Abstract

PURPOSE: In measurement of deposited zinc amount of galvanized steel plate, a sample is reacted with a specific testing solution to generate hydrogen, and its pressure is measured, thereby reducing the time and work of conventional methods and providing simple measurement means of deposited zinc amount.
CONSTITUTION: A sample (20 × 50 mm) of galvanized steel plate is inserted into the closed container 1 (closed by the cover press 3) having the cover mated by ground surface, which is connected to the mercury pressure gage 5. Sb2O3 32g dissolved into 1 l of hydrochloric acid is put in the container 4, which is rotatably connected to the closed container 1 through ground surface. The container 4 is rotated to feed the solution until the sample is immersed enough into the liquid, and the evolved hydrogen is measured by the gage 5 in pressure increase. The calibration is preliminarily made in relation of zinc deposition (g/m2) and hydrogen pressure increase (mmHg), which facilitates the measurement of zinc deposition by pressure increase.
