METHOD FOR MONITORING ORGANIC DEPOSITS IN PAPERMAKING

摘要

A method for monitoring the deposition of organic deposits from a liquid or slurry in a papermaking process is disclosed. The method involves measuring the rate of deposition of organic deposits from the liquid or slurry of a papermaking process on to a quartz crystal microbalance having a top side in contact with the liquid or slurry and a second, bottom side isolated from the liquid or slurry. Also disclosed is a method for measuring the effectiveness of inhibitors that decrease the deposition of organic deposits in a papermaking process. The method involves monitoring the deposition of organic deposits of a liquid or slurry from a papermaking process or from a liquid or slurry that simulates a liquid or slurry found in a papermaking process. Either method comprises measuring the rate of deposition of organic deposits from the liquid or slurry on to a quartz crystal microbalance having a top side in contact with the liquid or slurry and a second, bottom side isolated from the liquid or slurry; adding an inhibitor that decreases the deposition of organic deposits to the liquid or slurry; and re-measuring the rate of deposition of organic deposits from the liquid or slurry on to the quartz crystal microbalance.
