Description
Technical field
The present invention relates to power lead-acid battery manufacturing technology field, especially relate to a kind of power lead-acid battery pole plate high temperature curing process.
Background technology
At present in electrokinetic cell field, the cycle life of battery is greatly about 300 left and right, user just need to change battery in use for about 1 year, causes the significant wastage of resource and battery can cause environmental pollution in removal process, affects the development in electrokinetic cell field.
In the manufacturing process of the battery of power, it to the operation having the greatest impact useful life, is the curing process of pole plate.Curing process is the critical process in lead acid accumulator production process, be about to grid through lead plaster fill, accelerated surface delivers to curing room after dry and is cured.The solidification process of pole plate is the process of physical change, electrochemical reaction and formation active material structure, thereby the quality of curing process directly affects the service life cycle that the quality of pole plate affects battery.
For example, Granted publication CN100585918C, the Chinese patent in January 27 2010 Granted publication day discloses a kind of curing and dying process of lead-acid battery green plate, comprise cure stage and drying stage, cure stage temperature is 55～70 ℃, solidification humidity is 90～98%, and be 0～12 hour curing time; Baking temperature is 55 ~ 70 ℃, and dry humidity is below 30%, and be 24 hours drying time.Although this curing and dying process has shortened the curing time of green plate, the poor bonding strength of lead plaster and grid, easily shedding, the active material structure obtaining is poor, causes the useful life of battery shorter.
Summary of the invention
The present invention is in order to solve the resulting pole plate lead plaster of polar plate solidification technique of prior art and the poor bonding strength of grid, easily shedding, the short problem of battery of making, provide a kind of processing step simple, workable, can optimize battery initial capacity, avoid pole plate at battery Shedding of Positive Active Mass between the operating period, improve the power lead-acid battery pole plate high temperature curing process of electrokinetic cell cycle life.
To achieve these goals, the present invention is by the following technical solutions:
A power lead-acid battery pole plate high temperature curing process, comprises the following steps:
(1) warm high humidity cure stage in: pole plate is sent into curing room, and controlling curing room temperature is 40 ~ 45 ℃, humidity >=99%, under this condition to polar plate solidification 4 ~ 6h.This stage is the primary solidification stage of pole plate, Main Function is the exchange of moisture content in the interior moisture content of balance and stable pole plate lead plaster and curing room, for hot setting provides necessary condition, in this stage, should be noted and control the heating-up time, can control curing room temperature and from room temperature, rise to 40 ~ 50 ℃ in 2 ~ 4h, to avoid grid temperature to raise too fast, cause the lead plaster rate-of-loss of coolant contacting with grid rib too fast, make to form between grid rib and lead plaster good corrosion layer.
(2) the high temperature and heavy wet solidification stage: controlling curing room temperature is 70 ~ 75 ℃, humidity >=99%, under this condition to polar plate solidification 6 ~ 8h.This stage is the core of pole plate hot setting, under hot and humid environment, make lead plaster generate four basic lead sulphates of a fixed structure and quantity, thereby form the skeleton of positive plate active material structure, strengthened the glue chain intensity between lead plaster, make to form good corrosion layer between lead plaster and grid rib simultaneously, improved and changed into the intensity of rear pole plate and avoid the softening and shedding of positive plate during battery, in this stage, can control curing room temperature and in 6 ~ 8h, rise to 70 ~ 80 ℃.
(3) warm high humidity cure stage in: controlling curing room temperature is 40 ~ 45 ℃, humidity >=99%, under this condition to polar plate solidification 6 ~ 8h.This stage is the follow-up phase of hot setting, object is stable and the lead plaster of balance after hot setting, avoided crossing of four basic lead sulphates to generate, guaranteed the initial capacity of battery, in this stage, can control curing room temperature and in 2 ~ 6h, drop to 40 ~ 50 ℃, more consistent to guarantee the temperature between lead plaster and grid, avoid polar board surface to produce through wall flaw.
(4) the moisturecuring stage in temperature in: control curing room temperature and maintain 40 ~ 45 ℃, humidity is 70 ~ 80%, under this condition to polar plate solidification 4 ~ 6h.The Main Function in this stage is by reducing solidification humidity, further promote the oxidation of free lead in lead plaster, and impel the combination between lead plaster and grid more firm, generally can in 2 ~ 4h, by >=99%, drop to 70 ~ 80% to avoid the poly-of moisture content in setting up period lead plaster so to decline by controlled humidity, make the interior physics of lead plaster and chemical reaction more abundant, avoid polar board surface to crack.
As preferably, in step (1), curing room temperature is controlled at 45 ℃, and be 6h curing time.
As preferably, in step (2), curing room temperature is controlled at 75 ℃, and be 6h curing time.
As preferably, in step (3), curing room temperature is controlled at 45 ℃, and be 8h curing time.
As preferably, in step (4), curing room humidity is controlled at 80%, and be 6h curing time.
Therefore, the present invention has following beneficial effect: pole plate is carried out to four stage solidification, processing step is simple, workable, by regulating curing temperature, humidity and the time in each stage, make whole solidify reaction process steadily controlled, can improve the bond strength between active material and grid and optimize the structure of plate active material, thereby optimize the initial capacity of lead-acid power accumulator, and effectively improve its useful life.
