【摘要】 研究的目的是在对造纸工艺不作重大改变的条件下,用助留剂阳离子淀粉对重质碳酸钙进行在线表面改性,该方法改性的重质碳酸钙能提高其在纤维中的留着率。实验发现,用阳离子淀粉对重质碳酸钙在线进行表面改性,对提高其留着率来说是相当经济的选择。更多还原

【Abstract】 The purpose of this research is that under the condition of no significant change in paper-making process,the cation starch is used as retention agent to make the ground calcium carbonate(GCC) surface modification online.This method can improve the retention rate of GCC in fibre.The test results show that the surface modification of GCC by cation starch for improving its retention rate is a rather economical choice.更多还原
