Abstract
Inventia se refera la un procedeu de obtinere a unui aditiv pentru paste de cimentare, prin amestecarea unei solutii de NaOH cu reziduuri de tartrati cu continuturi de 34% substante solubile si 66% substante insolubile, în raport în greutate de 100:38, la temperatura de 90 degree C, adaugarea lignosulfonatului de amoniu sau calciu la aceeasi temperatura, iar dupa racirea amestecului obtinut în final, adaugarea unui antispumant pe baza de motorina si octanol, substante tensioactive uzuale si formaldehida.The invention relates to a process for obtaining a cement paste additive by mixing a solution of NaOH with tartrate residues containing 34% soluble substances and 66% insoluble substances in a weight ratio of 100:38 at a temperature of 90 ° C, the addition of ammonium or calcium lignosulfonate at the same temperature and, after cooling the mixture finally obtained, the addition of an anti-sparking agent based on diesel and octanol, common surfactants and formaldehyde.
