Embodiment
[0014] A paste extrusion type production of tubular positive plates and a paste and curing process, this process is applicable to the extrusion paste production of all tubular positive plates, characterized in that:
[0015] 5) Additives: graphite 0.2-0.5%, 0.8-1.2mm long and short fibers 0.6-0.8%, silica sol 1-5%, calcium sulfate 0.25-0.5%, nano-scale tetrabasic lead sulfate 0.2-0.4%.
[0016] 6) Lead powder adopts an oxidation degree of 72-80% and an apparent specific gravity of 1.2-1.3g / cm 3 Lead powder, sulfuric acid adopts dilute sulfuric acid solution with a content of 20-25%,
[0017] 7) Premixing of ingredients: Premixing graphite, long and short fibers, calcium sulfate, and nano-scale tetrabasic lead sulfate with 3-5% lead powder for 30 minutes;
[0018] 8) Preparation method: first add the pre-mixed additives into the paste machine, and then add the remaining amount of lead powder. During the process of adding lead powder, add lead powder, add water, and stir. The a...
