Below in conjunction with the embodiment of the present invention, the present invention is explained and illustrated, but following embodiment is only the preferred embodiments of the present invention, not all.Based on the embodiment in execution mode, those skilled in the art are other embodiment that obtains under the prerequisite of not making creative work, all belong to protection scope of the present invention.
Embodiment mono-:
Pole plate, before entering curing room, requires to solidify flooring and uses watering moistening.To solidify indoor temperature and control 45 ℃, relative humidity is controlled at >=and 95%, pole plate, after coated plate, before entering curing room, rests on outdoor time≤15min.Positive lead plaster moisture control is at >=100g/kg lead plaster, and negative lead plaster moisture control is at >=90g/kg lead plaster.The anode diachylon apparent density is controlled at 4.40-4.45g/ml, and the cathode lead plaster apparent density is controlled at 4.45-4.50g/ml.
Pole plate is put into to curing room and be cured, this curing process is divided into three phases, moisturizing cure stage, heat preservation solidification stage and dry solidification stage,
