Beschreibung
Zusammenfassung:	The invention relates to a composition for washing, depreservation and interoperational corrosion proofing and to a process for obtaining the same. The composition comprises 8.75 ... 18.75% by weight of refined naphthenic mineral oil , 0.15 ... 1.75% by weight of soap of fatty acids with 18 carbon atoms in the molecule and amphoter cation, 0.2 ... 1.2% by weight of esters of succinic acid, 0.01 ... 0.2% by weight complexing agent for copper, 0.6 ... 2.5% by weight non-ionic surfactants, 0.2 ... 1.2% by weight anionic surfactants, 75 ... 90% by weight solvating agent. The process for obtaining the composition consists in dispersing the fatty acid soap in refined naphthenic mineral oil, by heating the mixture at the temperature of 140 ... 150 C, cooling at 100 ... 110 C, dosing the additive package, then at the temperature of 60 ... 70 C dosing the non-ionic and anionic agents, dosing the solvating agent heated at 50 ... 60 C, continuing the homogenization for 2 hours. Invenţia se referă la o compoziţie pentru spălare, deconservare şi protecţie anticorosivă interoperaţională şi la un procedeu de obţinere a acesteia. Compoziţia este constituită din 8,75...18,75% g ulei mineral naftenic rafinat, 0,15...1,75% g săpun al acizilor graşi cu 18 atomi de carbon în moleculă şi cation amfoter, 0,2...1,2% g esteri ai acidului succinic, 0,01...0,2% g agent de complexare pentru cupru, 0,6...2,5% g agenţi neionici de suprafaţă, 0,2 ... 1,2 % g agenţi anionici de suprafaţă, 75...90% g agent de solvatare.Procedeul de obţinere a compoziţiei, constă în aceea că se dispersează săpunul acizilor graşi în ulei mineral naftenic rafinat, prin încălzirea amestecului până la temperatura de 140...150°C, răcirea la 100...110°C, dozarea pachetului de aditivi, apoi la temperatura de 60...70°C, dozarea agenţilor neionici şi anionici de suprafaţă, dozarea agentului de solvatare încălzit la 50...60°C, continuându-se omogenizarea, timp de 2 ore. ŕ
