What Does Dispersant Mean?
A dispersant is either a non-surface active compound or an active substance added to a suspension, usually a mix, to increase the separation of particles and to prevent subsiding or clumping. Dispersants may consist of one or many surfactants, but may also be gases.
Dispersants are primarily utilized in petroleum and heavy duty diesel oils. They are also utilized in engine oils, aviation fuels and many gear lubricants, as well as concrete and detergents.
Dispersants are also known as dispersing agents, softeners, plasticizers or super-plasticizers.
Corrosionpedia Explains Dispersant
Dispersants are lubricator additives that help to prevent sludge, varnish and other deposits from forming on surfaces. Dispersing agents are added to lubricating oils utilized in automotive engines to inhibit the buildup of varnish-like deposits on the cylinder walls and to gas to prevent the buildup of residues. Dispersants are essential additives in engine oils to keep engine elements clean. They perform both in aqueous and non-aqueous environments.
Dispersants are also utilized in concrete blends to lower the utilization of water and maintain constant slump (flow) property. This makes the concrete stronger and more resistant to water penetration.
Dispersants in oil drilling aid in breaking apart solids or liquids as fine particles or droplets. An oil dispersant may be a mixture of surfactants and associated solvents that help break oil into tiny droplets following an oil spill.
