D. treat described thin slice cooling forming, the size by accurate requirement cuts again, becomes required separators.
In the practice, the operating sequence of above-mentioned steps A and step B can be changed, and the material of described plastic tab is ABS, PP or PE.
The present invention solve the technical problem and can also further realize by coming by the following technical solutions:
Design, make a kind of baffle plate of lead acid storage battery, be that a kind of basis material thickness is (0.4～1.2) mm, and evenly dig the plastic tab that several rows of aperture is arranged, the lines that compacting is arranged on this plastic tab, the cross section undulate of thin slice and integral thickness are (1.4～2.5) mm, and the material of described plastic tab is ABS, PP or PE thin slice.
Compare with prior art, the technique effect of baffle plate of lead acid storage battery of the present invention is:
1. because material matrix thin thickness such as ABS, PP, PE, between 0.4～1.2mm, but also on matrix, beaten a lot of holes, so use the present invention's dividing plate, in the identical inside battery useful space, can be than the electrolyte of the conventional dividing plate storage of Duoing 10～18%;
2. owing on the matrix of materials such as ABS, PP, PE, beaten a lot of holes, battery is in charge and discharge process, and electrolyte can be more unimpeded passes through intensive aperture, and the resistance that is subjected to of the electromigration of effects of ion is little like this, cause the internal resistance of battery little, its internal resistance is than conventional PVC, PVC-SiO
2, dividing plate internal resistance such as rubber is little by 5%～10%;
3. production cost is low.
