Effect of Impregnation on the Quality of Cold Soda Pulps from Eucalyptus Tereticornis

摘要

Cold soda pulps have been prepared from E. tereticornis by employing different chemical impregnation methods. The forced penetration improves strength properties of E. tereticornis cold soda pulps. Best results are achieved with mechanical compression of chips followed by expansion of chips in NaOH solution. Cold soda pulp made from smaller size chips (match stick size) has higher strength properties.
