DEG C, when drying 5~8 is small；6th stage used 65~70 DEG C of dryings, 10~14 it is small when；It is small to cure drying time 68~72 altogether
When.
Obviously, length of traditional polar plate solidification drying time, the steam consumption and energy usage of curing room are big, high energy consumption, production
Quality is poor, and battery cycle life is low, low production efficiency, the deficiency of effects of energy saving and emission reduction difference.
The content of the invention
The object of the present invention is to provide a kind of method of energy battery positive plate rapid curing drying, can significantly reduce just
The time of pole plate rapid curing drying, has features simple and practical process convenient, saves the production time, saving cost, good practical effect,
It is energy-saving, improve production efficiency, battery cycle life is high and the advantages of good product quality.
For this reason, the present invention uses multisection type low temperature and the mixing cured method of high temperature to the positive plate of storage battery, to storage battery
Positive plate use multisection type low temperature and the mixing cured method of high temperature, cure the early stage of drying to polar plate solidification dry environment using low
Warm high humidity, cures dry mid-term to polar plate solidification dry environment using hot and humid, cures the later stage of drying and polar plate solidification is dried
Environment uses the method to being at the uniform velocity dehydrated, and this method is：
(1) first segment is 45~50 DEG C of temperature, humidity 100%, when hardening time 6~8 is small；
（2）Second segment is 80 DEG C of temperature, humidity 100%, when hardening time 4 is small；
（3）3rd section is 45~55 DEG C of temperature, humidity 85%, when hardening time 6 is small；
（4）4th section is 45~55 DEG C of temperature, and wind speed is under conditions of 90%, when hydrofuge 4 is small；
(5) the 5th sections are temperature 60 C, when drying 3 is small；
（6）6th section is 65~70 DEG C of temperature, when drying 7~10 is small.
Currently preferred curing is：
(1) first segment is 46~49 DEG C of temperature, humidity 100%, when hardening time 7.2~8 is small；
（2）Second segment is 80 DEG C of temperature, humidity 100%, when hardening time 4 is small；
（3）3rd section is 47~53 DEG C of temperature, humidity 85%, when hardening time 6 is small；

(5) the 5th sections are temperature 60 C, when drying 3 is small；
（6）6th section is 68~70 DEG C of temperature, when drying 7 is small.
The optimal curing of the present invention is：
(1) first segment is 48 DEG C of temperature, humidity 100%, when hardening time 7 is small；
（2）Second segment is 80 DEG C of temperature, humidity 100%, when hardening time 4 is small；
（3）3rd section is 50~51 DEG C of temperature, humidity 85%, when hardening time 6 is small；
（4）4th section is 50~51 DEG C of temperature, and wind speed is under conditions of 90%, when hydrofuge 4 is small；
(5) the 5th sections are temperature 60 C, when drying 3 is small；
（6）6th section is temperature 70 C, when drying 7 is small.
Said structure design has reached the purpose of the present invention.
The present invention can significantly reduce the time of positive plate rapid curing drying, have features simple and practical process convenient, save
Production time, saves cost, and good practical effect is energy-saving, improves production efficiency, battery cycle life height and good product quality
The advantages of.
Specifically advantage is：
1st, the present invention is by rapid curing drying means, by polar plate solidification drying time from pervious 68~72 it is small when, contracting
Be short to 30~35 it is small when, not only save energy consumption, improve production efficiency, and it is main is improve battery performance.This hair
It is bright battery cycle life is improved more than 1 times.Lift the capacity 13% of battery.Production efficiency 50% is improved, saves energy consumption 55%.
2nd, the present invention change traditional low temperature and high relative humidity curing process and because hardening time it is long the drawbacks of.The present invention uses
Multisection type low temperature and high temperature are mixing cured, are conducive to four basic lead sulphates (3PbOPbSO4H2O) and four alkali formula sulphur of pole plate
The generation of lead plumbate (4PbOPbSO4H2O), forms thicker corrosion layer.So that the lead oxide of pole plate grid Surface Creation and
Lead oxide in lead plaster combines more firm；Then, drying process makes pole plate porosity equal using dewatering at the uniform velocity
It is even.
The purpose for curing the low temperature and high relative humidity of the early stage of drying is to control in lead plaster the evaporation rate of moisture and by curing room
Humidification, substantial amounts of oxygen is provided to curing room, and the oxygen in water is to that can realize the oxidation of metallic lead, lead plaster and the corrosion of grid
It is used as Medium Diffusion to inside pole plate with reference to waiting chemical reaction, it is necessary to water oxygen catalysis is completed, and by moisture film, realizing
Oxidation corrosion.
Cure the generation that dry mid-term high temperature and heavy wet solidification is conducive to four basic lead sulphates (4PbOPbSO4H2O), this
The pole plate of sample generation is firmly combined with, battery cycle life length, while hot and humid in the short time will not be to the consistent of pole plate
Property has an impact.
It is the process that pole plate is at the uniform velocity dehydrated to cure the later stage of drying, and the pore-size distribution of such pole plate is uneven, is conducive to
The formation of porous electrode, lead plaster are combined with the hardening of grid in lead plaster.
The present invention uses rapid curing drying process, solves the structure of the basic lead sulphate in lead plaster, improves pole plate
Intensity, shorten hardening time, improve and production efficiency and meet the policy of national energy-saving emission reduction.
