What is a net cationic polyacrylamide dry strength agent?

Guangyan Wang and Yi Jing* A new net-cationic polyacrylamide dry strength agent was synthesized through free radical polymerization using acrylamide (AM), itaconic acid (IA), N,N-dimethylacrylamide (F), and sodium methallyl sulfonate (T).

What are cationic dry strength agents?

Cationic dry strength agents (DSAs) are commonly used for paper strengthening. However, before they are applied, another chemical called an anionic trash catcher (ATC) is often used to pretreat pulp to neutralize the negative dissolved and colloidal substances (DCS), increasing the effectiveness of the subsequently added cationic DSA.

What are the advantages of cationic polyacrylamide?

Cationic polyacrylamide in particular has an advantage in that it has a positive charge, which makes the addition of a precipitation agent such as aluminum sulfate unnecessary when used in the production of paper.

Can poly aluminum chloride be used as an anionic trash catcher?

The use of secondary fiber and rejected pulp as fiber raw material for medium paper is very economical. However, the use of reject pulp results in the breaking or removal of the fiber charge due to highly anionic in the rejected pulp. This research aims to determine the optimum dosage of poly aluminum chloride (PAC) as an anionic trash catcher.

How can cationic polyacrylamide improve fiber combination?

Studies have shown that using chemical agents is a good technique (Chen et al. 1998). Adding a polyelectrolyte, such as cationic polyacrylamide, to improve fiber combination is a promising technique (Hubbe 2006). Polyacrylamide is widely used in various fields because of its molecular structure characteristics and its many varieties.

Does a polyamine ATC deteriorate a deinked pulp?

In this paper, a deinked pulp was first pre-treated with a polyamine ATC; then, the effectiveness of two subsequently-added DSAs, anionic polyacrylamide (APAM) and cationic polyacrylamide (CPAM), were compared. Results showed that when the ATC was used alone, it deteriorated paper formation, resulting in a decrease of paper strength.
