Abstract

The invention relates to a method for testing saline-alkaline corrosion aging performance of a biodegradable film material, which comprises the following steps: mounting an upper clamp and a lower clamp in a constant-temperature and constant-humidity box, fixing the lower clamp, and connecting the upper clamp with an initial counterweight outside the constant-temperature and constant-humidity box through a wire and a guide wheel; clamping a biodegradable membrane material sample on the upper clamp and the lower clamp; hanging a test balance weight on the initial balance weight, and installing a trigger type timer below the test balance weight; automatically spraying a saline-alkaline corrosion solution prepared in advance onto the biodegradable membrane material sample; and turning on the trigger type timer, starting timing, and stopping timing until the test counterweight falls, thereby obtaining the corrosion fracture time of the biodegradable film material sample. The corrosion and aging resistance time of the membrane material can be accurately tested, manual sampling is not needed in the testing process, and testing errors caused by manual sampling are avoided.
