A chemical added to a liquid to lower its freezing point. Ethylene glycol, a form of alcohol, is an antifreeze agent that is normally used as the coolant in liquid-cooled reciprocating engines.
Industry:Aviation
A chemical added to an engine lubricating oil to alter its basic characteristics.
Additives are used to prevent foaming, improve viscosity index, and increase corrosion inhibiting properties.
Industry:Aviation
A chemical added to turbine-engine fuel used in some aircraft. This additive mixes with water that condenses from the fuel and lowers its freezing temperature so it will not freeze and block the fuel filters. It also acts as a biocidal agent and prevents the formation of microbial contamination in the tanks.
Industry:Aviation
A chemical cleaner used to loosen dirt, grease, oxides, and carbon deposits from the surface of an aircraft. Solvents are mixed with water and a petroleum product, such as naphtha. An emulsifying agent is used to form an emulsion with these products that do not normally mix.
The cleaner is sprayed on the dirty surface and allowed to remain long enough to penetrate the surface contamination and reach the metal. Then it is washed off with hot water or steam.
Industry:Aviation
A chemical compound added to a liquid to lower its freezing temperature. FPDs are used in the fluid sprayed on an aircraft to deice it before flight.
Industry:Aviation
A chemical compound consisting of a metal, usually a base, or a non-metal, usually an acid, and a negative hydroxyl ion (OH). Hydroxides are found in both organic and inorganic chemicals. Some of the more familiar hydroxides are sodium hydroxide (NaOH) and potassium hydroxide (KOH).
Industry:Aviation
A chemical compound of carbon and a metallic element. Carbides are normally very hard materials.
Industry:Aviation
A chemical compound such as toluene, xylene, and benzene that is blended with gasoline to improve its antidetonation characteristics.
Aromatic compounds have the bad feature of softening rubber hoses, diaphragms, and seals used in fuel metering system components.
