Washing method for reducing floating powder on surface of positive plate

Abstract

The invention discloses a washing method for reducing floating powder on the surface of a positive plate. The method is characterized by comprising the following steps of after forming and charging the positive plate, grooving the positive plate; washing the positive plate in a 1# washing tank and a 2# washing tank after finishing grooving the positive plate, wherein circulating tap water is used in the 1# washing tank and the 2# washing tank, and the washing time is 5 to 10 minutes; and soaking the positive plate for 3 to 5 minutes with purified water in a 3# washing tank, wherein 2 to 6 mass percent of carboxymethyl cellulose is added into the purified water, and after the carboxymethyl cellulose is completely dissolved in the purified water, aerating the plate for 1 to 3 minutes by using an air tube. The washing method is simple and easy to operate, the floating powder on the surface of the positive plate is reduced by about 47 percent, and the difficulty and treatment cost of environment-friendly treatment on a brushing plate are reduced.

Description

technical field [0001] The invention relates to a production process of battery pole plates, in particular to a water washing method for reducing floating powder on the surface of positive pole plates. 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 positive plate, a large amount of lead dust will be raised when the plate is divided. Although large enterprises have good env...

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. Because there is floating powder on the surface of the positive 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. Therefore, if you want to reduce environmental protection costs and reduce pollution sources, you must reduce the floating powder on the surface of the positive plate before separating the plates
