TRIBOLOGICAL PROPERTIES OF BLACKBERRY WASTE SEED EXTRACT OBTAINED UNDER SUPERCRITICAL CO2 CONDITIONS WITH SORBITAN ESTERS COMPOSITONS
Journal Title: Tribologia - Year 2018, Vol 278, Issue 2
Abstract
This paper presents results of tribological research of a composition containing as a base, extract of waste blackberry seeds obtained by extraction under supercritical carbon dioxide conditions with sorbitan esters as additives (sorbitan trioleate (STO) sorbitan monolaurate (MLS) and etoxylated sorbitan monolaurate (EO20MLS)). The influence of the concentration of surfactants on the motion resistance, wear and anti-seize properties of the obtained lubricants was analysed. Two types of tests were performed: seizure, with linear load increase and constant load (four-ball device T02). The obtained test results compared to the results for the base (pure extract) to paraffin oil and rapeseed oil were related. It was found that the addition of sorbitan esters to the extract has a greater effect on the improvement of anti-seizure properties than on the reduction of resistance to movement and wear to the base.<br/><br/>
