Abstract
A procedure for producing pole plate includes steps: first, preparing metal sheet grating; manufacturing raw pole plates from sheet gratings; being installed into accumulator, raw pole plates are as chemical energy source to be activated; painting a layer of protective agent on plate ear of sheet grating after sheet grating being heated to 15-100 within 24 hours after sheet grating being produced; temperature of the protective agent is controlled at 180-80 deg.C. Boiling point of the protective agent is higher than temperature in each step of producing raw pole plates, and is lower than temperature when flow weld or burnt together are carried out between plate ear and bus bar. The said protective agent is prepared by using vacuum residue of microcrystalline wax as raw material through following steps: propane deasphalting, furfural refining, acetone-benzene dewaxing and deoiling, additional treatment of clay. Features are: high production rate, and preventing lead pollution.
Description
Technical field
The present invention relates to a kind of ears of pole plate method not oxidized in process of production and that do not attached of protecting storage battery by dirt.
Background technology
In the lead acid accumulator production industry, bus-bar is welded on the ears of pole plate.The effect of bus-bar is the electric current that chemical reaction on the pole plate produces to be pooled together offer outside electrical appliance use, perhaps distributes to pole plate from outside acquisition electric current storage battery is charged.Bus-bar serves as an effect that compiles the intermediate medium of electric current, is in very important link.
If welding is bad between bus-bar and the ears of pole plate, can have a strong impact on the performance of battery.More seriously,, cause resistance to increase, when high-rate battery discharge, might cause the hydrogen that produces by hydrolysis that accumulates in the long-term use of battery and the blast of oxygen mixture if there is false welding between bus-bar and the ears of pole plate.
Ears of pole plate is with plumbous and multiple metal alloy.In the process of making green plate, the surface of ears of pole plate is formed oxide layer by the dioxygen oxidation in air or other material easily, but also attaches some dirts easily.The welding of ears of pole plate and bus-bar is bad, be mostly since the oxide layer on ears of pole plate surface and dirt do not clean out cause, therefore the oxide layer and the dirt on ears of pole plate surface must be cleaned out.
During present storage battery is produced, cast welding or manual welding are generally adopted in the welding of bus-bar, oxide layer and dirt on cleaning for bonding ears of pole plate surface, need the cost great amount of manpower and material resources, increased production process, and can produce a large amount of poisonous plumbous particulate dust in the reset procedure, and polluted environment, brought very big harm for producers' health.
Summary of the invention
The object of the present invention is to provide a kind of ears of pole plate method not oxidized in process of production and that do not attached of protecting storage battery by dirt; it uses manpower and material resources sparingly, has improved production efficiency, avoids producing poisonous plumbous particulate dust pollution environment, has protected producers' health.
For achieving the above object; the invention provides a kind of oxidation resistant protection method for ears of pole plate of accumulator; the pole plate production process is to make the grid of metal earlier; be processed into green plate with grid then; green plate is fit into the chemical energy source to be activated that electric energy is provided as storage battery in the storage battery; in 24 hours after grid is produced; after grid is heated to 15～100 ℃; on grid plate ear, smear the last layer protective agent; this protective agent is controlled at 180～80 ℃ in the temperature in smearing; its molten point be higher than this green plate produce in the temperature of each link, its boiling point is lower than this ears of pole plate and bus-bar cast welding or the temperature when freezing mutually.
This protective agent is a microcrystalline wax, and it is raw material with decompression residuum, through propane deasphalting, furfural treatment, benzol-kentone dewaxing de-oiling, clay finishing and make.
This ears of pole plate is metallic lead or plumbous and other metal alloy.
The boiling point of this microcrystalline wax is 340 degrees centigrade, and this ears of pole plate and bus-bar cast welding or the temperature when freezing mutually surpass 450 degrees centigrade, and the temperature of each link all is no more than 70 degrees centigrade in this green plate production.
The present invention has following beneficial effect: the present invention does diaphragm with microcrystalline wax and covers on the ears of pole plate; not oxidized or the dirt pollution of protection ears of pole plate in the green plate production process; in welding process, vapor away convenient welding; the welding quality and the production qualification rate of ears of pole plate and bus-bar have been improved on the one hand; saved the ears of pole plate cleaning technology on the other hand; reduce production cost, reduced environmental pollution, avoided producers' lead poisoning.
