Process control is bad, and the plate active material solidified will can not produce the 3BS (tribasic lead sulfate) and 4BS of optimal proportion
(four basic lead sulphates) mixture.And the battery manufactured using conventional curing process is deposited and occurs pole plate in use
The defects of premature capacity loss, positive plate soften, are loose, and random change is presented in active material utilization, influences battery life.Pin
To this problem, many producers are in researching high-temperature curing process technology, but the battery produced using current prior art is not
The requirement that battery initial capacity is big and battery cycle life is high can be met simultaneously.
A kind of currently designed polar plate solidification technique prepared for accumulator plate, is cooled by stepped temperature raising, carried
High 4BS conversion ratio, improves accumulator plate quality, by the reciprocal fluctuation of relative humidity, effectively prevent pole plate and be heated
Inequality causes lead plaster to ftracture or come off.
The content of the invention
It is an object of the invention to provide a kind of polar plate solidification technique prepared for accumulator plate, by stepped
Temperature raising cools, and improves 4BS conversion ratio, obtains more preferably adhesion strength between lead plaster and grid surface, and by humidity and
The reciprocal fluctuation-type of temperature reduces, and effectively prevent pole plate uneven heating causes lead plaster to ftracture or come off, and improves accumulator pole
Plate quality, improve service lifetime of accumulator.
In order to solve the above technical problems, the present invention is achieved by the following technical solutions：
The present invention is a kind of polar plate solidification technique prepared for accumulator plate, is comprised the following steps：
First stage：In the low-temperature moisture preservation stage, pole plate is placed in the bar that temperature is 35 DEG C -60 DEG C, relative humidity is 100%
Solidify 8 hours under part；
Second stage：The high temperature moisturizing stage, by pole plate be placed in temperature be 60 DEG C -80 DEG C, relative humidity be not less than 92%
Under conditions of solidify 15 hours；
Phase III：The high temperature drying stage, by pole plate be placed in 70 DEG C -85 DEG C, relative humidity be 90%-20% under conditions of
8 hours；
Fourth stage：The middle temperature is dried stage, by pole plate be placed in 40 DEG C -60 DEG C, relative humidity be not higher than 15% under conditions of
19 hours；
After the completion of the middle temperature is dried stage, stop heating, and discharge hot-air by the near room temperature of temperature by exhaust blower.
Further, the low-temperature moisture preservation stage 35 DEG C -40 DEG C keep 3 hours after by temperature rise to 40 DEG C -50 DEG C guarantor
Hold 3 hours, then temperature is risen to 60 DEG C and kept for 2 hours.
Further, relative humidity fluctuates between 100%-92% in the high temperature moisturizing stage, first slowly reduces again
Rise, then reduce, relative humidity is down to 92% several times for reciprocal fluctuation.
Further, the high temperature drying stage relative humidity slowly reduces, then rises, then reduces, and back and forth fluctuates some
Secondary relative humidity is down to 20%.
Further, relative humidity is slowly down to less than 5% by the low temperature drying stage by air blower.
Further, the solidification room temperature is controlled by electric heating system；Relative humidity is sprayed by atomizing humidifying performance
Head and steam humidification and exhaust blower control；Curing room both sides there is also mounted some air blowers and be used for air intake.
The invention has the advantages that：
The present invention is cooled by stepped temperature raising, is improved 4BS conversion ratio, is obtained more between lead plaster and grid surface
Good adhesion strength, and reduced by the reciprocal fluctuation-type of humidity and temperature, effectively prevent pole plate uneven heating causes lead plaster
Ftracture or come off, improve accumulator plate quality, improve service lifetime of accumulator.
Certainly, any product for implementing the present invention it is not absolutely required to reach all the above advantage simultaneously.
