Advanced retention and drainage solutions for papermakers
April 10, 2018
Solenis has introduced its new MicroSolSM advanced retention and drainage solutions to help printing and writing paper producers stay competitive through increased productivity and superior product offerings. MicroSol is a revolutionary technology package that combines the company’s new patented PerForm™ SP7242 structured polymer with its uniquely structured PerForm™ MP9031 colloidal silica to give printing and writing paper producers a no-compromise solution for maximizing retention and drainage without sacrificing formation in the manufacturing process. As a result, papermakers enjoy a wider operating window that increases flexibility, improves machine efficiency and reduces operating costs.
“MicroSol builds on Solenis’ vast experience with retention and drainage aids,” said James Woodward, marketing manager, Printing and Writing – North America. “We significantly changed the retention and drainage landscape when we introduced our patented PerForm SP structured polymer in the early 2000s. Early generations of PerForm SP set the bar for first-pass ash retention. Now, with the introduction of PerForm SP7242 and our MicroSol package, Solenis is raising the bar even higher. To complement this technology, we’ve also created PerForm MP9031, a colloidal silica that adds to the retention initiated by PerForm SP yet promotes excellent drainage.”
PerForm SP molecules are highly anionic, three-dimensional structures that interact readily with cationic sites on fibres, fines and fillers in the forming paper. This structure allows the molecules to grab hold of ash and distribute it evenly to increase paper strength, retention and formation.
The PerForm MP colloidal silica offers a similar microstructure developed with attention to its size, surface area, structure, surface modification and solids content to ensure optimal performance in today’s paper machine processes. Used together, PerForm SP and PerForm MP offer a dynamic breakthrough combination that gives papermakers the ability to maximize retention and drainage without sacrificing formation.
Solenis designed MicroSol as a flexible component in a papermaker’s retention and drainage program, which could also include cationic or anionic polyacrylamide. The end result is a controllable program with a linear dosage response that offers papermakers an improved operating window with more versatility.
