APPLICATION OF ETHERIFIED DICYANDIAMIDEFORMALDEHYDE CONDENSATION COPOLYMER IN PAPERMAKING WET END

摘要：

　　In this paper,dicyandiamide-formaldehyde condensation copolymer was etherified and applied to the wet end,which was in order to get a better performance of retention and drainage.The retention was used as performance standard,and the three influencing factors were discussed,including dosage of DDF,pH of pulp and mixing time.The amount of dicyandiamide-formaldehyde condensation copolymeris 0.03%,the reaction timeis 30s,the pH of the pulpis 7.Compared with others retention and drainage agents,it has a better performance.
