In, then the 2~3h that flows back at 80~85 DEG C, it is finally putting into 12h in 30 DEG C of thermostat water baths, the stannic oxide for obtaining Sb doped is molten
Glue；
4th step：The glass fibre of second step electroplate is immersed in the colloidal sol that third walks, then uniform and stable is hung down
Straight lifting comes out；
5th step：The 4th impregnated glass fibre of step is put into 30~60 min in 80~85 DEG C of drying box, is finally putting into
In Muffle furnace at a temperature of 450 DEG C 2h, obtain electroconductive glass fibre finished product.
