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.
This research includes a comparative study of the physical
properties of compressed wood factory of pine cones and tree Alazdrecht.
This study demonstrated the feasibility of manufacturing slabs of pressed
wood from pine cones and the remnants of pruning trees Alazdrecht and
physical attributes of a good، which contribute to the lifting of economic
value to them.
This paper presents an experimental study to determine the physical and
some other important properties of certain waste materials, in order to
identify the appropriate field of their recycling. The experiments have
been carried out using five proposed materials, namely: corn cob, peanut
peel, straw, pine cone, and sticks of the stem Thistle Syrian plants.
