Titanium electrode mesh bucket for electrolytic plating

The application range of titanium mesh barrel anode for electrolytic plating is wide, mainly covering the following aspects:

Electroplating industry

(1) Metal electroplating:
Titanium mesh barrel anode can be used in the deposition process of electrolytic chromium, copper, nickel, zinc and other metals. As the anode in the electroplating tank, it is used to enhance the electrochemical oxidation reaction of cations and promote the uniform deposition of the plated metal on the plated substrate.

Application areas include but are not limited to electroplating zinc (such as steel plate zinc plating), electroplating hard chromium, electroplating nickel, electroplating tin (such as steel plate tin plating), electroplating copper (including copper foil production and copper foil post-processing), etc.
In the electroplating process, the excellent corrosion resistance, high catalytic activity and long life of titanium anode can ensure the stability of electroplating quality and improve production efficiency.

(2) Precious metal electroplating:
Titanium mesh barrel anode is also suitable for precious metal electroplating processes such as gold plating, silver plating and palladium plating, which can meet the electroplating needs of high-end products.

(3) Other electroplating applications:
For example, in the anodizing treatment of aluminum foil, titanium anode also performs well.

 

 

Platinum coating: Platinum is a precious metal with good catalytic activity and stability, suitable for electrolytic processes that require high catalytic activity, such as hydrogen production.
Ruthenium-iridium coating: Ruthenium-iridium coating has excellent corrosion resistance and catalytic activity, and is particularly suitable for electrolytic processes that require strong oxidation, such as wastewater treatment.
Other coatings: such as iridium-tantalum coating, platinum coating, etc., are also widely used in different electrolytic processes.

 

 

 

 

 

1. Hydrogen production by electrolysis of water
In the process of hydrogen production by electrolysis of water, the titanium mesh barrel anode as an anode can stably produce oxygen, and due to its excellent corrosion resistance and electrochemical properties, it ensures the continuity and efficiency of the hydrogen production process.
The high catalytic activity of the titanium anode helps to reduce the overpotential of water electrolysis and improve the electrolysis efficiency, thereby increasing the output and purity of hydrogen.
2. Wastewater treatment
The titanium mesh barrel anode can be used to treat wastewater by electrolytic oxidation, especially high-concentration organic wastewater, wastewater containing acidic or alkaline substances, and industrial wastewater.
It can effectively remove organic matter and pollutants in wastewater at high voltage and high current density, and improve water quality.
3. Other fields
Chemical pharmaceuticals: Titanium anodes are used to prepare a variety of organic compounds and pharmaceutical intermediates, and the yield and purity are improved by electrochemical synthesis.
Acid-base electrolysis: In the electrolysis of strong acid and alkali solutions such as hydrochloric acid, sulfuric acid, and hydrofluoric acid, titanium anodes can replace traditional lead and platinum electrodes, and have good corrosion resistance and electrocatalytic properties.
Resistance heating: In some industrial processes, titanium anodes can be used for resistance heating, such as heating catalyst reactors in the petrochemical industry.
Air pollution control: Titanium anodes can be used for electrochemical treatment of atmospheric pollutants, such as the removal of NOx and SOx.

 

1. Titanium mesh pretreatment
Select high-quality titanium mesh as the substrate.
Grind and clean the titanium mesh to remove impurities such as oil and oxide on the surface and improve the adhesion of the coating.
2. Catalyst coating
Apply iridium and other precious metals as catalysts on the surface of the titanium mesh. This step is to improve the catalytic activity of the titanium mesh during the electrolysis process and promote the electrolysis reaction.
3. Electrolytic cell preparation
Determine the size, shape and material of the electrolytic cell according to production requirements.
Put the treated titanium mesh anode into the electrolytic cell, and install the cathode and electrolyte circulation system.
4. Electrolyte preparation
Prepare a suitable electrolyte according to the requirements of electroplating. The electrolyte is usually composed of main salt, conductive salt, additives, etc., and its concentration, temperature and pH value must be strictly controlled to ensure the quality of electroplating.
5. Electrolytic plating
Pour the prepared electrolyte into the electrolytic cell.
Turn on the power supply and adjust the current and voltage to the set value.
During the electrolysis process, the titanium mesh anode acts as the positive electrode, and an oxidation reaction occurs in the electrolyte. At the same time, a reduction reaction occurs on the cathode, causing the metal ions to deposit on the cathode surface to form a coating.
6. Post-treatment
After the electrolytic plating is completed, the plated parts are taken out for post-treatment such as cleaning and drying.
The coating is quality tested to ensure that the performance indicators such as coating thickness, adhesion, and corrosion resistance meet the requirements.

 

 

 

 

(1) During the entire electrolytic plating process, the concentration, temperature, pH value, current and voltage of the electrolyte need to be strictly controlled to ensure the quality of electroplating.
(2) The titanium mesh anode needs to be regularly inspected and maintained during use to ensure the activity of the catalyst on its surface and the uniformity of the plating layer.
(3) The waste liquid and waste gas generated during the electrolytic plating process need to be properly handled to avoid harm to the environment and human health.
