Do ich wyro¬ bu proponowano stosowac azbest nasycony kwa¬ sem krzemowym lub krzemionke, tlenek glino¬ wy, tlenek zelaza itd.Stwierdzono, ze przepony uformowane z pro¬ szkowanej mieszaniny zawierajacej okolo 50 czesci wagowych kaolinu, 40% czesci wagowych dwutlenku krzemu i 10% czesci wagowych spro¬ szkowanej masy porcelanowej, przesianej przez sito o 4 900 oozlkach na 1 cm2 i wypalone w tem¬ peraturze okolo 700° C usuwaja wspomniane nie¬ dogodnosci, a mianowicie sa one wytrzymale i daja zelazicyjanek potasu o czystosci nadajacej sie do analizy.Przepony wykonane sposobem wedlug wyna¬ lazku sa bardzo trwale, nie wykazujac sladów zuzycia i daja wysoka wydajnosc pradowa do¬ chodzaca do 94%. Ponadto wydajnosc elektro¬ lizy jest równiez wysoka wynosi bowiem 93% wydajnosci teoretycznej. PLPublished on May 30, 1956. ******* Jot * 3 / ^ 0 POLISH PEOPLE'S REPUBLIC PATENT DESCRIPTION No. 39174 KI. 12 h, 3 Wojewódzki Związek Spóldzielni Pracy *) Bydgoszcz, Poland Method of making electrolysis diaphragms, especially for electrolytic oxidation of potassium iron cyanide to potassium iron cyanide Patent valid since 25 July 1955 Known electrolysis diaphragms, especially for electrolytic iron oxidation The ferric cyanide potassium is not suitable for wider use, because it does not show sufficient mechanical strength or it contaminates the obtained product. For their manufacture it has been proposed to use asbestos saturated with silicic acid or silica, alumina, iron oxide, etc. It has been found that diaphragms formed from a glazed mixture containing about 50 parts by weight kaolin, 40 parts by weight silicon dioxide and 10 The percent by weight of the pulverized porcelain mass, sieved through a sieve with 4,900 beds per cm2 and fired at a temperature of about 700 ° C, remove the above-mentioned disadvantages, namely they are strong and give potassium ferrocyanide with a purity suitable for analysis The diaphragms made according to the invention are very durable, show no signs of wear, and give a high current efficiency of up to 94%. Moreover, the electrolysis efficiency is also high, being 93% of the theoretical one. PL
