Titanium anodes advantages

1, titanium anode long life, diaphragm production of chlor-alkali industry, metal anode resistance to chlorine and alkali corrosion, anode life has been more than 6 years, while the graphite anode only 8 months.

2, can overcome the graphite anode and lead anodic dissolution problems, to avoid the electrolyte and cathode products pollution, which can improve the purity of metal products.

3, can improve the current density, diaphragm production of chlor-alkali, graphite anode current density of 8A / dm2, Titanium anodes can be doubled to 17A / dm2, so that in the electrolysis plant, the same conditions under the electrolytic tank, the output can be increased by 1 times to improve the production capacity of a single tank, effectively improve the labor productivity. In the high operating current density for electrolysis, the use of titanium anode is best suited.

4, due to the use of metal anode, chlorate electrolytic cell high temperature, high current density operation possible. Use of metal anodes improves the electrolytic cell structure, reduces power consumption, accelerates the chemical reaction of hypochlorite chlorite, thereby improving production performance.

5, using the DSA, mercury and diaphragm methods of salt electrolytic cell design concepts and operating conditions can be improved, energy consumption can be reduced. DSA low over-potential characteristics, the electrode between the surface and the electrode bubble is easy to exclude, is the metal anode electrolytic cell voltage reduction of the principal reasons.

As the titanium anode has many advantages, its development makes the chlor-alkali industry to achieve significant economic benefits, so soon in the world to promote the use. Chlor-alkali production capacity, the world's about 41 million tons / year, the use of titanium anode is not less than 70%, titanium anode known as chlor-alkali industry a major technological revolution. Subsequently, titanium anodes in many electrolysis industry has also been extensively used.

6, the anode size is stable, the electrolysis process between the electrode does not alter the distance, to ensure that the electrolytic operation in the case of tank voltage stability.

7, to avoid lead anode deformation after the short circuit problem, which can improve efficiency.

8, titanium anodes lightweight, can reduce labor intensity.

9, switch productions are easy, can be highly accurate.

10, the working voltage is low, so the power consumption is small, can save power consumption. DC power consumption can be reduced by 10% to 20%. Titanium anode operating voltage is depressed main reasons: 1) active coating titanium anode on the chlorine and oxygen over-potential are relatively low. Brine electrolysis production of chlor-alkali, the titanium anode on the chlorine over-potential is low, at 1A / cm2 than the graphite anode low 140mV; 2) can reduce the "bubble shielding effect", the metal anode surface bubble is relatively small, and detachment quickly, The air gap is greatly reduced, the ohmic drop between the poles is about 700mV, the bubble diameter is about 3mm; 3) the resistance of the anode structure is reduced; and 4) the distance between the poles is shortened.

The 20th century, 60 years, the world's salt electrolysis industry annual power consumption of about 150 billion degrees, the use of metal anode, the annual energy savings of about 300 million degrees.

11, chlor-alkali production, the use of titanium anode, is the product of high quality. High purity chlorine, non-CO2, alkali concentration, can save heating steam, saving energy consumption.

12, corrosion resistances, and can be in many corrosive, with special requirements of the electrolytic medium work.

13, the base metal titanium can be repeated use.

14, the emergence of metal anode, the use of chlor-alkali industry in the recent emergence of the latest ion-exchange membrane electrolysis technology to design and implementation of industrialization.
