| description | Used lubricating oils can be rejuvenated by passing the oil through a filter system comprising a hollow solid composite that contains a thermoplastic binder and an active filter media of a chemically active filter media, a physically active filter media, or mixtures thereof. In a preferred embodiment, the composite is formed by forcing a substantially uniform mixture of thermoplastic binder particles, active filter media particles, solvent 600 Neutral base oil, and sodium stearate through an extrusion die of substantially uniform cross-section, wherein the mixture is subjected to heat, pressure, and cooling to consolidate the mixture so that it emerges from the die as a hollow solid composite. Most preferably, the composite will surround an inactive filter media located within the filter system.
Des huiles de lubrification usées peuvent être régénérées en faisant passer l'huile à travers un système de filtre comprenant un composite solide creux qui contient un liant thermoplastique et un milieu de filtre actif d'un milieu de filtre chimiquement actif, un milieu de filtre physiquement actif, ou des mélanges de ceux-ci. Dans un mode préféré de réalisation, le composite est formé en faisant passer de force un mélange sensiblement uniforme de particules d'un liant thermoplastique, des particules d'un milieu de filtre actif, une huile de base neutre à solvant 600 et un stéarate de sodium à travers une matrice d'extrusion ayant une section sensiblement uniforme, puis en soumettant le mélange à de la chaleur et à de la pression, et en refroidissant le mélange pour le consolider afin qu'il sorte de la matrice sous la forme d'un composite solide creux. Préférablement, le composite entoure un milieu de filtre inactif placé dans le système de filtre. |
