Abstract

The invention discloses a paste mixing and curing technology for paste-squeezing production of a tubular positive plate. The technology is applicable to paste-squeezing production of all tube positive plates. The paste mixing and curing technology is characterized by comprising the following steps: with an additive, lead powder of which the oxidizability is 72%-80% and the apparent specific gravity is 1.2g / cm<3> to 1.3g / cm<3>, and a dilute sulfuric acid solution with the sulfuric acid content of 20%-25% as ingredients, premixing the ingredients; and stirring graphite, long and short fibers, calcium sulfate, nanoscale tetrabasic lead sulfate and 3%-5% of lead powder at a formula ratio for 30 minutes, and premixing, mixing and curing the mixture. The paste mixing and curing technology has the advantages that the problem of cracking of lead plaster in a production process is avoided; the lifetime of a storage battery is prolonged; a reliable guarantee is provided; compared with other technologies, the technonoly makes the capacity improved by over 15%; the lifetime is prolonged by 20%; dust in the conventional paste mixing technology is completely eradicated; and the paste mixing and curing technology is a novel environment-friendly production technology.

Description

technical field [0001] The invention belongs to the technical field of accumulators, and in particular relates to a paste-extruding type production of tubular positive plates and paste and a curing process. Background technique [0002] At present, the lead paste on the positive plate in the existing battery production is easy to crack, the scrap rate is high, and the life of the battery is low; in the past, the paste process has a lot of dust, serious environmental pollution, and the disadvantages of the working environment and labor intensity of the workers. . Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a kind of extruding paste type production tube type positive plate and paste with simple process, high production efficiency, long service life, high yield and no pollution to the production environment. curing process. [0004] In order to realize the above-mentioned purpose of th...
