Dispersant - Wikipedia
网页A dispersant or a dispersing agent is a substance, typically a surfactant, that is added to a suspension of solid or liquid particles in a liquid (such as a colloid or emulsion) to improve the separation of the particles and to prevent their settling or clumping. [1]

网页2023年11月3日 · Dispersants, also called dispersing agents, are chemical agents used to break up oil into smaller droplets in the water column. Dispersants can be applied on surface oil or below the surface, closer to an uncontrolled …
Dispersant - an overview | ScienceDirect Topics
网页Dispersants are substances that disperse another substance in a medium such as water to form a colloidal solution. Their main function is to reduce the adhesion between particles and prevent flocculation or agglomeration. Dispersants are generally divided into two categories: inorganic dispersants and organic dispersants.
Comprehensive Guide to Dispersants and Dispersing Agents for …
网页Dispersants, also named dispersing agents, are essentials ingredients in the formulator’s toolbox. They help keep pigments and fillers stable until the application of the paint, and the formation of the dried coating. Beyond bright and vivid colors, many other coating properties depend on the choice of your dispersants.
5. How Do Dispersants Work? | response.restoration.noaa.gov
网页2012年5月29日 · Dispersants work much like the detergent soap that you use to clean grease from your dishes (but dispersants are less toxic). They contain molecules with a water-compatible ("hydrophilic") end and an oil-compatible ("lipophilic") end. These molecules attach to the oil, reducing the interfacial tension between oil …
Dispersing Agents: Learn The Basics In 3 Simple Steps
网页2024年1月18日 · Dispersants are substances or chemicals that are used to improve the dispersion or uniform distribution of particles in a medium, typically a liquid. The primary goal of dispersants is to prevent agglomeration or clumping of particles, enabling them to remain stably dispersed throughout the medium.

网页2010年5月12日 · What do dispersants do? Dispersants do not remove oil from the area. Rather, they help large globs of oil 'disperse' into smaller pieces — hence their name — which are easier for sea-living...
网页Dispersants remove oil from the water surface thereby protecting birds, mammals, and sensitive shorelines. Dispersants can be used under a broad range of environmental conditions. For large offshore spills, the limitations of other response options may make dispersants the most effective response tool. Modern dispersants are biodegradable and

网页A dispersant is an additive that helps prevent contaminants in oil from precipitating out of the oil and depositing on engine surfaces. Generalized Structure and Function. A generalized structure of a dispersant is shown in Fig. 1. The hydrocarbon tail is needed to help solubilize the dispersant and contaminant particles in oil.
