The quality of cleaning is directly influenced by temperature, detergent mixture composition, mixing intensity, duration of treatment and the method of drying.
With increasing temperature improves the cleaning ability of solvents as well as cleaning quality. However, at high temperature regimen some contaminants may be fixed on the surface, while during removing dirt containing soluble and insoluble components, soluble components can be quickly removed quickly, while insoluble can still be fixed on the surface. To simultaneously remove both types of contaminants, it is advisable to reduce the temperature of the cleaning solution. During the cleaning process to prevent the defects the desired temperature must be constantly measured and maintain accurately.
When cleaning a large number of parts in a bath with cleaning solution contamination may occurs and due to re-deposition on the cleaned surface this contamination decreases the quality of treatment. It is therefore necessary to regularly replace contaminated solution with fresh solvent. The degree of contamination of the solvent is figured out basing on its resistivity or the boiling point (with grease saturation its temperature rises). To improve the quality of cleaning it is necessary to increase the intensity of mixing the solution.
An increase of cleaning time does not always allows significantly increase the purity of the workpieces. In some cases, to improve the surface finish it is advisable to repeat the treatment.
The soluble compounds, which are deposited by evaporation on the surface of the liquid may cause the formation of stains and smudges. These defects appear when you use not enough clean liquid. To remove smudges and stains the parts are subjected to more effective cleaning solutions, solvent vapor degreasing and dried on high-speed centrifuges. With this drying dissolved contaminants are removed from the surface together with the liquid under the influence of centrifugal forces before the liquid has time to evaporate. One of the methods to improve the quality of cleaning is conducting basic treatment of contaminated parts and subjecting them to intensive cleaning using special technologies.
When working with organochlorine solvents the engineers should not be allowed ingress of water as hydrolysis – the interaction of the solvent with water to form hydrochloric acid, in the presence of which the process of decomposition of chlorinated solvents is more intensive. Characteristic odor of hydrochloric acid is a signal of the presence of water in the solvent. Hydrolysis dramatically reduces the solubility of chlorinated hydrocarbons, and on the surface to be cleaned remains a large amount of chloride ions stubborn.
