Abstract
The invention relates to the field of production of a storage battery, in particular to a curing and drying process for a positive electrode of a lead-acid storage battery. The curing and drying process comprises three stages of curing, standing and drying, in a curing stage, the electrode plate is in close contact, the temperature in the curing stage is set to be 55 to 60 DEGC, the curing humidity is set to be 90-98%, and the curing time is set to be 12 to 24 hours; in a standing stage, the time is set to be 8 to 12 hours, and oxygen in air is absorbed into the interior of the electrode plate during the slow cooling process of the electrode plate so as to realize a condition required for free lead conversion; and in the drying stage, the temperature is set to be 60 DEG C, the drying humidity is set to be blew 30%, and the drying time is set to be 20 hours. By the curing and drying process, the effect of high-temperature curing can be achieved on the condition of a relatively low curing temperature, and energy consumption and cost are reduced.
Description
Technical field
The present invention relates to the production technology field of storage battery, specifically a kind of curing and dying process of anode plate for lead acid accumulator.
Background technology
Make lead-acid battery process in, in lead-acid battery positive plate lead paste unconverted free lead and moisture too high, need to be cured drying and make it drop to lower level, free lead drops to less than 4%, and moisture drops to less than 1%.Concrete technology flow process is as follows: 1 and cream; 2, coated plate; 3 wet positive plates; 4, solidification, drying; 5, dry positive plate.The curing process of current lead-acid battery positive plate has hot setting and normal temperature cure two kinds, and hot setting temperature is 75 ~ 90 DEG C, and humidity is 90 ~ 98%; Normal temperature cure temperature is 40 ~ 50 DEG C, and humidity is 90-98%.In drying process, baking temperature is 60 ~ 90 DEG C, and humidity is less than 30%.Above-mentioned curing and dying process is all produce comparatively conventional curing and dying process at present.
Summary of the invention
For solving the technical problem of above-mentioned existence, the invention provides a kind of curing and dying process of anode plate for lead acid accumulator, under the condition of lower curing temperature, the effect of the solidification that reaches a high temperature, reduces energy consumption and cost.
For achieving the above object, the technical solution adopted in the present invention is:
A curing and dying process for anode plate for lead acid accumulator, is characterized in that, comprises solidification, static and dry three phases, in cure stage, by pole plate close proximity, cure stage design temperature is 55-60 DEG C, solidification humidity is set to 90-98%, and curing time is set to 12-24 hour; Quiescent phase set of time is 8-12 hour, pole plate in slowly cooling procedure, the oxygen in air is sucked pole plate inner with reach free lead transform needed for condition; Drying stage temperature is set to 60 DEG C, and dry humidity is set to less than 30%, is set to 20 hours drying time.
Anode plate for lead acid accumulator curing and dying process set forth in the present invention, mainly in cure stage by pole plate close proximity together, the heat utilizing pole plate self-heat generation to react is to improve the temperature in polar plate solidification stage, it is inner with the condition reached needed for free lead conversion that quiescent phase makes pole plate the oxygen in air be sucked pole plate in the process slowly cooled, and drying stage temperature only needs 60 DEG C, make the temperature of cure stage just can reach solidification 75-90 DEG C when 55-60 DEG C like this, the hot setting drying effect of dry 60-90 DEG C, decrease the energy resource consumption in whole technical process, reduce production cost, improve the economic benefit of enterprise.
Embodiment
Describe the present invention below in conjunction with specific embodiment:
Embodiment 1:
By positive plate close proximity, cure stage temperature is 55 DEG C, and solidification humidity is 90 ~ 98%; Quiescent phase 8 hours; Baking temperature is 60 DEG C, and dry humidity is less than 30%.Solidify 12 ~ 24 hours, the experimental result of dry 20 hours is as table 1:
Table 1
Embodiment 2:
By positive plate close proximity, cure stage temperature is 55 DEG C, and solidification humidity is 90 ~ 98%; Quiescent phase 12 hours; Baking temperature is 60 DEG C, and dry humidity is less than 30%.Solidify 12 ~ 24 hours, the experimental result of dry 20 hours is as table 2:
Table 2
Embodiment three:
By positive plate close proximity, cure stage temperature is 60 DEG C, and solidification humidity is 90 ~ 98%, quiescent phase 8 hours; Baking temperature is 60 DEG C, and dry humidity is less than 30%.Solidify 12 ~ 24 hours, the experimental result of dry 20 hours is as table 3:
Table 3
Embodiment four:
A curing and dying process for lead-acid battery positive plate, by positive plate close proximity, cure stage temperature is 60 DEG C, and solidification humidity is 90 ~ 98%, quiescent phase 12 hours; Baking temperature is 60 DEG C, and dry humidity is less than 30%.Solidify 12 ~ 24 hours, the experimental result of dry 20 hours is as table 4:
Table 4
As can be seen from above embodiment, pole plate has product four basic lead sulphate (4BS) of hot setting to generate after overcuring drying.Pole plate is closely drawn close in cure stage by the present invention, and the heat utilizing pole plate self-heat generation to react is to improve the temperature in polar plate solidification stage, thus the effect of the solidification that reaches a high temperature.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention is also not limited in above-mentioned citing, and the change that those skilled in the art make in essential scope of the present invention, remodeling, interpolation or replacement also should belong to protection scope of the present invention.
