Cathodic Protection Sacrificial Water Heater Magnesium Anode Extruded Az63B 1.7V
Extruded Magnesium Rod In Hot Water Tank Cathodic Protection Magnesium Sacrificial Anode Az63B 1.7V
Introduction:
Magnesium rod is the common name of magnesium anode, also known as anode magnesium rod, which is used to prevent the corrosion of metal liner and soften the water quality of water heater. That is, the magnesium rod is used as the anode, the metal lining is the cathode, and the water in the liner is the dielectric to form a primary battery.
Specification:
| Product Type: | Magnesium rod |
| Material: | Magnesium alloy AZ31 |
| Differnet kinds: | Casting rod,Extruded rod,Rod with steel cap,Flexible anode rod |
| Chemical composition: | Al:2.5-3.5%, Zn:0.6-1.4%,Mn:0.2-1.0%,Fe:0.005%max,, Cu:0.01%max,Ni:0.001%max,Si:0.1%max, Other:0.3%max,Mg:Balance |
| Propertices: | Open-circuit voltage: 1.5-1.55V Close-circuit voltage:1.45-1.50V Actual capacitance: 1.105A.h/g Current efficiency:50%min |
| Steel cap: | stainless steel,galvannized ,in black,coppper,etc. |
| Application: |
It mainly used in water heater,boiler,heat exchanger,water tank,etc. It can soften water,de-dirt residual,ensure water sanitation,water scale inhibition,protect inner tank,extend service life,etc. |
| Features: |
The extruded anode rod can be with or without steel core,can be with steel cap or only with screw;the size of cap/screw can be customilized by your specific requirements. Mainly different kinds of steel cap and screw available. |
Features:
- The potential is relatively negative, the polarizability is low, the density is small, the theoretical capacitance is large, the effective potential difference with iron is large, and the protection radius is large.
- Through secondary refining, high purity, less impurities and dense structure
- Small grains, high current efficiency and good electrical properties
- The content of flux slag is low
- The surface is smooth, clean, free of pores, shrinkage cavities and slag inclusions
- Products of different specifications can be designed and produced according to user requirements to meet customer needs
Regular replacement:
Once the magnesium rod is consumed, if it is not replaced in time, it is easy to cause corrosion of the inner tank or corrosion and perforation of the heating tube, which will lead to the danger of electric leakage and cause personal injury accidents. Therefore, the storage-type electric water heater needs to clean the inner tank and replace the magnesium rod regularly.
