Description
***.* i-Przyklad II. Na tacki jak w przykladzie I naniesiono po 0,1 ml oleju przekladniowego Hipol 15 i ogrzewano na plycie grzejnej w temperaturze 240°C. Nastepnie zdjeto je w odstepach jednominutowych, ostudzono do temperatury otoczenia (21°C) i rozpuszczono kazda próbke ogrzewanego oleju w 1 ml n-heptanu.***. * i-Example II. 0.1 ml of Hipol 15 gear oil was applied to the trays as in Example 1 and heated on a heating plate at 240 ° C. Then they were taken off at one-minute intervals, cool to ambient temperature (21 ° C) and dissolve each sample of heated oil in 1 ml n-heptane.
Rozpuszczone próbki naniesiono pipeta na bibule chromatograficzna Whatman 2. Na bibule powstala pierwsza centryczna, ciemna plama z osadem oleju ogrzewanego przez 2 minuty, przez co stabilnosc termooksydacyjna oleju przekladniowego Hipol 15 okreslono umownie jak 2.The dissolved samples were pipetted onto Whatman 2 chromatography paper. The first was made on the paper centric dark spot with oil residue heated for 2 minutes, making thermo-oxidative stability The Hipol 15 gear oil is conventionally referred to as 2.
Stosowanie wynalazku. Zgodnie z wynalazkiem sposób oznaczania stabilnosci termooksydacyjnej olejów smarowych nadaje sie do stosowania w szybkich analizach olejów smarowych, pochodzenia naftowego, pod wzgledem ich przydatnosci eksploatacyjnej.Use of the invention. According to the invention, a method for determining the thermo-oxidative stability of oils Lubricants are suitable for the rapid analysis of lubricating oils, petroleum, under in terms of their operational usefulness.
