Differences of Kaolin Quality for Glass Fibers Made in China and Abroad and Improving Measures of Kaolin Quality Made in China

Kaolins are one of important materials for E-glass fibers,which accounts for about 1/3 of blend mass.But the high-end market of kaolin for glass fibers was dominated by imports in China.Three kinds of kaolin samplesproduced by ITC,Yichang and Yunnan for glass fibers were studied in this paper.The differences in chemical composition,phase,microstructure and granulometric composition were compared in detail by XRS,XRD,SEM and LPS.The research found that products of ITC had obvious advantages in product purity...
