Studies on the activation of the pre-kininogenin-kininogenin (pre-kallikrein-kallikrein) system by sulfated polysaccharides and kaolin
The activation of pre-kininogenin to kininogenin (pre-kallikrein to kallikrein) is one of the steps in the series of reactions of a complex system, linked also to fibrinolysis and coagulation, that leads to kinin release ...
ANALYSIS OF PULP BLEACHING SEQUENCES IN THE RETENTION OF KAOLIN AND IN THE PROPERTIES OF PAPER
(Univ Federal Vicosa, 2015-11-01)
The aim of this study was to investigate the influence of different bleaching sequences at different amounts of kaolin in paper properties. To do that, three different ECF bleaching sequences were taken to the same ...
Pore structure characterization of kaolin, metakaolin, and their acid-treated products using small-angle X-ray scattering
Pore structure of dealuminated kaolin and metakaolin was studied by small-angle X-ray scattering (SAXS). Both parent kaolin and metakaolin have about 10% of the total pore volume provided by globular pores with 105 Å mean ...
