Because the cathode polarization effect more than a range, will lead to a large number of hydrogen, and separation coating becomes porous, rough, loose, scorched, even the powder, quality just drop.
因为阴极极化作用超过一定范围，会导致氢气的大量析出，从而使镀层变得多孔、粗糙、疏松、烧焦，甚至是粉末状的，质量反而下降。
Combined aluminum production practices, and started with the main production and management of startup latter part, the effective control of the cathode voltage drop was analysed.
