Oil IGP-72 (TU 38.101413-97) is a distillate, residual oil or a mix of distillate and residual oils from sulphurous petroleums of deep selective clearing with antioxidizing, antiwear, anticorrosive and antifoamy additives.
Apply them basically to greasing of the modern domestic and import equipment in various branches of a national economy for which operation oils with the improved operational properties are necessary.
Oil IGP-72 use in hydraulic systems heavy прессового the equipment and for greasing шестеренчатых transfers, middlingloaded gear and worm reducers, in circulating systems of grease of the various equipment.
The basic indicators characterising operational properties of oils IGP, viscosity, stability against oxidation, anticorrosive properties and firmness to foaming are.
Viscosity kinematic, cSt, at 40°С, not less: 110-125
Mass fraction of zinc, %, not less: 0.04
Mass fraction of sulphur, %, not less: 1
Flash temperature, in an open crucible, °C, not more low: 220
Hardening temperature, °C, not above:-15
Data on operational temperatures represent values which are guided by a structure of lubricants, and also on a scope and technology of use. Depending on a kind of mehaniko-dynamic loading lubricants change the consistence, conditional viscosity or viscosity at various temperatures, pressure and duration of operation. These changes of indicators can affect work of components.
