Lead-acid storage battery positive plate circular water cleaning process

Abstract

The invention discloses a lead-acid storage battery positive plate circular water cleaning process. The lead-acid storage battery positive plate circular water cleaning process is characterized by comprising the following steps that after a negative plate is charged, grooving is carried out, after grooving, the plate is cleaned in 1-2# washing ponds, in the 1-2# washing ponds, circular tap water is used, the washing time ranges from 5 min to 10 min, in a 3# washing pond, pure water is used for carrying out immersing for three to five minutes, calcium carboxymethylcellulose is added in the purewater, the mass percent ranges from 2 to 6%, and after the calcium carboxymethylcellulose is completely dissolved in pure water, an air pipe is used for carrying out aeration for one to three minutes. The water washing method is simple, operation is easy, the floating powder on the surface of the negative plate obtained after water washing is reduced by about 47%, and the difficulty and the treatment cost of environment-friendly treatment of brush plates can be reduced.

Description

technical field [0001] The invention relates to a production process of a battery pole plate, in particular to a process for cleaning the positive plate of a lead-acid battery with circulating water. Background technique [0002] The development trend of batteries is moving towards the direction of energy saving and consumption reduction. The successive promulgation of national laws and regulations shows that the country attaches great importance to environmental protection. [0003] The traditional lead-acid battery production process is extensive, and the treatment of lead fume and lead dust is not in place. Up to now, there are still many small battery factories that do not deal with lead fume and lead dust. In the whole manufacturing process, the source of such pollution is the brush plate. Because there is floating powder on the surface of the negative plate, a large amount of lead dust will be raised when the plate is divided. Although large enterprises have good envir...

Problems solved by technology

[0003] The traditional lead-acid battery production process is extensive, and the treatment of lead fume and lead dust is not in place. Up to now, there are still many small battery factories that do not deal with lead fume and lead dust. In the whole manufacturing process, the source of such pollution is the brush plate. Due to the floating powder on the surface of the negative plate, a large amount of lead dust will be raised when the plate is divided. Although large enterprises have good environmental protection equipment , but as long as it is not a closed operation, it is impossible to treat these pollutions perfectly, so if you want to reduce environmental protection costs and reduce pollution sources, you must reduce the floating powder on the surface of the negative plate before brushing the plates
