METHOD OF DETERMINING COLLOIDAL STABILITY OF GREASE AND DEVICE FOR REALISING SAID METHOD Russian patent published in 2010 - IPC G01N33/26 G01N33/30 

FIELD: chemistry.

SUBSTANCE: method of determining colloidal stability of grease is realised from the amount of oil squeezed from the grease, where a cup full of grease with a piston and fitted with an oiled filter together with a set of dry filters is subjected to thermal stabilisation and subsequently held under a load, after which the amount of oil squeezed from the grease into the dry filters is determined. Before thermal stabilisation, a medium boundary is created between the analysed grease and the dry filters by separating them from each other in order to prevent penetration of oil into the dry filters before loading. The amount of oil squeezed from the grease is determined from the displacement of the piston during loading. The invention also discloses a device for realising the said method.

EFFECT: more reliable determination.
