Features: Dry construction of impervious material without water and has simple construction, good insulation effect, imperviousness etc.Its working principle is in the condition of high temperature materials and metal liquid alkali reaction, formed on the surface of isolation layer, prevent sodium to the cathode block infiltration protection of the cathode block, so as to prolong service life of the electrolytic tank, while reducing power consumption.
