Abstract
Procedeu de obtinere a negrului de fum, caracterizat prin aceea ca un amestec pe baza de polimeri constituit din deseuri de cauciuc vulcanizat singur sau în amestec cu pîna la 70% deseuri de materiale plastice si rasini sintetice si pîna la 50% reziduuri de la cocsificarea carbunilor, rafinarea titeiului si din industria petrochimica, se supune descompunerii termice la temperaturi cuprinse între 250 si 950 degree C, apoi se supun produsele volatile rectificarii la temperaturi cuprinse între 400 si 900 degree C si separarii fractiunilor si extractelor.
