Abstract
Inventia se refera la un electrolit pentru obtonerea de straturi acoperitoare de staniu, lucioase, care pot fi utilizate în radiotehnica si electronica, la productia de aparate pentru montajul autovehiculelor, în industria produselor alimentare si farmaceutice. în descriere se indica compozitia baii de electroliza conform inventiei, care are ca efect straturi acoperitoare cu un luciu bine echilibrat (82% fata de 100% a oglinzii de argint) si elimina deficientele bailor de electroliza cunoscute din stadiul tehnici. Electrolitul conform inventiei contine 100....180 g/l acid sulfuric, 20....60 g/l sulfat de staniu, 4 ml/l formol de 38%, 0,2....0,8 g/l benziliden-acetona în calitate de agent de luciu, un agent tensioactiv cu formula generala CnH2nYO (CH2CH2O)mX, în care Y = hidrogen sau un radical aril, X = hidrogen, SO2H sau SO3H; n este un coeficient numeric cuprins înte 8 si 18, m = 4....25, cu o concentratie de 3 pîna la 14 g/l si 0,05......0,8 g/l dintr-un derivat al acidului nicotinic cu formula (vezi formula) în care X = OH, NH2 = =(CH2CH2O)qH, 0 NH(CH2CH2O)pH,Q respectiv p fiind coeficienti mnumerici întregi a caror valoare este cuprinsa între 1 si 4.
