Zusammenfassung: | agents for protection of hydrophilic liquids from evaporation, saturation with gases, mechanical contaminants from atmosphere and protection reservoir equipment from corrosion. SUBSTANCE: sealing liquid comprises, wt %; high molecular polyisobutylene, 2.5-3.3; indene-coumarone resin, 0.8-1.1; anhioxidant which is formaldehyde-orthotertbutylparacresol condensation product, 0.05-0.14; ceresin wax, product of petrolatums from deparaffinization of residual petroleum raffinates, 0.93-0.95; 4-methyl-2,6-ditertiary butylphenol, 0.3-0.5; product of modifying sunflower oil with diethanolamine-boric acid condensate, 0.3-0.5; and industrial petroleum oil, up to 100.00. Sealing liquid is physiologically harmless, has increased protective and thermally stable properties. Layer has thickness of 1.0-2.0 mm depending on application conditions. EFFECT: improved properties of the sealing liquid. 3 tbl |
