Abstract

The invention relates to the lead battery manufacturing field, in particular to a winter paste mixing process for a container formation battery plate. The process specifically includes the steps of: adding corresponding materials into a lead powder measuring hopper, a sulfuric acid measuring barrel and a water measuring barrel respectively according to the formula measurement; adding auxiliary materials into a paste mixing pot according to the formula measurement, then adding well measured lead powder into the paste mixing pot during continuous stirring, then further conducting dry stirring for 8-10min; adding water into the paste mixing pot in the continuous stirring process, and keeping the adding process duration at 1-2min, then conducting stirring for another 5-7min, adding all the water according to a use amount, and when the environment temperature is lower than or equal to 20DEG C, pre-heating the water to 30-50DEG C; adding well measured acid into the paste mixing pot in the continuous stirring process, and keeping the adding process last for 13-15min, and when the environmental temperature is lower than or equal to 20DEG C, pre-heating sulfuric acid to 20-40DEG C; at the same time controlling the temperature in the paste mixing pot lower than or equal to 60DEG C; at the end of acid adding, further conducting stirring for 10-25min, testing the diachylon apparent density, and discharging the diachylon from the pot when the apparent density reaches 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...
