Description
Technical field
It is low more particularly, to a kind of lead-acid battery negative pole plate low temperature the present invention relates to lead-acid accumulator manufacturing technology field
Moisture cure processes.
Background technology
The pole plate that the curing of pole plate refers to coat cream is under the conditions of certain temperature and time etc., in lead plaster gelatinization
The oxidation of completion free lead and grid rib surface lead and the recrystallization of basic lead sulphate and the process of hardening.In consolidating for pole plate
Change in drying process, with the progress of the mass transport process of evaporation water, do not allow to destroy its net structure；Meanwhile in moisture evaporation
Before finishing, it is necessary to complete oxidation and the 3PbOPbSO of metallic lead4·H2 The crystallization process of O.Therefore, in selection curing process
When, it should strictly control 3 solidification temperature, relative humidity and hardening time parameters.Several effects in solidification process are mutually to interconnect
System, no matter which kind of effect is not reaching to, and cured effect all will not be fine, influences capacity and the service life of battery.
For example, the Chinese patent of 104064734 A of data of publication of application 2014.09.24, application publication number CN discloses one
Technique for solidifying lead acid battery polar plate is planted, increases by one 80 ~ 82 DEG C of hot setting stage in the technique solidification process, continues
40 ~ 50min, and the hot setting stage arrangement is after low-temperature setting and before the intermediate temperature setting in later stage；Pole plate applies
Humidity is quickly transferred to after piece up in more than 95% curing drying shed.The technique is disadvantageous in that, in higher temperature,
Sulfate is with 4PbOPbSO4Form exists, compared with 3PbOPbSO4·H2For O, in charging formation process, it is difficult to
It is converted into the higher U-PbO of activity2, and T-PbO2 is easily generated, although the high mechanical strength of pole plate, its initial capacity is low, puts
Poor electrical performance.
The content of the invention
The present invention is long in order to solve the polar plate solidification time of the prior art, the problem of high energy consumption, discharge performance is poor, is provided
A kind of processing step is simple, and workable, hardening time is short, and low energy consumption, metal lead content is low in pole plate, solidification effect
It is good, the excellent acid accumulator negative plate low temperature and low humidity curing process of discharge performance.
To achieve these goals, the present invention uses following technical scheme：
A kind of lead-acid battery negative pole plate low temperature and low humidity curing process, comprises the following steps：
（1）First stage：The negative plate for drenching good acid is placed in curing room, control cures 40 ~ 45 DEG C of room temperature, relatively wet
Degree 70 ~ 80% cures 1 ~ 3h.Mainly make the still unstabilized basic lead sulphate recrystallization that conjunction cream is formed in this stage, improve activity
Cohesive force between material particle makes lead plaster substance form firm colloid net structure, and completes grid member oxidation, free lead
Partial oxidation.
（2）Second stage：Control cures 50 ~ 55 DEG C of room temperature, and relative humidity 50 ~ 60% cures 1 ~ 3h.This stage is main
Basic lead sulphate recrystallization is completed, accelerates oxidation process, electrode plate grid rate of corrosion is improved, further reduces free lead content.
（3）Phase III：Control cures 60 ~ 65 DEG C of room temperature, and relative humidity 40 ~ 50% cures 6 ~ 8h.The stage is very
It is important, it is important to which that heat up moisturizing, and relative humidity is down to 40 ~ 50%, and heating so that water evaporation rate becomes faster in pole plate, aoxidized
Journey is accelerated, and liberated heat is big, and with the progress of oxidation, its oxidation rate increasingly slows down, and is to reach lead plaster to send out because grid aoxidizes
The degree of balance of hot dehydration and steam moisturizing in curing room, makes the slow dehydration of green plate, should should continuously decrease relative humidity, otherwise
It is light then cause pole plate crackle, plate active material loose, make the service life reduction of pole plate, it is heavy then cause plate shelling accumulator short-circuit
It scraps.
（4）Fourth stage：Control cures 60 ~ 65 DEG C of room temperature, and relative humidity≤10% cures 10 ~ 12h.The stage is main
The evaporation rate of lead plaster moisture content is controlled, to ensure that colloid net structure is progressively transitioned into dry state by hygrometric state, and makes grid surface rotten
Degree of corrosion is further strengthened, and pole plate free lead content progressively drops to process value.
Preferably, step（1）In, curing room temperature 45 C is controlled, relative humidity 80% cures 2h.
Preferably, step（2）In, control cures 55 DEG C of room temperature, and relative humidity 60% cures 2h.
Preferably, step（3）In, control cures 65 DEG C of room temperature, and relative humidity 50% cures 8h.
Preferably, step（4）In, control cures 65 DEG C of room temperature, and relative humidity≤10% cures 12h.
Therefore, the invention has the advantages that：Curing process is optimized, processing step is simple, can grasp
The property made is strong, and by strictly controlling humidity and temperature, the curing of negative plate, solidification effect can be realized in low temperature and low humidity conditions
Good, hardening time greatly shortens, and energy consumption substantially reduces, and obtained anode plate intensity is good, and metal lead content is low, discharge performance
It is excellent.
