Abstract

Procedimiento para la producción de ánodos metálicos, especialmente de ánodos de titanio, para la obtención electrolítica de dióxido de manganeso, con una base consistente en un metal pasivable y una capa de cubrición activadora generada por deposición activadora generada por deposición de metales nobles, que cubre por lo menos parcialmente a la superficie de la base, caracterizado porque, después de que los metales nobles han sido aplicados sobre la superficie de la base de ánodo, ésta última es calcinada a temperaturas entre 700 y 1.100ºC.Procedure for the production of metallic anodes, especially of titanium anodes, for the electrolytic obtaining of manganese dioxide, with a base consisting of a passivable metal and an activating covering layer generated by activating deposition generated by noble metal deposition, covering at least partially to the surface of the base, characterized in that, after the noble metals have been applied on the surface of the anode base, the latter is calcined at temperatures between 700 and 1100 ° C.

Изобретение относитс  к электрохимическому производству, в частности к анодам, используемым при электролитическом получении двуокиси марганца.This invention relates to electrochemical production, in particular to anodes used in the electrolytic production of manganese dioxide.

Известен электрод, содержащий титановую основу с нанесенной на нее активной массой из смеси окислов металлов платиновой группы и вентильных металлов и способ его изготовлени , заключающийс  в нанесении на основу компонентов по1фы и  с последующей термообработкой арл 200-8ОО С в окислительной атмосфере Ci}A known electrode containing a titanium base with an active mass deposited on it from a mixture of oxides of metals of the platinum group and valve metals and a method of its manufacture, consisting in applying the components of the base to the base and with the subsequent heat treatment of harles 200-8OO C in an oxidizing atmosphere.

Наиболее близким к изобретению по технической сущности и достигаемому результату  вл етс  способ изготовлени  анода, содержащего т гга овую основу и покрытие из смеси окислов металлов платиновой группы, согласно которому основу с нанесенными на нее компонетами покрыти  подвергают термообрабоо ке гфи 24О-110О С в вакууме в течение 15-вО мин C2iThe closest to the invention to the technical essence and the achieved result is a method of making an anode containing a thag base and a coating of a mixture of oxides of metals of the platinum group, according to which the base with coated components applied to it is subjected to heat treatment of vacuum 24O-110O C for 15-oO C2i min

Недостатком известных способов изготовлени  электрода  вл етс  их незначитальна  стойкость, потому что при ; равномерном удалении электролитической двуокиси марганца с пов хности анода отрываетс  и слой оксидного покрыти , что ведет к потере активности электрода .A disadvantage of the known methods of making an electrode is their insignificant resistance, because with; uniform removal of electrolytic manganese dioxide from the anode surface breaks down and the oxide coating layer, which leads to loss of electrode activity.

Целью изобретени   вл етс  повышение его стойкости.The aim of the invention is to increase its durability.

Поставленна  целЬ достигаетс  тем, что титановую основу с нанесенным на нее покрытием, содержащим золото, рутений , металлы платиновой группы юш The goal is achieved by the fact that the titanium base is coated with a coating containing gold, ruthenium, and metals of the platinum group

их смесь, подвергают термообработке в вакууме при 80О-1000 С в течение 3-5 ч.their mixture is heat treated under vacuum at 80 ° -1000 ° C for 3-5 hours.

При термообработке при указанных параметрах на поверхности анода образуетс  тонкий слой сплава, содержащего 1-2вес.% драгоценного металла и обладающий брльщой механической прочностью. При уменьщении времени прокалки не достигаетс  необходимое образование сло  сплава, при его увеличении свыше 5 ч наблюдаетс  значительна  диффузи  металлов покрыти  в титане, что ведет к потере электрокаталитических свойств.During heat treatment at the indicated parameters, a thin layer of an alloy containing 1-2% by weight of a precious metal and possessing excellent mechanical strength is formed on the surface of the anode. With a decrease in the calcination time, the necessary formation of an alloy layer is not achieved; with its increase over 5 hours, a significant diffusion of the coating metals in titanium is observed, which leads to a loss of electrocatalytic properties.

Пример. Титанова  основа известными способами очшцаетс  от жира, подвергаетс  пескоструйной обработке. Затем на ее поверхность наноситс  растве, содержащий компоненты покрыти После этого электрод сушитс  при 12О°С и подвергаетс  термообработке при давленииЮ - 10 бар. Указанна  операци  повтор етс  несколько раз дл  Получени  покрыти  необходимой толщины Изготовленные электроды используют дл  получени  электролитической двуокис марганца. Дикл электролиза гфрдолжает с  10 Д1ЮЙ. Дезактиваци  электрода в ходе повторных циклов с редел ет стойкость элек-фодов. Опытные данные представлены в таблице.Example. The titanium base is known from fat by means of known methods and is subjected to sandblasting. Then, a solution containing the components of the coating is applied to its surface. After that, the electrode is dried at 12 ° C and subjected to heat treatment at a pressure of 10 bar. This operation is repeated several times to obtain a coating of the required thickness. The fabricated electrodes are used to obtain electrolytic manganese dioxide. Dickle electrolysis unit continues from 10 Jun. 1. Deactivating the electrode during repeated cycles determines the resistance of the electrodes. Experimental data presented in the table.

Таким образом, как следует из 1Ц}едставленных данных, аноды изготовленные соШасно данному изобретению г имеют значительно больший ресурс работы, чем изготовленные известшм способом.Thus, as follows from the 1C} of the presented data, the anodes manufactured according to this invention have a significantly longer working life than those made by the known method.
