodiment of the present invention provides a method for cleaning finished copper wire after oxidation, comprising the following steps:
[0040] (1) Wind the oxidized copper wire to be treated on the iron pan and put it in the furnace gall of the annealing furnace;
[0041] (2) Put industrial alcohol with a purity of 99% in a glass bottle with a capacity of 500ml, then place it in an annealing furnace, and vacuumize the furnace to minus 0.1MPa;
[0042] (3) Pass carbon dioxide into the furnace until the pressure in the furnace is 0.35MPa, then heat,
[0043] Specifically, three heating points, upper, middle and lower, are set in the annealing furnace to uniformly heat the furnace. Among them, the heating temperature of the upper phase is 590 ° C, the heating time is 80 min, and the holding time is 40 min; the heating temperature of the middle phase is 590°C, the heating time is 60min, and the holding time is 40min; the heating temperature of the lower phase is 590°...
