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 specifically is a process for producing tubular positive plates and pastes in paste extrusion and curing. Background technique [0002] At present, the lead paste on the positive plate in the current battery production is easy to crack, the rejection rate is high, and the battery life is relatively low; the dust in the past and the paste process is very large, the environmental pollution is serious, and the working environment and labor intensity of the workers are high. . Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, and provide a paste extrusion type production tubular positive plate and paste with simple process, high production efficiency, long service life, high yield, and pollution-free production environment. Curing process. [0004] In order to achieve the above-mentioned purpose of the invention, the present in...
