Abstract

Inventia se refera la un electrod-placa negativ pentru acumulatoare acide cu plumb, pentru pornire, cu capacitate de scadere rapida la temperatura scazuta îmbunatatita si durata de viata marita. Electrodul comform inventiei este prevazut cu masa activa, sub forma de pasta, în care s-au introdus: fibre de sticla, în locul fulgilor Dynel, cu rol de fibre de armare si fibre "canal"; bioxid de siliciu amorf, în scopul cresterii rezervei de electrolit din masa activa; carboximetilceluloza, care în prezenta electrolitului se gelifiaza si preia tensiunile create în electrod datorita modificarilor de volum. Electrozii, conform inventiei, prezinta avantajul unor capacitati de scadere rapida la temperatura scazuta si fiabilitate în exploatare marita. De asemenea se obtine o prelungire a duratei de viata.The invention relates to a lead-acid lead-acid-negative lead electrode for start-ups, having a rapid lowering capability at improved low temperature and increased lifetime. The electrode according to the invention is provided with an active paste form in which glass fibers are introduced instead of Dynel flakes as reinforcing fibers and "channel" fibers; amorphous silicon dioxide for the purpose of increasing the electrolyte reservoir of the active mass; carboxymethylcellulose, which, in the presence of the electrolyte, gelifies and absorbs the voltages created in the electrode due to volume changes. The electrodes according to the invention have the advantage of low low temperature lowering capabilities and increased operating reliability. It also provides a prolonged lifetime.
