Basic knowledge and application of titanium anode
1- 0010010 nbsp;What is titanium anode?
The titanium anode is called a titanium-based metal oxide coated titanium anode (MMO). Also called DSA anode(Dimensionally Stable Anodes).It uses titanium as the substrate and brushes the precious metal coating on the titanium substrate to make it have good electrocatalytic activity and electrical conductivity.
Titanium anodes is classified 0010010 nbsp;according to gas released 0010010 nbsp;from 0010010 nbsp;the solution by 0010010 nbsp;the anode in the electrochemical reaction. If it is chlorine, we call it chlorine evolution anodes,such as ruthenium-coated titanium electrode.If it is oxygen, we call it oxygen evolution anodes 0010010 nbsp;, such as iridium coated titanium electrode and platinum-titanium mesh/plate anode. 0010010 nbsp;
Anode Products
The separation of 0010010 nbsp;gas is called Chlorine evolution anodes, 0010010 nbsp;such as ruthenium-coated titanium electrode; the separation of oxidation is called oxygen evolution anode, such as iridium coated titanium electrode and platinum-titanium mesh/plate.
Chlorine evolution anodes 0010010 nbsp;(ruthenium series coated 0010010 nbsp;titanium anode): high Chloride ion contained in electrolyte, common exist in hydrochloric acid environment and electrolytic seawater, electrolytic salt water environment,such as ruthenium-iridium titanium anode, ruthenium-iridium tin-titanium anode.
Oxygen evolution anodes (iridium 0010010 nbsp;series 0010010 nbsp;coated titanium anode): electrolyte is generally sulfuric acid environment. Common use iridium tantalum titanium anode, iridium tantalum tin titanium anode 0010010 nbsp;and high purity iridium coated titanium anode.
Platinum plated titanium anode 0010010 nbsp;(Platinum 0010010 nbsp;coated 0010010 nbsp;titanium mesh/platinum titanium plate): titanium as substrate, plated with the precious metal platinum. The plating layer is 0.5-5 um commonly. The dimond of the mesh is 3*6mm, 4*8mm and 12.5*4.5mm.

2- 0010010 nbsp;The advantages of titanium anode.
Our coating technology is brush.Titanium anodes has more advantages than other meterials.
1 0010010 gt; 0010010 nbsp;The dimension 0010010 nbsp;of titanium anode is stable and the distance between electrodes does not change during electrolysis, which can ensure that electrolysis operatio n can be carried out under the condition of stable tank voltage.
2 0010010 gt; 0010010 nbsp;Low working voltage, low power consumption, dc power consumption can be reduced by 10-20%
3 0010010 gt; 0010010 nbsp;Titanium substrate anode has excellent anti-corrosion, can work longer.
4 0010010 gt; 0010010 nbsp;Compared with graphite anode and lead dioxide anode, it can overcome the dissolution when working. Also avoid the contamination of electrolyte, inhance the purity of cathodic products.
5 0010010 gt; 0010010 nbsp;High current density, low overpotential, high catalytic activity of electrode, can effectively capture high production efficiency.
6 0010010 gt; 0010010 nbsp;It can avoid short circuit after lead 0010010 nbsp;dioxide 0010010 nbsp;anode deformation and improve current efficiency.
7 0010010 gt; 0010010 nbsp;Shape making is easy and can be made with high precision.
8 0010010 gt; 0010010 nbsp;Titanium substrate can be recyclable 0010010 nbsp;.
9 0010010 gt; 0010010 nbsp;With low overpotential characteristics, bubbles on the surface between electrodes and electrodes can be easily removed, which can effectively reduce the electrolytic cell voltage.
0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; Titanium Anode For Electrolysis
In electrolytic metallurgy, it can replace the conventional lead alloy anode, under the same conditions, the voltage can be reduced, and the power consumption can be saved. For example, electrolysis of zinc has always used a lead alloy anode containing a small amount of silver, strontium or calcium. It 0010010 nbsp;offen exist 0010010 nbsp;problems: the lead alloy electrode is unstable in size; the oxygen evolution potential is too high (about 800mV); corrosion occurs when the anode is polarized; lead ions are dissolved in the electrolyte, deposited on the cathode, contaminating the metal zinc, affecting product quality . Titanium anodes for electrowinning metals can overcome the drawbacks of lead alloy anodes, and are suitable for high current density operation and narrow pole spacing electrical conditions; not only for sulfate systems, but also for chlorine salt system, sulfate and chloride mixture system.
