印刷用纸对白度要求较高,目前常采用漂白化学原生浆生产。实验尝试加填原位沉积CaCO3_改善废纸浆生产印刷用纸的光学性能,以提高印刷用纸生产过程中废纸浆利
Printing paper on the higher degree of whiteness, the current use of bleached chemical primary pulp often used. Experimental attempts to fill in-situ deposition of CaCO3_ to improve the optical properties of waste paper pulp production of paper in order to improve the printing paper production process of waste paper pulp
