Description

A kind of accumulator anode board curing process

Technical field

The invention belongs to storage battery production technical field, and in particular to a kind of accumulator anode board curing process.

Background technology

In lead-acid storage battery production field, green plate solidification is the highly important work of lead-acid storage battery production process Sequence, green plate solidification are the processes of a moisture evaporation, and in this process, the change of existing physics has the change of chemistry again, Therefore it is highly important that green plate controls curing process parameter.

The content of the invention

The purpose of the present invention is that overcome the deficiencies in the prior art and provides a kind of accumulator anode board curing process.

The purpose of the present invention is realized with following technical proposals：

A kind of accumulator anode board curing process, comprises the following steps：

1）Solidify the first stage：Under sealed environment, 70-78 DEG C of keeping temperature, humidity 90-99%, time 5-7h, during which Circulate wind speed 0.3-1 m/s；

2）Solidify second stage：Equally in a sealed meter environment, 30 DEG C~60 DEG C of temperature, humidity 80%~90% and holding 10~ The 40h times, during which circulate the m/s of wind speed 0.3~1；

3）Solidify the phase III：Temperature 70 C~90 DEG C, humidity 5%~10% are simultaneously kept for 5~10h times, during which circulated air 4~8 m/s of speed；

Wherein, at 180~360 minutes, remaining was controlled the control of second stage conversion used time phase III per the phase transition time System was at 60~240 minutes.

The solidification first stage reaches 45-50 DEG C of temperature, humidity 100% when curing room environmental condition, and pole plate initially enters solidification Room, thus condition change to solidification first stage environmental condition time into 60~240 minutes.

It is 4 that the solidification phase III, which controls the ratio of other materials in four basic lead sulphates and pole plate,：6.

The solidification phase III need to augment oxygen by being atomized waterpipe, and oxygenating mode is that oxygenating 30S stops 10min, every time Oxygenating amount of oxygen is 0.5-2m³。

The present invention by repeatedly scientifically and rationally testing, final optimization pass positive plate cure stage temperature, humidity, the time and Wind speed parameter is circulated, the high-performance of grid is ensure that, further increases battery quality, obtained using curing process of the present invention Battery, its performance parameter are as follows：

Battery life：Reach 460 positive lead plasters of 100%DOD not soften；

Cryogenic property：Under 115 minutes/- 15 DEG C environment；

Grid corrosion thickness reaches 10~40 μm of

12 times/1 meter height of plate strength, degeneration rate≤1%；

Heavy current discharging time：3.6I2（A）Current discharge terminates when to accumulator voltage being 10.5V, and discharge time >= 30 minutes, beyond national standard 50%.

Embodiment

Embodiment 1

A kind of accumulator anode board curing process provided by the invention, comprises the following steps：

1) pole plate interior humidity is 95% before pole plate enters curing room, temperature 60 C；When curing room environmental condition reaches temperature 45-50 DEG C, humidity 100%, pole plate initially enters curing room；

2) first stage is solidified：Take 60~240 minutes by step 1 and make curing room environmental condition reach humidity 90%~ 99%, temperature 70 C~78 DEG C, i.e. slowly heating；And 5~7h of this environment is kept, because first section uses hot and humid technique, faster Speed makes crystal excessively tiny inside lead plaster fully burn, and generates larger sulfuric acid leading crystal, while activate graphite in lead plaster Dissolved under hot and humid environment with lead plaster, generate aperture；Blast velocity control makes wet at air port in 0.3~1 m/s simultaneously Degree plays inlet and outlet, humidity unanimously acts on not by air speed influence；

3) second stage is solidified：Humiture goes to 30 DEG C~60 DEG C of temperature by solidifying first stage condition, and humidity 80%~ 90%, it is desirable to slowly decline, used time 60~240 minutes when being finally reached this demands, then keep 10~40h times constant, Because humidity set is relatively low, polar board surface lead plaster is set to be lost in a part of moisture content so as to generate the lead plaster of some strength, simultaneously because Humiture reduces, and pole plate internal moisture can outwards volatilize, and free lead conversion and grid corrosion is first entered from inside for next stage Row lays the first stone, and this stage mainly solves floating powder on surface, and wind speed keeps the constant uniformity for solving to bring due to air quantity change Difference；

4) phase III is solidified：Humiture goes to temperature 70 C~90 DEG C by solidification second stage condition, and humidity 5%~ 10%, it is desirable to which temperature slowly rises and humidity slowly declines, and is finally reached this demands used time 180~360 minutes, and keeps 5 ~10h the times, due to this phase sets high temperature low humidity, internal free lead is set faster to aoxidize, so as to reach corrosion grid Effect, while high temperature wet down technique is used, during which due at this moment can in the first stage using caused larger crystal after high temperature Four more basic lead sulphates are generated, time control main purpose is control four basic lead sulphate amounts of generation and pole plate other materials Amount（Predominantly tribasic lead sulfate, basic lead sulphate, lead oxide, moisture etc.）Ratio 4:6, now for oxidation reaction it is most when Wait, it is necessary to oxygen also increase as, when bringing into operation in this stage, atomization waterpipe stops the side of 10 minutes with oxygenating 30S Formula carries out supplement oxygen, and each oxygenating amount of oxygen is 0.5-2m³；The m/s of wind speed 4~8, main function are oxidizing process to be taken away In caused waste heat, make the consistent purpose of temperature is presented between grid and lead plaster.

Embodiment 2

1) pole plate interior humidity is 95% before pole plate enters curing room, temperature 60 C；When curing room environmental condition reaches temperature 50 DEG C of degree, humidity 100%, pole plate initially enters curing room；

2) first stage is solidified：Taking 70 minutes by step 1 makes curing room environmental condition reach humidity 91%, temperature 77 DEG C, i.e. slowly heating；And this environment 5h is kept, while blast velocity control is in 0.5 m/s；

3) second stage is solidified：Humiture goes to 35 DEG C of temperature, humidity 80% by solidifying first stage condition, it is desirable to slowly Decline, used time 240 minutes when being finally reached this demands, then keep the 12h times constant, the m/s of wind speed 0.5；

4) phase III is solidified：Humiture goes to 80 DEG C of temperature, humidity 6%, it is desirable to which temperature is delayed by solidification second stage condition Slow rise slowly declines with humidity, is finally reached this demands used time 200 minutes, and is kept for the 6h times, starts in this stage During operation, atomization waterpipe carries out supplement oxygen in a manner of oxygenating 30S stops 10 minutes, and each oxygenating amount of oxygen is 0.8m³； Wind speed 5m/s.

Each stage parameter of 3-20 positive plate curing process of the embodiment of the present invention is shown in Table 1-2.
