Papier d'essai d'asphalte

Papier filtre qualitatif de grade 627 - 100 cercles - 9,75 pouces de diamètre

Papier filtre pour tests d'asphalte. Doté d'une capacité de charge élevée, il est presque deux fois plus épais que le grade 237.

Les papiers filtres qualitatifs standard conviennent aux applications pliées en quadrant ou à écoulement par gravité. Ces qualités contiennent une forte teneur en alpha-cellulose, ce qui leur confère une grande pureté, mais elles s'affaiblissent à l'humidité. La résistance intrinsèque des qualités standard (non traitées) ne pose aucun problème pour les applications courantes pliées en quadrant. Nous déconseillons l'utilisation de ces qualités pour les applications sous vide ou en milieu humide.

Les papiers filtres qualitatifs d'Ahlstrom sont, par définition, recommandés pour les méthodes analytiques qui déterminent ou identifient les constituants particulaires d'un mélange, quelle que soit leur quantité. Les papiers filtres qualitatifs sont souvent utilisés pour les travaux de séparation de routine qui requièrent une pureté élevée et des performances constantes.
