Definitions

  • the present invention relates to a functional fluid corrosion inhibitor, a water-miscible water-based functional fluid-containing concentrate containing this corrosion inhibitor, and the use thereof.
  • HFA fluids are liquids used as lubricants, abrasives, coolants and lubricants for metal forming and metal cutting, and more particularly as hydraulic fluids, namely, hydraulic fluids.
  • These water-based functional fluids are also referred to as HFA fluids or HFA hydraulic fluids.
  • HFA hydraulic fluids are used in particular in the hydraulic longwall mining systems. They are prepared on site by mixing from 1 to 20% by weight of a water-miscible concentrate containing the necessary active ingredients with correspondingly 99 to 80% by weight of water. The concentrates may contain as lubricants, synthetic products or those based on mineral oil.
  • the HFA hydraulic fluid obtained is either an emulsion (HFAE), including a microemulsion, with mineral or synthetic oil, or solutions (HFAS).
  • HFAE emulsion
  • HFAS HFAS
  • Such HFA hydraulic fluids have the viscosity of water and can be used in a temperature range of + 5 ° C to + 55 ° C.
