Kaolin/Ultra fine & High Whiteness Calcined Ka

[product name]HS-901B kaolin/Ultra Fine & Super White calcined kaolin [Character and Performance]The crystal is in laminar structure of pseudo-hexagonal kaolinite platelets. Super fine particle with narrow distribution, little residue on 325 mesh, and low abrasion; Great whiteness, covering power, light dispersion, fluidity and viscosity; Excellent extender of titanium dioxide for improving its performance; The coating containing HS-901B has good performance in water-preserving, fluidity, viscosity. It can improve the property of paper such as whiteness, smoothness, opacity, ink absorbency, printability and luster, especially the whiteness and ink absorbency.[Application] Medium-quality paper-making such as thermal sensitive paper, decorating paper, coated paper and paper board, etc.[Physical specification]Specification HS-901BWhiteness (%)93.5%Particle size (-2μm,%)83.5-86Residue on 325 mesh (%)≤0.004Oil absorption (g/100g)60-70pH 6.0-8.0Water content (%)≤1.0Abrasion (mg/2000 times)≤3.3Refractivity 1.62
