Embodiment 1
[0037] Adopt detection method of the present invention to detect Z80 galvanized sheet zinc weight specific steps are as follows:
[0038] (1) Prepare zinc-dissolving chemical reagents: add 100mL deionized water to the beaker, then add 120.0g potassium hydroxide, 8.7g disodium edetate, mix the solution thoroughly and heat to 80°C to stir evenly, then add 0.45g of triethanolamine, mixed and stirred for 3 minutes until uniform to obtain the zinc-dissolving chemical reagent, and then set aside;
[0039] (2) Galvanized sheet sample preparation: Wipe both sides of the galvanized sheet sample with 60mm diameter Z80 galvanized sheet disc with alcohol, blow it dry with a blower, and weigh it as M 1 , accurate to 0.1mg;
[0040] (3) Galvanized sheet sample zinc dissolution: put the weighed 60mm diameter Z80 galvanized sheet disc into the prepared zinc-dissolving chemical reagent, the liquid surface of the zinc-dissolving chemical reagent should not cover the galvanized sheet sample, S...
