Two-day curing process for positive plate of storage battery

Abstract

The invention aims to provide a two-day curing process for a positive plate of a storage battery. The two-day curing process comprises eleven steps, wherein curing is carried out from step 1 to step 5, the curing temperature, time and humidity of each step are adjusted to be optimal, drying is carried out from step 6 to step 11, the drying temperature and time of each step are also adjusted to be optimal, and the total time does not exceed two days. By the two-day curing process, the time is shortened, the curing quality is ensured, and the energy efficiency and the production efficiency are improved.

Description

Technical field [0001] The invention relates to the field of production and manufacture of battery grids, in particular to a two-day curing process for battery positive plates. Background technique [0002] The solidification of the electrode plate means that the electrode plate coated with the paste will complete the oxidation of the free lead and the lead on the grid rib surface and the recrystallization and recrystallization of the basic lead sulfate during the gelation process of the lead paste under certain temperature and time conditions. The hardening process. In the solidification and drying process of the electrode plate, as the mass transfer process of the evaporated water progresses, it is not allowed to destroy the network structure; at the same time, the oxidation of the metal lead and the 3PbO·PbSO4·H2O must be completed before the water is evaporated Crystallization process. Therefore, when choosing a curing process, the three parameters of curing temperature, re...

Problems solved by technology

Several functions in the curing process are interrelated. No matter which function is not achieved, the curing effect will not be very good, which will affect the capacity and life of the battery.

However, at present, the curing time of the battery positive plate is very long, and it takes more than three days or more to achieve the curing effect. There is also a two-day curing process in production, but the current two-day curing process is poor, and there is an urgent need for a new one in production. Therefore, how to control the curing temperature, relative humidity and curing time of the plate to achieve the curing effect of the positive plate is very important.
