Vpliv površinskih aktivnih snovi na fizikalne lastnosti glicerola in njegovo trenje v mazanih kontaktihPolajnar, Marko ; Kalin, MitjanV študiji je predstavljeno kako dodajanje površinsko aktivnih snovi v mazivo vpliva na njegove lastnosti kot sta viskoznost in površinska napetost in posledično na torno obnašanje kontaktov mazanih s ... tem mazivom. Kot mazivo je bil izbran glicerol, ki je pomemben potencialni predstavnik novejših zelenih maziv. Rezultati kažejo, da dodajanje površinsko aktivnih snovi v koncentracijah do 2 ut. %, bistveno bolj vpliva na površinsko napetost (spremembe preko 50 %) kot na viskoznost (spremembe manjše od 1 %). Spremenjena površinska napetost glicerola se v nadaljevanju odraža v tem, da mazanem kontaktu dosegamo do 11 % nižje trenje.Type of material - conference contributionPublish date - 2021Language - slovenianCOBISS.SI-ID - 49981699
