Description
Technical field
The invention belongs to accumulator plate preparing technical field, is dried more particularly to a kind of solidifying lead acid battery polar plate
Technique.
Background technology
Curing process is process extremely crucial together during lead-acid storage battery production.Pole plate, after the completion of coating
Curing room is sent to be solidified.Solidifying lead acid battery polar plate is a physical change and electrochemical corrosion course, and its effect is
The hardening and corrosion of lead plaster are completed, allows being further oxidized to as lead monoxide of free lead in lead plaster, while allows lead plaster and grid
Between react and be combined as a whole, so as to reach the purpose of good mechanical strength and electrical property.So polar plate solidification is good
Bad overall performance and the life-span for being directly connected to pole plate.The solidification drying of green plate is in polar plate of lead acid storage battery manufacturing process
One of critical process, it directly influences the mechanical strength and electrical property of pole plate after chemical conversion complexity, chemical conversion, is related to plumbic acid
The amount of capacity and life-span length of battery.So the solidification process of the green plate after filling can not adopt a casual attitude；Polar plate solidification
Drying process is exactly the pole plate for scribbling wet cream, under high humidity and certain temperature, makes moisture evaporation in pole plate, and makes to send out in wet cream
Raw some changes, last wet pole plate turns into the green plate for having some strength to dry, for follow-up processing.
The content of the invention
It is an object of the invention to provide a kind of solidifying lead acid battery polar plate drying process, heated up by staged,
Cure stage temperature early stage rises slow, avoids that lead plaster dehydration is too fast to cause pole plate to ftracture；And by keeping in curing room
Relative humidity, it ensure that free lead oxidation and the heat humidity needed for grid corrosion, accelerated oxidation, the good corruption of forming properties
Layer is lost, connection is provided to solidify the skeleton of lead plaster, improves polar plate solidification quality.
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 solidifying lead acid battery polar plate drying process, is comprised the following steps：
Step 1：Cure stage
The a first stage：By curing room temperature control at 35 DEG C -40 DEG C, then relative humidity control is put pole plate 90%
In solidifying 5h in curing room；
B second stage：Solidification indoor temperature is improved to 50 DEG C -65 DEG C, relative humidity in 2h and is down to 70%, then will
Pole plate continues to solidify 7h；
The c phase IIIs：Solidification indoor temperature is improved to 70 DEG C -80 DEG C, relative humidity in 5h and is down to 45%, then will
Pole plate continues to solidify 10h；
Step 2：Drying stage
The a first stage：Solidification indoor temperature is improved to 75 DEG C, relative humidity in 4h and is down to 20%, then by pole plate
Continue to dry 18h；
B second stage：Solidification indoor temperature is improved to 90 DEG C, relative humidity in 5h and is down to 5%, then by pole plate after
It is continuous to dry 25h.
Further, the positive plate lead paste free lead content after the solidification is less than 3%；Negative plate lead after the solidification
Cream free lead content is less than 5%.
Further, the curing schedule first stage temperature uniformly slowly rises, temperature lifting per hour 1 in the stage
℃。
Further, the moisture of the positive plate after the solidification and negative plate is respectively less than 0.5%.
Further, in the solidification and drying process, temperature error≤± 1.5 DEG C, relative humidity deviation≤±
1.5%.
The invention has the advantages that：
The present invention is heated up by staged, rises in cure stage temperature early stage slow, avoids that lead plaster dehydration is too fast to be led
Cause pole plate cracking；And by keeping the relative humidity in curing room, it ensure that free lead oxidation and the heat needed for grid corrosion
Individual humidity, accelerated oxidation, the good corrosion layer of forming properties, connection is provided to solidify the skeleton of lead plaster, pole plate is improved and consolidates
Change quality.
Certainly, any product for implementing the present invention it is not absolutely required to reach all the above advantage simultaneously.
