Method for analyzing cylinder coating on tissue machines
Karlstad University, Faculty of Technology and Science, Department of Chemical Engineering.
2008 (English)Conference paper, (Other (popular science, discussion, etc.))
Abstract [en]

Samples of coating have been taken at different positions on a running Yankee cylinder

to analyze the content. The scrapings of the coating were obtained by collecting material

from the cleaning doctor and by scraping coating with a hand scraper in between the

cleaning doctor and the spray boom. The conditions on the Yankee dryer surface were

varied by varying specific creping additives. Chemical and morphological analyses were

made on the samples. The chemical analysis comprised carbohydrate analysis and

nitrogen analysis. Analyses of the scrapings were compared with analyses of the creped

paper. Replicas of the coating layer were made with a silicon rubber to show the

microstructure. The coating was thick and appeared patch-wise and it contained fiber

fragments. The chemical analysis indicates that the nitrogen content was higher for the

coating close to the cylinder. The sampling method seems to work well, since the

nitrogen content increases with an increased amount of applied adhesive
