They contain in particular saturated ones Hydrocarbons.
Synthetische Mineralöle sind Öle, welche aus geeigneten Ausgangsstoffen oder durch chemische Modifizierung von natürlichen Mineralölen hergestellt werden. Die Schmiermittel sind im Allgemeinen unter den Anwendungsbedingungen (Druck, Temperatur) flüssig. Vorzugsweise sind sie bei 21°C, 1 bar flüssig.Synthetic mineral oils are oils made from suitable raw materials or by chemical modification of natural mineral oils. The lubricants are generally under the conditions of use (pressure, temperature) liquid. Preferably, they are liquid at 21 ° C, 1 bar.
Unterschieden wird zwischen nicht wässrigen und wässrigen Schmiermittel. Im Rahmen dieser Erfindung sind wässrige Schmiermittel bevorzugt.differences is used between non-aqueous and aqueous lubricants. In the context of this invention are aqueous lubricants prefers.
Bei den wässrigen Schmiermitteln kann es sich um wässrige Lösungen von entsprechend polaren Mineralölen, z. B. synthetischen, polymeren Alkoholen, handeln.at The aqueous lubricants may be aqueous Solutions of correspondingly polar mineral oils, z. As synthetic, polymeric alcohols act.
