Embodiment Construction
[0014] A graphene-reinforced ceramic lining material for hydraulic steel pipes, made of the following raw materials in parts by weight (kg): 54 pure aluminum powder, 159 red iron oxide, 18 cobalt nitrate, 18 nickel chloride, 37 ethyl orthosilicate , absolute ethanol 74, nano YZrO2 powder 10, sodium tetraborate 8.5, graphene 7, cerium trifluoride 1.5, lanthanum oxide powder 4, lithium carbonate 1.5, alcohol amine chelated titanate 0.6, deionized water.
[0015] According to claim 1, a graphene-reinforced ceramic lining material for hydraulic steel pipes is made by the following specific steps:
[0016] (1) Mix cobalt nitrate and nickel chloride, add it to absolute ethanol, stir and fully dissolve to form a mixed solution, then place it in a constant temperature water bath at 60°C, slowly add tetraethyl orthosilicate into the mixed solution, Heat the water bath to 80°C, stir for 40 minutes until the viscosity of the reactant increases, and form a transparent sol, which is gelled...
