Description

  . . -J -. ; The invention relates to the field of formulation of working fluids, applied in hydraulic systems operating under conditions of high fire. hazards (metallurgichesk. kre. production-; nstvo, mining / industry, shipboard girssistfmy). ,

A water-based hydraulic fluid with the addition of corrosion inhibitors and vinyl merrolidone supplement is known. It may also contain various lycol, a defoamer, an antifoam agent, etc.

This fluid is flame retardant / flame retardant and has good load carrying capacity and compatibility with various rubbers as well. good in viscous-temperature "characterization. . .,. - -.
