高品质瓷土级浆状重质碳酸钙的研制及应用

Development and Application of High-quality Clay Cevel Pasty Calcium Carbonate

将国产瓷土在线添加到碳酸钙研磨过程,通过适当的研磨工艺,获得具有固含量高、粘度及回粘度低、流变性好、粒径分布范围窄、白度及光泽度高等特点的高品质瓷土级浆状重质碳酸钙。该产品用于生产高档涂布纸的加工颜料涂料中,能很好地提高涂布纸纸面的平滑度、白度,改善纸的外观,提高涂布纸的亮度、不透明度和光泽度,具有良好的涂层遮盖性,提高成纸质量。

China clay add into calcium carbonate grinding process on line, by appropriate grinding technics, obtain solid content high, viscosity degree and returned viscosity degree are low, stream degeneration is good, grain-size distribution scope is narrow, white degree and glossiness are advanced ,high-quality clay level pasty quality calcium carbonate. This product is used in coating of machining pigment which produce high quality coating paper. Can improve the paper outward appearance smooth degree, white degree, improving paper appearance, improve coating paper brightness, opacity and glossiness, have fine coating cover character, improve final paper quality.
