Determination of low-temperature properties of lubricating greases

Abstract

The article presents the results of laboratory tests of low-temperature properties of lithium complex greases produced on base oils, characterized by a different chemical structure. Low-temperature properties of lubricating greases were determined according to the following test methods: • low-temperature cone penetration-PN-ISO 13737, • flow pressure-DIN 51805-2, • apparent viscosity-PN-C-04146. It was found that the low-temperature properties of lubricating greases can be modified by introducing oils with a different chemical structure into the oil base. The lowest temperature of application of the tested lithium complex greases was determined.
