PRE-TREATMENT , SURFACE PREPARATION , DEGREASING & CLEANING
With chlorinated solvents such as Perchloroethylene , as little as 1 % ( or even lower ) of solvent residue can be found in the waste stream . Based on 10,000 kg of oil which may enter the cleaning machine per year that needs to be cleaned off , this would result in just about 100 kg of solvent residue in the waste stream , and therefore an approximate total of 10,100 kg of waste per year .
If there is a significant amount of oil that needs to be removed in the cleaning process , the good distillation behavior of solvents can be a great advantage which can ensure minimal wastage and reduced carbon footprint .
4 . Low energy usage
Thanks to their low surface tension and viscosity , solvents dry quickly and completely , leaving no moisture or residue on parts after they exit the vapor degreaser . In comparison , energy required to dry metal parts after aqueous cleaning can be 10 times higher .
During the distillation process , solvents also require much less energy to heat to boiling temperature because of their lower specific heat capacity . It also requires less energy for it to evaporate , as illustrated in the table .
Every cleaning process comes with its unique requirements and challenges . By no means can solvent be a one-size-fits-all solution . The choice of the right cleaning solution therefore depends on your requirements , goals and expectations . Our free whitepaper " 10 key questions to consider when selecting the right cleaning agent " will guide you to make the optimal cleaning decision that balances technical , economic and environmental requirements .
