Summary of the invention
Technical problem to be solved by this invention is to overcome the defective of above-mentioned prior art and provide a kind of and can reduce the tap water consumption significantly, and can improve the method for cleaning positive plate after formation of lead-acid battery plates of positive plate storge quality.
The alleged problem of the present invention is solved by following technical scheme:
A kind of method for cleaning positive plate after formation of lead-acid battery plates, it is undertaken by following step:
A. dispose soaking solution:, stir according to mass concentration 1～2% configuration soaking with sodium hydroxide liquid;
B. soak: the positive plate after will changing into is immersed in the above-mentioned soaking with sodium hydroxide liquid, soak time 2～6 minutes;
C. dry: the positive plate after will soaking takes out, and send drying machine to carry out drying.
Above-mentioned method for cleaning positive plate after formation of lead-acid battery plates, the positive plate assay plate face pH value after the immersion is 4～6.
Above-mentioned method for cleaning positive plate after formation of lead-acid battery plates after every batch of positive plate through soaking takes out, is added sodium hydroxide solution, keeps soaking with sodium hydroxide strength of solution 1～2%.
The present invention is directed to existing positive plate and change into the after washing method and have that water loss is big, pole plate is handled uneven problem and improved,, filter out a kind of workable, significant positive plate of water-saving result and change into the back purging method by experiment repeatedly.Positive plate after described method will change into is immersed in the low-concentration sodium hydroxide solution, by control concentration of sodium hydroxide solution and positive plate soak time, reaches the certain ionogen (H of reservation in positive plate
+) time, remove the inner unnecessary electrolytical purpose of pole plate, in storage process, keep the stability of pole plate to guarantee positive plate.The inventive method can be saved a large amount of tap water, reduce the sewage that production process produces, reduce enterprise cost, the comparative experiment shows, the motorcycle battery that the positive plate that cleans with the inventive method is manufactured and the dry-charged performance comparison of the store battery of existing method for cleaning positive making, not only obtain good dry-charged performance, but also obtained the good preservation performance.
Embodiment
Abandoning tradition positive plate of the present invention changes into the after washing method, and the positive plate after changing into is immersed in the low-concentration sodium hydroxide solution, makes H+ ion contained in the pole plate and the OH in the sodium hydroxide solution
-Ion generation neutralization reaction is to remove the inner unnecessary ionogen (H of pole plate
+), simultaneously by the control of naoh concentration and soak time, make the certain ionogen (H of reservation in the positive plate
+), in storage process, keep the stability of pole plate to guarantee positive plate, satisfy it stores specified amount in certain storage time electric energy, the i.e. property used after so not only having reduced that pole plate is dried and depositing charge loss of energy in the process but also satisfy the pole plate activation.Test shows, if soaking with sodium hydroxide liquid concentration is higher or the pole plate soak time is long partially, the plate face that can cause handling is neutral, and the positive plate plate face look after the processing is undesired, influences the initial stage discharge performance of battery; If soaking with sodium hydroxide liquid concentration is on the low side or the pole plate soak time is short partially, can cause the plate face meta-acid handled, pH tended to cause the passivation of positive plate less than 4 o'clock, influenced the dry-charged performance of battery.Control soaking with sodium hydroxide liquid concentration is 1～2%, soak time 2～6min suits, and after taking out from soak solution through the positive plate that soaks, surveying its plate face pH is 4～6, and acid content is about 30%.
Positive plate after the immersion takes out and send drying machine to carry out drying.The sodium hydroxide solution that had soaked pole plate recycles, and can add sodium hydroxide in this solution, to keep the concentration of soaking with sodium hydroxide liquid.
