In any water electrolysis machine—whether it is a residential alkaline water ionizer or an industrial hydrogen generator—the metal electrode is the core component. The quality of the electrode directly dictates the quality of the treated water and the longevity of the machine.
During the electrolysis process, the environment inside the cell is incredibly harsh. The water generates strong oxidizing substances such as Ozone ($O_3$), Hydrogen Peroxide ($H_2O_2$), and Hypochlorous Acid ($HClO$). Furthermore, many modern systems frequently reverse polarity to clean the plates.
To withstand these conditions, standard metals often fail. This is why Titanium-based coated electrodes have emerged as the industry standard.
Why Titanium? 5 Essential Requirements for Electrodes
For an electrode to function effectively in water treatment and industrial electrolysis, it must meet five strict criteria. Our Titanium electrodes are engineered to exceed these requirements:
Superior Conductivity: To ensure efficient energy transfer.
Strong Corrosion Resistance: To withstand acidic, alkaline, and oxidative environments.
Mechanical Strength: Durable enough to resist processing and high-pressure flows.
Long Service Life: Reducing maintenance costs and downtime.
High Electrocatalytic Performance: Maximizing the reaction rate and efficiency.
The Technology: Platinum Group Coatings
We have developed a specialized Titanium Metal Coated Electrode designed specifically for the water treatment sector. These are “Insoluble Anodes” created by coating a pure Titanium (TA1) substrate with high-performance Platinum group precious metal oxides.
Key Technical Advantages
Resistance to “Wet Chlorine”: In electrolysis, even trace amounts of chloride ions can cause rapid pitting corrosion in stainless steel plates. Titanium is immune to this, ensuring the electrode does not degrade or contaminate the water.
Energy Efficiency: The addition of Platinum group metals significantly lowers the overpotential, meaning higher current efficiency and better conductivity. This translates to energy savings during operation.
Polarity Reversal Capable: Our electrodes are designed to handle the frequent current reversals used in self-cleaning water machines without shedding their coating.
Lightweight & Strong: Titanium has a low specific gravity but high strength, reducing the overall weight of the equipment while maintaining structural integrity.
