REVIEW: USE OF OPTICAL BRIGHTENING AGENTS (OBAs) IN THE PRODUCTION OF PAPER CONTAINING HIGH-YIELD PULPS
The efficiency of optical brightening agents (OBAs), also known as fluorescent whitening agents (FWAs), has long been of interest in the production of uncoated fine paper, particularly in uncoated fine paper grades containing high-yield pulp (HYP). The increasing levels of whiteness and also the increasing HYP substitution in fine papers has made OBA efficiency an important issue. This paper su...

متن کاملImprovement of Paper Properties of Recycled Unbleached Softwood Kraft Pulps by Poly(allylamine Hydrochloride)
Polyelectrolytes containing amine functional groups such as PAH (poly(allylamine hydrochloride)) can be useful, under certain conditions, for improving paper strength. In this work, the charge density of PAH was determined at different pH and ionic strengths; PAH adsorption onto the cellulosic fibers was characterized, and the effects of low PAH dosage on the papermaking properties were evaluat...
متن کاملData Warehousing for Manufacturing Yield Improvement
This paper will describe the data warehouse/decision support/data mining system that we have developed to improve disk drive manufacturing yields in the IBM Storage Technology Division. The data warehouse combines operational data from our disk, wafer and head stack processing plants. Data is extracted weekly, cleansed and correlated with the test results for the disk drives assembled from the ...
