The titanium anode is the anode in the titanium based metal oxide coating.According to their different surface catalytic coatings,they have oxygen evolution and chlorine evolution functions.Generally,electrode materials should have good conductivity,small electrode distance variation,strong corrosion resistance,good mechanical strength and processing performance,long service life,low cost,and good electrocatalytic performance for electrode reactions.Currently,titanium is the metal that can best meet the above comprehensive requirements,and industrial pure titanium TA1TA2 is generally used.

Types of titanium anodes:soluble anodes and insoluble anodes;Titanium anodes for chlor alkali industry;Titanium anode for electroplating;Lead and lead alloy anodes;Coated titanium anode.

Advantages of titanium anode:

1.Titanium anodes have a long working life.

2.It can overcome the problem of dissolution of graphite anode and lead anode,

3.Can increase current density.

4.The use of metal anodes improves the structure of the electrolytic cell,reduces energy consumption,accelerates the chemical reaction between hypochlorite and gas chlorate,and thus improves production performance.

5.The design concept and operating conditions of the salt electrolysis cell using DSA,mercury method,and diaphragm method have been improved,

6.The anode size is stable,and the distance between electrodes does not change during the electrolysis process,ensuring that the electrolysis operation can be carried out under stable cell voltage.

7.It can avoid short circuit problems caused by deformation of lead anodes,thus improving current efficiency.

8.Titanium anodes are lightweight and can reduce labor intensity.

9.The switch is easy to make and can achieve high precision.

10.The working voltage is low,so the energy consumption is small,which can save energy consumption.

11.In chlor alkali production,the use of titanium anodes results in high product quality,high purity of chlorine gas,no CO2,high alkali concentration,which can save heating steam and energy consumption.

12.Strong corrosion resistance and can work in many highly corrosive and special requirements electrolytic media.

13.The base metal titanium can be reused multiple times.

14.The emergence of metal anodes has enabled the design and industrialization of the latest ion membrane electrolysis technology that has emerged in the chlor alkali industry recently.

Titanium anodes are mainly used in wet metallurgy industries such as electroplating(deep hole high demand electroplating of copper and electroplating of gold in the circuit board industry)and electrolysis.
