Polyacrylamide Used as Dispersant In Paper Industry

Polyacrylamide (PAM) is widely used in the papermaking industry as a retention aid and drainage enhancer. Its primary functions include:1. **Retention Aid**: Polyacrylamide helps retain fine particles and fillers within the paper during the manufacturing process. This improves the efficiency of fiber utilization and reduces the amount of fines and fillers lost in the wastewater, leading to better quality paper and reduced environmental impact.2. **Drainage Enhancement**: By improving the drainage of water from the wet web of paper, polyacrylamide can increase the speed of the paper machine and reduce the energy required for drying, which can lead to cost savings and increased production capacity.3. **Improving Paper Quality**: PAM can improve the physical properties of the paper, such as smoothness, opacity, and strength. It helps in achieving a more uniform distribution of fibers and fillers, which can result in a more consistent and high-quality end product.4. **Reducing Chemical Con…
