Abstract
The invention discloses a curing and drying method applied to a lead-acid storage battery plate. The method comprises the step of: curing a pasted green plate in a quick surface drying stage, a normal temperature curing stage and a plate drying stage, wherein the curing conditions of the quick surface drying stage comprise temperature of 200 to 320 DEG C, time of 30 to 40 seconds and humidity of less than 20 percent; the curing conditions of the normal temperature curing stage comprise temperature of 50 to 85 DEG C, time of 5 to 10 hours and humidity of 85 to 99 percent; and the curing conditions of the plate drying stage comprise temperature of 70 to 85 percent, time of 15 to 17 hours and humidity of less than 20 percent. By the method, curing and drying time can be effectively saved, and generally, 20 to 21 hours are required for curing; a plurality of green plates can be seamlessly arranged directly adjacent to each other, so that a curing space is greatly enlarged, and curing efficiency is greatly improved; and the free lead content and water content of the plate are superior to those in the conventional method.
Description
Technical field
The invention belongs to lead acid accumulator production field, be specifically related to a kind of solidifying and drying method of polar plate of lead acid storage battery
Background technology
Green plate to solidify dry be one critical process in polar plate of lead acid storage battery manufacture process, it directly has influence on and changes into complexity, changes into mechanical strength and the electrical property of rear pole plate, is related to amount of capacity and the life-span length of lead acid accumulator.So the solidification process of the green plate after filling can not be adopted a casual attitude.
Polar plate solidification drying process is exactly the pole plate that scribbles wet cream, under high humidity and uniform temperature, makes water evaporates in pole plate, and makes, in wet cream, some variation occurs, and finally wet pole plate becomes the green plate that has some strength dry, for follow-up processing.
Chemical change in solidification process has: the metallic lead in lead plaster is further oxidized.With cream by the oxidizability of lead powder generally in 75%～85% left and right, with the process of cream in to understand some lead oxidized, and after cream, unoxidized lead is in 10% left and right, this part lead need to be oxidized gradually in curing process.Degree of oxidation plumbous in lead plaster is an outstanding feature of polar plate solidification quality, and the free lead content in lead plaster is below 3%, and moisture is below 2%.Plumbous oxidation and water content in lead plaster in lead plaster, curing temperature, solidification humidity, curing time, four factors were relevant.And high temperature (>=80 ℃) is solidified with the generation that is beneficial to 4BS (4PbOPbSO4), the cycle life that the pole plate after solidifying has lower initial capacity to become reconciled.No matter be hot setting or low-temperature setting, higher relative humidity is curing necessary condition.In production, often take complete curing (generally all more than 24h) curing time of growing, so that completion of cure is thorough.In solidification process, between every two pole plates, need to leave certain gap, be generally 2mm～4mm, this has greatly wasted the space of curing room.
Summary of the invention
The object of the invention is to provide on the basis of existing technology a kind of and can effectively reduce the solidifying and drying method that solidifies drying time, saves curing dry place.
Object of the present invention can reach by following measures:
Be applicable to a solidifying and drying method for polar plate of lead acid storage battery, the method comprises the green plate after filling is cured by accelerated surface drying stage, normal temperature cure stage and pole plate drying stage three phases:
The condition of cure of described accelerated surface drying stage is: 200 ℃～320 ℃ of temperature, and time 30s～40s, humidity is below 20%;
The condition of cure in described normal temperature cure stage is: temperature 50 C～85 ℃, and time 5h～10h, humidity is 85%～99%;
The condition of cure of described pole plate drying stage is: temperature 70 C～85 ℃, and time 15h～17h, humidity is below 20%.
The condition of cure of the accelerated surface drying stage in this method is preferably: 200 ℃～300 ℃ of temperature, and time 35s～40s, humidity is below 20%.More preferably 250 ℃～300 ℃ of temperature.
The condition of cure in the normal temperature cure stage in this method is preferably: temperature 50 C～80 ℃, and time 5h～10h, humidity is 85%～99%; More preferably 70 ℃～80 ℃ of temperature, the time is 5h～8h more preferably, humidity more preferably 90%～99%.
The condition of cure of the pole plate drying stage in this method is preferably: temperature 70 C～80 ℃, and time 16h, humidity is below 20%.
In the present invention, multiple pole plates are in normal temperature cure stage and pole plate drying stage, seamless putting between adjacent two pole plates.
The present invention there is no specific requirement to the active material filling on green plate and the method that fills, and this law is dried applicable to the solidifying of various pole plates of lead acid accumulator.
This solidifying and drying method can directly carry out in existing curing room or other conventional curing apparatus.
This method can effectively be saved and be solidified drying time, and general only to need 20～21h to complete curing, between multiple green plates, can directly be close to seamless putting, and very big has promoted curing space and efficiency, and pole plate free lead content and water content are also better than existing method simultaneously.
Embodiment
Pole plate take thickness as 1.5mm is example below, introduces this solidifying and drying method:
Just the green plate after multiple filling (conventional polar plate of lead acid storage battery negative plate) is put into curing room together, is cured as follows dryly, and randomly draws 5 pole plates wherein and numbers respectively 1-5 test.
Rapid curing phase temperature is 300 ℃, time 35s, humidity 10%; 80 ℃ of normal temperature cure phase temperature, time 5h, humidity is 95%, and drying stage temperature is 80 ℃, and the time is 16h, humidity 0%.At normal temperature cure stage and drying stage, between pole plate, adopt seamless putting.
Another part green plate of above-mentioned same batch is carried out to common solidifying and be dried, i.e. first normal temperature cure, drier.70 ℃ of normal temperature cure phase temperature, time 32h, humidity is 95%; Drying stage temperature is 80 ℃, and the time is 16h, humidity 0%.Randomly draw 1 pole plate wherein and be numbered 6 and test.
The results are shown in following table.
| Pole plate number | Free lead content: % | Moisture: % |
| 1 | 1.82％ | 1.05％ |
| 2 | 1.85％ | 1.03％ |
| 3 | 1.79％ | 1.04％ |
| 4 | 1.81％ | 1.05％ |
| 5 | 1.95％ | 1.03％ |
| 6 | 2.02％ | 1.99％ |
Space availability ratio: be dried than common solidifying, leaving gap between every pole plate is 2mm～4mm, and adopts the present invention, and pole plate can be put in this 2mm～4mm space, and the anode volume utilance of 1.5mm can promote more than one times.
Adopt the present invention, no matter from pole plate free lead content, water content or space availability ratio, more traditional curing drying mode all has greatly improved.
