The Effect of Nano-Cellulose on the Properties of Chemical-Mechanical Pulp*

This study was to investigate the the effect of nano-cellulose on the strength of CMP pulp and paper was produced of it. In this study, in order to supply CMP pulp Mazandaran wood and paper mill was prepared. Nano-cellulose in five levels (0, 2, 4, 6 and 8 %) of handsheets of 60 g were made and eventually physical and mechanical properties produced manufactured paper and a level of control, was tested on handsheets paper. With increasing nanocellulose, tensile strength, burst strength, air resistance, brightness and whiteness than the control samples 10.9, 12.5, 23.6, 0.6, 3.5 and 6.8% incresed. With the increase of nanocellulose tear strength, roughness, opacity, compared to the control 10.4, and 11.1, 0.6 % decresed.
