Kaolin and the plastic raw material combination form plasticity clay group and has certain dry strength performance. Combined with the determination of ability, is in the kaolin added standard quartz sand (the quality composition of 0.25-0.15 graded accounted for 70%, 0.15 -- 0.09 mm fraction 30%). With its can still keep plastic clay when group the highest sand content and drying after the bending strength to judge its height, incorporation of sand is more, describe the kaolin combining ability is stronger. Usually all plasticity of kaolin combined with strong ability.
325 mesh level B kaolin high whiteness, hiding power, light scattering performance is good, can provide good performance, adjust the cover coating gloss, replacing part of the titanium pigment reduce production cost; Low content of impurities, chemical inertness, and strong any other additives, solvents reaction
