Aspects of Rheological Behavior of Rapeseed Oil
(Universitatea ”Dunărea de Jos” din Galați, 2009)This paper presents a study of dynamic viscosity variation with shear rate for rapeseed oils obtained from different stages of processing and the hydraulic oil grade H32. For each of the 6 types of oils studied was determined ... -
Ecological Lubricants Based on Vegetal Oils
(UDJG, 2011)Recently, there is an ecologically justified tendency to use lubricants based on vegetal oils and synthetic fluids, both ones reducing the application field of mineral oils. Biodegradable lubricants will be more used in ... -
Mechanical Resistance as a Function of Local Properties
(Universitatea "Dunărea de Jos" din Galați, 2007)The present study makes an estimation of an automotive engine piston mechanical properties and fatigue life based on some characteristics of metallurgical microstructure. Because it is intended to assess the properties ... -
On Viscosity Variation with Temperature of Rapeseed Oil After Different Processing Stages
(Universitatea ”Dunărea de Jos” din Galați, 2009)In recent years, vegetal oils are carefully studied as they may constitute a category of basic raw materials for obtaining organic biodegradable lubricants. Rapeseed oil is seen as an alternative of mineral and synthetic ... -
Vegetal Oils as Lubricating Materials
(Universitatea ”Dunărea de Jos” din Galați, 2008)The success of vegetal oils is related to their biodegradability and reduced toxicity but a wide use is limited by their insufficient stability in time. Biodegradable oils have ecological advantages, being comparable or ...
