ENHANCED METHOD FOR MONITORING THE DEPOSITION OF ORGANIC MATERIALS IN A PAPERMAKING PROCESS

摘要

Disclosed is 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 cured non-swelling epoxy resin or a silicon containing polymer, and a second, bottom side isolated from the aqueous medium. Also disclosed is a method for measuring the effectiveness of inhibitors that decrease the deposition of one or more organic materials in a papermaking process comprising: a. monitoring 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 onto a quartz crystal microbalance having a top side contacting the aqueous medium coated with a layer containing a nonswelling epoxy resin or a silicon containing polymer, and a second, bottom side isolated from the aqueous medium; b. adding an inhibitor that decreases the deposition of the organic materials from the aqueous medium; and c. re-measuring the rate of deposition of the organic materials from the aqueous medium onto the coated surface of the quartz crystal microbalance.
