ON THE NATURE OF JOINT STRENGTH IN PAPER ¨C A REVIEW OF DRY AND WET

This paper presents a novel cationic polyacrylamide dry strength agent with anionic content (CPADSA) for papermaking. The paper describes the synthesis, characterization, and performance of CPADSA in improving the strength properties of paper. The paper also compares CPADSA with other conventional dry strength agents and discusses the possible mechanisms of action.

carrageenan as a dry strength additive for papermaking

Carrageenan as a dry strength additive for papermaking

As an anionic dry strength agent, carrageenan decreased the efficiency of some cationic retention aids such as CPAM, thus reducing filler retention. However, carrageenan is suitable for single use or in paper forming processes where Al 2 (SO 4 ) 3 is involved to enhance the strength of paper products and may be potentially used as a new additive in papermaking industry.

Application of DSA to improve strength of thermomechanical pulp blended

A more efficient application of a dry strength agent (DSA) was investigated to improve the strength of thermomechanical pulp (TMP) blended paper. Strength improvement by DSA application was more effective for hardwood bleached kraft pulp (Hw-BKP) than TMP. The degree of strength improvement of DSA further increased with the increasing degree of refining of Hw-BKP. The strength of the paper was ...

Enhance Paper Quality with Polyacrylamide

Polyacrylamide (PAM) in paper industry is widely used as retention agent, filter aid, homogenizer, and water treatment agent and so on. Its function is to improve the quality of paper, improve the pulp dehydration performance, improve the retention of fine fibers and fillers, and reduce the consumption of raw materials and environmental pollution.
