Effect of Precipitated Calcium Carbonate and Soy Protein on Properties of Writing and Printing Recycled Pulp

Recycling necessity of different paper and board grades is clear from various points of view which is accompanied with huge value addition, especially in writing and printing papers. Mineral filler applicability and its more usage in papermaking are increasingly focused and for recycled pulp, includ...
