Smart ZIC is a construction method that applies cold spray technology devised during the development of Russian fighter jets, and forms a zinc coating by spraying powdered zinc onto metal surfaces at supersonic speed using a special spray gun. This is a construction method. The sprayed zinc powder is below its melting point, which is different from traditional metal spraying. The formed zinc coating has extremely high sacrificial corrosion protection performance (even if the base iron is scratched, the surrounding zinc will dissolve first and protect the iron), and it can be used as a corrosion-proofing base for painting. functions as For areas with particularly severe corrosion, by mixing alumina powder, which is also used for blasting, it is possible to prepare the substrate and form a zinc coating at the same time, saving labor in cleaning work (removing dirt and rust). It is also possible.
We are currently considering applying this Smart ZIC as a corrosion-proofing base for repainting the weak points of steel bridges, such as high-strength bolt joints and the ends of main girders. Although it is not efficient to apply to large areas like metal thermal spraying, we are developing nozzles that are easier to apply to narrow areas and semi-automating the installation, with the aim of repairing locally corroded areas. going.
