OD　(mm)Length(mm)Output current(A)Lifetime (Year).

Titanium anode tube, also known as tubular anode or noble metal oxide titanium anode tube, is a metal oxide with electrocatalytic activity coated on a tubular titanium substrate. Titanium anode tubes are suitable for many environments, such as soil, fresh water, saline water and sea water, and are currently widely used products in the cathodic protection of shallow buried anodes and deep well anodes in pipeline storage tanks, and they are light in weight, long in service life and cost-effective. .
MMO tubular anode is a kind of auxiliary anode in impressed current cathodic protection system. It forms a cathodic protection system together with potentiostat, test pile, reference electrode, etc.
The mmo tubular anode can be welded and connected to the cable. It can be installed in one, or two or three to form a mmo anode string.

Coating System: Ruthenium/Iridium Metal Mixed Oxides
Application areas:
1. Continuous horizontal ground bed, discontinuous horizontal ground bed, shallow buried vertical ground bed
2. Condensate tank, heat exchanger, water treatment equipment
3. Underground storage tanks, ground storage tanks, water storage tanks
4. Anticorrosion of ships, roads, bridges, building steel bodies, etc.
mmo tubular anode coating type, thickness and anode size can be customized according to the user, which depends on the required current density, the medium environment used and the design life.
There are two main ways to use cathodic protection technology to delay the corrosion of steel structures:
1. Sacrificial anode cathodic protection
Sacrificial anode cathodic protection is to connect or weld metals or alloys with negative potential, such as aluminum, zinc or magnesium, on metal structures. The anode material is continuously consumed, and the released current supplies the protected metal structure to cathodically polarize, thereby achieving protection.
2. Impressed current cathodic protection
The cathodic current is applied to the protected metal by applying a direct current to make it cathodic polarization. In the past, sacrificial anode cathodic protection was generally used for the inner wall of the separator, but the temperature of the inner wall of the separator was high, the composition of the deposited water on the inner wall was complex, and the water quality may be acidic or alkaline. Therefore, the protection period of the sacrificial anode is short, and it is generally consumed in less than half a year. Sacrificial anode protection also exists protection dead angle. On the other hand, the cathodic protection potential of the sacrificial anode cannot be measured, the protection current cannot be adjusted, and the length of the protection period cannot be predicted.
In order to overcome the short service life and uneven protection of the sacrificial anode cathodic protection method, Shaanxi Youchuang Technology cooperated with some companies with strong scientific research strength to develop an impressed current cathodic protection method for the inner wall of the separator.
The number of anodes required is calculated according to the size and area of ​​each chamber, the composition and content of the electrolyte in the sewage, and the required protective current density. The titanium-based tubular mixed metal oxide anode is used as the auxiliary anode to be fixed at the bottom of the separator. A silver/silver chloride reference electrode or a high-purity zinc reference electrode is used on a support at a certain height in the aqueous phase. All cables in the tank are led out through special safety leak-proof joints, and then lead to the corresponding contacts of the potentiostat.
3. Anode (auxiliary) for inner wall anticorrosion cathodic protection
Impressed current cathodic protection using mixed metal oxide tubular anode. Install 3 anodes of 25*700mm in each separator, and install 1-2 anodes in each cavity. The anodes are installed with brackets. The height of the brackets is greater than 300. The original fixing points in the separator are used, but the anode and the separator must be guaranteed. body insulation. The reference electrode is mounted on the tank wall in the same way as the mixed metal oxide anode.

Introduction and principle of titanium Anode

Titanium anodes are electrochemical cells made from pure titanium, or a titanium alloy, that are commonly used in various electroplating and electrolysis applications. The main principle of a titanium anode is based on the concept of electrochemical oxidation-reduction reactions that occur when an electric current is passed through a solution or an electrolyte.

During electrolysis, the titanium anode acts as the positive electrode, and it is where oxidation reactions occur. The anode is surrounded by a solution, which contains positively charged ions, known as cations. These cations are attracted to the negatively charged cathode, and they lose electrons at the anode. The loss of electrons causes the cations to undergo oxidation, resulting in the formation of new compounds and the release of oxygen gas.

The principle of a titanium anode is based on the unique properties of titanium, which include excellent corrosion resistance, high strength-to-weight ratio, and good electrical conductivity. These properties make titanium an ideal material for use in harsh environments, where other metals might fail due to corrosion or other factors.

The anode’s performance is dependent on the electrochemical properties of the solution, as well as the type of electrode used. For example, in some applications, a titanium anode may be coated with a thin layer of metal oxide, such as iridium oxide, to increase its catalytic activity and improve its performance. Additionally, the size and shape of the anode may be optimized to ensure efficient mass transfer and current distribution, which can impact the overall effectiveness of the electrochemical process.

The history of titanium anode

The history of titanium anodes can be traced back to the mid-20th century when researchers began to investigate the use of titanium as an electrode material. The first titanium anodes were developed in the s, and they quickly gained popularity due to their unique properties, including high corrosion resistance and durability.

One of the earliest applications of titanium anodes was in the chlor alkali industry, where they were used to produce chlorine and other chemicals. Titanium anodes quickly replaced more traditional materials such as graphite and lead, which were less efficient and more prone to corrosion.

How are titanium anodes produced?

Titanium anodes are typically produced using a multi-step process that involves several stages of manufacturing and coating. Here’s a general overview of the steps involved in producing titanium anodes:

1. Cutting and Shaping: The first step in producing a titanium anode is to cut and shape the titanium substrate to the required size and shape. This may involve using a saw or other cutting tool, as well as a lathe or other machinery to shape the anode to the desired dimensions.

2. Surface Preparation: Once the anode has been shaped, the surface of the titanium substrate is cleaned and prepared for coating. This may involve a chemical etching process to remove any impurities or contaminants from the surface of the substrate.

3. Coating: The titanium anode is coated with a layer of mixed metal oxide (MMO) using an electrochemical process known as anodization. During anodization, an electrical current is applied to the titanium substrate, which causes a layer of MMO to form on the surface. The thickness and composition of the MMO layer can be adjusted to suit the specific requirements of the application.

4. Quality Control: Once the anode has been coated, it is inspected to ensure that the MMO layer is uniform and free from defects. Quality control measures may include visual inspection, electrical testing, and other techniques to ensure that the anode meets the required specifications.

5. Packaging and Shipping: The final step in producing a titanium anode is to package it for shipment. The anode may be wrapped in protective materials, such as bubble wrap or foam, to prevent damage during transport. It may also be labeled with relevant information, such as the type of coating, the date of manufacture, and any other relevant details.

Overall, the production of titanium anodes is a complex process that involves several stages of manufacturing and coating. The specific details of the process can vary depending on the type of anode, the application, and other factors
