surbased detergent Explanation: Het aan het Engels ontleende 'overbased' lijkt in het Nederlands het meest gangbaar. Voorbeelden: “Er zijn 2 typen van metaalzouten, enerzijds de high “overbased” metaalzepen: deze hebben als functie het neutraliseren van het zuur. Anders de low “overbased” metaalzepen dienen als reinigingsmiddel. Enkele concrete voorbeelden van veelgebruikte detergenten zijn: - Sulfonaten - Fenaten - Salicatyen” (http://webcache.googleusercontent.com/search?q=cache:P6Le35T... “SWEPCO 123 Ultra EP Multi-Service Grease is een volledig nieuw vet, op basis van state-of-the-art overbased calcium sulfonaat chemie.” (http://swepcofromstratson.mamutweb.com/newsdet68.htm) “Unil pakt uit met Anderol FGCS-2, een overbased Calciumsulfonaat smeervet met uitzonderlijke uiterstedruk-eigenschappen, uitstekende mechanische stabiliteit en goede weerstand tegen oxidatie en corrosie.” (http://www.unil.be/_library/_files/121206_SERVLUB_NOV_12_NL_... Ter nadere interpretatie: “Overbased detergents, e.g., overbased alkaline metal or alkaline-earth metal compounds, are well known additives for lubricating oil compositions and petroleum fuels. These detergents perform a variety of functions including anti-corrosion, deposit control, acid scavenger functions and in general comprise overbased metal compounds complexed with an organic dispersant. For example, overbased magnesium compounds complexed with sulfonate and carboxylate dispersants, have long been used as anti-corrosion and acidic neutralization additives for lubricating oils and greases, anti-corrosion and acidic neutralization additives during the combustion of fuels such as residual fuel, pulverized sulfur-containing coal, corrosion inhibitors in fuels containing vanadium etc. The addition of overbased magnesium detergents to, for example, boiler fuels or gas turbine fuels, is known to reduce corrosion, presumably by forming magnesium complexes with the vanadium or sodium. Overbased metal detergents are also added to lubricating oils to prevent or remove deposits of oil-insoluble sludge, varnish, carbon and lead compounds which otherwise form on internal combustion engine parts and for combating severe rust conditions which may be encountered during shipping or storage of machinery or exposure to out-door weather. Detergent additives for automotive and diesel engine oils also react chemically with the highly acidic by-products of combustion that find their way into the lubricating oil system. Often, overbased metal additives are added as a dispersion in an appropriate carrier, in the case of lubricants and fuels, a high boiling liquid hydrocarbon is often used. Obviously the dispersion must be stable during storage and the overbased metal must stay well dispersed in the lubricant or fuel.” (http://webcache.googleusercontent.com/search?q=cache:K0hi_wz... |
