SYNTHESIS AND APPLICATION OF THE NOVEL PAM EMULSION AS PAPER DRY-STRENGTHING AGENT

INTRODUCTIONIn china, there are some defects in qualities and strength properties of fiber furnishes consisting largely of wheat straw pulps and waste papers valued more and more, which causes a barrier to the development of enterprises and evaluation of product qualities 1]. Meanwhile, the addition of more fillers and lower basis weight products make it further predominant that maintains slurries relatively higher reinforce. The uses of strength agent for paper contribute the best measur…

SYNTHESIS AND APPLICATION OF THE NOVEL PAM EMULSION AS PAPER DRY-STRENGTHING AGENT

The synthesis of a novel type of polyacrylamide emulsion as dry-strengthing agent was studied in this paper. Several strength agents were obtained by changing reaction conditions such as reaction time, species and doses of initiator, reaction concentration and so on. Meanwhile, the application of these strength agents in papermaking of wheat straw slurry was also discussed. In addition, the obvious increases in dry strength of paper comparable to using currently available cationic dry strength agents at the same dose were given by using these strength agents.
