一种大型稀土电解槽防渗漏材料
Abstract:
一种大型稀土电解槽防渗漏材料，包括SiO2、Al2O3和CaO，所述的SiO2和Al2O3的质量比为0.59-1.76:1，所述的防渗漏材料在铺设时分为内外两层，内层为耐火防渗漏层，其中SiO2和Al2O3总质量占比大于98％，CaO质量占比低于0.5％，其他杂质质量占比低于1.5％，外层为主防渗漏层，其中SiO2和Al2O3总质量占比大于90％，CaO质量占比8％-10％，其他杂质质量占比低于2％。本发明的防渗漏材料可为稀土电解槽大型化提供保障，促进稀土行业往高产量、低能耗的绿色方向发展。
Abstract(English):

An antiseep material for a large-size rare earth electrolytic cell includes SiO2, Al2O3 and CaO. The mass ratio of the SiO2 to the Al2O3 is 0.59-1.76:1. The material has inner and outer layers duringpavement. The inner layer is a refractory antiseep layer, wherein the total mass percentage of the SiO2 and the Al2O3 is more than 98%, the mass percentage of the CaO is less than 0.5%, and the mass percentage of other impurities is less than 1.5%. The outer layer is a main antiseep layer, wherein the total mass percentage of the SiO2 and the Al2O3 is more than 90%, the mass percentage of the CaOis 8% to 10%, and the mass percentage of other impurities is less than 2%. The material can provide guarantee for a large-scale rare earth electrolytic cell, and promotes development of the rare earthindustry to the green direction of high output and low energy consumption.
