Abstract

The field of lead battery manufacturing of the present invention specifically relates to a process of internally forming battery pole plate winter paste, which specifically includes the following steps: adding corresponding materials to the lead powder metering bucket, sulfuric acid metering barrel, and water metering barrel respectively according to the formula metering; Add the auxiliary materials measured by the formula into the paste pot, then add the measured lead powder into the paste pot during the continuous stirring process, and continue to dry mix for 8-10 minutes after the lead powder is added; Add water, and the duration of the adding process is 1-2min. After adding water, stir for 5-7 minutes, and add all the water according to the amount of water used. When the ambient temperature is ≤20°C, pre-heat the water temperature to 30- 50°C; Add the measured sulfuric acid evenly into the paste pot during the continuous stirring process, and the adding process lasts for 13-15 minutes. When the ambient temperature is ≤20°C, pre-heat the temperature of the sulfuric acid to 20-40°C; At the same time, control the temperature in the mixing paste pot to ≤60°C; stir for 10-25 minutes after adding the acid, and take out the pot after testing the apparent density of the lead paste to meet the standard.

Description

technical field [0001] The invention relates to the field of lead battery manufacturing, and specifically relates to a process of internalizing battery pole plates and mixing paste in winter. Background technique [0002] Lead paste is the matrix of the active material of the pole plate. It is a paste-like substance with certain plasticity formed by mechanical stirring and mixing of lead powder with a certain degree of oxidation and apparent density, water and sulfuric acid solution. The role of lead paste in lead-acid batteries is mainly to provide and store the substances required for electrochemical reactions. Lead paste is a plastic substance mixed with lead powder, water, sulfuric acid and additives. Its properties are mainly manifested in the apparent density and consistency of lead paste. Therefore, the prepared lead paste should have good plasticity, so that the lead paste can be easily bonded to the grid when coating the board, and can be evenly coated and filled w...
