The main functions of passivation
Improvement of corrosion resistance: The core purpose of passivation is to significantly reduce the rate of corrosion of metals by forming a thin and stable oxide or passivation film on the metal surface, which effectively isolates the metal from direct contact with corrosive substances in the external environment (such as moisture, oxygen and chemicals).

Types and Differences of Plating Freezers
Indirect freezing type electroplating freezer conveys water to the condenser of the chiller through the water pump to cool down, and then cools down the sulphuric acid in the electroplating tank through the heat exchanger. The advantage of this cooling method is that it is easy to install, has a longer service life, and the acid and alkali are not easy to corrode the chiller. The disadvantage is t
