Description
Technical Field
The invention relates to the field of storage battery lead plaster, in particular to a low-temperature lead plaster mixing process of negative plate lead plaster.
Background
The storage battery is often used in life, wherein the storage battery comprises a lead-acid storage battery, and the lead-acid storage battery comprises a grid. The surface of the grid needs to be coated with lead plaster in the production and manufacturing process. The lead plaster is obtained by stirring lead powder, auxiliary materials and sulfuric acid, and the lead plaster is prepared by adopting a plaster mixer to mix. At present, lead powder and sulfuric acid react to release a large amount of heat, and due to the fact that the reaction is too violent, the temperature of the paste mixing cannot be effectively controlled in the existing process, and the lead paste of the negative plate and the height of the paste process temperature have large influence on the low-temperature performance of the battery. Therefore, it is necessary to solve this problem.
