As a leader in water treatment and papermaking chemicals, Jiangsu Lanyao Water Treatment Co., Ltd., established in 1996 and headquartered in Wuxi, Jiangsu, has dedicated nearly three decades to the research and application of polyacrylamide (PAM) technology. By integrating advanced PAM solutions into modern paper production, the company empowers clients to achieve enhanced efficiency, reduced environmental impact, and superior product quality.
I. Core Roles of PAM in Papermaking
- Retention and Filtration Aid: Boosting Resource Efficiency
PAM acts as a bridging flocculant, significantly improving the retention of fillers, pigments, and fine fibers. Data shows that adding 0.25%-0.5% PAM increases filler retention rates from 50%-60% to 80%-90%, saving 20kg of pulp per ton of paper and reducing solid content in white water by 66%. This innovation minimizes raw material waste, extends equipment lifespan, and optimizes production processes. - Enhancing Paper Strength and Performance
As a dry-strength agent, PAM improves tensile strength, fold endurance, and burst resistance. Hydrolyzed PAM dispersants (hydrolysis degree: 20%-30%, molecular weight: 7 million) have replaced traditional plant-based glues in domestic paper mills, surpassing technical and economic benchmarks while increasing production efficiency by 10%. Cationic PAM further enhances fiber bonding via hydrogen bonds, elevating tear index and wet strength to meet high-speed printing demands. - Environmental Protection and Wastewater Treatment
PAM excels in wastewater treatment. Combined with inorganic coagulants, it reduces COD from 2,500 mg/L to below 200 mg/L and suspended solids to under 50 mg/L. Lanyao’s high-molecular-weight PAM (>7 million) effectively purifies papermaking effluents, supporting circular economy initiatives. - Versatile Applications
- Dispersant: Low-molecular-weight PAM (50,000–100,000) enhances pulp uniformity for long-fiber paper forming.
- Coating Binder: A 1:2 blend with starch improves printability and surface smoothness of coated paper.
- Emulsion Stabilizer: Adding PAM to natural latex boosts viscosity by 1.5–2 times within two weeks, ensuring production stability.
II. Technological Innovation: Modified PAM Drives Industry Advancement
To address challenges like slow dissolution and limited wet-strength performance, Lanyao has developed epoxy-modified PAM (EPAM) and amphoteric PAM (AmPAM). Lab tests reveal EPAM increases paper dry tensile index by 34% and wet strength by 142%, while AmPAM’s charge-balancing technology counters anionic trash interference, optimizing retention and filtration efficiency.
III. Client Success: Cost-Saving and Efficiency Gains
A leading kraft paper mill using Lanyao’s PAM reduced white water turbidity by 80%, saving over RMB 1 million annually. Another recycled paper manufacturer achieved a 20-fold increase in wet strength with cationic PAM, meeting premium packaging standards.
IV. Future Vision: Championing Sustainable Papermaking
Lanyao continues to innovate in neutral papermaking and bio-based material grafting, driving the industry toward low-carbon sustainability. “Our mission is to deliver chemical solutions that harmonize efficiency, environmental stewardship, and economic benefits,” stated the company’s Technical Director.
