1.  Iridium tantalum (IR TA) coated electrode  
Oxygen resistant electrode is mainly used in oxygen evolution reaction, especially suitable for acidic electrolyte, such as sulfuric acid electrolyte of certain concentration, with ultra-low oxygen.It can be used in oxygen evolution electrolysis, also resistant to chlorine corrosion, and can be used in oxygen evolution and chlorine evolution electrolysis, such as sea water electrolysis.It is a good electrode material for oxygen evolution reaction in acidic medium, and the electrode materials available in such environment are limited.The coated electrode has been applied in Organic Electrolysis, such as cysteine, glyoxylic acid, succinic acid, etc., and can be used in the indirect oxidation of Cr3 + → Cr6 + in Organic Electrolysis, as well as in wastewater treatment for the oxidation of organic and toxic substances in water, such as CN -.It can also be used as auxiliary electrode in electroplating industry, such as auxiliary anode for Cr plating and auxiliary anode for electrolytic copper    
2. Ru Ti IR ternary coating electrode  
The coated electrode is suitable for ion-exchange membrane electrolysis because of its high resistance to oxygen corrosion
       
Coating index:             
The strengthening life (coating weight loss method) is 1.02mv/4h · cm2, and the service life is guaranteed for more than 5 years.It has been applied in large industrial cells                
3. Ru Ti Sn coating electrode  
The technology has been successfully developed and won the science and technology progress award of the Ministry of chemical industry
                   
The discharge potential of chlorine is not more than 1.12v and the overpotential is less than 20mV at the current density of 2000a/m2
                       
The polarizability is less than 30 mV/10 unit current density<5 N H2SO4, 1A/cm2 current density, and the service life is more than 1500 minutes
The above three indicators are better than the industry indicators (industry indicators are:potential 1.13 V, polarizability 40 mV/10, unit current density, strengthening life more than 1000 minutes)

4. Ti/Pt coated electrode
  Matrix metals:GR1, Gr2, TA1, TA2
  Working current range:<; 2000A/m2
  Temperature range:<; 80℃
  Coating metal:Pt (99.99%)
  Shape Shape:plate, tube, etc.
  Technical features:it is an insoluble anode.The platinum coating is firmly combined with the titanium base and has stable performance.It can replace pure gold and pure platinum anode for gold and other precious metal plating bath
  Should It can be applied to composite ceramic electroplating and other acidic and alkaline electroplating solutions
5. processing requirements of titanium based materials:
  Surface roughness:there is no relevant standard comparison, the rougher the better
  Surface flatness of plate mesh anode:thickness above 1.5 ≤± 0.5mm/m, thickness below 1.0 ≥ ± 1.0mm/m,
  Straightness of tubular anode:wall thickness above 1.5mm ± 0.5mm/m, wall thickness below 1.5mm ± 1.0mm/m
  Cutting tolerance of plate processing parts:the minimum can be controlled within ± 0.1 mm, and the general delivery tolerance is within ± 0.5 mm
6. precautions for the use of titanium anode products:
  DSA is not really insoluble anode, but the consumption rate is low.According to the application industry and specific use environment, our company can promise the guaranteed service life of 0.5-50 years
  1.Normal working current density 2000a/M ² If the current is too high, the reaction will be too intense and the anode life will be shortened
  2.The electrolyte should not contain cyanide ion and fluoride ion.These impurities will seriously corrode the titanium matrix
  3.The distance between anode and cathode can be set according to the specific situation, generally 5-25mm.Generally speaking, the electrode distance will increase the power consumption, and it should not be too small, otherwise the cathode scale on the cathode surface will easily cause the short circuit of the electrode plate
  4.It is forbidden to use the guide pole.Once the noble metal oxide coating is used as cathode, the reduction reaction will occur on the surface, which is easy to turn into metal element, so it can not be effectively combined with titanium substrate, resulting in the coating falling off.It can be considered to add acid to clean the plate surface regularly
  5.The working temperature of electrolyte should not be too high, the ideal temperature is 25-40 ℃
  6.Clean water should be used to wash the surface of the electrode plate when the machine is shut down, and it is not suitable to soak in the solution for a long time.If possible, it is best to maintain a small current of 2-5A to meet the cycle to protect the plate
  7.The installation and handling should be careful, and the coating surface should not be scratched, otherwise local corrosion will occur soon.
