magnesium anode
(1)Corrosion protection magnesium anode
(2)protect water heater, water containers of steel structure magnesium anode
(3)protect the gas pipeline in-home service polarization high resistance electrolytes (soil and water in the steel structure)
Usage:
Anode is mainly used in equipment such as water heaters, heat
exchangers, evaporators, and boilers, etc. It can soften water,
remove dirt, and prolong the life of the main machine. Magnesium
alloy water heater sacrificial anode can be divided into casting type
and extruded type is widely used for the anti-corrosion of water
heater and boiler.
