摘要:
Fluorinated solvents are used for the application of fluorinated waxes to skis without impairing the physico-mechanical characteristics of the ski sole. The fluorinated waxes are applied to skis in the form of a spray or an aerosol allowing for quick and effective application of high melting point fluorinated waxes onto ski soles. The fluorinated solvent may be one or more linear, branched, cross-linked, or cyclic perfluorinated compounds having a boiling temperature ranging between 30° C. and 150° C., and preferably between 50° C. and 100° C. Fluorinated waxes can be dissolved in such solvents, and the mixtures of fluorinated waxes and solvents are stored in spray cans and are sprayed onto the ski soles as aerosols or as sprays.

Disclosed is a machining fluid admixture for cooling and lubricating a workpiece/tool interface, wherein the admixture comprises a major amount of n-propyl bromide and a minor amount of a lubricant. In other embodiments, the machining fluid consists essentially of about 30.0 to about 99.99 weight percent n-propyl bromide; from about 0.01 to about 30.0 weight percent of a lubricant; and optionally from 0.0 to about 70.0 weight percent of a fluorinated chemical. In still further embodiments, the machining fluid consists essentially of about 45.0 to about 50.0 weight percent n-propyl bromide; from about 0.01 to about 2.0 weight percent of a lubricant; and from 45.0 to about 50.0 weight percent of a fluorinated chemical. In other aspects, the present invention is directed to methods for cooling and lubricating a tool/workpiece interface. The methods comprise the steps of applying an effective amount of the n-propyl bromide-based machining formulations as disclosed herein to a part during a machining operation so as to cool and lubricate the tool/workpiece interface.
