Problems solved by technology

At present, the alkali resistance of the conductive coating is mainly determined by the resin in it, but there is no method to evaluate the alkali resistance of the resin in the electrolyte, which has a great influence on the evaluation and selection of the resin used, so it is necessary to establish a suitable alkali Targeted test methods needed for manganese batteries

Embodiment 1-5

[0025] Examples 1-5: Test 5 different conductive resins were tested.

[0026] Test method for alkali-resistant alkali-resistant resin with an alkali manganese battery, and the specific operation steps are as follows:

[0027] (1) Preparation of a steel sheet having the same material as the alkali manganese battery, coated with a resin on a steel sheet and heat it.

[0028] (2) The steel sheet processed after step (1) is placed in container A with an alkali manganese battery electrolyte, sealed and placed in a water bath heating tank;

[0029] (3) After 1 day of 70 ° C, the take-out the steel sheet is placed in container B with water, and the steel sheet is removed after 50S, and the degree of damage to the resin coating is observed to evaluate the alkali resistance;

[0030] (4) The resin coating is pulverized or dissolved in step (3), and 0 points; if the resin coating is not pulverized or dissolved, then rinse the steel plate coating with flow water, and then observe the damage ...

Embodiment 5-10

[0034] The five resins of Examples 1-5 were placed in 7 days in the heating vessel for the alkali resistance (other test methods and conditions as in Examples 1-5), and the test results are shown in Table 2, Table 2 and Table 1. It can be seen that the alkali resistance of the resin will be reduced over time, depending on the resin, select the appropriate test time, and determine the alkali resistance of the resin according to the test time. From Examples 1-10, it can be obtained, and the resin-resistant alkali resistance is from good to the difference of No. 5 resin, No. 4 resin, No. 3 resin, 2 resin, 1 resin.

Abstract

A method for testing the alkali resistance of resin for an alkaline manganese battery conductive agent comprises the following specific operation steps: (1) preparing a steel plate made of the same material as an alkaline manganese battery steel shell, coating the steel plate with resin, and heating and curing the resin; (2) putting the steel plate treated in the step (1) into a container A filled with an alkaline manganese battery electrolyte, performing sealing, and putting the steel plate into the heating equipment; and (3) after standing at a set temperature for a certain time, taking out the steel plate, putting the steel plate into a container B filled with water, taking out the steel plate after 30-90s, observing the damage degree of the resin coating, and evaluating the alkali resistance of the resin coating. (4) if the resin coating in the step (3) is crushed or dissolved, marking the resin with 0 score; if the resin coating is not crushed or dissolved, washing the steel plate coating with flowing water, observing the damage degree of the resin coating again after washing, evaluating the alkali resistance of the resin coating is evaluated, if the resin layer is crushed, marking the resin with 2 scores, if the resin layer is not crushed after washing, marking the resin with 5 scores, wherein the higher the score is, the better the alkali resistance of the resin is.

Description

Technical field [0001] The present invention relates to the preparation of alkali manganese batteries, especially a test method for alkali-resisting alkali-resistant alkali-manganese cells. Background technique [0002] The alkali manganese battery is an negative electrode of zinc, manganese dioxide is a positive electrode, sodium hydroxide or potassium hydroxide as an electrolyte, and takes a battery made of an anti-polar structure. The steel shell in the alkali manganese battery is both a container of a battery, and a positive electrode fluid, as a positive electrode current, and the uniformity of the inner surface properties affect the current collective effect. In the current steel shell production process, the surface of the steel shell is nickel, but the surface of the steel shell is still chemically corroded, regardless of the elimination or even the needle, the bottom or even there is a leakage, which is usually produced. Coating electrical electrical agent coating in the...
