Dry barrier mix Kiln refractory material Impermeable Castable Refractory
for Electrolytic cell
Dry barrier mix produced by Jundao is formed by dry vibration, it can react with the electrolyte that leaks along the cracks of the cathode magnet, and produce a high viscosity liquid phase which can effectively prevent further leakage, thus reducing the current efficiency of electrolytic bath due to the leakage of electrolyte and extending the service life of the electrolytic cell.
Dry barrier mix can strengthen the thermal insulation capacity of the bottom of the cell, reduce the heat loss of the bottom of the cell, increase the temperature of the cathode carbon block itself, and reduce the temperature gradient between the bottom and the top of the cathode carbon block.
Dry barrier mix Features:
High leakage resistance
Convenient construction
Low themal conductivity
Dry barrier mix is mainly used in the bottom of electrolytic cell, the lower part of the cathode magnet.
