Comparing the Effect of Silica Sol and Bentonite Nanoparticles on the Performance of Cationic Starch for Drainability, Retention and Strength Properties of Recycled Paper

Production of test liner and fluting from old corrugated containers, is one of the most common paper recycling processes in Iran. This type of papers, have high basis weight and also contain significant fine fibrous and non-fibrous materials; hence, the drainage and in addition, the retention of fin...
