Study and optimization of pulp paper composition to produce packaging paper

Abstract

The paper deals with the study of paper pulp composition influence on properties of paper based on waste paper raw materials. Application of the method of mathematical planning and solution of optimization tasks helped to establish the optimum contents of a sizing agent and cationic starch in the paper pulp composition, comprising 0.109 и0.5% of a. d. f. respectively. It is shown that the degree of paper pulp beating should be 45°ShR in order to achieve the required values of breaking length 3700 m, tensile energy absorption 34.2 J/m?, bulk 2.39 sm?/g and elongation 1.6 mm.
