Beschreibung
Zusammenfassung:	Stabilization of the phosphating quality achieved after a surface conditioning treatment with an otherwise conventional composition containing dispersed colloidal titanium, and other benefits, is achieved by causing the aqueous composition to flow at a rate of at least 80 meters per minute for at least 10 minutes after make-up, in order to achieve optimum titanium particle size and homogeneity of the composition. La stabilisation de la qualité de phosphatation obtenue après un traitement de conditionnement de surfaces au moyen d'une composition autrement traditionnelle contenant du titane colloïdal dispersé, ainsi que d'autres avantages, est réalisée en faisant couler la composition aqueuse à une vitesse d'au moins 80 mètres par minute pendant au moins 10 minutes après la préparation, afin d'obtenir une taille optimisée de particules de titane ainsi qu'une homogénéité optimisée de la composition.
