Ambient temperature cured TiB2 cathode coating for aluminum electrolysis
Trans. Nonferrous Met. Soc. China Vol. 13 No. 3 Jun. 2003,-0001,():
The concept of ambient temperature curable TiB2 cathode coating was put forward, and the ambient temperature curable TiB2 cathode coating was prepared successfully. Differing from the previous TiB2 cathode coating solidified approximately at 200 ℃, the ambient temperature curable TiB2 cathode coating can be solidified at room temperature, so the heating equipment is not necessary, which simplifies the preparation process and facilitates the industrial application of TiB2 cathode coating. Many kinds of resin and curing agent were investigated. On the above-mentioned basis, the ambient temperature curable TiB2 cathode coating was prepared with furan resin 5500 mixed with complex resins B as carbon binder and DXG1 as curing agent in 24h. The results show that the properties of prepared coating are excellent, the electrical resistivity is 29.8 μΩ·m, the compressive strength is 33. 6 MPa, which are all better than the relevant properties of partially graphitized cathode carbon block for aluminum electrolysis prescribed by the GB 8744-88. SEM morphologies show that the section morphology of the TiB2 coating is unaltered during the electrolysis test, the TiB2 coating can be used in aluminum electrolysis industry to save energy and prolong the life of aluminum electrolysis cell.
