Detergent, английский
- In lubrication, either an additive or a compounded lubricant having the property of keeping insoluble matter in suspension thus preventing its deposition where it would be harmful. a detergent may also redisperse deposits already formed.
- Detergente
- A cleaning substance which removes grease and bacteria comment: most detergents are not allergenic but some biological detergents which contain enzymes to remove protein stains can cause dermatitis.
- A synthetic cleaning agent containing surfactants that do not precipitate in hard water and have the ability to emulsify oil and suspend dirt.
- One of several drilling fluid additives that reduces clay balling and keeps tooling clean.
- An additive which chemically neutralizes acidic contaminants in the oil before they become insoluble and fall out of the oil to form sludge. particles are kept finely divided so that they can remain dispersed throughout the lubricant.
Detergent (cleansers), английский
Detergents in cleansers are surface-active compounds that lower the surface tension of water or water solutions and impart emulsifying and dispersing properties to them.
Detergent (oils), английский
A metallic salt additive used in engine oils to keep insoluble particles in colloidal suspension and prevent the formation of deposits and rust. with dispersants, detergents also remove existing surface deposits.
Detergent oil, английский
Is a lubricating oil possessing special sludge-dispersing properties usually conferred on the oil by the incorporation of special additives. detergent oils hold formed sludge particles in suspension and thus promote cleanliness especially in internal-combustion engines. however detergent oils do not contain “detergents” such as those used for cleaning of laundry or dishes. also detergent oils do not clean already “dirty” engines, but rather keep in suspension the sludge that petroleum oil forms so that the engine remains cleaner for longer period. the formed sludge particles are either filtered out by oil filters or drained out when oil is changed.
Detergent remover, английский
See emulsifier, hydrophilic.
Dispersant, английский
- 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.
- An admixture which is capable of maintaining finely ground materials in suspension; used as a slurry thinner or grinding aid.
- A dispersing agent, often of a surface active chemical, that promotes formation of a dispersion or maintains a state of dispersion by preventing settling or aggregation.
- An additive that keeps insoluble contaminants dispersed (colloidally suspended) in a lubricant, preventing the particles from settling and accumulating. dispersants help prevent the buildup of sludge, varnish and other deposits.
- A non-metallic engine oil additive that helps to prevent sludge, varnish, etc., by keeping particles suspended in a colloidal state. similar to and ordinarily used with detergents, dispersants are capable of keeping large quantities of particles in suspension, and they are ashless when burned.
Dispersant (pt), английский
A substance for promoting the formation and stabilization of dispersed particles of one substance in another.
