CA 2698107

A method for monitoring the deposition of one or more organic materials dispersed in an aqueous medium in a papermaking process comprising: measuring the rate of deposition of the organic materials from the aqueous medium on-to a quartz crystal microbalance having a top side contacting with the aqueous medium coated with a layer containing a non-swelling epoxy resin or a silicon containing polymer, and a second, bottom side isolated from the aqueous medium is disclosed. Additionally, a method for measuring the effectiveness of an inhibitor that decreases the deposition of the organic materials in a papermaking process is also disclosed.

L'invention concerne un procédé servant à suivre dans un procédé de fabrication de papier le dépôt d'une ou plusieurs matières organiques dispersées dans un milieu aqueux, comprenant la mesure de la vitesse de dépôt des matières organiques provenant du milieu aqueux sur une microbalance à cristal de quartz ayant une face supérieure en contact avec le milieu aqueux recouverte d'une couche contenant une résine époxyde ne gonflant pas ou un polymère contenant du silicium et une seconde face inférieure isolée du milieu aqueux. En outre, l'invention concerne également un procédé servant à mesurer l'efficacité d'un inhibiteur qui diminue le dépôt des matières organiques dans un procédé de fabrication de papier.
