Embodiment 1~8
[0041] The preparation method of embodiment 1~8 is identical, and the difference of activator used, consumption ratio see table 1 for details;
[0042] The activation method of the manganese dioxide solid slag of embodiment 1~8, comprises the steps:
[0043] Filter out the manganese dioxide solid residue and wash it to obtain manganese dioxide coarse material; add component A of the activator to the manganese dioxide coarse material in parts by weight, mix well, activate the temperature at 60°C, and activate the time for 60 minutes; then press Add component B of the activator in parts by weight, mix evenly, activate at 60°C, and activate for 60 minutes; after activation, filter and dry to obtain active manganese dioxide.
Embodiment 9~11
[0045] The proportion by weight of A and B components is the same as that of Example 6 in Examples 9-11. The difference is that the activator of Examples 9-11 also contains a dispersant, and the dispersant and component B are mixed at room temperature; see Table 1 for the dosage ratio;
[0046] The activation method of the manganese dioxide solid slag of embodiment 9~11, comprises the steps:
[0047] Filter out the manganese dioxide solid residue and wash it to obtain manganese dioxide coarse material; add component A of the activator to the manganese dioxide coarse material in parts by weight, mix well, activate the temperature at 60°C, and activate the time for 60 minutes; then press Add component B of the activator and dispersant in parts by weight, mix evenly, activate at 60°C, and activate for 50 minutes; after activation, filter and dry to obtain active manganese dioxide.
