TH75765B - A set of test equipment for corrosion parameters of lacquered steel plates through temperature-controlled molding simulation. - Google Patents

Abstract

DC60 The invention presents a temperature-controlled simulation-based corrosion test apparatus for lacquered steel sheets. The apparatus comprises a base with a glass tube mounted on top and a test specimen mounted on the bottom. The test specimen is formed by molding at a 90-degree angle. The top cover of the corrosion test apparatus (13) has holes for mounting the auxiliary electrode, reference electrode, and thermometer. One end of the current electrode has a wire connected to a potentiostat/galvanostat, which accepts/applies electric potential and reads the test results via a computer. The side walls of the glass tube container are the outer walls of the corrosion test apparatus. The bottom of the corrosion test apparatus has a connection to the inlet pipe, while the top has a connection to the outlet pipe to the eddy current temperature controller. The invention presents a temperature-controlled simulation-based corrosion test apparatus for lacquered steel sheets. The apparatus comprises a base with a glass tube mounted on top and a test specimen mounted on the bottom. The test specimen is formed by molding at a 90-degree angle. From the mold forming at a 90 degree angle, the top cover of the corrosion tester (13) has holes for installing the range terminal, reference terminal and temperature thermometer. At one end of the current terminal, there is a wire connected to the potentiostat/galvanostat which functions to receive/enter electric potential and read the test results by controlling from the computer. And the side area which is the outer wall of the glass tube container. The bottom of the corrosion tester has a way to connect to the water inlet pipe. The top has a way to connect to the water outlet to the eddy current temperature control device.
