Shouxin & Academician Shen Yinchu's Team Jointly Explore New Pathways for Developing Tailored and Stable PAM Formulations

While polyacrylamide (PAM) has become a cornerstone chemical for treating municipal wastewater and industrial effluents from dyeing, petrochemical, and mineral processing industries, a pressing global bottleneck has emerged. The significant fluctuations in pH, varying ionic strengths, and complex pollutant compositions across different wastewater systems can readily trigger a conformational shift in PAM molecules and reduce charge neutralization efficiency. This inevitably leads to unstable flocculation and uncontrolled chemical dosage. Therefore, "formulation stability" has become the critical obstacle to maximizing PAM's efficacy.

Amidst this industry-wide challenge, Shouxin has consistently enhanced its top-tier R&D capabilities by forging a specialized collaboration with a biochemical research team led by Academician Shen Yinchu, a member of the Chinese Academy of Engineering renowned as the "Father of Polyacrylamide in China". With the core objective of "utilizing targeted wastewater characterization experiments to stabilize PAM formulations",  the partnership has established a full-chain technical system spanning from laboratory research and pilot-scale validation to industrial application. This initiative drives the leapfrog advancement of PAM from "general-purpose" to "tailored, stable formulations", delivering more precise and reliable chemical solutions for industrial water treatment.

As a leading authority in biochemical engineering, the research team led by Academician Shen Yinchu provides critical support for breakthroughs at the most fundamental level. By leveraging their profound expertise in the microbial catalysis-based production of acrylamide, the team capitalizes on its strengths in enzyme engineering and the kinetics of polymer polymerization reactions. Utilizing Density Functional Theory (DFT) calculations, they precisely analyze the interaction energies between pollutants (such as dye molecules and petroleum hydrocarbons) in wastewater and the functional groups (such as carboxyl and quaternary ammonium groups) on PAM. This scientific approach establishes a solid theoretical foundation for molecular formulation design, advancing PAM formulation R&D from an "empirical trial-and-error" process to a "scientifically deduced" one.

As a specialized water treatment brand, Shouxin complements this theoretical innovation by translating it into actionable technical solutions, leveraging its industrial practice advantages. Grounded in its extensive industrial database of diverse wastewater scenarios, Shouxin focuses on the critical pain point of "insufficient formulation stability", establishing a research system centered on wastewater characterization experiments.

In the analysis phase, comprehensive parameter characterization (including pH, zeta potential, pollutant particle size, and ionic strength) is conducted to create a unique wastewater "fingerprint", pinpointing the key factors affecting formulation stability.

In the screening phase, PAM molecular structure variables are designed and formulation stability is rigorously tested through repeated static and dynamic experiments, ensuring each formulation is proven effective.

In extreme conditions, harsh environments such as high temperatures (40-80°C) and high salinity (5-15%) are simulated, with real-time performance monitoring via Gel Permeation Chromatography (GPC) and turbidimeters, guaranteeing stable efficacy even under the most demanding circumstances.

Looking beyond solving immediate challenges, the partnership is focused on the industry's long-term evolution. The collaborators envision developing an intelligent formulation adjustment model to achieve real-time adaptation of formulation parameters to wastewater characteristics, making chemical dosing more efficient and precise. Concurrently, they are conducting biocompatibility tests for biodegradable PAM, aiming to ensure environmental friendliness without compromising stability. These initiatives are designed to drive a comprehensive industry transformation from "empirical adjustment" to "data-driven, precision R&D".

This in-depth collaboration between Shouxin and Academician Shen Yinchu's team not only fully demonstrates Shouxin's strong scientific research capabilities as a specialized water treatment brand but also stands as a benchmark for how industry-academia partnerships can empower industrial upgrading. By combining groundbreaking technological leadership from the academician with the company's industrial-scale practical experience, this partnership is uniquely positioned to address core industry challenges. Together, they are setting a new benchmark for industrial water treatment chemical R&D, contributing "Chinese wisdom and solutions" to global wastewater management.
