INHIBITEUR DECAPAGE [3 records]

Record 1 2009-09-25

English

Subject field(s)
  • Metallurgy - General
CONT

Pickling inhibitors are interfacially active organic or inorganic substances. As a result of electrostatic interactions, they cover the iron surface with a monomolecular layer and thus reduce the pickling attack.

French

Domaine(s)
  • Métallurgie générale
CONT

L'utilisateur sera amené à faire un compromis lors du choix de l'inhibiteur de décapage entre une grande efficacité inhibitrice lors du traitement et une désorption facile après décapage. En effet, l'adsorption d’un inhibiteur de décapage doit être facilement réversible et ne doit pas se révéler pénalisante pour d’autres réactions effectuées en milieu acide(cas de la phosphatation par exemple).

CONT

As a result of the larger diameter Vanguard satellite design, the original Aerobee was now too skinny for use as a second stage. A new larger-diameter stage designed by Aerojet-General would have to be used instead. It incorporated an AJ-10 rocket engine that developed 33 kilonewtons (7,500 pounds) of thrust using the storable propellants inhibited white fuming nitric acid and symmetrical dimethyl hydrazine.

CONT

I have developed several liquid rocket engines using both cryogenic and storable propellants. We have never had a problem with cryogenic propellants (and yes we have never had a LOX valve freeze -- you have to use the proper valve). We have shifted over to storable propellants (Inhibited White Fuming Nitric Acid and furfuryl alcohol) because of their high density, hypergolicity, and long term storage capability.

OBS

inhibitor: Substance, naturally occurring or a synthetic additive, whose presence in small amounts in a petroleum product retards or prevents the occurrence of certain phenomena considered undesirable, e.g. gum formation in stored gasolines, corrosion in steam turbines. [Definition standardized by ISO.]

CONT

Dowtherm and Dowfrost antifreeze is specially designed for process chiller systems. All chilled water systems can benefit from any of Dow's specially inhibited ethylene glycol and propylene glycol based solutions. ... Dowtherm SR-1 inhibited ethylene glycol-based fluid. With an operating temperature range of -60°F to 250°F, this is the most widely used fluid for heating and HVAC applications. The specially formulated corrosion inhibitor package is easily maintained, long-lasting and replenishable.

CONT

coolant: Sometimes called anti-freeze, this is a solution of inhibited ethylene glycol or inhibited propylene glycol plus water that circulates through the system to keep the engine cool. It's also a rust and corrosion inhibitor. Ethylene glycol or propylene glycol is only the anti-freeze part. The corrosion inhibitor is a chemical additive typically TT (tolytriazole) or nitrites as sodium nitrite.

CONT

Antifreeze, Inhibited Ethylene Glycol. Ethylene glycol is used for freeze protection of the coolant. IEG, commonly referred to as "antifreeze," also contains chemicals that provide a limited pretection against corrosion. The use of an IEG product with a low silicate formulation that meets ASTM D 3306 or GM 6043M requirements is recommended.

OBS

inhibitor: Substance, naturally occurring or a synthetic additive, whose presence in small amounts in a petroleum product retards or prevents the occurrence of certain phenomena considered undesirable, e.g. gum formation in stored gasolines, corrosion in steam turbines. [Definition standardized by ISO.]

OBS

IEG: This might be an in-house or a non-recognized abbreviation; not to be used alone, to avoid any risk of confusion.

Détartrant désincrustant pour lave-vaisselle industriel. Applications. Produit destiné au détartrage et à la désincrustation des lave-vaisselle industriels, matériels divers, assiettes, plateaux, verres, etc,... Description. Aspect : liquide limpide rose. Nature : acide fort additionné d’un inhibiteur de corrosion.

OBS

La galvanisation à chaud. [...] avant l'immersion dans le bain de zinc, les pièces à galvaniser passent [par le] décapage, [qui] se fait à l'aide d’acide chlorhydrique additionné d’un inhibiteur(3 à 6 mol/l) et permet d’éliminer la calamine et certains autres oxydes présents en surface.

OBS

Le Décalaminox 4A est un décapant acide inhibé spécialement conçu pour éliminer les différents oxydes, sans attaque du métal ainsi que les sables vitrifiés résiduels de fonderie.
