How does stabilisation chemistry affect storage life and transport of bitumen emulsions?

[David]

Stabilization chemistry controls droplet charge and the strength of repulsive forces between droplets. If the pH drifts or ionic strength increases during transport, repulsion weakens and droplets can coalesce, leading to creaming, sedimentation, or partial breaking. Temperature swings also change viscosity and can accelerate separation. A robust stabilized emulsion maintains droplet size distribution over time and tolerates reasonable agitation without breaking. For transport, this means fewer rejects, longer allowable storage, and safer pumping at destination. Buyers should specify storage stability limits and require sampling after transport conditions similar to their real logistics route.
