\u2018I have used TCE for years. Never had a problem. Now it\u2019s a problem!\u2019<\/p>\n
Let\u2019s face it, you are in the business of producing metal parts, not dealing with chemistry. If the solvent isn\u2019t cleaning effectively, you simply add more. You probably test for acid acceptance, but not frequently. So why isn\u2019t that enough now?<\/p>\n
Older open top degreasers used a lot of solvent through emissive losses and drag out. This meant more frequent recharging of the solvent and by default, more replenishment of the stabilizer. If you have an older degreaser and you have been cutting back on your recharging, it\u2019s likely that your parts aren\u2019t getting as clean, and your acid acceptance numbers are much lower than they used to be.<\/p>\n
If you have a newer open top degreaser, you may not be refilling as much because you were told that the machine is tighter and more efficient. However, the process of distillation, especially on newer, tighter open tops, strips the stabilizer out of the solvent.<\/p>\n
In both cases, because stabilizer is not being added as often as it needs to be, you can end up with an acidic solvent that ruins the parts and can cause leaking in the vapor degreaser cooling coils and other high contact areas. The tank will need to be drained, cleaned and passivated \u2013 and then filled with replacement TCE.<\/p>\n
Also remember – TCE that is used for vapor degreasing should be \u2018single-stabilized\u2019 or \u2018degreaser grade\u2019 \u2013 stabilizer is the product that keeps the TCE from going acid. A double stabilized product can extend the life of the cleaning bath even more.<\/p>\n
