Abstract

The invention discloses a curing and drying process of the unformed plate in a lead-acid battery. The process comprises a curing stage and a drying stage, wherein the temperature at the curing stage is 55-70 DEG C, the curing humidity is 90-98 percent, and the curing time is 0-12 hours, the drying temperature is 55-70 DEG C, the drying humidity is below 30 percent, and the drying time is 24 hours. The curing and drying time of the unformed plate in the lead-acid battery can be shortened, and the energy consumption and the cost can be reduced.

Description

technical field [0001] The invention relates to a curing and drying process for a lead-acid battery raw plate. Background technique [0002] In the production process of acid batteries, the unconverted free lead and moisture content in the lead paste of the lead-acid battery raw plate are too high, it needs to be cured and dried to reduce it to a lower level, the free lead drops below 6%, and the moisture dropped below 1%. The specific process flow is to mix the paste first, then apply the mixed lead paste to form a wet green plate, and then pass the wet green plate through a curing and drying process to form a dry green plate. [0003] At present, there are two curing processes for lead-acid battery raw plates: high temperature curing and room temperature curing. The high temperature curing temperature is 75-90°C and the humidity is 90-98%. . In the drying process, the drying temperature is 60-90°C, and the humidity is below 30%. The above-mentioned curing and drying pr...
