FIELD: process engineering.
SUBSTANCE: invention relates to production of black printing inks. Proposed method comprises production of carbon black by pyrolysis of hydrocarbon gas stock in mix with the products of combustion of hydrocarbon fuel gas and air combusted in combustion chamber at air excess factor ≈0.7-0.9, tempering of pyrolysis products by demineralised water, cooling in heat exchange and carbon black separation. Produced carbon black is mixed with thin mineral oil to reach 8-10 sPs Larey viscosity of suspension. Ink fluid components are mixed with carbon black suspension. Produced mix is subjected to cavitation in hyper turbulent flow for homogenisation in closed space of straight-flow hydrodynamic cavitator to Larey viscosity of 3-4 sPs.
EFFECT: simplified and intensified process, higher quality of ink, lower power input.
