Viscosity and Wetting Properties of Pitch

Resumo

The viscosity, wetting properties, and fluidity threshold of coal and other pitches are considered. The fluidity threshold of coal pitch is determined, and the influence of heat treatment on this temperature is studied. The softening temperature and fluidity threshold of the pitch samples are compared. The relation between the viscosity of pitch and its composition, wetting properties, and mass loss on heating to 360°C is analyzed.
