摘　　要：主要研究磷石膏在造纸表面施胶剂中的应用。以磷石膏替代一定比例的表面施胶淀粉,用于瓦楞原纸表面施胶。实验表明:50%的磷石膏替代淀粉对原纸施胶后的环压指数为7.69 N.m/g,拉毛速度为2.29 m/s,加入0.3%A K D施胶后抗水时间为163.4 s,满足了瓦楞纸指标要求。磷石膏综合利用变废为宝,既降低造纸生产成本,又节约粮食资源。The application of phosphogypsum in paper surface sizing agent was studied.A certain proportion of surface sizing starch was replaced by phosphogypsum for corrugated base paper sizing.The experimental results show that when phosphogypsum is used to replace a half of starch,the ring pressure index is 7.69 N.m/g and the picking speed is 2.29 m/s;the water resistance time is 163.4 s after 0.3%AKD added,which meets the requirements of corrugated paper sizing.Turning phosphogypsum from waste into treasure not only reduces the production cost of papermaking,but also saves a lot of grain.
