摘要

Smoke black, production method of smoke black, and device for implementing the method. The present invention relates to a smoke black having a size distribution of aggregates, which have a reason (d ~ 90 ~ d ~ 10 ~ d ~ 50 ~ less than or equal to 1.1.Carbon black is produced by mixing hot air, if desired, a gas mixture comprising a carrier gas and a load feeding of smoke black, passage of the gaseous mixture to a tube burner, burning of the gas mixture in the openings of the tube burner, and withdrawal of the S flames under suction, along with ambient air captured freely under suction from the outside.For a will in narrowing, cold, and conduction cooling, are narrowing, cold and a ratio of height (H) to the width (b) of 1 - 100, the width (b) is from 0.5 to 10 mm, and the flow rate at the narrowest point of being 10 to 200 m / s, carbon black of the invention can M to be used as a load of no reinforcement, a booster charge, a UV stabilizer, a black driver.A pigment or a reducing agent.
