Definitions
- hydrochlorofluorocarbon (HCFC) based solvents have been developed in the last few years to provide more environmentally acceptable alternatives to CFC based vapor phase decreasing and defluxing processes. While these materials have been shown to be excellent CFC substitutes for a variety of cleaning
- the substrate is immersed in the rinsing agent, sprayed with the rinsing agents exposed to vapors of the rinsing agent, or any combination of the above. When removed from the vapor the part is essentially clean and dry.
- the non-aqueous cleaning system of this invention utilizes a two tank cleaning process wherein a first tank contains the organic solvent and a second tank contains the rinsing agent.
- the parts or substrates to be cleaned may be conveyored from the cleaning tank to the rinsing tank utilizing known conveyor or hoist means.
- the tanks may be part of conventional or known in-line conveyorized degreasing/defluxing equipment, separate open top defluxing tanks, or open top defluxing tanks modified to contain the cleaning and rinsing tanks or sumps.
- the organic cleaning solvent can be selected from linear or branched alkyl or alkanol
- the organic cleaning fluid may also consist of hydrocarbon containing olefinic moieties which have been substituted with R 1 -R 12 groups, wherein R 1 -R 12 hydrogen atoms or alkyl groups containing 1-6 carbon atoms or both may comprise the
- R H, hydroxyl
- organic cleaning fluids applicable to this invention may be comprised of:

- the fluorocarbon rinse solvent may be any fluorocarbon rinse solvent.
- the boiling point is preferably between 25°C and 120°C with at least 60% of fluorine in the compound.
- the compounds preferably have a linear or branched chain. Providing flammability suppression can be maintained through the use of suitable vapor blanketing species.
- the rinse solvent may also be selected from compounds or mixtures comprised of other linear, branched, or cyclic alkyl or aryl alcohols, esters, vitro, nitrocyclo, or nitrile compounds, ethers, ketones, hydrocarbons, and other non-aqueous media.
- Figure 2 is a schematic view depicting an alternative embodiment of equipment that may be used in the present invention.
- Figure 3 is a schematic view depicting a further alternative embodiment of equipment for use in the present invention.
- fluorocarbon solvent preferably having a lower boiling point than the hydrocarbon solvent.
- the fluorocarbon solvent has at least slight
- the preferred hydrofluorocarbons are
- solubility of the rinsing fluorocarbon solvent for the hydrocarbon cleaning solvent is defined as ⁇ 2
- conveyor means may be used to successively convey the parts from the cleaning sump 15 to the rinsing sumps 20 and 25.
- the organic cleaning fluid in cleaning tank 15 may optionally be mixed with a fluorocarbon type solvent.
- the cleaning fluid in this case would be warmed to a sufficient temperature to boil off the fluorocarbon, where the boiling point of the fluorocarbon should be at least 10°C. lower than that of the organic hydrocarbon fluid.
- the mixture is
- the cleaning fluid mixture may or may not require a surfactant additive to ensure phase homogeneity between the organic hydrocarbon and the fluorocarbon solvents.
- the fluorocarbon which was boiled off would be maintained at a constant concentration in compartment 15 by either returning the vapor condensate back to this compartment and/or pumping fluid from the rinse compartment (s) 20,25 back to this sump through control with a volume or level sensingtransducer (not shown). In this variation of
- heating coil 33 would be preferred and heating coil 34 may not be
- the rinse sump 20 may contain a saturated solution of the hydrocarbon based cleaning fluid and the fluorocarbon based rinsing solvent. The fluids are selected so that the hydrocarbon phase separates at some low concentration (i.e., less than 10 mole %) in the fluorocarbon and floats to the top of the more dense fluorocarbon, providing a cascading effect back into the cleaning sump 15.
- the rinse sump(s) 25a or 25b may also in turn cascade pure rinse solvent into sump 20 to maintain its level and also to directionally provide a flow skimming action to sweep the separated organic laye towards the boil sump 15.
- the fluorocarbon rinse solvent and the hydrocarbon cleaning solvent can be cascaded or pumped back to their respective sumps to ensure that sump liquid volumes are maintained.
- the hydrocarbon cleaning zone 15 may be separated from the rinsing zones 20 and 25 by being provided within separate structures 11 and 12. This configuration i8 intended to provide the ability to retrofit conventional solvent vapor degreasing or
- the residual hydrocarbon 20 carried over from cleaning sump 15 may be mechanically separated out as described in Figure 1 and recycled back with a pump 45 (as schematically depicted) in view of the physical separation of the two cleaning zones which would prevent cascading as in the previous embodiments.
- the organic cleaning solvent in cleaning sump 15 is immiscible or of low miscibility with the fluorocarbon-based rinsing solvent in rinsing sump 25.
- the first rinsing zone is provided with a coupling solvent (such as an alkanol like butanol, or another fluorochemical such as trifluorobenzene, or any other type of hydrocarbon) wherein the fluorocarbon solvent is miscible with the coupling solvent.
- a coupling solvent such as an alkanol like butanol, or another fluorochemical such as trifluorobenzene, or any other type of hydrocarbon
- the fluorocarbon solvent has a lower boiling point than either the organic cleaning solvent or the coupling solvent.
- the fluorocarbon in sump 25 primarily serves the purpose of .blanketing the
- hydrocarbons All of these oils are used in the metal working industry for cooling and lubricating purposes.
- the synthetic oils contain synthetic polymer with additives containing fatty acids and amines.
- the semi- synthetic oils are mixtures of the petroleum and
- the cleaning process used for tests to demonstrate this invention consisted of 30 second immersion of a coupon in the organic cleaning solvent followed by a 30 second immersion in the fluorochemical solvent and a 30 second rinse above the liquid in the cooling coil zone with the condensing vapors of the fluorochemical solvent.
- the amount of soil on the coupon before and after cleaning was determined with a
- CO 2 coulometer which measures to microgram sensitivity the amount of organic residue, expressed in carbon units, on a surface.
- the sample of residue on the coupon is introduced into a combustion furnace via a sample boat, and is combusted in oxygen atmosphere at a temperature of 650°C.
- the resulting CO 2 and other combustion products pass through scrubbers to remove any interfering halogens, sulfur, nitrogen oxides and water.
- the gas then passes to the coulometer cell which contains an indicating solution. As the gas stream passes through the solution, CO 2 is quantitatively absorbed, and reacts with a chemical in the solution to produce a titratable acid.
- An electric current Is then automatically adjusted to neutralize the solution, the total current is
- micrograms of carbon The sensitivity of this method is +/- 0.01 micrograms carbon, which is one of the most sensitive methods to reproducibly analyze carbon components on a surface. Since all oils cleaned in this invention are primarily organic in nature, the monitoring of carbon content is an excellent way to determine with high reproducibility and sensitivity the amount of organic soil on a substrate.
- HFC 52-13 is a branched hydrofluorocarbon (C 6 F 13 H) used as the fluorocarbon
- the methyl ester is effective in removing petroleum based oil from metal coupons at room

- Soiled coupons were immersed in a mixture of the dibasic esters with HFC-365 (CF 3 CH 2 CF 2 CH 3 ) at 56°C for 30 seconds, followed by a 30 second immersion in HFC- 365 at ambient temperature and a 30 second vapor rinse with HFC- 365. The following results were noted:
- fluorochemical solvent alone is sufficient to completely clean the surface.
