Abstract

The invention provides a device for testing the electrochemical corrosion resistance of pole sealant and a method for testing the electrochemical corrosion resistance of the pole sealant by the aid ofthe device. The device comprises a battery jar and positive and negative terminals. The battery jar comprises a shell and a cover, pole holes are formed in the cover, the positive and negative terminals include a positive lead terminal and a negative lead terminal, and sealant poles are arranged in the middle of the positive lead terminal and the middle of the negative lead terminal and are fixedinto the pole holes. The device and the method have the advantages that practical working principles of batteries are simulated by the aid of the method, a novel evaluation process is established, the corrosion resistance of the sealant and sealing binding force of the sealant and lead poles can be visually reflected by the corroded lengths of the lead poles in the sealant poles, accordingly, thedevice and the method conform to practical working conditions of the storage batteries and are suitable for selecting and evaluating the sealant, and accurate results can be obtained by the aid of the device and the method.

Description

technical field [0001] The invention relates to a test method and a test device for the electrochemical corrosion resistance strength of pole sealant. Background technique [0002] Lead-carbon energy storage batteries are widely used in the field of energy storage due to their excellent charge acceptance, and their service life reaches 10-15 years. This requires that the sealing effect of the battery can reach more than ten years. If glue is used for chemical sealing when sealing the pole, the stronger the electrochemical corrosion resistance of the sealant, the better. [0003] However, the existing technology does not have a good test method for the electrochemical corrosion resistance of the sealant. The existing standard and method for detecting corrosion resistance is: the sealant is made into a sample block, and the mass M 1 , soak it in dilute sulfuric acid with a density of 1.3g / ml for 120 hours, then weigh the weight M 2 , the difference between the two is the pic...
