Current chemistry trends recommend using parts cleaning solvents with vapour degreasers for precision cleaning applications. Because similar things dissolve similar things using a parts cleaning solution is a good idea.
Oil and grease are excellent examples of non-polar soils that are better dissolved by non-polar solvents. Although it is true that in some circumstances, you may use an emulsifier or detergent to make water operate, it is crucial to remember that the operation has a very little process window.
What Is a Clean Solvent?
Having clean solvents is necessary when it comes to washing and cleaning applications for components. This is because the cleaner the solvent, the more effective it will be at removing pollutants from the parts that your firm is producing.
When organic solvents are first acquired, they are “clean,” which means that they are free of impurities that the solvent may pick up while being used in an application to wash or clean parts.
This uncontaminated or virgin solvent can be used repeatedly until it reaches its absorption capacity and cannot take up any more pollutants. When this occurs, the dirty parts cleaner fluid will either need to be swapped out for clean solvent or recycled so that it may be used again.
What Happens After Your Solvents Are Dirty?
Both the act of purchasing virgin solvents and the act of disposing of polluted solvents properly can be financially burdensome. Distilling contaminated solvent to produce clean solvent can be an efficient way to tackle the problem of how to recycle and recover your solvent, which is a suitable solution for an application that involves washing or cleaning parts.
Distillation will result in a clean solvent that has been recycled or recovered. The recovered solvent will have sufficient concentration to function admirably in applications involving the washing and cleaning of components. It is possible for the solvent to take up water and turn into an azeotrope. However, this will depend on the solvent that is being treated.
The amount of water present will be subject to regulation, which is dependent on the solvent capacity. In most cases, the “contaminant” that is going to be discovered in the recycled or recovered solvent is going to be water. If it is desired to have less water, a desiccant can be used with the solvent to help remove a significant amount of the water.
