- To 24 hours storage at + 3 ° C, the oil is tested according to the conditions of the British Rail filtered and the lubricating effect on the filtrate determined in the HFRR test.
- the High Frequency Reciprocating Rig Test (HFRR) is described in D. Wei, H. Spikes, Wear, Vol. 111, No. 2, p. 217, 1986 and is carried out at 60 ° C.
- the Results are as a coefficient of friction (Friction) and Wear Scar (WSD) specified. Show a low coefficient of friction and a lower wear scar a good lubricating effect.
- the polymers were 50% in kerosene set.
- the viscosity was determined using a rotary viscometer (Haake RV 20) with plate-cone measuring system at 140 ° C, in accordance with ISO 3219 (B).
- the additives according to the invention for use as a flow improver and / or lubricity additive, the additives according to the invention furthermore in a mixture with paraffin dispersants be used.
- the employed Wachsdispergator (F) is a mixture of 2 parts of a terpolymer of C 14/16 - ⁇ -olefin, maleic anhydride and 2 equivalents of di-tallow Allylpolyglykol with and a part of nonylphenol-formaldehyde resin.
- the cold flow improver polymers mentioned and, if appropriate, in addition the wax dispersant mentioned were mixed with the amphiphiles mentioned.
