MMO Ru-Ir oxide coated Titanium Mesh Anodes

Introduction:

Titanium mesh plate anode (MMO) is made of precious metal iridium salt coated on titanium mesh plate and sintered at high temperature. Titanium mesh anodes is widely used in electroplating ( copper electroplating and gold electroplating in the circuit board industry), electrolysis and other hydrometallurgical activities. The preparation and application of electrodes are quite mature.

These mmo mesh consist of titanium substrate coated with a thin layer of mixed metal oxide, typically composed of iridium, ruthenium, and titanium oxides.

The MMO coating on the titanium mesh plate anode provides several advantages over traditional anode materials such as graphite or lead. First, the mixed metal oxide coating is highly conductive and has excellent catalytic properties, allowing for more efficient electrochemical reactions. Additionally, the mmo anode is very durable and corrosion-resistant, resulting in longer-lasting anodes that require less frequent replacement.

The design of titanium mesh anodes also offers several benefits. The mesh allows for a larger surface area, which enhances the anode's ability to facilitate electrochemical reactions. The mesh also provides increased mechanical strength, allowing the anode to withstand harsh environments and mechanical stresses.

Specification:

1. Substrate material: GR1, GR2, TA1, TA2 Titanium content ≥99.6%, raw material thickness: 0.1mm-2mm, the titanium mesh produced by mechanical processing, the hole shape is a diamond or round hole, the opening rate is large, the surface area is large, and the strength is high Because of the acid and alkali resistance and conductivity of the titanium mesh itself, it is often used to make battery current collector mesh, oxygen cathode ion membrane electrolyzer titanium anode, filter titanium mesh, electroplating anode mesh and so on.
2. Hole type: diamond and round
3. Thickness: 0.1mm-2mm
4. Width: 5mm-1250mm
5. Diamond hole specifications: 1*2mm, 3*6mm, 3.5*6mm, 5*10mm, 5*12mm, etc. round hole size can be done as your need.

6. Surface: can provide coating treatment processes such as coated ruthenium oxide, ruthenium and yttrium, platinum.
Anode shape: It can be cut into circular diameter 30mm-1200mm, rectangle, square, rhombus and other specifications, or it can be welded by reel to make titanium anodes of other shapes.

7. The titanium mesh electrode has a great advantage over the titanium plate anode. It greatly increases the contact area between the anode and the solution, increases the production capacity, and greatly improves the efficiency, its disadvantage is that the deposit is not as easy to clean as the titanium plate.Application Case

Ru-Ir oxide coated titanium mesh anodes are commonly used in a variety of electrochemical processes, including water treatment, metal electroplating, and electrolytic recovery of precious metals. These mmo anode have several advantages over traditional graphite or lead anodes, including higher efficiency, longer lifespan, and resistance to corrosion.

One specific application of Ru-Ir oxide coated titanium mesh anodes is in the electrochemical production of chlorine and sodium hydroxide (NaOH) using a process called electrolysis. This process involves passing an electric current through a saltwater solution (brine) between two electrodes, one of which is the Ru-Ir oxide coated titanium mesh anode.

During electrolysis, chloride ions in the brine are oxidized at the anode to produce chlorine gas, while water molecules are simultaneously split to produce oxygen gas and hydrogen ions. The hydrogen ions then react with the remaining sodium ions in the solution to produce NaOH. The overall reaction can be represented by the following equation:

2NaCl + 2H2O → Cl2 + H2 + 2NaOH

The Ru-Ir oxide coating on the titanium mesh anode serves to increase its efficiency and durability by providing a highly conductive surface with good catalytic properties. The mmo mesh design also allows for a larger surface area, which enhances the anode's ability to facilitate the electrochemical reactions.

Overall, the use of Ru-Ir oxide coated titanium mesh anodes in the electrolysis of brine is a cost-effective and environmentally friendly method for producing chlorine and NaOH, with a wide range of industrial applications.
