Method for detecting low-temperature brittleness of zinc anode ribbon

The invention relates to a method for detecting low-temperature brittleness of a zinc anode ribbon, which comprises the following steps: (1) determining a plurality of test temperature points, and preparing the corresponding specification and number of samples; (2) cooling the samples for heat preservation for 4 to 5 hours; (3) measuring the maximum bending diameter of the samples at a certain test temperature point; and (4) changing the temperature of a cooling medium to the other test temperature point within the test temperature range, measuring the maximum bending diameter of the samples at the temperature, and establishing a temperature (T)-maximum bending diameter (phi) database according to the maximum bending diameter under each test temperature point. The method is simple, easy to operate, and simple and direct and quick to measure; and the ductile-brittle transition temperature range of the zinc anode ribbon is judged quantificationally according to the database, and the method ...
