Description
Najdluzszy czas trwania patentu do dn. 12 stycznia 1940 r.Wynalazek niniejszy dotyczy uzywanej przy elektrolitycznym wyrobie nadboranu sodu katody z materialów, bedacych do¬ brem! przewodnikami pradu, dzialajacych rozkladajaco same przez sie lub w swoich zwiazkach. Przy opracowaniu tego zada¬ nia wyjasnilo sie, ze korzystnie jest stoso¬ wac katody z materjalów, przy których potencjal wodoru równa sie zeru albo po¬ siada niewiele wieksza od zera wartosc, jak to ma miejsce, np., przy zelazie, sre¬ brze, niklu, miedzi. Innemi slowy, uzywa sie materjalów, które nie wykazuja kato¬ dowego napiecia lub bardzo male. PLThe longest term of the patent until January 12, 1940 The present invention relates to a cathode used in the electrowinning of sodium perborate from materials that are good! current conductors, acting decomposing by themselves or in their relationships. When developing this task, it became clear that it is advantageous to use cathodes made of materials where the hydrogen potential is equal to zero or has a value slightly greater than zero, as is the case, for example, with iron, silver. , nickel, copper. In other words, materials are used that exhibit no or very little voltage. PL
