1. the preparation method of a high-purity superfine active charcoal glue, it is characterized in that:

  • its step is as follows,(1) select battery lead plate;

    battery lead plate comprises anode electrode plate and cathode electrode plate, distance between anode electrode plate and the cathode electrode plate is 3-10mm, it is 50-80mm that anode electrode plate adopts thickness, length 300-700mm, the high purity graphite plate of width 300-700mm, the purity of high purity graphite plate 〉

    =99.99%, ash≤

    50ppm, volume density 〉

    =1.85g/cm 3, folding strength 〉

    =60Mpa, granularity<

    300 orders;

    It is 2-10mm that cathode electrode plate adopts thickness, length 300-700mm, the inert metal plate of width 300-700mm;

    (2) add electrolyte solution, electrolyte solution did not have battery lead plate, the specific conductivity of electrolyte solution≤

    3 μ

    s/cm, turbidity≤

    10 degree, total hardness≤

    20ppm, TDS≤

    100ppm;

    (3) plugged, begin preparation, a few days ago voltage control is between 36V-200V, and current control is at 0-3A, and initial voltage is 200V, prolongation along with the electrooxidation time, begin to occur the graphite carbon granules in the ionogen water, electroconductibility strengthens gradually, and electric current begins to rise, voltage progressively descends, and regulating voltage is not less than 36V;

    Since the 3rd day to end cycle, voltage control is between 3-36V, current control is between 3-30A, initial voltage is 36V, regulates electric current and is not less than 3A;

    Every 1-3h, open the processor for ultrasonic wave circular treatment once in preparation charcoal glue process, circular flow is 5-30L/min, single treatment time 10min-30min, odd-numbered day accumulation supersound process time 2-3h, hyperacoustic power is 1000-3000W, ultrasonic frequency is 10KHz-40KHz;

    When pH value 2.0-3.0, specific conductivity>

    1500 μ

    s/cm, the ORP of charcoal glue product are that 200-400mv, carbon content are 0.5-5%, charcoal glue particle diameter D50 stops preparation when 5-100nm, namely get desired product.
