Lubrication and tribological properties of palm oil mixed with organo zinc compound

Friction can be defined as the resistance to motion of one object moving relative to each other. At certain application, frictions are required to be used such as for a brake application. Unnecessary friction creates wear, hence reducing the lifespan of equipment and machinery. One of the solution b...

The oil samples were prepared by mixing organo zinc compound additive; Zinc Dioctyldithiophosphate (ZnDoDP) or Zinc Diamyldithiocarbamate (ZDDC) between 0 wt. % to 3.0 wt. % concentrations interval with commercialized palm oil and then were homogenized using ultrasonic homogenizer (0 wt. %, 1 wt. %, 1.5 wt. %,2.0 wt.%,2.5 wt. %, 3.0 wt. %) Afterward, the oil sample was tested for their oil properties in accordance to engineering standard in terms of elemental analysis test, viscosity index test, small scale flashpoint test and potentiometric titration acid number test (automatic).

As a conclusion, palm oil mixed with organo zinc compound as additive enhanced the lubrication properties at 2.0 wt.%, decrease about 20.5% (ZDDC) and 7.9% (ZnDoDP) in their viscosity index and decrease the value of flashpoint about 11.6% (ZDDC) and 15.1% (ZnDoDP) from commercialized palm oil with 0 wt. % additive . Meanwhile, as for their acid number, there are an increased value of about 61% (ZDDC) and 97% (ZnDoDP) from conventional transmission oil. In terms of tribological properties, it shows that at 2.0 wt. %, about 22 % (ZDDC) and 60% (ZnDoDP) value decrease of wear scar diameter from pure palm oil. Meanwhile, the value of the coefficient of friction also decreases if compared to commercialized palm oil with 0 wt. % additive about 36.8% (ZDDC) and 43% (ZnDoDP) resulted in producing an alternative lubricant which can be applied in industry in as substitution to conventional mineral based oil as lubricant. 2021 Thesis http://eprints.utem.edu.my/id/eprint/26063/ http://eprints.utem.edu.my/id/eprint/26063/1/Lubrication%20and%20tribological%20properties%20of%20palm%20oil%20mixed%20with%20organo%20zinc%20compound.pdf text en public http://eprints.utem.edu.my/id/eprint/26063/2/Lubrication%20and%20tribological%20properties%20of%20palm%20oil%20mixed%20with%20organo%20zinc%20compound.pdf text en validuser https://plh.utem.edu.my/cgi-bin/koha/opac-detail.pl?biblionumber=121165 mphil masters Universiti Teknikal Malaysia Melaka Faculty of Mechanical Engineering Abdollah, Mohd Fadzli
