Vapour degreasing is an amazing technology. It is perfect for products that cannot be introduced to water and/or other liquids. This is because the vapour degreasing process keeps the physical liquids away from the product. If you’re wondering if this method of cleaning is right for you, it’s important to understand the basics. So, as vapour degreasing experts, we’ve outlined the process to get you started.
What is Vapour Degreasing?
Vapour Degreasing is the procedure of degreasing and cleaning parts using condensed solvent vapours. The process utilises the hot vapours of a chlorinated or fluorinated solvent to evacuate soils, especially oils, greases, and waxes.
How Does it Work?
A vapour degreasing unit comprises of a steel tank with a heated solvent reservoir or sump at the base and a cooling zone close to the top.
To start with, a measured amount of heat is pumped into the chamber. This boils the chemicals and generates the hot solvent mixed gas (vapour.) Because the hot gas is heavier than the air, it pushes the air up and fills the tank up to the cooling area.
Furthermore, the vapour from the chemicals travels to the top of the cooling area of the machine. The temperature difference between the hot gas and the degreasing cold item, causes the chemical gas to condense onto thus attach itself to the item and dissolve the grease, wax, etc.
Understanding The Process
The soils expelled from the work pieces boil at much higher temperatures than the solvent. Therefore, bringing the development of unadulterated solvent vapours. This is despite the fact that the boiling solvent may be very defiled with soil from past work parts.
In vapour degreasing, the parts are heated by build up of the solvent vapours to the boiling temperature of the degreasing solvent. Moreover, they dry in a flash as they are pulled back from the vapour zone. Solvent soundness is typically controlled by the expansion of stabilisers when the solvent is fabricated. Most regular chlorinated solvents all oblige stabilisers to perform effectively in vapour cleaning.
The Framework
The least complex type of degreasing framework enables the build up of solvent vapour. There may be a need of a spray stage if the work piece contains visually impaired openings or breaks that are not available to the vapour. Therefore, if the soil can’t be uprooted by the vapour, the framework then comprises of vapour – spray – vapour stages. Different techniques incorporate warm liquid-vapour, boiling liquid/warm – liquid-vapour frameworks. Likewise ultrasonic cleaning can be utilised as a part of conjunction with the vapour degreasing process.
At the point when a ferrous metal is vapour degreased, organic films are generally evacuated. After that, the metal is exceedingly helpless to atmospheric consumption. When steel parts with a high surface completion (e.g. anti-friction direction) are being degreased and finish rust counteractive action is coveted, rust flushing ought to be incorporated as a vital piece of the degreasing framework.
