Cleaning Process
An industrial surface cleaning technique that utilizes solvent vapors to dissolve and remove oil, grease and other contaminants from metal components is widely used in precision manufacturing. The process of vapor degreasing relies on a specialized chamber where solvent is heated to its boiling point to create a dense vapor zone. This method ensures that the surfaces of processed parts are completely clean and dry.
Technical Execution
Parts to be cleaned are suspended within the vapor zone, where the relatively cool metal causes the solvent vapor to condense back into liquid. This condensation action dissolves the contaminants on the metal, carrying them down into the boiling solvent reservoir at the bottom of the tank. Because the solvent has a lower boiling point than the oil and grease, only clean solvent vapor rises to contact the incoming parts.
Heating elements and cooling coils must be carefully balanced to prevent the solvent vapor from escaping the chamber. Operators must run the system according to precise thermal profiles to ensure complete soil removal.
Environmental Regulation
Strict environmental regulations govern the types of chlorinated or fluorinated solvents used in these degreasing machines. Many traditional solvents have been phased out due to their ozone-depleting properties or health risks for workers. Modern systems use closed-loop designs to recycle the cleaning fluids.
