Embodiment Construction

[0009] Below in conjunction with specific embodiment, further illustrate the present invention, should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various equivalent forms of the present invention All modifications fall within the scope defined by the appended claims of the present application.

[0010] A battery plate production process, the filled plate is dried with acid on the surface, firstly, the plate loses part of the moisture and reduces the curing time; secondly, the lead sulfate on the surface of the plate is combined with the basic lead sulfate inside The force increases, reducing the possibility of shedding, thereby reducing floating powder on the surface of the plate. After the surface is dry, spray deionized water on the surface of the plate to prevent the plate from continu...

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

[0001] technical field [0002] The invention belongs to the technical field of lead storage batteries, and in particular relates to the production of battery polar plates. Background technique [0003] At present, the battery plate curing process takes a long time and wastes a lot of energy, which seriously restricts the production cycle and cost of the battery; at the same time, the plates in the drying room have inconsistent water loss, and due to uneven water loss or If it is too fast, it is easy to cause cracks on the surface of the polar plate, which greatly affects the quality of the polar plate. [0004] By changing the flow direction of the air in the drying room and improving the temperature consistency of the upper and lower sides of the drying room, the curing quality of the plate can be improved; and the positive plate has more floating powder, and the improvement can significantly reduce the floating powder on the surface of the positive plate. .
