Lubricating Oil Additives
1.1 Lubrication (Rizvi, 2009) The principle of supporting a sliding load on a friction reducing film is known as lubrication (Ludema, 1996). The substance of which the film is composed is a lubricant, and to apply it is to lubricate. These are not new concepts, nor, in their essence, particularly involved ones. Farmers lubricated the axles of their ox carts with animal fat centuries ago. But mo...
متن کاملLubricating gears with synthetic OiLs
wind gearbOx technOLOgy is developing at a fast pace, not least due to operators demanding ever more power and efficiency. Experience has shown that the lubricant used is a crucial factor in meeting the wish for ever-increasing performance. Besides strictly technical requirements, aspects of economy and ecology are receiving more and more attention in lubricant selection. The technical requirem...

The Re-refining of Used Lubricating Oils
Re-refined lubricants have been produced in New Zealand for over 50 years. However, their acceptance as a high quality lubricant has been a gradual process, largely because of the scepticism of the public that the product can be re-refined to its original condition. In New Zealand Dominion Oil rerefines about 7 million litres per year, while an older acid clay method is used at Turua near Thame...
متن کاملFeasibility of Polysulfone as Base Polymer in a Polymer Inclusion Membrane: Synthesis and Characterisation
Polysulfone was investigated as an alternative base-polymer for polymer inclusion membranes (PIM’s) that could withstand harsh environmental conditions and have good transport efficiency of metal ions. PIM’s were prepared using polysulfone as a base polymer and Aliquat 336 as a carrier in the absence of a plasticizer. Chromium (VI) was used as standard to study the extraction efficiency of the ...
