Description

Известны сульфатные способы изготовлени  активной железной массы дл  отрицательных электродов щелочных аккумул торов. Однако эти способы сложны.Sulfate methods are known for making active iron masses for negative electrodes of alkaline batteries. However, these methods are complex.

Отличительна  особенность описываемого способа состоит в том. что окислы железа, полученные сжиганием железных листов в атмосфере кислорода, подвергают тонкому помолу и обжиганию при температуре 500-570° в течение около 6 часов без доступа воздуха и обожженную массу замешивают с водой.A distinctive feature of the described method is. that iron oxides obtained by burning iron sheets in an oxygen atmosphere are subjected to fine grinding and firing at a temperature of 500–570 ° for about 6 hours without air access and the burned mass is kneaded with water.

Грубый прокат сжигают в струе кислорода. В этих услови х предварительно нагретое до 600-700° железо сжигаетс  автотермично. При этом .получаютс  окислы железа РезО4 с некоторым избытком FeO.Rough rolled products are burned in a stream of oxygen. Under these conditions, the preheated iron to 600-700 ° C is burned autothermally. In this case, iron oxides of ResO4 are obtained with a certain excess of FeO.

Будучи размолоты и просе ны, эти окислы близки по составу к активной железной массе, но по электрическим данным не удовлетвор ют техническим требовани м на активную массу.Being crushed and sifted, these oxides are close in composition to the active iron mass, but according to the electrical data they do not satisfy the technical requirements for the active mass.

Дл  повышени  электрических данных массы последнюю после помола подвергают термической обработке (томлению) в трубчатой печи без доступа кислорода при температуре 520-570° в течение пор дка шести часов. При этом избыточное количество FeO термически диссоциирует , и в массе увеличиваетс  содержание свободного металлического железа и .To increase the electrical mass data, the last after grinding is subjected to heat treatment (languor) in a tube furnace without oxygen access at a temperature of 520-570 ° for about six hours. In this case, an excess amount of FeO dissociates thermally, and the content of free metallic iron and in the mass increases.

В дальнейшем активна  железна  масса подвергаетс  обработке водой и используетс  дл  изготовлени  отрицательных электродов щелочных аккумул торов.Subsequently, the active iron mass is subjected to water treatment and is used to make the negative electrodes of alkaline batteries.
