The most commonly utilized emulsified fuel is a water-in-diesel emulsion (also known as hydrodiesel). [1] In these emulsions, the two phases are immiscible liquids—water and oil. Emulsified fuels can be categorized as either microemulsions or conventional emulsions (sometimes called macroemulsions to distinguish them from microemulsions).
By the 1990s, the Australian paint market was dominated by Wattyl, Taubmans and Dulux. [10] Until 1997, Dulux Australia was a key player in the ICI Paints World Group, after which ICI informed ICI Australia of its intention to sell its 62% share in the company as part of raising the capital needed for acquisition of part of Unilever.
A Ramsden emulsion, sometimes named Pickering emulsion, is an emulsion that is stabilized by solid particles (for example colloidal silica) which adsorb onto the interface between the water and oil phases. Typically, the emulsions are either water-in-oil or oil-in-water emulsions, but other more complex systems such as water-in-water, oil-in ...
A common type of degradation is the formation of tramp oil, also known as sump oil, which is unwanted oil that has mixed with cutting fluid. [17] It originates as lubrication oil that seeps out from the slideways and washes into the coolant mixture, as the protective film with which a steel supplier coats bar stock to prevent rusting, or as ...
The white gas sold today is a similar product but is produced at refineries and has a very low benzene content, benzene being a human carcinogen. [ 5 ] Though Coleman fuel has an octane rating of 50 to 55 and a flammability similar to gasoline, it has none of the additives found in modern gasoline .
Latex paints (emulsion paints British English, not to be confused with latex rubber) are an emulsion of polymer particles dispersed in water. Macroemulsions in latex paint are inherently unstable and phase separate, so surfactants are added to lower interfacial tension and stabilize polymer particles to prevent demulsification.
The water phase of oil-based mud can be freshwater, or a solution of sodium or calcium chloride. The external phase is oil and does not allow the water to contact the formation. The shales don't become water wet. Poor stability of the emulsion results in the two layers separating into two distinct layers. The advantages are: high drilling rates
usually range from approximately 10 nm to 100 μm; i.e., the droplets may exceed the usual size limits for colloidal particles. Note 4: An emulsion is termed an oil/water (o/w) emulsion if the dispersed phase is an organic material and the continuous phase is water or an aqueous solution and is termed water/oil (w/o) if the dispersed
