AI Technical Summary
Existing inverted expansion rings for energy storage water tanks are insufficient in terms of strength, rigidity, and wear resistance, and the coating has poor compatibility with the substrate interface, resulting in limited overall load-bearing capacity and service life.
A combination of zirconium-modified aluminum phosphate adhesive, silicon nitride magnesium powder, and composite nano-silica is used to construct a high-strength inorganic cross-linked framework through Zr-OP, Si-OP, and Si-O-Al covalent bonds. This framework is then combined with composite nano-silica and epoxy resin to form a continuous and dense protective layer, achieving a tight bond between the coating and the substrate.
It significantly improves the tensile strength, yield strength, and Rockwell hardness of the expansion ring, reduces plastic deformation and coating peeling during friction, enhances long-term wear resistance, and ensures the stability of the inverted installation of the energy storage tank and the service life of the equipment.
