PROCEDIMENTO PER LA PRODUZIONE DI CARBON BLACK (NEROFUMO) PER PILE A SECCO

摘要

55Z2 DLT:lw 4/27/79 PROCESS FOR THE MANUFACTIJRE OF BATTERY CARBON BLACK Furnace carbon black process useful for the production of a carbon black used as an ingredient in dry cell battery compositions is disclosed which comprises heating a carbon black feedstock having a DPB ranging from 200 to 250 cc/l00g and a particle size distribution ranging from 55 to 130 millimicrons to a temperature ranging from 1400.degree.C to 2400.degree.C under an inert atmosphere, thereby producing a carbon black having a mean particle size distribution ranging from about 50 to about 120 millimicrons a dibutylphalate absorption (DBP) ranging from about 210 to about 270cc/l00g, a nitrogen surface area ranging from about 30 to about 60m2/g and an interplanar crystal lattice spacing (LC) ranging from about 2.7 to about 3.7 millimicrons.
