Description
Technical field
The invention belongs to polar plate of lead acid storage battery and manufacture field, be specifically related to a kind of polar plate of lead acid storage battery
Curing process.
Background technology
Lead-acid accumulator generally comprises positive plate, negative plate, dividing plate, electrolyte, bus-bar, positive pole
Post and negative terminal, wherein positive plate, negative plate are the core components of accumulator.The tradition system of pole plate
After making process the most first use Hydrocerussitum (Ceruse) and dilute sulfuric acid and additive mixing, full-filling is in grid surface, then carries out
Normal temperature cure is dried.Pole plate is during solidification, and metallic lead aoxidizes further and generates the same of lead oxide
Time also form tribasic lead sulfate and a certain proportion of four basic lead sulphates, the pole plate solidified is at plate
Grid surface corrosion becomes lead oxide, enhances the binding ability of grid muscle and active substance.
Green plate solidification is a highly important operation during lead-acid storage battery production, controls well solid
Change the key that room temperature, relative humidity and hardening time are green plate curing process.If these ginsengs
Number control not yet in effect, will be difficult to obtain three alkali of optimal proportion in the active substance in green plate after solidification
Formula lead sulfate and four basic lead sulphate mixture.The accumulator that conventional curing process manufactures is in the process of use
In there is pole plate premature capacity loss, positive plate softens, loose, and active material utilization presents random
The defects such as change, affect battery life.
For this problem, many producers propose high temperature curing process technology.Existing curing process
In, it is usually first solidification 26～48h, then is dried about 20h, solidify and be dried in same indoor complete
Become.
It is internalized into pole plate as Chinese patent literature that notification number is CN 103151499 A discloses one
Curing process, this curing process includes: A positive plate curing process: 1) the solidification first stage, temperature
Spend 35～38 DEG C, humidity 98～99%, the time 1～4h；2) solidification second stage, temperature 40～45 DEG C,
Humidity 98～100%, time 24h；3) the solidification phase III, temperature 55 DEG C, humidity 90%, time
Between 16h；4) it is dried first stage, temperature 65 DEG C, humidity 60～65%, time 10h；5) dry
Dry second stage, temperature 70 C, humidity 10%, time 16h；B negative plate curing process: 1)
The solidification first stage, temperature 35～38 DEG C, humidity 98～100%, the time 1～4h；2) solidification second
Stage, temperature 40～45 DEG C, humidity 97～99%, time 24h；3) solidification phase III, temperature
55 DEG C, humidity 90%, time 16h；4) it is dried the first stage, temperature 60 C, humidity 60～65%,
Time 12h；5) it is dried second stage, temperature 70 C, humidity≤10%, time 18h.
Chinese patent literature if notification number is CN101908622 B discloses a kind of power lead-acid
The curing process of accumulator plate, this curing process includes: (1) first stage: temperature 70～80 DEG C,
Humidity >=98%, oxygen content >=19%, the time 3～10h；(2) second stage: temperature 35～40 DEG C,
Humidity >=98%, oxygen content >=17%, the time 20～35h, then it is warming up to 50～55 DEG C of solidifications 1～8
h；(3) phase III: temperature 80～90 DEG C, humidity≤10%, the time 20～30h.
Existing high temperature curing process is disadvantageous in that, (1) solidifies and is dried in same indoor complete
Becoming, there is larger difference in the humiture when humiture at the end of cure stage and drying stage initiate,
The stability of pole plate can be affected when same indoor complete the conversion of this humiture；(2) solidification work
Skill complete after on pole plate the bond strength of active substance the highest, service life is short；The storage battery manufactured
Tankage is low.
Summary of the invention
The invention provides the curing process of a kind of polar plate of lead acid storage battery, utilize this curing process to make
Pole plate, on pole plate, the bond strength of active substance is high, and service life extends.
The curing process of a kind of polar plate of lead acid storage battery, including solidifying and being dried, described solidification is wrapped successively
Include with the next stage:
(1) first stage: temperature 54～56 DEG C, 25～35min under conditions of humidity 100%, are solidified；
(2) second stage: temperature 74～76 DEG C, solidifies 5.5～6.5 under conditions of humidity 98～100%
h；
(3) phase III: temperature 64～66 DEG C, 50～70 under conditions of humidity 97～99%, are solidified
min；
(4) fourth stage: temperature 58～62 DEG C, solidifies 9.5～10.5 under conditions of humidity 97～99%
h；
In (5) the 5th stages: temperature 51～53 DEG C, under conditions of humidity 94～96%, solidify 18.5～19.5
h；
In (6) the 6th stages: temperature 49～51 DEG C, under conditions of humidity 84～86%, solidify 8～9h；
In (7) the 7th stages: temperature 47～49 DEG C, under conditions of humidity 64～66%, solidify 4～5h；
In (8) the 8th stages: temperature 39～41 DEG C, under conditions of humidity 49～51%, solidify 50～70
min。
The present invention uses high temp. sectional formula curing process to solidify pole plate, in the 5th stage of solidification
Complete the metallic lead conversion to lead oxide, obtain tribasic lead sulfate and the four alkali formulas of optimal proportion simultaneously
Lead sulfate mixed crystal.Scanning electron microscopic observation finds, crystal grain size is homogeneous, acicular crystal ratio
Higher and be evenly distributed, agglomerate is few, and porosity is high, it can be seen that significantly framing structure.The 5th
After stage, solidification temperature and humidity are gradually lowered, so as between cure stage and drying stage
Transition stage, when preventing from having solidified, to proceed to humiture from the too high environment of humiture relatively low for pole plate
Dry environment causes water vapour moment at short notice in pole plate run off, the stability of pole plate is made
Become impact.
As preferably, described solidification included successively with the next stage:
(1) first stage: temperature 55 DEG C, 0.5h under conditions of humidity 100%, is solidified；
(2) second stage: temperature 75 DEG C, solidifies 6h under conditions of humidity 99%；

(8) the 8th stages: solidify 1h under conditions of temperature 40 DEG C, humidity 50%.
Solidification process should ensure that air supply, in order to be converted into lead oxide for metallic lead and provide required
Oxygen.Generally, as long as oxygen content is not less than content of oxygen in air in curing environment
90%, specifically can be according to actual production conditions depending on.In the present invention, solidification process keeps oxygen
Gas content >=19%.
It is dried after having solidified.In the present invention, described solidification and be dried respectively in different indoor
Carry out.I.e. solidify in curing room, be dried in pole plate is proceeded to after having solidified hothouse.
So be conducive to improving drying stage dehumidifying effect, preferably form the hole formed because of moisture evaporation,
Be conducive to improving the adhesion of active substance simultaneously, improve the intensity of pole plate.
As preferably, described being dried included successively with the next stage:
(1) first stage: temperature 64～66 DEG C, 2～3h under conditions of humidity 49～51%, it are dried；
(2) second stage: temperature 68～72 DEG C, is dried 2.5～3.5 under conditions of humidity 28～32%
h；
(3) phase III: temperature 74～76 DEG C, 50～70min under conditions of humidity 8～12%, it are dried；
(4) fourth stage: temperature 78～82 DEG C, humidity is to be dried 5.5～6.5h under conditions of zero；
