Chor-alkali industry is to prepare chlorine and caustic soda by electrolysising saturated salt aqueous solution. This production technology has over 100 years. Platinum, magnetic iron oxide, carbon and artificial graphite have been tried in chor-alkali industry production technology. These anodes are not fit to chor-alkali industry. The titanium eletrodes coating precious metals mixed oxide have many advantages. The titanium anodes have a strong corrosion resistance, low overpotential of chlorine, good conductivity, high mechanical strenghth, workability,low price and so on. Qixin Titanium Co.,Ltd. has strong technical support and formed a complete system of research, production and testing.
The service life of the ion-exchange membrane anode with special coating is up to six years in saturated salt solution(current density 3000-4000A/m2).
