But the most significant difference from the protection of colors is to limit the size of the protected product size baths or shops where they metalliziruyutsya zinc. Steamer into the bathtub is not vsunesh. That's how the combine is still industrialists painting galvanized. Exit suggested itself – to invent anti-rust coating that combines the advantages and paint and galvanizing performance! ZINGA-double protection challenge to scientists, it seems, was simple – a zinc filled paint effective as zinc. Learn more about this topic with the insights from Gazprom. But this effect did not, although 'improvements' were there – invent new colors. The secret lay in the fact that cathodic protection is required for electrical contact between zinc and steel, and, the contact is better and purer zinc, the more effective cathodic protection. After experimenting with various zinc-filled paints, which do not provide such a contact, started on the steel surface apply pure zinc (dust) – the contact was excellent and protection work, but zinc is not kept on the surface. It is in the binder was a snag over a long fought Corrosion many countries *.
Footnote *: Had the Cold Galvanized 'in the USSR. In particular, in 1991, based on scientific research of scientists of the Sverdlovsk branch of the USSR Academy of Sciences (in preparation etilsilikatnogo binder attended Leningrad and scientists) Donetsk by 'COMPUTER CO.' was organized by the fine production of zinc and on its basis – the zinc coating, which was treated steel pipes of large diameter (inside and outside), water pipes for residential houses and so-called. tanks-accumulators. Branch of the company organized a demonstration in Kiev, the processing section of the bridge to them. Paton, who was in disrepair, but the money to protect the bridge budget has not allocated and it died away. Donetsk firm still Cold galvanized steel handles (including safety devices), but now she's zinc powder imported from Germany and Poland, and the only binder is made to domestic Zaporizhzhya Plant 'Kremnypolymer'.
