Определение dispersant в Английский Язык Английский Язык словарь
Any substance that is used to to prevent settling or clumping of particles suspended in a liquid
In aromatherapy, a non-alcoholic agent or surfactant that is used to distribute or dissolve essential oils evenly into the surface of water See also Bath Base
Chemical that causes insoluble ingredients to be evenly distributed throughout a liquid
A chemical agent used to break up concentrations of organic material such as spilled oil
engine oil additive that helps prevent sludge, varnish, and other engine deposits by keeping particles suspended in a colloidal state Dispersants are normally used in conjunction with detergents A dispersant is commonly distinguished from a detergent in that the former is non-metallic and, thus, does not leave an ash when the oil is burned; hence, the term ashless dispersant Also, a dispersant can keep appreciable larger quantities of contaminants in suspension than a detergent
{i} mixture which disperses, something which sends in different directions (Chemistry)
Any substance that is used to stabilize a dispersion or suspension of particles in a liquid
an oil additive that keeps fine particles of insoluble materials in a homogeneous solution, preventing settling out and accumulating on a surface
Something that disperses A chemical substance added to a dispersion capable of maintaining the dispersed particles in suspension
In lubrication, a term usually used interchangeably with detergent An additive, usually nonmetallic ("ashless"), which keeps fine particles of insoluble materials in a homogeneous solution Hence, particles are not permitted to settle out and accumulate
lubricating oil additive Usually organic polymer containing nitrogen groups that help control sludge, varnish, and otter engine deposits by keeping deposit precursors finely dispersed in the oil so that they cannot form oil insoluble materials that can settle out of the oil Dispersants are usually used in conjunction with detergents
Dispersants are similar to detergents in that they too are cleanliness agents Chemically, they are different They function like repelling magnets and keep solid particulate (up to 3 microns) contamination and chemical compounds from agglomerating into deposits such as sludge or varnish When either the detergent or dispersant become depleted or "worn out", you will then get sludge or deposits in the engine NOTE: TBN (Total Base Number) is a numerical combination of these two additives (see the TBN section for more details)
