摘要
"An improvement in high performance kaolin pigment, paper coating paint comprised of high performance kaolin pigment in method for producing high performance kaolin pigment", wherein only coarse kaolin is used, said pigment exhibiting an ISO whiteness preferably higher than 88.5; a grain size distribution of at least 96% lower than 2 µm and at most 15% lower than 0.2 µm; a Hercules viscosity at 18 dines of at least 200 RPM in pulps with a concentration of solids of 70 -71 %, thus producing a coating paint that has an ISO whiteness higher than 88.5 and lower than 91.0; a grain size distribution of at least 96% lower than 2 µm and at most 15% lower than 0.2 µm and a Hercvules viscosity at 18 dines of at least 200 RPM in pulps with a solids concentration of 70 - 71 %, said manufacturing process providing an overall recovery of 49%.
