Description
Известна активна масса электродов свинцово-кислотных аккумул торов, приготовленна из свинцового порошка или .свинцовых окислов и серной кислоты. Недостатком аккумул торов с такими электродами вл етс сильное газовыделение so врем зар да, создающее опасность образовани взрывчатой смеси, что приводит .к необходимости испльзовани дополнительных вентил ционных систем либо газоиоглотительных или окислительных агрегатов.The active mass of lead-acid battery electrodes, prepared from lead powder or lead oxides and sulfuric acid, is known. A disadvantage of batteries with such electrodes is a strong gassing, so the charging time creates a danger of forming an explosive mixture, which leads to the need for additional ventilation systems or gas absorption or oxidizing units.
С целью уменьшени газовыделени предлагаетс IB качестве добавки в активную массу электродов примен ть фторопласт 4Д в количест1ве 0,3 - 5,00/0Фторопласт 4Д .представл ет собой модификацию политетрафторэтилена. Это порошкообразное кислотостойкое поверхностно-активное вещество. Фторопласт ввод т в активную массу в процессе ее изготовлени перед заливкой серной кислоты.In order to reduce gas evolution, it is proposed IB as an additive to the active mass of the electrodes to use fluoroplastic 4D in the amount of 0.3 - 5.00 / 0 Fluoroplastic 4D. This is a modification of polytetrafluoroethylene. It is a powdered acid resistant surfactant. Fluoroplastic is introduced into the active mass in the process of its manufacture before pouring sulfuric acid.
В качестве поверхностно-активной добавки может бытьтакл е использован фторопласт45.Fluoroplastic 45 can be used as a surfactant additive.
