Observe that if there is only a small amount of metal powder at the bottom of the water, most of which are still suspended in the water, it is a good Dacromet coating solution; if there is spherical powder or cake-shaped powder precipitated , After removing the water, twist the spherical powder by hand, if there is a smooth feeling, it is inferior dacromet coating solution. In the coating solution, choose zinc powder dacromet coating solution with little precipitation, the performance is better.
2, observation method
Use a general microscope to observe the zinc powder deposited on the bottom of the cup after washing to distinguish the quality of the coating solution. Precipitation will appear soon during the washing method, and this zinc powder is not suitable for Dacromet.
