chemicals cationic polyacrylamide for increase paper strength
The Usage of The Polyacrylamide in The Paper Making
The polyacrylamide PAM worked as the paper strengthening agent and the dispersing agent in the paper making from the recycled papers, in order to keep the strength of the paper tensile, to keep the good performance of the paper products, and also to meet the need of the modern offset printing, you can use the cationic polyacrylamide (CPAM
Paper chemicals - Wikipedia
Dry-strength additives, or dry-strengthening agents, are chemicals that improve paper strength normal conditions. These improve the paper's compression strength, bursting strength, tensile breaking strength, and delamination resistance. Typical chemicals used include cationic starch and polyacrylamide (PAM) derivatives.
Polyacrylamide Applications in Papermaking Industry
With more adding of the anionic polyacrylamide, there is only a little influence to the paper strength, but the paper evenness gradually gets worse. 2. The polyacrylamide can be used as the reinforcing agent. As the water soluble high polymer, in recent year, the polyacrylamide is paid more attention in the papermaking industry as the
Polyacrylamide (PAM) - Water Treatment Chemicals
2.Cationic Polyacrylamide can be used as a dry strength agent, retention agent and filter agent in the paper industry. It can greatly improve the quality of paper, save costs, improve the production capacity of paper mills.

Cationic glyoxalated polyacrylamide Glyoxalated polyacrylamide (GPAM) is widely applied in a variety of paper grades to increase paper dry strength. GPAM is typically added in the pulp suspension before paper sheet formation. Upon drying the treated paper sheet, GPAM is believed to form covalent bonds with cellulose to increase paper dry strength.

Dry strength additives – Also known as dry strengthening agents are chemicals that improve paper strength of normal or not wet condition. Those strength including compression strength, bursting strength, tensile breaking strength, delamination resistance etc. Typical chemicals used are as cationic starch and polyacrylamide (PAM) delivertives.

The Usage of The Polyacrylamide in The Paper Making - CHINAFLOC. For example, use the fatty acid sizing agent 0.5, the PAM type paper strengthening agent 0.2, the aluminum sulfate 1.0 and the epoxy reinforced agent 0.7, add them into the paper making chemical pulp, make the paper product soaked in 200C for one hour, the tearing strength of the paper product can reach up to 183g, and with the
Paper Chemicals - List of Chemicals used in Papermaking
Wet strength additive – Chemicals such as epichlorohydrin, Dry strength additive – Cationic starch and polyacrylamide Coating binders – Added to provide paper with the surface that will increase water retention, and thus make paper more durable. Most commonly used agents are dextrin, oxidized starch, styrene butadiene latex, and
Dry-Strength Resins and Additives
DRY-STRENGTH ADDITIVES. Composition: The term "dry strength additives" refers to a variety of water-soluble polyelectrolytes. The term "dry strength resin" is most often used in connection with anionic copolymers of acrylamide. Acrylamide polymers, including amphoteric products (with both anionic and cationic groups), are commonly used in Japan.
Strength Problems (Troubleshooting Guide)
The primary tools by which papermakers can increase the dry-strength properties of paper are selection or purchase of a suitable quality and type of fibers, increased refining, the use of dry-strength additives, and changing the conditions of wet-pressing (if possible, given the equipment).
dry strength resin & additive – anionic & cationic
Our superior Dry Strength Resin, known as OPL DSR, is a highly sought after paper chemical that adds dry strength to paper. OPL DSR is available in three forms: anionic, cationic and amphoteric. The main function of Dry Strength Resins is to increase strength per unit of bonded area between fibers in any sheet of paper.
