Description
Czystosc cynku elektrolitycznego zalezy poza innymi czynnikami przede wszystkim od rodza¬ ju anod, uzytych do elektrolizy. Przy uzyciu anod z czystego olowiu czystosc cynku, jaka mozna bylo dotychczas osiagnac, nie przekracza¬ la 99,97%. Zastosowanie anod z olowiu z do¬ datkiem 1% srebra pozwolilo osiagnac czystosc cynku, wynoszaca 99,98%, a w wyjatkowo po¬ myslnych warunkach nawet 99,99%.Przedmiot wynalazku dotyczy anod ze stopu olowiu, srebra i arsenu, przy czym arsen moze byc ewent. zastapiony antymonem. Przy uzy¬ ciu anod z takiego stopu mozna zawsze osiagac czystosc cynku, wyrazajaca sie liczba 99,99%, a w szczególnie sprzyjajacych warunkach na¬ wet jeszcze wyzsza. Czystosc taka jest koniecz¬ na ze wzgledu na wymagania techniczne, sta¬ wiane obecnie cynkowi elektrolitycznemu.Anody ze stopu olowiu, srebra i arsenu nie tylko umozliwiaja osiagniecie wyzszej czystosci cyriku niz dotychczas, lecz ponadto sa znacznie odporniejsze na .korozje, co wplywa na zwiek¬ szenie ich trwalosci.Anody wedlug wynalazku pozwalaja otrzy¬ mywac cynk o zawartosci olowiu, nie przekra¬ czajacej 0,006%, dzieki czemu moze on byc uzy¬ ty do wysokowartosciowych stopów cynkowych.W pomyslnych warunkach anody te pozwa¬ laja obnizyc zawartosc olowiu w cynku do 0,003%. Taki cynk nadaje sie juz do wyrobu najwyzszych gatunków stopów cynkowych. PLThe purity of electrolytic zinc depends, among other factors, primarily on the type of anodes used for electrolysis. When pure lead anodes are used, the purity of zinc that has so far been achieved has not exceeded 99.97%. The use of lead anodes with an addition of 1% silver made it possible to achieve a zinc purity of 99.98%, and in exceptionally favorable conditions even 99.99%. The subject of the invention relates to anodes made of an alloy of lead, silver and arsenic, with arsenic being able to to be possibly replaced with antimony. When using anodes made of such an alloy, it is always possible to achieve a zinc purity of 99.99% and, under particularly favorable conditions, even higher. Such purity is necessary due to the technical requirements currently imposed on electrolytic zinc. Anodes made of an alloy of lead, silver and arsenic not only make it possible to achieve a higher purity of the circus than before, but are also much more resistant to corrosion, which affects the animal. Increasing their durability. The anodes according to the invention make it possible to obtain zinc with a lead content not exceeding 0.006%, thanks to which it can be used for high-quality zinc alloys. Ideally these anodes reduce the lead content in zinc. up to 0.003%. Such zinc is already suitable for the production of the highest grades of zinc alloys. PL
