Pierwszenstwo: Opublikowano: 20.VI.1968 55547 KI. 40 c, 1/00 MKP C 22 d dj UKD 669.2.8.087.12 Wspóltwórcy wynalazku: prof. dr Ludwik Wasilewski, dr inz. Danuta Krupkowa, inz. Mieczyslaw Kapczynski, mgr Jan Nosel, dr inz. Kazimierz Zmudzinski, inz. Antoni Czuba Wlasciciel patentu: Instytut Metali Niezelaznych, Gliwice (Polska) Sposób poprawienia jakosci osadów elektrolitycznych i Przedmiotem wynalazku jest sposób poprawie¬ nia jakosci osadów elektrolitycznych metali z roz¬ tworów wodnych. Dotychczas uzywa sie do tego celu znane dodatki koloidalne jak: zelatyne, gume arabska, klej stolarski i inne. Wada stosowanych dodatków koloidalnych jest maly wplyw na kato¬ dowa wydajnosc pradu i mala gladkosc osadów.Celem wynalazku jest powiekszenie skutecznosci dodatków koloidalnych majacych wplyw na prze¬ bieg procesów katodowych. Zagadnienie to zostalo rozwiazane przez wprowadzenie do elektrolitu czesciowo shydrolizowanej skrobi. Skrobie ziem¬ niaczana poddaje sie hydrolizie lugiem sodowym wedlug znanego sposobu i w postaci roztworu dozuje sie do elektrolizerów. Ilosc dodatku skrobi zalezna jest od rodzaju i stopnia zanieczyszczenia elektrolitu.Na przyklad przy elektrolizie cynku stosuje sie 10 dodatek czesciowo shydrolizowanej skrobi w ilosci 10—20 mg/l elektrolitu.W wyniku zastosowania dodatku skrobi uzysku¬ je sie wyzsza wydajnosc pradu co pozwala zmniej¬ szyc jednostkowe zuzycie energii elektrycznej oraz poprawienie gladkosci i zwartosci osadów kato¬ dowych, co zwieksza uzysk przetopu metalu ka¬ todowego. PLPriority: Published: 20.VI.1968 55547 IC. 40 c, 1/00 MKP C 22 dj UKD 669.2.8.087.12 Co-authors of the invention: prof. Dr. Ludwik Wasilewski, Dr. Danuta Krupkowa, Dr. Mieczyslaw Kapczynski, Dr. Jan Nosel, Dr. Kazimierz Zmudzinski, Dr. Antoni Czuba The owner of the patent: Instytut Metalali Niezelaznych, Gliwice (Poland) improving the quality of electrolytic metal deposits from aqueous solutions. So far, known colloidal additives have been used for this purpose, such as: gelatine, gum arabic, carpentry glue and others. The disadvantage of the colloidal additives used is their low effect on the cathode output of the current and the low smoothness of the deposits. The aim of the invention is to increase the effectiveness of the colloidal additives influencing the course of cathode processes. This problem was solved by introducing partially hydrolyzed starch into the electrolyte. The potato starch is hydrolyzed with sodium hydroxide according to a known method and is dosed in the form of a solution into the electrolysers. The amount of starch added depends on the type and degree of contamination of the electrolyte. For example, in the electrolysis of zinc, the addition of partially hydrolyzed starch in the amount of 10-20 mg / l electrolyte is used. sewing unit consumption of electricity and improving the smoothness and compactness of cathode deposits, which increases the yield of cathode metal remelting.
