Detailed Product Description: | Titanium anode full name titanium-based metal oxide coated titanium anode (MMO). Also called DSA anode. (Size and shape stable anode) It titanium substrate, brushing precious metal coating on a titanium substrate, it has good electrical conductivity, and catalytic activity. Titanium anode classification: According to the electrochemical reaction in the anode gas to distinguish precipitation, precipitation of chlorine, said chlorine evolution anode, such as ruthenium coated titanium electrodes: precipitation anodic oxygen evolution is called oxidation, such as iridium coated titanium electrodes chlorine evolution anode (ruthenium-based coating Titanium): high levels of chloride ion in the electrolyte: * environment in general and electrolysis of seawater electrolysis of salt water environment. Our products corresponding iridium ruthenium titanium anode, iridium, ruthenium titanium anode. Oxygen evolution anode (iridium coated titanium electrode): the electrolyte is generally * environment. Our products corresponding iridium anode tantalum, iridium, tantalum titanium anode. What is the role of the titanium anode metal oxide coating is? To promote the electrolysis process by covering the different coatings, enhanced electrical conductivity and catalytic activity and prolong the life of the anode in a different environment to achieve the desired effect of the use of titanium anodes metal oxide coating thickness problems: electrification of the catalytic reaction is mainly a noble metal coating only precious metal content of the requirements to ensure the normal operation of the anode product. The thickness is only a representation is mainly determined by the number of times the concentration of brush and solvent and how much precious metal content is not directly linked. Too thick coating actually easier to fall off. The main factors affecting the life of the anode which: 1. Current density: the current density and inversely proportional to the anode current increases life expectancy, the shorter the life of our company anode design anode current density within the 1500A / M2 recommend the current density should not exceed 1500A /. M2. Also try to avoid the current suddenly large and small 2. titanium substrate is generally used titanium anode substrate and material requirements in TA1 above, if the use of insufficient purity substrates, corrosion resistance of the anode is compromised life has a great influence 3. electrolyte containing fluoride ions ban, cyano and S ions influence the anode if life is relatively large. electrolyte chloride ion content should be controlled within 200PPM 4. inverted pole is the anode When the repair is often a way to adopt, you can make the old passivation coating has come off the substrate surface. Therefore, to prohibit the use of extremely 5. frequent power outages in the absence of current through the case, long coat in solution soak time will be greatly compromised. So when the anode does not work best with small current through maintaining generating circuit, not a long time when the anode remove rinse dry storage of 6 from the liquid. artificial damage: the anode surface can not have flawed, if even a small portion of the coating of a damaged scratch also make rapid corrosion of the anode passivation, and finally lead to failure in the installation and use of the anode so should gently. avoid short-circuiting bump 7. Prohibition of yin and yang in the case of power-pole connection caused a short circuit current is very big moment can burn 8. Temperature and life expectancy is inversely proportional to the anode. Our anode design temperature of 40-60 degrees is recommended temperature should not exceed 60 degrees titanium anode advantages (and lead anodes, tin anodes contrast): 1. dimensionally stable (insoluble matrix), pole pitch does not change, can guarantee cell voltage stability. 2. low voltage, low power consumption, high energy-saving than lead anodes 20% purity 3. 4. not produce anode mud, do not pollute the tank. 5. Light weight, can reduce labor intensity 6. The substrate can be used repeatedly electrode manufacturing principle is the use of sodium hypochlorite without diaphragm electrolysis, sodium hypochlorite generated by homogeneous secondary chemical reactions. Anodic reaction principle is sodium chloride into the water (tablet form) electrolysis. During electrolysis, the formation of sodium hypochlorite. The most appropriate salt concentration of 3% -5%. Sodium hypochlorite used in the generator electrode has an electrode plate and tubular electrode. Anodic coating titanium anode material can be selected. Mixed oxide coated titanium anode, long life, such coated titanium anode overpotential is relatively low, the high resolution chlorine current efficiency, energy-saving effect. |
