| Description |
The biodegradability of metalworking fluids has assumed very high priority. Biodegradable metalworking fluid
formulations consist of vegetable oil, an emulsifier, co-surfactant, fungicide and additives. Non-edible vegetable
oils such as neem, ricebran, and karanja oil are renewable, biodegradable and cheaper than synthetic fluids. Oleates
and fatty-acid amides of these oils have been used as emulsifiers to eliminate biohard emulsifiers. Additives are
used to achieve a high level of performance. Metalworking soluble oil formulations were evaluated for physicochemical
characteristics such as emulsion and thermal stability, copper-strip corrosion, iron chip corrosion,
deposit-forming tendency on hot metal surfaces, and lubricity. Oil–water micro-emulsions of these oils have
higher stability. The emulsions were stable over a wide range of temperatures. Performance of formulations from
all three oils are found at par with the ASTM specifications. Neem oil based formulation showed better characteristics
than ricebran and karanja oil. Copyright © 2006 John Wiley & Sons, Ltd.
