文摘内容 This paper reports the study of modified filler gradetalc powder on filler retention. A1203 3H20 alone orA1203~ 3H20 and P205 in combination have been usedto modify talc powder. It is concluded that theoptimum retention effect of talc can be achieved bycovering it with 5% A1203 ~ 3H20. Adding 30% filler,the retention from 2.5% P205, 2.5% A1203 3H20covered talc powder is higher than that of 5% A1203~3H20 covered talc powder, which are 29.76% and11.35% higher than that of the unmodified talcpowder respectively。
