| titleOfInvention | Postemulsifiable dye penetrant system and method for using same |
| abstract | Postemulsifiable dye penetrant inspection system and method employing substantially biodegradable dye penetrant compositions and emulsifiers, for use in non-destructive testing of objects to locate voids and defects therein, the dye penetrant composition consisting essentially of an organic dye, preferably a fluorescent dye, and a carrier or solvent for said dye, in the form of certain straight chain, primary, aliphatic oxyalkylated alcohols, particularly biodegradable surfactants comprised of the nonionic condensation products of linear primary aliphatic alcohols having from 10 to 18 carbon atoms, with ethylene oxide and propylene oxide, preferably in the form of a mixture thereof, or in the form of certain ethoxylated secondary alcohols, particularly the biodegradable nonionic surfactants comprised of ethoxylates of a mixture of secondary alcohols having linear alkyl chains of from 11 to 15 carbon atoms, such surfactants and the resultant dye penetrants having limited water solubility and normally requiring large amounts of water at high pressure for removal of excess dye penetrant from the object surface. An emulsifier is thus employed to treat the penetrant covered object surface and to remove excess dye penetrant, such emulsifier also comprised of the above noted classes of biodegradable nonionic surfactants, but of a composition or nature which are highly soluble and which facilitate removal of the resulting emulsified dye penetrant with water as by spraying. |
