How to clean the battery aluminum shell?

First, manual cleaning, eradication of oil scale

Usually, we know that when the oil is particularly heavy or meets high soluble point lipids, part of the oil scale on the aluminum shell of the battery should be removed manually or mechanically.

Two, the use of professional cleaning liquid cleaning

1) Configuration of cleaning liquid

A. Preparation of cleaning solution: according to the degree of oil pollution, it can be mixed with water up to 30 times.

When used, according to the severity of oil pollution to adjust the concentration of cleaning liquid, in order to get the cleaning effect of the battery aluminum shell, is generally prepared with the original liquid and water concentration of 3% ~ 10% cleaning liquid, heating to 30 ~ 50℃ spray cleaning or ultrasonic cleaning for 3 ~ 10 minutes, manual cleaning cleaning agent concentration is relatively high.

B. Cleaning temperature: can be cleaned at room temperature, high temperature, good cleaning effect.

C. Cleaning method: Soak the battery aluminum shell to be cleaned in cleaning solution, scrub, scrub and soak respectively according to the situation, and also use mechanical spray cleaning and ultrasonic cleaning with pressure of more than 0.5Kg/cm2.

According to the amount of oil stain on the aluminum shell of the battery to be cleaned, the raw liquid of the product and clean water (tap water or well water) are combined into a cleaning solution of 2%-6%. Immerse the aluminum shell of the battery to be washed in the prepared cleaning solution and soak for 3-5 minutes. Remove the impregnated battery aluminum case from the cleaning solution and thoroughly clean the battery aluminum case with clean water. The cleaning solution can be used repeatedly. Due to the gradual reduction of effective components in the process of repeated use, an appropriate amount of aluminum degreaser raw solution should be added in time, and the added amount is 0.1-0.3% of the total cleaning solution.

If there is dirt on the surface of the battery aluminum shell, it also has an impact on the battery, so we must clean the dirt on the surface of the battery aluminum shell. In the process of using the battery aluminum shell, in addition to understanding the method of cleaning the aluminum shell, we also need to understand the factors that affect the quality of the power battery aluminum shell, we have talked about in front, we can combine to understand. This is helpful for us to understand the aluminum shell of the battery.
