Diameter 30mm platinum-coated titanium anode plate is called titanium-based metal oxide coated titanium anode (MMO). Also called DSA anode (dimensionally stable anode). It uses titanium as the substrate, and brushes the noble metal coating on the titanium substrate, so that it has good electrocatalytic activity and electrical conductivity. Compared with pristine graphite anodes and lead anodes, titanium electrodes have the following advantages:
-
The electrode size is relatively stable, and the distance between the electrodes will not change during the electrolysis process, ensuring that the electrolysis operation is carried out under the condition that the cell voltage is stable;
-
High catalytic activity and low working voltage;
-
The working voltage is low, so the power consumption is small, and the DC power consumption can be reduced by 10%---20%;
-
The working life of the titanium anode is long. The metal anode in the chlorine gas production by the diaphragm method is resistant to corrosion by chlorine and alkali. The life of the anode has reached more than 5~7 months, while the graphite anode is only 8 months;
-
It can overcome the dissolution problem of graphite anode and lead anode, and avoid the pollution of electrolyte and cathode products, thus greatly improving the purity of metal products.
Spend;
-
It can improve the current density and increase the electrolysis efficiency;
-
The oxides of noble metals and nails have oxidation resistance, so titanium electrodes have strong corrosion resistance;
-
It can avoid the short circuit problem after the deformation of the lead anode, so as to improve the efficiency of the current;
-
Titanium electrode is light in weight, which can reduce labor intensity compared with graphite anode and lead anode;
-
The shape and manufacture of the titanium matrix are relatively easy, and the high precision can be achieved:
-
Under the premise of no damage, the substrate can be tried repeatedly
