How does the mineral filled method affect viscosity, breaking behavior, and storage stability of bitumen emulsions?
Mineral fillers increase viscosity and can improve film build and skid resistance, but they also raise risk of settling and nozzle clogging. Fillers accelerate breaking by providing nucleation sites, which must be controlled through emulsifier choice and dosage. Storage stability depends on particle size distribution and agitation. Plants must handle higher shear and provide effective mixing to avoid segregation.
