The Role of Polyacrylamide as a Paper Strength Additive
1. Retention and Drainage Improvement:
Polyacrylamide (PAM) is widely used as a paper strength additive due to its ability to improve retention and drainage in the papermaking process. By increasing the retention of fibers and fillers, PAM helps to enhance the formation and uniformity of the paper sheet. It also improves drainage, allowing for faster water removal and reducing energy consumption during the drying process.
2. Flocculation and Fiber Bonding:
PAM acts as a flocculant, bringing together fine particles and fibers in the paper stock to form larger aggregates. This flocculation process improves the bonding between the fibers, resulting in enhanced tensile strength, tear resistance, and stiffness of the paper. The larger aggregates formed by PAM contribute to better fiber bonding, leading to improved overall paper strength.
3. Strength Enhancement:
One of the key roles of PAM as a paper strength additive is its ability to enhance the strength properties of the paper. PAM forms hydrogen bonds with the cellulose fibers, increasing their inter-fiber bonding and overall strength. This improved bonding contributes to increased tensile strength, tear resistance, and burst strength of the paper. Additionally, PAM helps to reduce the level of fines and micro-particles in the paper, which can weaken its strength.
