Abstract
The present invention discloses technology for manufacturing the pole plates of a lead-acid accumulator, particularly solidifying technology for raising the pressure, temperature and humidity of the pole plates of the lead-acid accumulator during solidification and shortening the solidifying time of the pole plates of the lead-acid accumulator from scores of hours to 1.5 to 2 hours. The technology has the steps: A, pole plates coated (1) with lead plaster are wrapped by cloth pieces or other fibrous materials and then enswathed by high temperature resisting rubber bands or other ropes and strips; B, the pole plates (1) are stacked in a solidifying box, the two polar plates (1) are separated by slab lattice (2) in a stacking process, every stack has four to eight pieces and 0.3 to 0.7kg of weight is pressed on the utmost upper one of the pole plates (1); C, the inner part of the solidifying box has the environment C1 of 170 to 230KPa of absolute pressure, 115 to 125 DEG C of Celsius temperature and 80 to 98% of relative humidity or the environment C2 of 250 to 360KPa of absolute pressure, 126 to 140 DEG C of Celsius temperature and 100% of relative humidity; D, the solidifying box starts to time and solidify for 90 to 120 minutes after reaching required environmental conditions; E, after solidifying time is over, the environment of the solidifying box slowly releases to normal temperature and pressure within 20 to 30 minutes; F, the pole plates after solidified are dried for 18 to 19 hours at the temperature of 70 to 90 DEG C.
Description
Technical field the present invention relates to the polar plate of lead acid storage battery manufacturing process.Particularly with the battery polar plate solidification time by the polar plate of lead acid storage battery manufacturing process that shortened to 1.5～2.0 hours in tens hours.
The background technology solidifying lead acid battery polar plate is a physical change and electrochemical corrosion process, its effect is the sclerosis of finishing lead plaster, the further oxidation of free lead and the corrosion of grid, thereby reach the purpose of excellent mechanical intensity and electrical property, solidifying lead acid battery polar plate adopts low-temperature setting (≤70 ℃) in normal pressure (1atm) more at present, grow (about 72 hours) its curing time, seriously restricting the production cycle of lead acid accumulator.
The summary of the invention the technical problem to be solved in the present invention is, avoids above-mentioned the deficiencies in the prior art part and proposes a kind of pressure, the temperature and humidity of polar plate of lead acid storage battery when solidifying that improve, and makes the curing that the polar plate solidification time shortens.
The physics chemical action process speeds up along with the raising of temperature and pressure within the specific limits, under the high pressure-temperature high humidity environment, the physical and chemical process of plumbous oxidation, the sclerosis of lead plaster and grid corrosion rate low temperature in the normal pressure, but too high pressure, temperature will be damaged polar plate of lead acid storage battery, therefore must select suitable pressure, temperature and humidity just can obtain satisfied effect.
The technical scheme that the present invention solve the technical problem employing comprises the steps:
A, the pole plate that will coat lead plaster encase with cloth sheet or other fiber materials, wrap with high-temperature resistant rubber band or other ropes, bar again;
B, pole plate are stacked and placed on and solidify in the case, when stacking, separate each folded 4 to 8 between the two-plate with grid; Press the weight of 0.3kg～0.7kg on the topmost pole plate;
Environment in C, the described curing case of control is:

D, pick up counting after case reaches the environmental condition of described requirement, solidified 90～120 minutes when solidifying;
After E, curing time had arrived, the environment that solidifies case slowly was released into normal temperature and pressure within 20～30 minutes;
F, the pole plate after solidifying under 70～90 ℃ temperature dry 18～19 hours.
Preferred plan comprises the steps:
A ', the pole plate that will coat lead plaster encase with cloth sheet or other fiber materials, wrap with rubber band again;
B ', pole plate are stacked and placed on and solidify in the case, when stacking, separate with grid between the two-plate, and each folds 6, press the weight of 0.5kg on the topmost pole plate;
Environment in C ', the described curing case of control is:
C1 ': absolute pressure: 198Kpa
Celsius temperature: 120 ℃
Relative humidity: 98%
Perhaps
C2 ': absolute pressure: 270Kpa
