A kind of rapid solidification and drying process of negative raw electrode plate

Abstract

The invention belongs to the field of lead-acid batteries, and in particular relates to a process for rapid curing and drying of negative raw plates, which at least includes the following steps: (1) curing constant temperature and high humidity maintenance stage → (2) curing temperature rising and dehumidification stage → (3 ) Curing temperature rise and rapid dehumidification stage → (4) Drying temperature rise and rapid dehumidification stage → (5) Drying and high temperature rapid enhancement stage → (6) Drying and cooling rapid and stable stage. According to the green plate solidified and dried according to the procedure of the present invention, the basic lead carbonate content of the green plate increases, the drop strength of the green plate is further improved, the crispness of the lead paste is reduced after falling, and the amount of floating powder on the surface of the green plate is reduced; The improvement of the plate strength reduces the defect rate of the subsequent slicing and wrapping of the raw plate. Less floating powder reduces lead powder dust in the subsequent production process of the plate and reduces environmental pollution; the rapid curing and drying procedure can reduce the consumption of steam and electricity in the process, reduce the energy consumption of curing and drying, and reduce manufacturing costs.

Description

technical field [0001] The invention belongs to the field of lead-acid storage batteries, and in particular relates to a process for rapid curing and drying of negative raw plates. Background technique [0002] Lead-acid batteries are widely used because of their stable performance and high cost performance. Especially, the market demand for electric bicycle batteries is increasing, but the price is getting lower and lower, which puts pressure on the production cost of manufacturers. The manufacture of negative raw plates is indispensable in the battery manufacturing process. Curing and drying in the manufacturing process of negative raw plates is one of the important links in the process. The quality of the curing and drying directly affects the strength of the green plates and the strength of the battery. performance. During the curing and drying process, the raw plate is cured and dried in the curing room, which is in a closed state, and the appearance change of the gree...

Problems solved by technology

Although the current curing and drying process in the curing and drying room can meet the production needs, it has a long cycle, low efficiency in the use of the curing room, and high production costs. Therefore, it is necessary to develop a rapid curing and drying process for the negative plate to reduce process production cost
