Description

в насто щее врем  примен ютс  два основных способа получени  диснерсного кадмиевого препарата дл  изготовлени  активной массы отрицательного электрода щелочного аккумул тора .At present, there are two main methods used to obtain a disneric cadmium preparation for the manufacture of the active mass of the negative electrode of an alkaline battery.

Наибольшее промыщленное распространение имеет электролитический способ получени  дисперсного кадмиевого препарата, при котором диспергирование кадми  производитс  путем электролиза при повышенной катодной плотности тока. Кроме того, известен химический способ получени  кадмиевого препарата, при котором дисперсный кадмиевый препарат получаетс  путем осаждени  щелочью из раствора соли.The electrolytic method of obtaining a dispersed cadmium preparation has the highest industrial distribution, in which cadmium dispersion is carried out by electrolysis at an increased cathodic current density. In addition, a chemical method is known for the preparation of a cadmium preparation, in which a dispersed cadmium preparation is obtained by precipitation with alkali from a salt solution.

Электролитический способ получени  препарата имеет р д существениых трудностей-сложность электролиза и дальнейшей обработки губки, недостаточна  однородность получаемых препаратов, применение больших количеств вспомогательных материалов (вода и кислота).The electrolytic method of obtaining the drug has a number of significant difficulties — the complexity of the electrolysis and further processing of the sponge, the uniformity of the preparations obtained, the use of large quantities of auxiliary materials (water and acid).

Недостатками химического способаThe disadvantages of the chemical method

получени  препарата  вл ютс  неизбежные потери препарата при отмывке и прессовке, большое число операций , через которые проходит препарат , применение больших количеств вспомогательных материалов (вода, соли, щелочи).preparation of the drug are the inevitable loss of the drug during washing and pressing, a large number of operations through which the drug passes, the use of large quantities of auxiliary materials (water, salt, alkali).

Этих недостатков не имеет предлагаемый способ получени  дисперсного препарата кадми  путем возгонки расплавленного металла. В зависимости от среды, в которой происходит конденсаци  паров, могут быть получены препараты различной металличности. Электрические испытани  опытных образцов показали, что получаемый при окислении паров кадми  в токе кислорода или воздуха препарат имеет нормальное (дл  электродов из кадми  без экспандирующих добавок) использование кадми , равное 40-459 от теоретического, и может быть применен после смешени  с отдельно приготовленными добавками в качестве активной массы отрицательного электрода щелочного аккумул тора .The proposed method for preparing the dispersed cadmium preparation by sublimation of the molten metal does not have these disadvantages. Depending on the environment in which vapor condensation occurs, preparations of various metallicities can be obtained. Electrical tests of prototypes showed that the product obtained by cadmium oxidation in a stream of oxygen or air has a normal (for cadmium electrodes without expansion additives) use of cadmium equal to 40-459 from theoretical, and can be applied after mixing with separately prepared additives as the active mass of the negative electrode of an alkaline battery.
