Description

【発明の詳細な説明】 本発明は鉛蓄電池極板用ペースト練合法に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paste mixing method for lead-acid battery electrode plates.

鉛蓄電池極板に用いるペースト中に７乃至１０％程度の
四塩基性硫酸の鉛が混入されていると、匹塩基性硫酸塩
が混入されていない電池と比べ寿命が長くなる。If about 7 to 10% of lead in tetrabasic sulfate is mixed into the paste used for the electrode plates of lead-acid batteries, the battery life will be longer than that of a battery that does not contain an equivalent amount of basic sulfate.

四塩基性硫酸鉛の投入量でペースト中の四塩基性硫酸塩
量を簡単に制御できる特徴を有するものである。However, if there is an unnecessary amount of tetrabasic lead sulfate, the battery life will be shortened. The temperature of the paste during paste kneading is
During kneading, the temperature tends to rise to 70°C or higher, and at the end of kneading it reaches 70°C.
The temperature will be as low as below ℃. When the paste temperature rises to about 70° C., tetrabasic sulfate is generated, and if tetrabasic lead sulfate has already been mixed in, this becomes the problem and the formation of tetrabasic lead sulfate is intense. For these reasons, mixing tetrabasic lead sulfate during kneading results in an increase in tetrabasic lead sulfate. In view of the above points, the present invention prevents the increase and growth of tetrabasic lead sulfate by mixing an appropriate amount of tetrabasic lead sulfate at the final stage of mixing of the paste used for lead-acid battery electrode plates.
It has the feature that the amount of tetrabasic sulfate in the paste can be easily controlled by the amount of tetrabasic lead sulfate added.

本発明の一実施例を説明する。An embodiment of the present invention will be described.

ペーストの練合終了時期のペースト中に既に完全に四塩
基性硫酸鉛化しているペーストを氷に溶かして適量投入
し、短時間（１乃至２分）練合してペースト中に四塩基
性硫酸鉛化したペーストを７乃至１０％均一に分布させ
る。At the end of paste kneading, the paste, which has already been completely converted into lead tetrabasic sulfate, is dissolved in ice and added in an appropriate amount, and mixed for a short time (1 to 2 minutes) to form tetrabasic sulfuric acid into the paste. Evenly distribute the leaded paste by 7-10%.

蓄電池は２７５サイクルであつた。One method for producing a paste made of tetrabasic lead sulfate is to put the paste in sulfuric acid with a specific gravity of 1260 at about 70°C to 100°C and leave it for about 2 hours. N using the thus obtained paste
As a result of conducting JIS standard cycle tests on S40Z type vertical batteries, lead-acid batteries that do not contain tetrabasic lead sulfate have a rating of 350.
The lead-acid batteries mixed with tetrabasic lead sulfate 109b had 400 cycles, and the lead-acid batteries mixed with 37% tetrabasic lead sulfate had 275 cycles.
