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 plate is very long, more than three days or more, and a process with a short curing time is urgently needed in production. Therefore, how to control the plate curing temperature, relative humidity and curing time to improve The problem of plate curing consistency is particularly important

Abstract

The invention provides a two-day curing process of an accumulator plate. The process comprises a positive plate curing process and a negative plate curing process. A positive plate and a negative plate are cured firstly and then dried; temperature, humidity and time in each stage can be controlled accurately, the time of the whole process is shortened to be not more than two days, the quality of the cured positive plate and negative plate meets requirements, the production efficiency is improved greatly, and the process is suitable for production.

Description

technical field [0001] The invention relates to the field of storage battery production, in particular to a two-day curing process for storage battery pole plates. Background technique [0002] The curing of the pole plate refers to the completion of the oxidation of free lead and lead on the surface of the grid ribs and the recrystallization of basic lead sulfate and hardening process. During the solidification and drying process of the plate, as the mass transfer process of evaporated water proceeds, its network structure is not allowed to be damaged; at the same time, before the water evaporates, the oxidation of metal lead and the oxidation of 3PbO?PbSO4?H2O must also be completed. crystallization process. Therefore, when selecting a curing process, the three parameters of curing temperature, relative humidity and curing time should be strictly controlled. Several functions in the curing process are interrelated. No matter which function is not achieved, the curing ef...
