铅酸蓄电池板极固化过程中板栅表面腐蚀变化过程

The curing process of lead-acid battery grid surface corrosion changes in curing process of grid surface corrosion changes. Especially in the grid surface in contact with the active material interface through curing to form a layer of corrosion film, curing process at high temperature and high humidity for 24 72h cycle. In this case, oxidation of the metal will accelerate the corrosion process, in the grid is formed on the surface of lead oxide layer, the oxide layer and cured paste skeleton provides direct contact. On the positive, in the form of first is corrosion layer is oxidized to PbOn ( n>l ) and PbO2 then is cured paste oxidation. Similarly for negative electrode, corrosion layer is first reduction, and then curing the paste.

Plate gate in the oxidation processes of lead or curing process grid corrosion layer formed on the surface is a very important process, but also the active substances can and grid with tightly hold the essence reasons and the main reasons. Grid surface after oxidation of lead oxide is deposited in the grid surface, growing into the paste. The paste and grid surface is created between a very strong connection, ensure thereafter active substance is closely attached to the grid, not shedding of active material. Drape paste plate gate in the curing process can occur in a loss, in the grid / paste on the inside surface of solidified effect process. With 4cmZ plate ( plate grid alloy is Pb-1.6%Sb0.1%As ) double side paste coating.

High temperature curing corrosion layer thickness, have very strong corrosion layer / cathode active material of good contact. Thus forming a layer of appropriate properties of corrosion layer is the important objective of plate curing, high temperature curing can contribute to this purpose.
