Application of Polyacrylamide in Papermaking
Paper industry in polyacrylamide dispersing agent is composed of cationic polyacrylamide with low relative molecular weight, due to its molecular chain containing carboxyl and on electronegative fiber with dispersion effect, can improve the viscosity of pulp, is conducive to the fiber suspension and effectively improve the sheet uniformity is a long fiber of high efficient dispersant.
A retention aid, cation polyacrylamide (Percol 292), was necessary to retain ferroelectric particles in the fibrous network and improve the dispersion of strontium titanate particles. The different pulp and handsheets used were characterized according to standard methods (Pulp and Paper Technical Association of Canada, PAPTAC).
US Patent # 4,798,653. Retention and drainage aid
Retention and drainage aid for papermaking Abstract. A papermaking stock comprising cellulose fibers in an aqueous medium at a concentration of preferably about 50% by weight of the total solids in the stock including a retention and dewatering aid comprising a two component combination of an anionic polyacrylamide and a cationic colloidal silicia sol.
application of nanotechnology in the pulp and paper industry are suggesting new horizons in this area. A full scale applied example of using nanoparticles in papermaking is the well-established system of nanosilica with cationic starch. This system is now successfully used as a drainage/retention aid in plenty of paper mills using virgin pulps.
best selling ionic polyacrylamide used in mineral processing
Polyacrylamide used in mineral Processing - Polyacrylamide used in mineral Processing . Mining industry consume huge amount of water for one washing and flotation .many minerals such as iron, coal , phosphate , and diamonds are taking this processing method .
The main purposes of filler addition in papermaking are to improve paper properties and reduce cost. The cost reduction is attributed to the low cost of the filler itself and to the energy savings that occur during the papermaking process. In this work, the effects of clay filler addition on the energy savings during the papermaking process, including water drainage, pressing, and drying, were
Paper and paperboard production process and corresponding
The invention relates to an improved paper production process, according to which a branched polymer prepared in reverse phase emulsion is used as the main retention aid, and then bentonite is used as the secondary retention aid (a dual type system). The two additions are separated by a stage for shearing the fibrous suspension (or mass).
