Abstract
The invention discloses a process for producing an accumulator plate. The process comprises the following steps: (1) filling lead plaster on a grid, and immersing through dilute sulphuric acid; (2) performing surface drying in advance, and spraying deionized water; (3) and performing curing treatment on the plate in a drying room, wherein an air inlet door is increased in the curing process so as to increase oxygen supply in the drying room, and the humidity in the drying room is kept to be 85-99 percent. According to the production process, the surface is dried in advance for spraying deionized water before curing, so that the curing time can be shortened, the surface of the plate can be prevented from cracking, and the quality of the plate is improved.
Description
?
Technical field
The invention belongs to lead accumulator technical field, relate in particular to the production of battery pole plates.
Background technology
At present, battery polar plate solidification technique life period is longer, and the situation that energy waste is larger has seriously restricted production cycle and the cost of storage battery; There is the inconsistent situation of dehydration in the pole plate in drying room simultaneously, and because dehydration is inhomogeneous or too fast, easily cause pole plate crack of surface layer, greatly affects pole plate quality.
By changing the flow direction of air-flow in drying room and the consistency that improves the upper and lower temperature of drying room, can improve polar plate solidification quality; And the floating powder of positive plate is more, by improving, can obviously reduce floating powder on surface of positive plate.。
Summary of the invention
Goal of the invention: for the problem and shortage of above-mentioned existing existence, the object of this invention is to provide a kind of accumulator pole board production technology, can prevent that pole plate cracking from reducing floating powder on surface, thereby guarantee pole plate quality.
Technical scheme: for achieving the above object, the present invention by the following technical solutions: a kind of accumulator pole board production technology, comprises the following steps: (1) first by lead plaster full-filling on grid, and embathe through dilute sulfuric acid; (2) then in advance after dry tack free, then Air washer; (3) then pole plate is delivered to drying room is cured processing, sets up shutter and improve oxygen-supplying amount in drying room in solidification process, keeps the interior humidity of drying room 85%～99% simultaneously.
The pole plate that full-filling is good sprays after dilute sulfuric acid, and through dry tack free, one makes pole plate lose part moisture, reduces curing time; It two increases the lead sulfate of polar board surface and inner basic lead sulphate adhesion, reduces possibility coming off, thereby reduce polar board surface, floats powder.Polar board surface Air washer after dry tack free, prevents that pole plate from continuing quick dehydration.
Beneficial effect: compared with prior art, the present invention has the following advantages: before solidifying, dry tack free is carried out deionized water spray in advance, both can shorten curing time, can also prevent polar board surface cracking, improves pole plate quality.
Embodiment
Below in conjunction with specific embodiment, further illustrate the present invention, should understand these embodiment is only not used in and limits the scope of the invention for the present invention is described, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present invention.
A board production technology, the pole plate that full-filling is good drenches acid through dry tack free, and one makes pole plate lose part moisture, reduces curing time; It two increases the lead sulfate of polar board surface and inner basic lead sulphate adhesion, reduces possibility coming off, thereby reduce polar board surface, floats powder.Polar board surface Air washer after dry tack free, prevents that pole plate from continuing quick dehydration.
Pole plate through skin drying hangs on the pole plate frame designing, and enters drying room proper alignment.
The turnover air door increasing has improved the oxygen-supplying amount of drying room, the reduction of pole plate lead content is played to remarkable effect, therefore shortened curing losing time, the hot and humid time is constant, drying stage increases the frequency of blower fan, accelerates the dry of pole plate, and whole curing dry run is at 48h.The switching of turnover air door is subject to the control of temperature humidity in drying room, and temperature drift is opened shutter, the higher air door of opening out of humidity, and drying stage turnover air door is all opened.
The motor 5 that stirs air formation air-flow in drying room moves always, the circulation stirring in drying room of the air-flow in drying room, and the air-flow that upper strata temperature is high moves to low layer, and the air-flow that lower floor's temperature is low moves to high level, plays the object that upper and lower temperature is consistent.During drying room temperature drift, shutter 1 is opened, the air intake drying room of outside, and drying room humidity goes out air door 2 when bigger than normal opens, and inner unnecessary humidity is drained.
Because the flow direction to air-flow is controlled, air-flow flows through from hanging on the space of the levels pole plate pole plate frame, has avoided the too fast phenomenon of tuyere position pole plate dehydration, and the pole plate dehydration of drying room inside is tending towards evenly, has improved the curing quality of pole plate.
In actual moving process, cause for some reason vapor pressure low and cause drying room temperature present situation on the low side, electric boiling plate 6 now can be started working, and makes up that steam pressure is not enough and the drying room temperature phenomenon on the low side that causes plays an important role to the reliability service of drying room.Drying room when operation, shower humidification, steam humidification, steam fin, electric boiling plate collaborative work, four have a damage, the drying room reliability service that can remain unchanged.
