What is a dry strength agent?

Dry strength agent is widely used in kraft paper, corrugated paper and specialty paper. It can enhance hydrogen bonding between fibers so that it can effectively improve dry strength property and physical properties of paper. Miracle’s DSR is a kind of polyacrylamide chemical with web-type structure.

What is water soluble amphoteric polyacrylamide (ampam)?

Water-soluble amphoteric polyacrylamide (AmPAM) has been widely used in papermaking as one of the agents for the improvement of dry strength.

Why is polyacrylamide a good ion-complex?

Because it makes the ion-complex with cationic additives such as wet strength resins, it is possible to clean the white water with the increased retention of fine fibers. As an amphoteric polyacrylamide of branched and high molecular weight type, it greatly improves dry strength and internal bonding strength.

Is ampam a good dry strength agent?

In this aspect, AmPAM is an efficient, multi-beneficial dry strength agent for the papermaking process, especially for secondary fibers. The consumption of secondary fiber in the paper industry has greatly exceeded that of chemical pulp or mechanical pulp recently (Göttsching and Pakarinen 2000; Pöyry 2011).

What is amphoteric polyacrylamide?

Amphoteric polyacrylamide also called zwitterionic polyacrylamide or dipolar ionic polyacrylamide. The molecular chain of the amphoteric flocculant has two or more functional groups, of which have at least one anionic charge and one cationic charge.

What is the viscosity of polyacrylamide resin?

Viscosity : 500 cps Max. As an anionic polyacrylamide resin, it is widely used in various paper making process such as printing paper, kraft paper, liner paper, etc. It improves the printability and the surface strength of paper by coating on the paper and the dry strength by using in wet-end process.
