No other components enter the process from the raw material (zinc ingot) to the zinc anode, and no contact with other metals. Using DF-100 direct reading spectrometer, plasma inductively coupled atomic emission spectroscopy and other high-end detection instruments. From raw materials - processing - warehousing each process layer control, layer detection. Do not let go of any small details, so that our product performance is long-term stable. Ensure that the zinc anode content of each batch is above 99.995%.
