Definitions
- the invention relates to an environmentally compatible grease for steel cables, in particular galvanized steel cables.
- the invention further relates to a method for producing the grease and its use.
- Lubricants for steel cables are used to separate the individual rope strands from each other by a lubricating film, i. H. to lubricate and thereby reduce wear, as well as to protect the steel cable as a whole against corrosion.
- a lubricating film i. H. to lubricate and thereby reduce wear, as well as to protect the steel cable as a whole against corrosion.
- the lubricants In the field of application, the lubricants must also perform various additional tasks. For example, in the marine industry and in the oil and gas industry, it is necessary that the lubricants not only have a good lubricating effect, but can also be used in a wide temperature range and in the presence of water. Are galvanized
