摘　　要：通过采用大分子包覆和醇析重结晶技术制备的改性保险粉,提高了甲酸钠法保险粉粒度的同时实现了粒径窄分布,做到了本质上无尘化;利用大分子羧酸盐进行包覆,提高了还原持久性。Modified sodium dithionite,using macromolecular coating and methanol recrystallization technology,improves particle size,achieves narrow size distribution,and is essentially dust-free compared to the traditional sodium formate method.The persistence of reducibility is also enhanced by coated macromolecular carboxylate.

关 键 词：保险粉 粒径分布 还原持久性
