THE ROLE OF BASE OIL BLEND AND THICKENER PERCENTAGE CHANGES ON THE BEHAVIOUR OF SOME PHYSICAL AND MECHANICAL PROPERTIES OF IRAQI BENTONITE GREASES

摘要

The behaviour of some physical and mechanical properties: viscosity, consistency, and water washout resistance (WWR), of greases prepared from Iraqi bentonite (IB) were studied with the percentage change of treated bentonite thickener and base oil blend (BOB). Viscosity, penetration degree, and WWR were measured according to the American Society for Testing and Materials (ASTM) standard.
