Titanium cathode mesh is a mesh-structured material made from titanium as the base material. It is widely used in fields such as electrochemistry, water treatment, and the electrolysis industry, particularly excelling in the chlor-alkali industry, hydrogen production through water electrolysis, wastewater treatment, and cathodic protection systems. It boasts strong corrosion resistance, excellent conductivity, high mechanical strength, and a long service life, making it one of the indispensable key components in modern industry.
1. Main characteristics and advantages of titanium cathode mesh
Excellent corrosion resistance
Titanium can form a dense oxide film in most acid, alkali, and salt solutions, effectively resisting corrosion from the medium. Especially in oxidizing environments, its stability is excellent, comparable to that of platinum materials.
Good conductivity
Although pure titanium is less conductive than copper or aluminum, its electrochemical activity can be significantly enhanced through surface treatment (such as coating with noble metal oxides), making it suitable for hydrogen evolution or oxygen evolution reaction environments.
Customizable design
It can be processed into different hole patterns (such as diamond, round, hexagonal), thicknesses (0.1–2mm), and widths (5–1600mm) according to actual needs, meeting the installation requirements of various electrolytic cells.
Long lifespan and reusability
The titanium substrate is sturdy and durable. Even if the active coating fails, it can be recoated and regenerated, reducing long-term usage costs.
II. Common application scenarios
Chlor-alkali industry: used as the cathode support grid or current collector grid in ion-exchange membrane electrolyzers, in conjunction with titanium anodes, to ensure uniform current distribution.
Water treatment: As an electrode component in sodium hypochlorite generators and ozone generation devices, it participates in electrochemical reactions to generate strong oxidants.
Cathodic protection system: used for anti-corrosion protection of marine engineering, underground pipelines and other facilities, extending the service life of metal structures.
Electroplating and metallurgy: Serving as an auxiliary electrode or conductive substrate, it plays a stabilizing role in the electrodeposition process.
