METHOD FOR EVALUATING THE CAPACITY OF A CLEANING BATH CONTAINING AT LEAST ONE ANIONIC OR IONIC SURFACTANT TO CARRY OUT A ROLE OF DEOILING PARTS

Method for evaluating the capacity of a cleaning bath containing at least one anionic or ionic surfactant to carry out a role of deoiling parts, in which: a sample is withdrawn from the bath and the amount of acid needed in order for this sample to achieve a neutral pH is measured; the oil content o...

Zusammenfassung:	Method for evaluating the capacity of a cleaning bath containing at least one anionic or ionic surfactant to carry out a role of deoiling parts, in which: a sample is withdrawn from the bath and the amount of acid needed in order for this sample to achieve a neutral pH is measured; the oil content of the bath to be evaluated is evaluated; the surfactant content of the bath is evaluated; then, as a function of the evaluated oil content of the bath to be evaluated, of the evaluated surfactant content of the bath to be evaluated and of a predetermined rule, the current capacity of the bath to fix oil in the form of micelles with the aid of surfactants that it contains is verified. Méthode d'évaluation de la capacité d'un bain de nettoyage contenant au moins un tensioactif anionique ou ionique à assurer une fonction de déshuilage de pièces, dans laquelle : on prélève un échantillon du bain et on réalise une mesure de quantité d'acide nécessaire pour que cet échantillon atteigne un pH neutre; on évalue la teneur en huile du bain à évaluer; on évalue la teneur en tensioactifs du bain; puis en fonction de la teneur évaluée en huile du bain à évaluer, de la teneur évaluée en tensioactifs du bain à évaluer et d'une règle prédéterminée, on vérifie la capacité courante du bain à fixer de l'huile sous forme de micelles à l'aide de tensioactifs qu'il contient.
