A lubricant (Lithium-Sodium) of Syrian petroleum-based stocks and
thickener material depends in its preparation on Skinless chicken fat, was
manufactured at different ratios.
A study of physical - chemical properties of manufactured grease types w
as
carried out (compared with Syrian standard specification 791/2008) by using
standard methods which included: grease state, penetration degree, drop point,
free acidity (as oleic acid)% by weight, grease resistence to water, evaporating
at 90° C, and corrosion of copper plate. Where the results show that the best
type of grease is of 30% ratio.
