Embodiment 1
[0020] A method for manufacturing a low-voltage high-energy zinc oxide resistance sheet, comprising the following process steps:
[0021] (1) Ratio of additives: In terms of molar percentage, in addition to the main material zinc oxide, additives include: 0.2% antimony trioxide, 0.8% titanium dioxide, 0.5% bismuth trioxide, 0.8% cobalt trioxide, carbonic acid Manganese 0.6%, silver nitrate 0.001%, tin dioxide 0.3%, boric acid 0.001%;
[0022] (2) Stirring and grinding of additives: add the additives with a good ratio and water equal to the weight of the additives into the ball mill for stirring and grinding, and the mixing and ball milling time is 3 hours;
[0023] (3) Mixing, dispersing, grinding and spray granulation of additives and main ingredients: Add zinc oxide, aluminum nitrate and binder PVA-1799 into the ball mill, disperse and grind for 120 minutes, and the weight ratio of aluminum nitrate to additives is 1: 300, the weight ratio of binder to zinc oxide is 1:100; t...
