Method for cleaning surface oil dirt of lead alloy grid produced through continuous casting

Abstract

The invention discloses a method for cleaning surface oil dirt of a lead alloy grid produced through continuous casting. The method comprises the following steps of S1 blowing air to remove dust, S2 preparing a solution according to the proportion, S3 soaking a matrix, S4 preparing deionized water, S5 conducting washing to remove dirt, S6 taking out the lead alloy grid and wiping the lead alloy grid, S7 adjusting the drying temperature, and step S8 conducting drying. According to the method for cleaning the surface oil dirt of the lead alloy grid produced through continuous casting, an alkaline solution and the oil dirt conduct saponification to achieve the effect of removing the oil dirt; the OP-10 emulsifier has excellent level dyeing, emulsification, wetting and diffusion capacities, the OP-10 emulsifier can easily form an interface layer on the interface of water and oil to well disperse one party into the other party, so that two liquids which are insoluble to each other can form a stable emulsion, and the OP-10 emulsifier is an alkaline, efficient and low-foam emulsifier with strong oil-removing and dirt-removing capabilities, and is easy to clean, environment-friendly and healthful; and sodium dodecanesulphonate has good emulsifying, foaming, permeating and dirt-removing effects, and has no harm to human bodies, so that the problem that oil-removing products harm the human bodies is solved.

Description

technical field [0001] The invention belongs to the field of lead-acid storage batteries, and in particular relates to a method for cleaning oil stains on the surface of lead alloy grids used in continuous casting production. Background technique [0002] The continuous casting process is adopted in the production of the lead-acid battery grid, which has the advantages of high production efficiency and less lead recycling. However, during the production process, the release oil will be sprayed on the continuous casting mold, and the release oil will adhere to the grid. , These oils must be removed before coating the board, otherwise it will reduce the bonding force between the grid and the lead paste, and at the same time increase the internal resistance of the battery, which will have a great adverse effect on the battery life and starting ability. [0003] Common degreasing methods include organic degreasing, inorganic degreasing, ultrasonic degreasing, etc. [0004] Orga...

Problems solved by technology

[0004] Organic degreasing products include toluene, xylene, trichlorethylene, etc. Although they can directly dissolve oil, they usually have a pungent odor, endanger human health, and pollute the environment. Most of the inorganic degreasing products contain strong alkalis such as sodium hydroxide to lead It has a strong corrosive effect, and usually needs to be heated to a higher temperature to have a better effect. At this time, the volatile alkali mist will seriously damage people's health and pollute the environment. Due to the high noise of ultrasonic degreasing, it is harmful to employees great impact on health
