Natural gas semi-reinforcing north tower torch, carbon black N772 iodine absorption value 18 oil absorption value 45

Overview

Semi-reinforcing furnace black by gas-furnace process (SRF-G) is a kind of carbon black produced by partial combustion and pyrolysis in 1250 ~ 1350 ° C reactor with natural gas as raw material and certain proportion of air. It is the main kind of semi-reinforced carbon black. Also known as natural gas semi-reinforcing furnace black. The particle size is 80-130 nm, oil absorption value is 0.40-0.70 ml/g, iodine absorption value is 10-25 mg/g. It is characterized by large particle size range and low structure.
