With 1. carboxymethylcellulose sodium solution, 2. the ptfe emulsion of poly-vinyl alcohol solution and mole percent concentration 60% mixes to stir and promptly makes mixed liquor;
4. the weight ratio of dry powder preparation is ball-type nickel hydroxide (Ni (OH)
2): cobalt protoxide (CoO)=3-4: 0.15-0.25
With ball-type nickel hydroxide (Ni (OH)
2) take by weighing in proportion with cobalt protoxide (CoO) and to mix, in ball mill, fully mix;
5., step dry powder is 4. at the uniform velocity added in the step mixed solution 3. 3. slowly under the stirring condition in step, add dry powder after, stirred fast 1-2 hour, promptly make the positive plate slurry;
(3) the positive plate slurry is changed over to the hopper of tensile pulp machine;
(4) dressing section: the two-sided burr steel belt of nickel plating by putting belt wheel → hopper → mould for pulling paste → syllogic drying tunnel → precompressed twin rollers → take-up pulley → section; 1. the syllogic drying tunnel temperature is respectively 120-140 ℃, 110-130 ℃, 100-120 ℃; 2. slurry speed 150-180 rev/min;
(5) finished product: the spot welding positive plate lug of will cutting into slices, make the finished product positive plate.
The manufacture method of nickel-cadmium alkaline battery positive plate of the present invention adopt the two-sided burr steel belt of nickel plating to make substrate, but streamline production has improved production efficiency, has improved the utilance of nickel, has reduced cost, the production efficiency height, and technology is simple.
