TGfloc Series - Retention & Drainage Aids
TGsys series are a colloidal silica sol for microparticle retention program.
In the usual microparticle systems, polymers such as modified starch, guar gum, or polyacrylamide are combined with an anionic particle such as colloidal silica, alumina, and/or bentonite. In the standard application, the cationic polymer is introduced first and flocculates the fibers and fillers by bridging. After a shear stage where the flocs are redispersed, the anionic nano- or microparticle is added to reflocculate the furnish components to give very small, dense,...
