Abstract
A lubricating composition of essentially only a lubricating oil and particles of polytetrafluoroethylene uniformly dispersed and suspended in the lubricating oil. The lubricating composition is manufactured by sonically agitating a mixture of lubricating oil and particles of polytetrafluoroethylene at sufficiently high energy levels to produce violent cavitation. The sonic agitation is provided by an ultrasonic generating device in a system whereby the mixture is sonically agitated as it continuously passes through the ultrasonic generator.
Claims7
A process for producing a lubricating composition comprising the steps of:
- mixing the lubricating oil with from about 1% to about 20% by weight of polytetrafluoroethylene particles of between about 1 and about 200 microns in size;
- and,
- violently sonically agitating the mixture at an energy density sufficiently high to cause cavitation of the mixture.
A system for producing a lubricating composition consisting of an emulsion of polytetrafluoroethylene and lubricating oil comprising:
- lubricating oil supply means;
- polytetrafluoroethylene supply means;
- mixing means for admixing the lubricating oil and polytetrafluoroethylene particles;
- sonic generating means for continuously agitating the admixture to cause cavitation and create a substantially stable emulsion as the admixture continuously moves through the sonic generating means;
- and,
- means for continuously transferring the admixture through the sonic generating means.
