ミクロン以下の微細を粒子径のものは殆んど得られず。The conventional paste manufacturing method for the cathode of lead-acid batteries uses commercially available powder for barium sulfate, or causes secondary aggregation of fine powder particles, resulting in particles ranging from several microns to single large particles. 1, which forms a mass and is effective as a crystal nucleus.
It is almost impossible to obtain particles with a fine particle size of less than a micron.

る。In order to achieve the above object, the present invention introduces a barium hydroxide solution during water kneading during kneading to uniformly disperse barium ions on the surface, inside, and surrounding water of lead oxide particles. After kneading with water, add diluted sulfuric acid and homogenize fine barium sulfate into the paste through a chemical reaction to obtain barium sulfate, which is optimal as a crystal nucleus for lead sulfate, and use it as a cathode plate for lead-acid batteries. It is possible to improve the lifespan of.

く問題ないこと化ある。The features of the present invention are that there is no need to install a special powder machine to make barium sulfate fine, and there is no secondary coagulation of particles among each other, and the process can be carried out using 311 manufacturing equipment. There is no need to change anything (depending on achieving the purpose, control the temperature and dilute sulfuric acid concentration).The optimum particulate barium sulfate can be easily obtained and there is no problem at all since the reaction by-product is water. There is something special.

When the paste becomes soft, add 1091 barium hydroxide aqueous solution until the amount of barium becomes 19 g based on the weight of lead oxide and mix thoroughly. After that, approximately 6 times equivalent amount of constant III sulfuric acid was added to the amount of barium to generate fine crystals of barium sulfate, and then dilute sulfuric acid of 10 μm was gradually added for 10 minutes to achieve the desired paste density. ,
Finally, mix for 10 minutes.
