PHYSICAL AND CHEMICAL PROPERTIES OF MODIFIED LUBRICANTS FOR WEAVING MACHINES
The effects of Taunit-M carbon nanotubes on the physical and chemical properties of lubricants for textile looms have been considered. High stability of suspensions of carbon nanoparticles in liquid lubricants has been shown by spectrophotometric method. The rotational viscometry method proved that the addition of carbon nanotubes in concentrations up to 2.5 wt. % does not change the character of the lubricant flow, while the viscosity dependence on the concentration is exponential in character. Inertness of carbon nanotubes with the surface tension of suspensions has been revealed: adding nanoscale additive in concentration up to 2.5 wt.% does not result in a significant change in the surface tension coefficient. Modification of lubricants with carbon nanotubes also increases the heat dissipation from the friction zone, which improves the tribological characteristics of suspensions.
